ReSEAcled Poo Bags

Box of 16 rolls / 240 bags with handles


You'll always need poo bags...

Why not subscribe so you never run out and also pay a little less?

The only dog poo bags that empower you to actively stop ocean-bound plastic with every use.

  • Award winning eco-friendly dog poo bags designed for general waste and dog poo bins. Bags are 24cm tall (excluding handles) by 22cm wide when opened.

  • World's first certified Plastic Negative poo bag by rePurpose Global.
    Each bag funds the collection and recycling of one bottle's worth of ocean-bound plastic. This equates to removing 5 times more plastic from nature than used in the poo bags, giving them (and you!) a Plastic Negative footprint.

  • Made from 50% recycled HDPE plastic (e.g. old shampoo and milk bottles) and 25% natural oyster shell waste, made in a factory certified to the Global Recycled Standard.

  • Waste-based poo bags are better for our planet.
    Stop creating new waste by choosing poo bags that re-use it! Reusing waste has clear evidence-based benefits, such as cutting carbon emissions, reducing energy use, conserving scarce resources and minimising waste sent to landfill and incineration. 

  • Putting a sustainable waste stream to better use.
    Oysters are widely considered a sustainable food source, but millions of tonnes of waste shells are landfilled every year. Adding waste shells to poo bags reduces the use of fossil fuels and improves the sustainability of the aquaculture industry. Processing the shells also provides a livelihood for local communities.

  • Guided by science, not market trends.
    Compostable and biodegradable poo bags do not reliably breakdown as claimed, still contribute to microplastics and can be just as bad as normal plastic - especially if not disposed of correctly. Learn more below.

The poo bag world is filled with greenwashing. We’re here to set the record straight.

Problems with Compostable & Biodegradable Poo Bags
Problems with their creation:
  1. Not “plant-based”. Whilst often marketed as such, they still contain 50 - 80% polybutylene adipate terephthalate (PBAT) a biodegradable polymer made of fossil fuels. Only a mere 15 - 30% of the poo bag consist of cornstarch / plant material.
  2. Still a plastic. While branded as “plastic-free”, these bags are in truth a type of plastic themselves – they are a “bioplastic”. They have the polymeric chemical structure of plastic. Any plant material used in its making has been chemically changed with other polymers added as above.
  3. Plant-based plastic currently relies on food crops (corn / sugarcane) so directly competes with human food production and demands large amounts of land, energy and water. These scarce resources should be used to feed people of the world who are already battling starvation.
  4. Some life cycle analyses indicate that plant-based plastic is the same, if not worse, than normal plastic, in terms of contributing to climate change, air pollution, ecotoxicity and energy use. This is mainly due to the industrial farming practices used to grow these crops, which undermines its potential sustainability.

Problems with their disposal:
  1. Not biodegrading or ending up where they should. We lack the infrastructure to collect and industrially compost dog poo and less than 5% of people compost at home. This means these bags go to landfill or incineration. In landfill, they do not breakdown properly and produce methane, a potent greenhouse gas. In incineration, they can produce more carcinogens than some types of normal plastic.
  2. Contributes to plastic pollution. These bags give people the false impression that they will quickly "break down" in any natural environment. But many studies show that biodegradable and compostable plastics often fail to biodegrade in real world environments, remaining intact for years before fragmenting into microplastics.
  3. Increases littering. Misleading messaging as above lead to many thinking the bags will breakdown if left in the environment, which they don't.
  4. New research shows 60% of certified home compostable bags don't reliably biodegrade in home compost, fragmenting into microplastics that could contaminate food plants.
  5. There's a high level of customer confusion surrounding the terms biodegradable, degradable and compostable bags. Meaning the wrong bags may end up in the wrong place, where they will not breakdown.

Until we have sustainable compostable poo bags that reliably biodegrade and the infrastructure to actually compost them, we don't believe compostable (or biodegradable) poo bags can be considered 'eco-friendly'. This is in line with expert advice (as also discussed on BBC Radio 4 podcast 'Sliced Bread').

Frequently Asked Questions

Are these bags biodegradable or compostable?

No. Research shows that even 'biodegradable' and 'compostable' plastic does not biodegrade in the real world and contributes to microplastics. Nothing properly biodegrades in landfill either, which is sadly where most poo bags end up! Or they often go to incineration, rendering biodegradability irrelevant.

Nonetheless, since our bags are made from waste that was already destined to go to landfill, you're helping reduce the amount of new waste going there - nice one.

Where are they made?


We tried to make these locally but were unable to find a suitable factory that could make poo bags to our specifications and at an acceptable cost.

As of 2024, we have not found any poo bags that are made in the UK.

To help mitigate this impact, we ship our poo bags by sea and never fly anything in. The manufacturer we partner with also has had a SMETA 4-pillar audit, that assesses labour standards, health & safety, environmental assessments and business ethics.

Where should these bags be disposed?

General waste at home or dog poo bins.

While they are technically recyclable, they cannot be recycled due to their contents!

Should I buy these if I compost my dog's poo?

No, if you compost your dog's poo you are better off without any poo bags or using certified home compostable poo bags.

How big are the bags?

Each poo bag measures approximately 24cm from top to bottom (36cm from top of handles to bottom of bag) and when opened they measure approximately 22cm wide.

How thick are these bags?

They are 15 microns thick.

How many bags in a roll or box?

There are 15 bags on a roll and 16 rolls in a box (240 bags in total).

What Can We Improve On?

1. Recycled material percentage.

The bags currently use 25% virgin plastic. We have experimented with 100% recycled content but unfortunately, strength and quality were compromised. We are actively working towards 100% recycled content and hope to have this available by the end of 2024.

However, these current bags are still better than compostable and biodegradable bags that include 50-80% virgin fossil fuel based polymers (PBAT), or non-recycled bags that use 100% virgin material.

2. Where it is made.

ReSEAcled Poo Bags are made in China. We would ideally want to make them locally but have been unable to find a suitable factory that could make them to our specifications and at an acceptable cost to the end consumer.

As of 2024, we have not found any poo bags that are made in the UK.

To help mitigate this impact, we ship our poo bags by sea and never fly anything in. The manufacturer we partner with also has had a SMETA 4-pillar audit, that assesses labour standards, health & safety, environmental assessments and business ethics.


While not perfect, ReSEAcled Poo Bags are the least harmful option for our planet when accounting for the entire life cycle of a poo bag.

Our Journey from Compostable to ReSEAcled Poo Bags

Soon after starting our jobs as vets, we created Pet Impact and vowed to improve poo bag sustainability. Little did we know this would change the path of our lives forever…

Young and naïve, we simply followed what other brands were doing and began selling compostable “cornstarch” poo bags. Like others, we believed these were made from plants and would biodegrade regardless of where they end up, leaving no trace... How wrong we were!

After selling our compostable poo bags for a month, we had a moment of realisation. Like us, almost everyone disposes of compostable poo bags in general waste and poo bins. But these bags are not designed to go there...

This was the spark that pushed us to ask more questions. We read countless studies, spoke to plastic experts, emailed local councils and worked with sustainability consultants from The Rubbish Project to determine if these poo bags are as eco-friendly as claimed.

We were shocked to find out that biodegradable and compostable poo bags are as problematic as conventional plastic ones and may create more problems than they solve.

First, we learned that they need very specific compost environments to successfully biodegrade. But as there are no industrial composting facilities in the UK that accept dog waste, we must place them in a compost bin at home – something less than 5% of dog owners do.

This means compostable poo bags are going to landfill or incineration, rendering their biodegradability irrelevant..

Landfill lacks the right conditions for biodegradation (i.e. no oxygen or living microorganisms), so compostable poo bags persist for potentially hundreds of years, with the added problem of releasing methane, a potent greenhouse gas!

We then learned that compostable poo bags are a type of plastic themselves (bioplastics). Without the correct conditions for biodegradation in real-world environments, they release microplastics over time.

We then found that “plant-based” compostable poo bags have an extremely large environmental footprint, potentially larger than normal plastic. They still rely heavily on fossil fuels and are made with up to 80% PBAT, a biodegradable plastic made from petrochemicals! Most only contain 15-30% cornstarch despite being marketed otherwise. Using cornstarch isn’t great either – it competes with human food production and demands huge amounts of water, land, chemicals, and GMOs to produce.

We decided to stop selling our compostable poo bags and followed expert advice to create ReSEAcled Poo Bags from existing waste.

Considering biodegradability is irrelevant in incineration or landfill, what matters most is what the poo bags are made of. Recycling has consistently been shown to be the best case scenario in terms of sustainability, reducing plastic pollution, using less energy and emitting fewer emissions. It also avoids the many pitfalls of plant-based plastic, such as deforestation, biodiversity loss and competition with human food production.

We then went one step further and got ReSEAcled Poo Bags certified Plastic Negative meaning they remove five times more plastic from nature than they introduce.

While they may not be perfect, through learning from our mistakes and years of ongoing research, we're confident they are the best solution we have right now.

Transform a daily act to have a profound impact.

8 million pieces of plastic end up in the ocean, every day.

Recycling and reducing are vital, but they're not enough.

To tackle the plastic crisis, we must incentivize the removal of existing hard-to-recycle, low value plastic waste from the environment.

ReSEAcled Poo Bags do just that, making an immediate impact on plastic pollution while empowering marginalised waste workers in India - where plastic waste currently poses a significant environmental threat.

Their unique Plastic Negative certification with rePurpose Global, means that for every unit of plastic used in our poo bags, we remove five times that amount of plastic from nature, or the equivalent of one bottle's worth of plastic!

Once a source of pollution, our poo bags have transformed from being part of the problem to being a key part of the plastic pollution solution. Join us in using poo bags as a force for good!

Why ReSEAcled Poo Bags?

You reduce waste sent to landfill and incineration.

Instead of making new plastic from virgin materials, you re-use waste that was already destined for landfill and incineration, meaning less new waste is sent there.

You have a smaller carbon footprint.

Recycling plastic requires significantly less energy and produces lower carbon emissions during production.

You use sustainable renewable content with a positive social impact.

Every year, millions of tonnes of oyster shells are thrown away. You give it a second life!

Unlike plant-based raw materials, using oyster shell waste is widely considered sustainable as it's vastly less resource intensive, doesn't require GMOs, doesn't compete with human food production and doesn't contribute to deforestation.

Processing these shells also provides a livelihood for local communities.

You reduce plastic pollution & support communities most impacted by it.

Through its Plastic Negative certification, your ReSEAcled Poo Bags fund the ethical removal of low value, hard-to-recycle plastic before it enters the ocean.

Therefore, you're not just disposing of waste responsibly; you're actively contributing to a movement that reduces plastic pollution at source while supporting communities most impacted by it by providing safe, stable, and dignified work.

The Oyster Shell Difference
  • The shell of an oyster represents more than 70% of its total weight, meaning every year, processing oysters for food leaves behind millions of tons of waste shells, most of which are landfilled.
  • No additional demand is placed on oyster farming for ReSEAcled Poo Bags. Only existing waste shells are used.
  • The calcite in the shells can be added to plastic to reduce its fossil fuel content, without compromising quality or functionality. The mining of limestone for calcite is typically environmentally destructive but converting waste shells to calcite is comparatively simple and requires less energy. It is also quickly renewable.
  • Sustainability - Oyster farming is widely considered sustainable due to their rapid growth and need for few resources. In fact, they can actually have a net positive environmental impact due to their ability to clean the water of pollutants and sequester carbon dioxide.
  • A responsible supply chain - Oysters are mostly sourced from coastal areas in Asia. Working in the oyster trade is a full time occupation for many residents. Like many local industries, individual households have the opportunity to make a living by providing a small part of the whole process - everyone has a way to earn money without one large entity controlling their employment.

    The ‘shucking’ is normally done by older female family members, but the industry involves the construction and renewal of the oyster bed infrastructure and preparing and transporting both the oyster meat and the shell. The requirements of the industry are diverse and it provides work for men and women of all ages.

Very happy with these poo bags and pleased to be supporting a small business with a good environmental cause. One small criticism is that the sticky labels on the rolls are so sticky that they can be difficult to remove for fear of tearing the bags. Not a big problem though.

Hi, thank you for the review and feedback! That's really useful to know about the labels - we've now changed them to hopefully be less sticky and easier to remove. If you find they're still an issue, drop us a message and we'll continue working on it :)

Pleasantly Surprised

The ReSEAcled poo bags are great. A good size, shape and a nice colour. For some reason, they make picking up easier, with much less liklihood of spillage than many other bags.
They are also tough and are good at masking smells.


I love these poo bags. They're thicker than a lot of other brands on the market and the handles make it super easy to carry around until I can properly dispose. I love that they are genuinely eco-friendly and that the brand is very transparent about their product. I will definitely be buying more!

Mark C.
Brilliantly researched poo bags

Been buying these since their launch and have done a bit more research (out of interest!) since then on "eco-friendly" poo bags, and am so pleased these exist. Good eco friendly solution and great poo bags that do the job!


Exactly what I have been looking for. After much research I believe recycled poo bags are the best way to support the enivronment at the moment and these are great.
Thank you
