Lightweight, brandable, airtight, and cheap: sachets embody plastic’s most appealing qualities. As single-serving pouches, they are touted as affordable for low-income households. Yet, the actual cost of sachets extends far beyond their price. Their short-lived life triggers serious environmental, health, and social impacts, particularly in the very communities they claim to assist.

The first record of commercially sold sachets was in the 1980s by Unilever’s India subsidiary, Hindustan Unilever Ltd (HUL). They targeted lower-income areas with small quantities of shampoo, sold in plastic pouches for just 1 rupee ($0.01). By the turn of the century, 70% of all shampoo in India sold was in sachets and companies such as Nestle SA and The Procter & Gamble Company had also jumped on the bandwagon.  A staggering 2 billion sachets containing shampoo, laundry detergent, candy and more are now sold daily. These sales amount to enough sachets per year to blanket the entire Earth’s surface.

So why did we, and 116 other organisations globally, sign a letter asking for them to be phased out?

A means to exploit the poor and undermine local culture 

In the Global South, sachets are marketed aggressively at low-income households. At first, they may appear as an economical choice for families with low weekly earnings. A closer examination of the prices per 100g or 100ml (the “unit cost”) reveals that sachet products are frequently pricier than their counterparts in bottles or larger containers. The packaging also encourages the use of more product than may be necessary, resulting in more money lost over time. The price difference becomes worse over time. A 10ml shampoo sachet is used for one wash, while a 200ml bottle enables 20+ washes with less shampoo per wash. 

The takeover of sachets has meant traditional refill systems and the use of natural packaging have been forgotten. Before they flooded the market, families would bring their containers to shops, and shopkeepers would measure out portions of items such as sugar or cooking oil catering for all sizes and needs with no environmental impact.

The epitome of throw-away culture, but where is  ‘away’?

A typical sachet has an airtight inner plastic layer that protects the product, a foil barrier against moisture and heat, and an outer flexible layer that can be printed on. An adhesive holds it all together.

This small, single-use, yet durable design creates big environmental impacts. Their light weight means they often end up in forests, rivers, and oceans. From here, animals mistake them for food and get sick or even die after consuming them. Discarded sachets also worsen flooding by clogging waterways and drains, leading to more water-borne diseases. For something that is used for seconds, they have a very long-lasting impact!  

For recyclers and waste pickers, sachets have no value. The layers of cheap materials and adhesive render them unrecyclable and expensive to manage. So there is little incentive to collect them, as nothing useful can be done with them. . Former CEO of Unilever, Paul Polman, has said: “Packaging this small and with such little value has proved impossible to collect at scale, let alone recycle. We need to get rid of harmful sachets for good”. And he is not the only one who has spoken out. Unilever’s President for Global Food and Refreshments, Hanneke Faber, branded their multilayer design as ‘evil’ due to its non-recyclability. 

Producer responsibility: a burning question

Despite this, sachets continue to be sold in areas where waste collection infrastructure is non-existent. If not ending up in nature, the fate of most sachets is either a dumpsite or, more commonly, some form of burning. This is highly toxic, being detrimental to both human health and ecosystems, as well as contributing to the climate crisis. 

Various “recycling” schemes promoted by the producers of sachets often turn out to be little more than burning them, often as fuel for barbecue stalls or laundries, where they pollute further.

In 2017, Unilever invested in “revolutionary” chemical recycling plants in Indonesia that claimed to solve the problem of sachets. Just two years later, they quietly shut down the project. This was due to the ‘logistical difficulties of sachet collection and the challenging economics around the end product.’

In 2019, Unilever announced plans to support refill systems. They planned vendor machines in the Philippines to refill containers with shampoo and conditioner. Reuters visited the sites of these refill stations and discovered that Unilever had removed them after just one month. 

So, what is the solution?

Products sold in sachets can be sold as part of a refill system, but companies are reluctant to invest in the infrastructure needed.  Sachets are cheap to produce and so make more profit.  So they continue to focus on ways to better managing waste instead of avoiding it in the first place. 

We need companies to stop pushing unproven and harmful processes such as ‘chemical recycling’ as a solution. We need them to stop allowing poor communities, our planet and climate to bear the brunt of sachets devastating costs. We need them to commit to safe and sustainable reuse and refill systems that are accessible to everyone.

“With every product sold, we’ll recover 1kg of ocean-bound plastic. Together, we can stop plastic pollution”

Have you ever seen a claim like this? We have. As a network that organises thousands of cleanups every year, Trash Hero is often approached by companies offering so-called “plastic offsetting”. We are offered cash for trash, in return for joining a “plastic credits” scheme. 

The plastic credits industry is experiencing rapid global growth, with plastic producers queuing up to be certified. With a contribution to a middleman – like Verra or Plastic Bank – they can buy themselves “plastic neutrality”, supposedly achieved by balancing a portion of their production with a collection of plastic waste. 

Trash Hero has always refused to take part in these schemes. Why? Let’s delve deeper into the concept of plastic credits and the impact they have on plastic waste.

What are plastic credits?

Plastic credits are tradable certificates that represent a specific amount of plastic waste, typically 1 metric tonne per credit. This waste has either been recycled, picked up as litter or prevented from entering the environment. It can be made up of any type of plastic and can be from any location worldwide, but is typically “ocean-bound”, meaning it was collected within 50km of a coastline. 

The credits are issued by third party brokers that manage the collection or recycling, authenticate the origin and track sales to avoid fraud. Each broker has its own set of rules, standards and pricing for credits and there is currently no regulation of the market.

The credits confirm the amount of plastic “recovered” in the buyer’s name and entitle them to claim several different things:

• Their products, made from the same quantity of plastic, are “plastic neutral”
• Their products, if the credits are for recycled material, are made from “recycled plastic” (even if actually made from virgin plastic).
• They are helping to solve the plastic pollution problem, despite continuing to produce plastic that is toxic and polluting.

This is problematic in many ways.

Permitting “business as usual”

Plastic offsetting allows companies to say they are doing something about the problem, while continuing to produce plastic. It is easier and cheaper to buy plastic credits than to implement packaging and delivery systems that would reduce their plastic output – widely recognised as the only real means of stopping pollution. 

The credits, and the marketing around them, give the false impression that something is being done about the crisis and reduce public pressure to build alternative systems.

Do they really balance?

Different types of plastics possess unique physical and chemical properties that influence their environmental impact. But with plastic credits, there is no principle of “like for like”. Can a tonne of plastic water bottles removed from an urban dumpsite really offset the production of a tonne of low-value plastic sachets that can never be recycled and might end up in the ocean? Or a fast fashion clothing line that releases microplastic fibres into the air and water during use? These decisions are in the hands of the brokers. 

What happens to the waste that is collected?

This is another issue that complicates the “offsetting” calculation. “Recovery” of plastic waste has no universal definition, and in practice has been shown to include disposal in open dumpsites and various methods of incineration – all of which have serious, long term impacts on the climate and human health. In our experience, most waste that is collected from nature is mixed, contaminated or degraded and only a small percentage can be recycled – or, more likely, downcycled. 

Even in the ideal case, plastic never ‘disappears’ when it is recovered. Clean PET bottles may be recycled once or twice at best, then must be landfilled or incinerated. It is misleading to suggest recovery of any sort can negate the impact of creating new plastic destined to meet a similar end, just a short while later.

Challenges with additionality

Additionality refers to the concept of demonstrating that the waste collected through plastic credits is in addition to what would have been collected anyway, without the credits being purchased. This is not the case if credits come from trash collected by existing waste pickers, or that is diverted from going to an existing recycling programme. However, this is nearly impossible to check or adjudicate. There is a worrying lack of independent standards, transparency and oversight in the industry.

Perpetuating waste colonialism 

Aside from the issues of calculation, plastic credits raise significant social and ethical considerations. The majority of companies participating in these schemes are large corporations located in developed countries, predominantly in the Global North. Whereas most, if not all, of the projects that collect plastic waste are based in less developed countries, primarily in the Global South.

By purchasing these credits, corporations take advantage of cheap labour costs and more lenient environmental and health and safety regulations. This dynamic perpetuates an already unfair situation. Waste workers and waste pickers in less developed countries of the Global South continue to bear the harmful consequences of handling low-value plastic waste that is often exported from developed countries in the first place.

For all of these reasons, Trash Hero will never take part in any plastic offsetting programme.The goal of our cleanups is to engage and educate the community to reduce waste, not to enable plastic producers to greenwash their image and continue creating trash for us to pick up forever.
