When the System Fails, the Fire Starts

What would you do if your waste was not promptly collected in your area?

One day passes, and it starts to smell. One week passes, and it begins attracting pests and stray animals. When the rain comes, it blocks the drains and spreads disease. You cannot keep storing it indefinitely. You cannot simply ignore it.

So, what would you do?

For millions of people around the world, this is not a hypothetical question. It is a daily reality they face, and with all the limitations of the system around them, the easiest answer is to burn it.


Make the waste disappear

In many communities, burning waste is a daily routine, as ordinary as cooking or sweeping the front porch. Around 2.7 billion people in the world have no waste collection service at all.  When there is no bin to fill, when no trash truck comes, when there is no system ready to take the problem away, waste piles up quickly – and that pile brings its own very real, very urgent consequences: rotting food, insects, blocked drains, the spread of disease. Burning solves those problems quickly, at least on the surface. This is not careless behaviour or ignorance. It is the reality of having to choose the least bad option from a very short list.


A global problem 

Open burning is not limited to one region or one type of community. It is a global response to a global problem: too much plastic, most of it single-use, with no plan for where it ends up.

According to the Lloyd’s Register Foundation 2024 World Risk Poll, open burning is most widespread in Eastern Africa, where 41% of households use it as their primary method of waste disposal, followed by Central and Western Africa at 34%, and South-East Asia at 32%. In Indonesia, the number sits even higher than all of these regional averages, with 48% of households reported to burn their waste, despite open burning being prohibited by law.  In rural communities across Nigeria, Kenya, Ethiopia, Ghana, Nepal, and Thailand, open burning is documented as a common household practice. In rural Thailand alone, more than half of all household waste is burned. 

It also happens in places we would not expect. Open burning has been documented in Hungary, South Korea, and the United States, a reminder that this is not simply a problem of developing nations. In fact, the wealthiest countries in the world have not solved this problem either – they have largely exported it. High-income countries including Germany, the UK, the Netherlands, France, the US, Japan, and Australia have for years been shipping plastic waste abroad under the claim that it will be recycled. In 2023, Germany was the world’s largest plastic waste exporter at over 693,000 metric tons, with the UK close behind at around 615,000 metric tons. Much of that waste ends up in countries that lack the infrastructure to process it safely, where it is dumped or burned at the household and community level. Enforcement of regulations remains a major problem, with many waste exporters taking advantage of inadequate monitoring and poor border controls. The countries producing the most plastic have the least interest in dealing with where it ends up. 

 

What actually happens when waste is burned

Burning waste does not make it disappear. It just makes it less visible, and out of sight is not the same thing as gone. 

Burning waste, especially plastic, releases a toxic mix of pollutants into the air and into the soil through ash: heavy metals, styrene gas, dioxins and furans, chemicals that persist in the body and in the environment long after the fire goes out. A 2014 study published in Environmental Science & Technology found that open burning of household waste is one of the largest global sources of certain hazardous air pollutants, including polycyclic aromatic hydrocarbons and fine particles.

That last point is worth paying attention to. Fine particles known as PM2.5 are small enough to pass through the nose and throat and travel deep into the lungs and bloodstream. The WHO classifies outdoor air pollution, of which open burning is a significant contributor, as a leading environmental cause of death globally, responsible for around 3.2 million premature deaths every year.

 

The health impact, in numbers

The health data on open burning is difficult to read, and even harder to ignore.

One study estimated that open burning of waste is linked to between 270,000 and 920,000 deaths per year globally. Beyond that, open burning of plastics is linked to increased risks of heart disease and neurological disorders, while emissions including dioxins have been connected to skin lesions, cancer, immunological issues, and birth defects. 

Sadly, this burden is not shared equally. The elderly, pregnant women, and children are among the most vulnerable. So too are the people tending the fires, and the neighbours living downwind. Harm also enters through the food chain: when toxins from burning settle into soil and water, they make their way into locally grown food and into the bodies of people who never stood near a fire at all.

The exposure does not look dramatic, but it keeps happening.

This is not large-scale burning as seen in factories or industrial incinerators. There is no towering smokestack, no warning sign, no obvious signal that something harmful is happening. There are only small fires, burning close to where people sleep, eat, and play, repeated every day, familiar enough to feel normal – and that familiarity is precisely what makes it so dangerous.

This gap is not simply a story of missing lorries and underfunded councils. It is the direct result of a production system that keeps making more plastic than the world can handle, and concentrating the consequences in the places with the least power to push back. At least 2 billion people worldwide have no access to any waste collection, treatment, or disposal services. For these communities, burning is not a choice. It is an inheritance. 

The packaging problem makes everything worse. For most of human history, there was no need for large-scale waste collection. Most waste was organic, and what could be reused, reused. But single-use plastic packaging flooded markets far faster than any infrastructure could keep up, especially in island communities and rural areas where collection systems are expensive to build and even more expensive to maintain. Global municipal waste generation is projected to grow from 2.3 billion tonnes in 2023 to 3.8 billion tonnes by 2050, almost all of it driven by packaging and single-use materials landing in places that have no system in place to receive them.

And the companies that make that packaging? They have known about the problem they cause for a long time, but the burden of dealing with it has been consistently shifted, first onto public bodies, then onto households: manage it yourselves, find a way to make it disappear. 


What can help, for now

There are small changes that can reduce the harm while the larger system gets its act together. Separating organic waste for composting and keeping plastic out of the fire entirely, significantly lowers exposure to dioxins, furans, and heavy metals.

This is not a complete solution, but it is not nothing either. Reducing the most toxic emissions is one small, real part of addressing the harm, even if it cannot address the system that causes it. For someone standing in front of a pile of waste with no bin to fill and no trash trucks coming, it is worth knowing. 

 

The bigger picture

People who burn waste are not choosing pollution. They are not choosing to harm their neighbours, their children, or themselves. They are trapped in a system that was never built for them, one that was flooded with cheap plastic packaging without any consideration of its safety, or the infrastructure available to handle it.

Waste should not be managed at the point of burning. It should be prevented at the point of design. Better collection systems can ease the immediate harm, but they are a temporary fix to a permanent flow. The only real answer is less plastic being made in the first place, and producers being held accountable for every piece they release into the world. 

Until products and systems change, the harm will keep being pushed onto the people with the fewest choices, and they have already been carrying it long enough.

The plastics crisis is also a women’s health crisis

by Fayrouz on 08/04/2026 No comments

We often talk about plastic pollution as if it is only an environmental problem – or a waste problem, something that only matters at the end of a product’s life. Uncollected or poorly managed waste contaminates air, soil, and water sources. Plastic waste, small and large, is found in the bodies of sea turtles and various marine animals. At its core, all of these are real and urgent problems, but sometimes we forget that there is another story that is far closer than other plastic problems, which is the problem of waste that silently lives inside our bodies.

Every day, our bodies are exposed to tens of thousands of petrochemicals – synthetic chemicals derived from petroleum and gas that are used to make plastics, packaging, cosmetics, cleaning products, and more. We encounter them through the products we use, the food we eat, and the air we breathe. This applies to everyone, but unfortunately, the impact is not the same for everyone.

The fact is, women’s bodies process these chemicals differently. Women tend to have thinner skin, so chemicals found in products that come into contact with their skin are more easily absorbed. Women also have a higher percentage of body fat, so more fat-soluble plastic chemicals such as phthalates and BPA, end up absorbed and stored inside their bodies. Women also typically have smaller than average body sizes, causing the concentration of those chemicals to be higher. And a slower metabolism means women’s bodies take longer to eliminate them.

These facts are not merely biological footnotes we can ignore because they sound too ordinary. They must change how we think about who bears the real cost of the plastic crisis.

 

The body stores everything we experience

Plastic is full of endocrine-disrupting chemicals – substances that interfere with our hormones.  For women, whose health is so closely tied to hormonal balance throughout their lives, this disruption can be deeply damaging.

During puberty, pregnancy, and perimenopause, women’s bodies are in a state of change, meaning even the smallest toxic exposure during these important moments not only adds risk but also multiplies its effects. These chemicals are linked to fertility problems, certain cancers, and diabetes. They can ultimately also trigger early menopause and worsen symptoms like hot flashes and mood swings.

Sadly, this impact does not stop at one generation. Women unknowingly pass toxins from their bodies to their children during pregnancy and breastfeeding: a journey that women always remember in their lives becoming a silent transfer of toxins, even before their babies breathe air outside the womb.

 

Home is no longer a safe place

Traditional domestic roles place women in closer and more frequent contact with chemicals found in various household necessities such as cleaning products, packaging, synthetic rubber gloves that are ironically sold as “protection” – but actually become a new source of exposure.

Plastic chemicals are used in product formulas to create fragrance, colour, texture, and longer shelf life and are rarely tested for safety before reaching our hands.

Then there is the beauty sector. Marketing pressure deliberately targets women, endlessly pushing them to buy cosmetics, personal care products, fragrances, and hygiene products that almost all contain petrochemicals and are packaged in plastic. Even the most basic hygiene products are not spared from this danger: most sanitary pads and tampons that are affordable and easily accessible to the general public actually contain plastic that is harmful to their bodies.

More than 16,000 chemicals have been identified in plastic, and most of these substances have never been tested for safety regarding direct and indirect exposure for humans, more specifically, women. Of those, a quarter are already known to be hazardous but only 6% are regulated. The rest? No one is checking.

With no strong regulation or clear labeling of ingredients on products and packaging, there is no obvious way for women to know or understand the risks involved in their daily routines.

 

The health costs of earning a living

Women are the dominant workforce in industries with high chemical exposure: cleaning, waste management, textiles, agriculture. Many of these jobs are informal in nature which means they  have no regulations to ensure workers’ health and safety.

These jobs most often come without adequate personal protective equipment, are not covered by occupational health services, without sick leave, and without information about the risks they can and will face. Long working hours mean continuous and intense exposure to various toxins. These kinds of jobs are also usually low-paying, leaving workers with little power to change the situation.  

Globally, the majority of waste pickers working at open dumpsites are women. WECF reports that many of them cannot live past the age of 30, and this is not a statistic from an era that has passed: it is still happening today.

 

Same plastic, unequal impact

The plastic crisis does not discriminate in who it touches, but sadly it is very selective in how hard it hits.

Women bear a disproportionate chemical burden – through their biological body systems, the domestic roles they carry, the working conditions they must face, and the non-essential products they are told they need. With this many negative effects, women are still too rarely part of the conversations that decide what is produced, what is regulated, and what is labeled.

To change this, we need more legal protections for high-risk workers. We need honest product labeling. We need health and safety standards that actually apply to informal workers. And we need more women in the rooms where decisions and regulations about chemicals and production are made.

The plastic crisis is a women’s health crisis, it always has been. The question is, how much longer will we pretend otherwise?

Why “plastic is more eco-friendly than glass” is a misleading claim

by Seema on 31/10/2025 No comments

We often hear that plastic bottles or packaging are more “eco-friendly” than their glass counterparts, primarily because plastics are lighter and (so the argument goes) create fewer greenhouse gas emissions in production and distribution. But a closer look at these “life cycle assessments” (LCAs) makes it clear that this narrative is flawed in several fundamental ways. In particular, work by the UN Environment Programme (UNEP) and the Life Cycle Initiative has shown that focusing only on a narrow set of impacts obscures the broader environmental harms of plastics and fails to capture the advantages of reuse systems.

So what are the pitfalls of the “plastic is greener than glass” claim?

1. Narrow focus on climate impacts

Many “plastic versus glass” studies focus on one core metric: carbon or greenhouse gas (GHG) emissions. Because plastics are lighter and require less energy for transport, they often appear to have a lower carbon footprint than glass, at least in the framing used by the researchers.

But climate impact is only one of many categories a robust environmental assessment should cover. Other key impact areas – toxicity, biodiversity loss, ecosystem degradation and the social or justice dimensions of pollution (harms to communities, waste pickers, Indigenous Peoples) – are often downplayed or excluded entirely as they are difficult to measure and quantify.

Plastic LCAs for example typically omit leakage into the environment, which happens at all points in its life cycle – from pellet spills (the second largest source of microplastics in the ocean) to shedding and leaching during use and litter. Leakage is one of the most damaging and irreversible impacts of plastics, leading to ingestion by wildlife, entanglement, fragmentation into persistent microplastics and cumulative ecosystem harm.

2. Over-reliance on LCAs as a decision-making tool

LCAs, as noted above, are not designed to capture the full system of impacts. They need to be supplemented with additional studies and knowledge to give a full picture.

But even the insights they provide using indicators such as energy and water use, or emissions and resource extraction, should not be taken at face value. The system boundaries and assumptions in each study make a huge difference: what production processes, what end-of-life scenarios, what transport distances, what reuse rate have been assumed? Minor shifts in assumptions can flip the results.

LCAs can also, intentionally or not, hide “burden-shifting”: improving one impact category (e.g., lowering GHGs) may worsen another not included in the study (e.g., ecotoxicity, microplastic release). Indeed, the UNEP meta-study warns, “like any tool, [an] LCA does not replace the need to draw upon a range of information sources when making decisions.”

So when someone cites an LCA that says “plastic is better for the climate”, the key questions are: “what have they left out? What were their assumptions? What alternatives did they model? And do those reflect the system we could realistically move towards?”

3. False comparison: single-use glass vs single-use plastic

Another shortcoming of many LCAs is that they compare single-use glass with single-use plastic, with the typical end-of-life scenario being recycling. In reality, glass can be reused tens if not hundreds of times before needing to be recycled.

Why does this matter? Because reuse avoids the vast majority of any material’s climate impacts, particularly the energy-intensive melting process of glass. Instead, reuse only requires washing, drying and local transport. These impacts are far lower, and are declining further as energy grids decarbonise and reverse-logistics systems improve. Meanwhile plastic production remains closely linked to fossil-fuel extraction and refining, global supply chains, and a poor 9% recycling rate, much of it shipped to countries in the Global South.

In short, if we make a more realistic comparison between single-use plastic and reusable glass, the advantage swings firmly towards glass plus reuse systems.

4. Ignoring business models and system design

A major methodological flaw in many LCAs is the assumption that the business model will be the same for the existing and replacement materials. That is, they compare plastic bottles shipped long distances to glass bottles shipped in exactly the way. But what if that’s not the way it would work?

For example, if we slot heavy glass bottles into a conventional global production-and-distribution model, they will naturally perform worse than plastic if shipped halfway around the world for a single use. That’s because this model was built around and optimised for single-use plastics. But glass functions best with local bottling and refilling, reverse logistics, and much smaller distribution networks.

If the comparison privileges the status quo, rather than the alternatives we may prefer to cultivate, it skews the results. If we want a better system (reuse and refill within local networks) then this is what should be modelled. A comparison of materials within the existing system is not going to make sense.

5. The broader issue: redefining “eco-friendly”

Ultimately the myth that “plastic is greener than glass” stems from a too-narrow definition of what “eco-friendly” means. If we define it purely as “the lowest carbon footprint in today’s system”, plastics could emerge as a winner. But if we define it in a way that includes:
– chemical toxicity
– persistent pollution and ecosystem damage
– leakage and microplastics
– resource circularity
– reuse potential
– environmental justice
– future-proofing (energy decarbonisation, logistics innovation)
then the narrative changes dramatically.

The UNEP/Life Cycle Initiative recommendation emphasises this clearly: the priority is reuse, reducing single-use products, and system redesign, regardless of the material.

➤ Cut through the greenwashing

When you see a claim that “plastic is greener than X material” ask these questions:
– What impacts were assessed (just GHGs, or also (eco)toxicity, persistent pollution and social / health outcomes)?
– What was the alternative material and was it reused or used once and recycled?
– What system design assumptions were built in (transport distances, reuse, decarbonised energy)?
– What life-cycle boundaries were applied (upstream fossil-fuel extraction, pellet loss, end-of-life leakage)?
And lastly: what if we changed the system, would the result still favour plastic?

When the full picture is taken into account, the “plastic is greener than glass” claim collapses. The more constructive agenda is not material substitution alone, but system change: moving away from single-use, designing for circularity and investing in local infrastructure enabling safe reuse, refill and repair.

We have now crossed 7 out of 9 planetary boundaries

by Seema on 14/10/2025 No comments

During the Holocene epoch, spanning the last 10,000 years, conditions on Earth have been remarkably stable. That stability allowed human societies to flourish: grow food, trade and build cities. But as unchecked capitalism pushes the planet beyond its safe limits, we risk tipping it into instability, with consequences for every living being.

Last month, scientists confirmed that humanity has now crossed seven of the nine planetary boundaries – thresholds beyond which the Earth’s environment can no longer self-regulate and may become unliveable.

But what exactly are these boundaries, and why does crossing them matter?

The concept of planetary boundaries was first introduced in 2009 by a group of internationally renowned environmental and Earth system scientists. The framework identifies nine critical processes that together form the planet’s life support system, regulating its stability and resilience. Each process has a “safe operating space”, the conditions that ensure the system works smoothly.

Leaving this space doesn’t mean immediate catastrophe, but it increases the risk of abrupt, non-linear and potentially irreversible environmental change. In other words, the further we push past these limits, the more likely we are to trigger tipping points that could undermine the very systems on which we depend for survival.

The nine planetary boundaries and where they stand in 2025

1. Climate change ➡︎ boundary exceeded
Our climate system regulates temperature, rainfall patterns, sea levels and the functioning of ecosystems. Human-driven greenhouse gas emissions, especially carbon dioxide and methane, and airborne pollutants are trapping heat in the atmosphere that would otherwise have escaped into space, pushing global temperatures well beyond the stable Holocene range.
How this manifests: extreme weather events, flooding, wildfires, rising sea levels, desertification. The rate of ocean warming has doubled over the past 20 years.

2. Novel entities (chemicals and plastics) ➡︎ boundary exceeded
This category includes petrochemicals, all types of plastics, genetically modified organisms and other synthetic substances that are not biocompatible and often very harmful to living things. Many persist in the environment, forming toxic cocktails and contaminating entire ecosystems.
How this manifests: widespread pollution from micro- and nanoplastics and PFAS (“forever chemicals”) in the water, air and soil.

3. Stratospheric ozone depletion ➡︎ currently within the safe zone.
The ozone layer shields life on Earth from harmful ultraviolet radiation from the sun. International action to reduce the production of ozone-depleting chemicals since the late 1980s and through the Montreal Protocol has successfully helped the layer to recover to within a safe operating space.

4. Atmospheric aerosols (air pollution) ➡︎ globally within the safe zone; exceeded in some regions.
Aerosols are tiny airborne particles such as dust, soot, sulphates and smoke. They affect air quality, human health, and regional climate patterns. This boundary is currently exceeded in many densely populated areas, especially those with heavy industrial and fuel incineration emissions, but globally is considered within safe limits.
How this manifests: increased respiratory and other disease, exacerbation of climate change, changes to monsoon systems. One out of five early deaths is due to fossil fuel air pollution.

5. Ocean acidification ➡︎ boundary exceeded
The oceans absorb carbon dioxide from the atmosphere. This makes seawater more acidic, which prevents corals, shellfish and some plankton from building and maintaining shells and skeletons, with devastating knock-on effects for those further up the food chain – including coastal communities. In the 2025 Planetary Health Check, the ocean was found to have increased in acidity by 30-40% since the start of the industrial era, making it the seventh boundary now judged to be in the danger zone.
How this manifests: coral bleaching and death of tropical reefs, Arctic marine life under threat, food insecurity.

6. Biogeochemical flows ➡︎ boundary exceeded
This process describes how essential elements and compounds cycle through the Earth’s systems. Nitrogen and phosphorus are key nutrients for crops, but their overuse in industrial fertilisers has led to pollution, soil degradation and so-called dead zones in oceans and lakes.
How this manifests: algal blooms caused by fertiliser run-off deplete oxygen and kill aquatic life, increased ocean acidification, infertile soil. There are currently more than 500 identified ocean dead zones, covering 95,000 square miles.

7. Freshwater change ➡︎ boundary exceeded
Freshwater availability and flow – both above, in and below the ground – are essential for agriculture, human consumption, and ecological stability. Pollution, dams, land conversion, over-abstraction and climate change have led to freshwater ecosystems being degraded in half the world’s countries.
How this manifests: droughts, floods, degradation of water quality, loss of wetlands and mangroves. 25% of freshwater species are facing extinction.

8. Land-system change ➡︎ boundary exceeded
Around three quarters of natural landscapes on our planet have been “modified” for human use over the past millennium. This involves permanent changes such as urbanisation and potentially reversible changes such as the clearance of tropical rainforests for agriculture such as soy and palm oil.
How this manifests: soil erosion and degradation, habitat destruction, desertification, forced migration, increased global warming. Global forest cover is now far below the 75% safety zone.

9. Biosphere integrity (loss of nature and biodiversity) ➡︎ boundary exceeded
The biosphere is the living layer of Earth and requires a large, broad and diverse range of healthy organisms to underpin food production, pollination, disease regulation and countless ecosystem services. Biodiversity loss means the system is less able to self-regulate and recover from shocks.
How this manifests: poor crop yields (and food insecurity), accelerating species extinctions, ecosystem collapse.

A wake-up call, not the end

These processes are all interconnected. Pressure on one will inevitably lead to pressure on the others.
Crossing the seventh planetary boundary means that humanity is accelerating the deterioration of Earth systems, and moving further away from the stable conditions that made civilisation possible.

Unsurprisingly, having more than 3/4 of the lights on the dashboard flashing red increases whole system risks: we can expect to see more frequent extreme weather events, reduced resilience of ecosystems, greater water and food insecurity, and the possibility of triggering tipping points such as ice sheet collapse or rainforest dieback.

Yet the planetary boundaries framework is not a prediction of inevitable disaster; it is a risk management tool. We can use it to build momentum to bring systems back into the safe zone. The two intact boundaries are testament to this. Stratospheric ozone depletion – once close to its limit – has been brought back within a safe operating space, thanks to decades of international cooperation through the Montreal Protocol. Collective action on the other processes, which requires deep and rapid cuts in fossil fuel use (for both energy and plastics), can bring back Earth systems within safe limits – but the clock is ticking.

As Johan Rockström, Professor in Earth System Science, who led the development of the planetary boundaries framework says: “even if the diagnosis is dire, the window of cure is still open. Failure is not inevitable; failure is a choice. A choice that must and can be avoided.”

Do facts really change people’s minds? How to communicate about plastic pollution

by Lydia on 07/07/2025 No comments

We live in a world that often feels deeply divided. Whether it’s about politics, economics, or social issues, the gaps between us seem wider than ever. Sometimes even within our own families. It can be tempting to try and correct people who have succumbed to online disinformation with the facts.  But if you’ve ever tried to convince someone with data only to see them dig their heels in, you know it’s rarely that simple. Facts, if delivered at the wrong time or with the wrong sentiment, can make differences even more entrenched. 

Today, we’re exploring this as a reminder to ourselves and everyone who is working to change the status quo. Because while knowledge is power, emotional intelligence is a superpower

Why facts aren’t always enough

We often assume a simple chain reaction: if people know, they’ll care, and if they care, they’ll act. But the reality is much messier than that. 

While truth is vital, and knowledge matters – especially at a time when the world is flooded with disinformation – bombarding people with facts can often backfire. Environmental organisations, for example, often publish horror stories about pollution, toxic chemicals or climate change. 

But the truth, when it feels too overwhelming, scary or inconvenient to face, can cause people to shut down rather than engage. We go into fight, flight or freeze mode – a natural human response to protect ourselves from what feels unmanageable. 

Being told about a problem doesn’t automatically lead to action, especially when the scale of change feels too big, too hard or too lonely. 

What stops people from acting? 

It’s this feeling of powerlessness or lack of clear direction that turns people off. People can’t act if they don’t know what to do, or if they genuinely believe their actions won’t make a difference. 

Here are some common assumptions that can hold us back: 

  • “Change will be expensive and mean sacrifice” The perception that living more sustainably or advocating for change will be a financial burden or require giving up comforts. 
  • “Whatever I do won’t make a difference one way or the other”. A paralysing sense of futility, that leads people to believe their individual efforts are insignificant against global challenges.
  • “It’s easier to stay in my bubble than face the crisis” An avoidance tactic – it’s human nature to seek comfort and avoid discomfort. Facing daunting realities can be emotionally draining.

Those with vested interests in keeping business as usual will also exploit and reinforce these beliefs on their own media channels. They will either deny the science altogether, or invest it with incredible powers: “science will come up with a solution, we don’t need to do anything.” This both reassures people and frees them from guilt and obligation.

So, what does work? 

To spark bottom-up action, people need more than just facts: they need support, motivation and a sense of agency. This is something we have experienced first-hand in Trash Hero, working in communities often resistant to change.

Here’s how we try to engage people in our mission: 

  1. Empathy and connection: hold the judgement

Instead of asking “Why do you do that?” or telling someone “You’re wrong”, approach conversations with compassion and curiosity. We are all shaped by the systems around us. Inspiration moves people, whereas fear and shame often freeze. 

  1. Connect with identity and values, before presenting facts 

People are most likely to act when their behaviour aligns with who they are, or who they want to be. We encourage our volunteers to share their own “why” – their personal motivation for wanting change – and tell stories about justice, community and courage. These narratives provide hope, which isn’t naive: it’s a powerful motivator. 

  1. Lead by example

Actions truly do speak louder than words. We are social creatures, and we learn by observing others. When people see us composting, using reusable items, or speaking up respectfully, it makes these actions feel possible and normal. 

  1. Make it easy and social 

Behaviour change spreads when it feels normal, visible and supported. When reducing waste is made simple and becomes a shared activity, it fosters a sense of belonging and makes the journey less daunting. Eventually, we will reach a tipping point – and when culture shifts, systems often follow. 

  1. Small steps with visible impact and repetition

Huge, overwhelming goals can paralyse us. Small, achievable steps that have a visible impact – like cleanups with education – help us move forward. Consistent action builds habits and trust and reaches a wider audience over time.

  1. Relevance to everyday life 

People need to feel that environmental issues are connected to their daily experiences. How does plastic pollution affect their local park, their health or their community? When people can see the immediate relevance of an issue to their own lives, it becomes more personal and pressing.

Be the change, inspire the change 

The truth matters, but so does how we share it. Big change starts with better conversations. We need to use our compassion, connection and consistent modelling alongside our knowledge and data in order to be effective. This takes time and patience, but eventually has better results than trying to “win” an argument, blaming or gimmicks.

We’ve summarised these findings in a social media post, along with some case studies of effective environmental campaigns – please share to help more people understand the power of emotional intelligence in the zero waste movement. And follow us online to keep yourself inspired!

Why extended producer responsibility (EPR) isn’t working – and how we can fix it

by Seema on 07/05/2025 No comments

Wherever you’re reading this, stop and take a look around you. You’re likely surrounded by products deliberately designed for short lives: packaging thrown in the trash after a single use, electronics with built-in obsolescence, appliances that can’t be repaired and fast fashion that unravels after a season.

For decades, Extended Producer Responsibility (EPR) was touted as the solution – a policy tool that makes producers pay for the environmental cost of their products. The theory is simple: if companies are made responsible for their products after use, they will design better, longer-lasting, less polluting products.

But that’s not what happened in practice. A new report by Zero Waste Europe, which analyses the past 30 years of EPR implementation in the EU and beyond, shows waste levels are still rising, recycling rates are stagnating, and reuse rates have actually fallen drastically over this time1. Many producers have simply paid fees to comply – without improving how they design, deliver or market their products.

Something has gone seriously wrong. The potential of EPR remains powerful – but today’s systems need a major rethink if they are to live up to their promise.

What is EPR?

Extended Producer Responsibility (EPR) is exactly what it sounds like: extending the responsibility of manufacturers beyond the point of sale. Instead of letting products become someone else’s problem at end-of-life, EPR policies make companies responsible – financially, logistically, and sometimes physically – for what happens to their products and packaging after consumers finish using them.

Originally, this was intended to make the environmental impacts of products a business cost, thereby creating incentives for producers to design products that are easier to reuse, repair, and recycle – with the ultimate goal of preventing waste in the first place.

But too often today, this “responsibility” has been watered down. Companies have ended up paying nominal fees to fund waste collection, take-back programmes or a few extra recycling bins – effectively a “pay to pollute” scheme.

How the current system works

Today, most EPR schemes work like this:

  • Producers pay fees into a collective system, often run by a Producer Responsibility Organisation (PRO).
  • The PRO funds the collection, sorting, and recycling (or disposal) of waste products.

Producers claim this ‘closes the loop’ – but in reality, the system has serious flaws:

  1. End-of-life The focus remains heavily on recycling, not on preventing waste or promoting reuse. This treats waste as inevitable, rather than something to be avoided through better design and infrastructure. As the Zero Waste Europe report shows, implementing EPR without reuse targets has had the effect of making reuse the least favoured option.
  1. Fee structures Producers often pay based on weight or general material type (e.g. ‘metal’ or ‘plastic’), without strong enough “eco-modulation” to reward truly sustainable designs and penalise bad ones. This weakens the incentive to innovate.
Eco-modulation adjusts EPR fees based on the environmental performance of individual products, making it cheaper to do the right thing, and more expensive to pollute. Example: a reusable glass bottle = lower EPR fee. A multilayer plastic sachet that can’t be recycled = much higher EPR fee. The goal is to create a strong financial incentive to design products that are better for the environment – not just to manage waste but to prevent it.
  1. Lack of regulation Many PROs are industry-controlled and self-regulating, leading to a conflict of interest. Producers have little motivation to set ambitious reuse targets or high environmental standards when they effectively police themselves. At the same time, the revenue they provide to the government gives them a platform for lobbying and allows them to claim that “something is being done”.
  1. Lack of transparency It’s often unclear what PROs’ targets are (e.g. is “recycling” measured at the collection point or on delivery to a recycling plant?); whether they are being met; how funds are being used; or what really happens to the waste collected. As a result, municipalities and taxpayers still shoulder much of the burden of management. Fraud and greenwashing are real risks.
  1. Lack of integration It is very rare in current EPR legislation that the treatment of the collected waste is specified or controlled. PROs can therefore follow any existing waste management laws, whether these send plastic for incineration or closed loop recycling. In other words, EPR can only work well if there is already a good waste management system in place.

So at best the current EPR system locks us into endless waste management and does nothing about waste prevention, resource efficiency or a just transition; at worst it actively fights against these outcomes.

How we could make EPR work

EPR can still play a major role in creating a circular economy, but only if it’s fundamentally restructured to follow the waste hierarchy, with prevention first. This is what it would look like:

Priority for prevention and eco-design: The first goal is to reduce the amount of waste we generate. EPR funds help build reuse systems, refill networks, and repair services – not just more waste treatment infrastructure. EPR fees strongly encourage reusable, durable, and non-toxic designs.

Strong eco-modulation: Fees clearly reward sustainable products and penalise polluting, wasteful ones, sending tangible financial signals to drive better design.

Deposit return schemes (DRS): Consumers pay a small surcharge for packaging and are thus incentivised to return it to a collection point in order to get a refund, enabling producers to preserve reusable items or ensure high quality recycling. (DRS are a type of EPR and are proven to be the most efficient and effective way to achieve high collection rates of packaging. Many countries that have implemented a DRS have achieved collection rates of over 90%.)

Clear, ambitious targets: Mandatory targets for waste prevention, reuse, recyclability, and toxic material phase-outs are at the core of EPR legislation, not just recycling rates. Targets are clearly defined (i.e. when and how they are measured), progressive and ensure the local waste management system is equipped (or can be over time) to deal with them effectively.

Independent governance: Producer Responsibility Organisations are independently managed and regulated, with strong public oversight to avoid industry capture.

Transparency and public accountability: Open access to data, third-party verification and monitoring and meaningful penalties for non-compliance is standard.

Integration with other policies: EPR is one piece of a wider resource management strategy, considered together with waste management, climate, health and other material resource policies, so they are all compatible. Bans, cap and trade, production reduction, reuse targets, taxes and other policy instruments are used alongside EPR to mutually support circularity.

If EPR systems are redesigned along these lines, they can become powerful drivers of innovation, sustainability, and climate action instead of a symbol of greenwashing and weak “pay to pollute” policymaking. The Global Plastics Treaty negotiations will play a key role in determining whether this happens.

It seems obvious that producers must be held responsible not just for managing their waste – but for creating less of it to begin with. Truly extending their responsibility means looking beyond “recycling” to designing products and building infrastructure, like DRS, that make circularity the easy choice, not the exception.

Plastic on TV: it’s time for a change

by Lydia on 10/04/2025 No comments

What image comes to mind when you picture a successful, busy character in a TV show? For many, it’s someone striding into an office, mobile phone in one hand and a disposable coffee cup in the other. This image of success and power has been reinforced by decades of TV and film. Think of Miranda Priestly in The Devil Wears Prada: a high-powered woman whose assistant fetches her very specific coffee order every day in a single-use cup. This is just one example of how props function as symbols of character and status. A throwaway lifestyle signifies success, but is this the right message to be sending audiences? And in general, given what we now know about its impact, should single-use plastic be presented on screen as a positive – or even neutral – part of society?

Media’s role in normalising behaviour 

“We are shaped and formed by what we watch”- Diana Cohen, Co-founder and CEO of the Plastic Pollution Coalition (PPC). 

The media has the power to normalise or demonise behaviours. Characters become popular because people relate to them, idolise them and want to be like them. Take smoking: once a symbol of the “cool” character (e.g. Danny Zuko in Grease), its use on screen shifted with growing awareness of health impacts. Regulations limited its presence, and depictions changed. Broadly speaking, it became a symbol of weakness, struggle or villainy.

How is plastic portrayed on screen? A 2021 PPC study found that 93% of plastic shown in a sample of popular TV and films from 2019-2020 was not disposed of on screen. Of the 7% that was disposed of, 80% was littered. This gives the audience two messages: 

  1. That plastic simply “disappears”.
  2. Irresponsible disposal, like littering, is acceptable. 

Since then, knowledge about plastic’s impact on our planet, climate and health has grown massively and the public’s attitudes towards plastic have also shifted. It’s clear TV and film producers need to catch up. Let’s look at some recent popular TV shows and how they have, or haven’t, addressed single-use plastic.

Direct references to reuse culture

Hacks (2021-present) uses the age gap between young writer Ava and veteran comedian Deborah to discuss a variety of environmental issues. In early episodes, Ava chastises Deborah for always getting single-use plastic cups for fizzy drinks and persuades her to get a reusable cup instead. In “One Day” (season three, episode five), Deborah initially dismisses climate change: “the Earth is a billion years old. It just self-corrects from any damage that’s done to it…Trust me, we’re fine”. Ava gradually educates her, and in the closing scene, Deborah reprimands her makeup artists for using plastic. These conversations are not clunky or forced. As The Hollywood Reporter notes, the show seamlessly integrates “deeply felt activist stances” without sacrificing comedy. 

Quietly sustainable: the power of visual cues

Of course, reuse doesn’t have to be talked about directly by the characters to have an impact. By simply showing reuse in action, Shrinking (2023 – present) and Abbott Elementary (2021- present) make it feel natural and commonplace. In Apple TV’s Shrinking, Gaby’s “emotional support water bottle” is a recurring feature, but its environmental impact is not explicitly mentioned. Instead, the characters discuss how hydrated Gaby is, and she uses it as a way to bond with one of her colleagues.

Planet-friendly behaviour is seen regularly in Disney’s Abbot Elementary. The teachers all have reusable coffee cups, the staff car share or walk to events, and there is a school garden project. While some single-use items are still present on screen, in general, sustainable choices are the default option without making any particular fuss about it. Having popular, likeable characters associated with reuse sends a powerful message to audiences.

In comparison, Only Murders in the Building (2021 – present), like most shows, missed an opportunity to show reuse as a standard option. The Disney show centres around a friendship between Charles and Oliver, in their 70s, and Mabel, in her early 30s. They frequently use disposable coffee cups and cutlery. Like in Hacks, the writers could have used the age gap to spark conversations about reuse. For example, Mabel could carry a reusable coffee cup while Oliver and Charles take single-use – the outdated option. Or they could have had characters of all ages using reusable cups and cutlery – normalising the behaviour across generations. 

Perhaps in the future we might even see whole reuse systems in action in popular TV shows and movies?

Behind the scenes

Who can forget the famous Starbucks coffee cup left on set in Game of Thrones? The TV and film industry is known for waste. A typical 60-day shoot uses 39,000 single-use water bottles. On top of that, large quantities of disposable plastic plates, utensils and coffee cups are used every day on set. Quinta Brunson, creator, writer and star of Abbott Elementary, has been open about the need for change in the industry. She is leading by example, providing reusable water bottles for everyone on her set. Lucia Aniello, showrunner for Hacks, also supports sustainability. She worked with the studio to reduce waste by eliminating plastic water bottles on set and having characters repeat outfits. Changes we want to see on screen should be mirrored by changes off screen. 

What needs to happen? 

Given the well-documented health and environmental harms of plastics, the way they are portrayed on screen needs to be addressed. Producers should consider their depiction with the same responsibility now applied to tobacco and alcohol. If they acknowledged their duty it would undoubtedly help to make sustainable behaviours more mainstream. It would also reflect the attitudes of growing numbers in their audiences who are concerned about single-use plastics. 

As viewers, we should be aware of how single-use plastic is portrayed on screen.  The Begley-Cohen Test, developed by the PPC, encourages the critical evaluation of single-use plastic in the media.

To pass the test, the following criteria must be met:

  1. No single-use plastics appear on the screen
  2. If single-use plastic does appear on the screen, it is portrayed or discussed as problematic

Try it on the next thing you watch and share your findings! The stories we see on screen can be shaped by pressure from the people who watch them. Films and TV shows are both a reflection and an important driver of aspirations. And what better goal to have than a world free from plastic pollution?

How plastic is causing climate breakdown

by Lydia on 12/02/2025 No comments

The last ten years have been the hottest on record, and 2024 was the first year to surpass the 1.5-degree Celsius warming threshold that scientists have suggested will trigger irreversible damage to ecosystems. The impact is evident. From catastrophic floods in Central Europe and heatwaves across Southeast Asia to droughts in West Africa and devastating wildfires in Los Angeles, recent years have delivered an onslaught of life-threatening extreme weather events. These are not “natural disasters”, as often reported, but highly unnatural events caused by climate breakdown. 

In this blog post, we’re going to explain how plastic production is driving climate change and why its impact has flown under the radar for so long. 

Emissions from fossil fuels are the leading cause of climate change; and fossil fuels are the building blocks of 99% of all plastic. Global plastic production is nearing a staggering 500 million tonnes annually and is projected to triple in the next four decades. The plastics industry is the fastest-growing source of industrial emissions, already responsible for up to 8% of the global total – many times more than the 2.5% produced by the aviation industry. If plastic production increases as projected, it will consume the world’s entire carbon budget by 2060, or at the very latest 2083. This means that even if every other industry were to completely decarbonise, the plastic industry alone would still produce enough to push global warming past safe limits.

Where do the emissions come from?

Plastic generates greenhouse gas emissions at every stage of its lifecycle, from fossil fuel extraction and production, to when it is being used and finally disposal.

Over 90% of the greenhouse gas emissions attributed to plastic are released before it even reaches the public – during the production stage. The process of extracting fossil fuels, refining them and manufacturing the plastic products themselves is incredibly energy-intensive. 

The role of the plastics industry

Investigations have revealed the plastics industry has a history of hiding its environmental and climate impacts. The connection between fossil fuels and climate change has been known for decades, with oil companies themselves aware of the link since at least the 1970s. Yet, they publicly denied any knowledge and continued to invest in and promote fossil fuel industries such as plastic. To protect their market, and their profit, they spent millions blocking plastic bans, lobbying against producer responsibility legislation and obstructing the Global Plastics Treaty. They also created organisations such as the American Chemistry Council and the Alliance to End Plastic Waste (AEPW), which actively promote climate change denial and misinformation.

AEPW, formed in 2019 and funded by major oil and chemical companies like ExxonMobil, Shell and Dow, actively promotes recycling and waste management initiatives – despite knowing since the 1980s that recycling plastics could never be a long-term solution. This is a classic case of greenwashing, deliberately misleading the public about the safety and sustainability of their products in order to continue producing them.

The plastic industry’s deception doesn’t end there. They invest in and promote false solutions like chemical recycling and “waste-to-fuel” technologies. These initiatives, while presented as innovative, actually perpetuate the need for waste, especially plastic. They also promote “biodegradable” and “plant-based” plastics most of which contain fossil fuels. All of this distracts from the real issues and ensures a continued market for their plastic production.

What needs to happen? 

Preventing complete climate breakdown depends on urgent and drastic cuts in plastic production. While we can take steps to reduce plastic in our daily lives, such as using reusable bags and containers, avoiding single-use plastics, and supporting businesses that prioritise sustainability, ultimately we need serious system change. Governments and corporations must provide alternatives to single-use materials by investing in reuse systems that make it easy for everyone to reduce plastic use. We also need strong legislation that controls plastic production and holds polluters accountable for their impact on the climate.

A strong Global Plastics Treaty – currently being negotiated by UN member states – has the opportunity to put climate first. Unlike the weak Paris Agreement, it could include legally-binding plastic production caps that would result in a huge drop in fossil fuel emissions.

What is the waste trade? Your questions answered

by Seema on 28/08/2024 2 comments

When you put your trash in the bin, do you really know where it goes?

In this post we’re exploring the waste trade, a widespread, yet little-known practice that moves mountains of trash around the globe.

What is the global waste trade?

The waste trade is the exchange of waste materials between countries. Various types of waste get exported and imported, including hazardous, non-hazardous, recyclable, and non-recyclable waste.

What countries are involved in the waste trade?

Many countries take part but the direction of trade is mainly one way. Waste is exported from wealthy developed countries to low- and middle-income nations. The primary destinations for waste exports are countries in Southeast Asia, Africa and Latin America. Central Asia and Eastern Europe are other common destinations.

Waste is exported and imported by both government agencies and private companies.

Why is waste traded internationally?

Most countries in the Global North produce more waste than they can deal with. Overpackaging and overconsumption are the norm. For example, the USA represents 4% of the global population but generates 12% of global municipal waste. And then there is industrial waste, which is many, many times greater.

Environmental regulations in these countries are usually strict and the costs of recycling or disposal are high. Exporting waste avoids these inconveniences, while taking advantage of the low labour costs and much weaker regulations overseas. This effectively outsources the burden of waste management to the recipient country.

How much waste gets traded?

It is difficult to get exact numbers on the amount of waste traded globally in any year. However, it is estimated to be in the 100s of millions of tonnes, with significant volumes of hazardous, electronic, and plastic waste being moved across borders.

Why do countries agree to import waste?

While some, correctly sorted, materials – scrap metals, for example – might have value, the main reason why countries accept waste imports is because they have little choice. Global inequalities mean developing countries rarely have the economic power or influence to turn down these containers, especially if they are dependent on the exporting nations for trade, loans or investment. This situation has led the waste trade to be viewed as a form of colonialism, as it mirrors historical patterns of exploitation, pollution and human rights violations.

It is estimated that 15 – 30% of waste shipments are illegal. Containers are often mislabelled (e.g. as “recyclables”, “paper” or “commodities” when they are nothing of the sort) or sent to unauthorised facilities. Bribes are used to get past officials. Interpol has expressed concern about the rise of organised criminal gangs working in the plastic waste trade – and the lack of resources to investigate them.

What happens to the waste?

Whether imported legally or illegally and regardless of the intentions of the exporter, the majority of imported waste is mismanaged. Some common scenarios include:

  • Illegal dumping: waste is disposed of in unauthorised areas, such as rivers, forests or even inside villages. Waste from UK supermarkets was found dumped in communities in Myanmar and Malaysia. Tonnes of toxic incinerator ash from America were rejected by several countries, before some was smuggled into Haiti for unlawful disposal and the rest thrown in the ocean.
  • Unsafe recycling: waste is processed in low-tech, often illegal, recycling facilities, by workers with few rights or safety protections. Illegal recycling centres in Malaysia were found processing German waste.
  • Incineration: waste is either openly burned, often near people’s homes, sent to cement kilns, or sold as fuel.

How does the waste trade affect recipient countries?

Environmental harm

Economic harm

  • The influx of foreign waste overwhelms local waste management systems. Countries that barely have capacity to deal with their domestic recycling now have to deal with thousands of tonnes of additional trash.
  • The influx of waste also lowers market prices for recyclable materials. This leaves local waste pickers, most of whom already work in precarious conditions, further impoverished.
  • Significant public funds are needed to clean up illegally dumped waste, as well as deal with the long-term health and environmental consequences.

Social and health impacts

  • Entire communities find themselves living next to other people’s waste and unwittingly exposed to toxic chemicals.
  • Marginalised groups, including children, are often forced into sorting imported waste. They lack legal protections and face serious health risks.
  • Mismanaged plastic waste can worsen environmental disasters such as flooding, increasing the risk of disease outbreaks.

Examples: 

How does the waste trade affect exporting countries?

The waste trade is the dirty secret of high-income countries.

Most of their citizens have no idea that the waste they dutifully put in the bin marked “recycling” is then sent overseas and often ends up dumped or burned. Countries like Germany, the United Kingdom and Japan are repeatedly praised for their “good waste management”, yet they were among the top plastic waste exporters in 2023.

This lack of public awareness has serious consequences.

Firstly, it gives people the false impression that their waste is being managed efficiently, so nothing needs to change. If everything is being “recycled”, why bother to change patterns of consumption? Companies feel no pressure to produce less waste, nor to invest in local waste management.

Secondly, it perpetuates another dangerous myth – that the Global South cannot handle its waste and is largely responsible for the plastic pollution crisis. This narrative neglects to point out that much of the “mismanaged waste” originates from producers in the Global North.

Exporting countries need to be open about and be held accountable for the waste they ship overseas.

What regulations are there to manage the waste trade?

The Basel Convention exists to control the transboundary movement of explosive, flammable, toxic, or corrosive waste and its disposal.

Signatories have agreed to:

  • Seek explicit permission from the recipient country (prior informed consent, or PIC) before exporting their hazardous waste.
  • Reduce the generation of hazardous waste.
  • Restrict the movement of hazardous waste.
  • Implement procedures and standards for the safe handling and disposal of hazardous waste.

While these measures have improved the situation, many developing countries feel they do not go far enough.

They would prefer to see a complete ban on hazardous waste exports, including hard-to-recycle plastic. The EU has agreed to this, recently banning the export of any waste to non-OECD countries from the end of 2026.

Can recipient countries do anything about the waste trade?

Recipient nations are increasingly taking a stand against the dumping of foreign waste within their borders:

But more regional collaboration, for example within ASEAN countries, is needed to develop a stronger position; and more resources are needed to investigate and stop trafficking.

How can we stop the waste trade?

No country wants to be a dumping ground for others’ trash.

To stop the waste trade definitively, countries need to take responsibility for their own waste. If it can’t be managed locally, it should not be produced or allowed on the market.

Exports of plastic and other hazardous waste from high-income to low and middle-income countries should be completely banned, following the lead of the EU.

For this ban to be effective, it will need to be supported by:

  • a reduction in plastic production;
  • robust, society-wide reuse systems; and
  • more efficient sorting, management and monitoring of waste.

Without such measures, the illegal trade in waste will only increase.

As individuals, we can make others aware of the practice of shipping waste overseas and end the “out of sight, out of mind” mentality. We can also promote zero waste lifestyles and systems to reduce the amount of waste that needs to be managed in the first place.

Negotiators for the new Global Plastics Treaty are also attempting to address all of these issues. Trash Hero is advocating for the inclusion of strong and effective measures to stop the waste trade and solve other issues caused by plastic production. Join us by signing this petition.

Are we eating plastic?

by Lydia on 24/07/2024 No comments

“Every week you consume a credit card’s worth of plastic.” You may have seen this claim on social media, but is it an urban myth or reality? We’re looking at why it might well be true.

How does plastic get into our food?

Modern-day food packaging is made almost exclusively from plastic – cling wrap, styrofoam boxes, and sachets are just a few examples. As plastic is used the surface breaks up into tiny particles. These are classified by their size. Microplastics are tiny fragments less than 5mm in length (roughly the size of a piece of rice). Even smaller, and invisible to the naked eye, are nanoplastics. These measure 100 nanometers (0.0001mm) or less. To visualise the difference, if a large piece of microplastic were the size of a football, a “large” nanoplastic would be the size of a sesame seed. For the purposes of this article, we’ll call all these fragments “microplastics”. 

Simply opening plastic packaging releases millions of microplastics into the atmosphere and our food.

Certain environments speed up the deterioration of plastic, meaning it releases even more particles. These include heat, such as from a microwave, and fat, grease and acidity from food. Direct contact with food is part of the reason microplastics end up on our plates, but they’re also found in products that haven’t been wrapped in plastic. So how do they get there? 

  • Environment: Microplastics contaminate soil and water. Plants absorb these, or they are ingested by livestock, passing into our fruit, vegetables and dairy products. 
  • Airborne microplastics: Plastic production, use, recycling and incineration release microplastics into the atmosphere, which are then inhaled by animals in the food chain.
  • Agriculture: Water containing microplastics is used for irrigation. Plastic mulch used to suppress weeds is ploughed into the soil where plants and vegetables grow. Even fertilisers are encapsulated in plastic
  • Processing: High temperatures during food processing can increase leaching from plastic equipment. Contact with vinyl gloves worn by food handlers, plastic tubing in processing machines, and the conveyor belt can contribute to the plastic in our meals. 

So one way or another, most of our food and drink contains some level of microplastic. Eating plastic raises serious concerns. But why is this? 

Chemicals in plastic

Up to 50% of plastic, by weight, is chemical additives. These are used to change how plastic behaves – for example making it flexible, hard, heat resistant, or stretchy – or to give it different colours or shine. A staggering 16,325 different chemicals have to date been identified, but the actual number is likely close to 100,000! You’ve probably heard of some already: 

  • Bisphenol A (BPA) hardens plastic
  • Phthalates make plastic soft and flexible
  • Flame retardants make plastic more resistant to heat

A significant portion (26%) of these additives are known hazardous chemicals. These chemicals are linked to issues like reproductive problems, breathing difficulties, increased risk of cancer and behavioural changes

An even larger chunk, 66%, are a mystery – scientists don’t know enough about them to say what their effects could be. Under current regulations, companies are not required to share full information about the ingredients in their plastic packaging. And many of the chemicals present are not even intentionally added – they are by-products of reactions between other additives. 

This is one of the issues with recycled plastic. Melting down and mixing different types of plastic to make a new material creates a complex “cocktail” of unknown chemicals, further complicating our understanding of the health risks.

A large body of independent research shows our constant exposure to the known chemicals in plastic, even at low levels, could pose a serious risk over time. However, the cumulative nature of microplastic exposure makes it difficult to identify the exact chemicals causing health issues. This lack of clarity is an issue for regulators. 

What regulations are there to protect us?

Some regulations are in place to limit harmful chemicals, but these vary depending on location and the specific types of plastic. The current approach relies on risk-based assessment. This means chemicals can be used freely with limited safety information and need to be proven hazardous before they are banned. This can take up to 20 years! It also allows for “regrettable substitution”, where companies can replace a banned chemical with a structurally similar one with a different name. A prime example is Bisphenol A (BPA). It was commonly found in reusable plastic water bottles until it became restricted due to safety concerns. It’s been replaced with other bisphenols, like BPS or BPF which are likely just as harmful.

Chemicals used in consumer goods and packaging should instead follow the precautionary principle. This says chemicals need to be proven safe before they can be used. With this approach, when there is not enough data to establish safety, we assume there may be risks. 

Negotiations for a global plastics treaty are well underway. Microplastics and chemical migration are high on the agenda. Scientists and activists are pushing for greater transparency in chemical use and a global shift towards the precautionary principle. The plastics industry is resisting, claiming the need for “trade secrets”, and saying a risk-based approach is enough.
