How Are Dog Poop Bags Actually Disposed Of?

UK Council Rules, and What PCR vs Biodegradable vs Compostable Actually Means

Short answer: almost every UK council sends bagged dog waste to general (residual) rubbish, not food or garden waste, regardless of what the bag is made from. That means a bag's "biodegradable" or "compostable" label mostly cannot do its job, because it will spend its life in landfill or an incinerator rather than a composting facility. What does matter, whatever bin it ends up in, is how much new plastic had to be made to produce the bag in the first place. That is the part post-consumer recycled (PCR) content actually changes, and it is why Shabbee's own poop bags are built around 80% PCR rather than a biodegradable claim.

Below is the detail: what UK councils actually do with dog waste, what "biodegradable", "compostable" and "PCR" each legally and practically mean, and where that leaves the choice of bag.

What Bin Does Dog Poo Actually Go In, in the UK?

In practice, a bagged, tied poop bag goes into one of three places: your household general waste bin (black, grey or green, depending on your council's colour scheme), a public litter bin, or a dedicated dog waste bin where your council still provides one. It should never go into a food waste caddy or a garden/brown bin.

That is not a style preference, it is a hygiene rule. Dog waste can carry pathogens and parasites that food and garden waste composting is not set up to handle, so councils exclude it from those streams entirely, and most household recycling collections will not take an empty poop bag either.

Some councils, including Runnymede, have gone further and phased out dedicated dog bins altogether, directing owners to use any ordinary litter bin instead. Others, such as Caerphilly, simply require owners to bag and carry waste until they reach a bin. Either way, the destination bin is the same general waste stream used for everyday litter.

Where Does That Waste Actually End Up?

Once it is in general waste, a poop bag follows the same route as the rest of your rubbish: landfill, or an Energy Recovery Facility where it is incinerated to generate electricity. Which of the two depends entirely on your council's waste contract, not on what the bag is made from.

Fareham Borough Council states plainly that street litter and dog waste are sent to the local Energy Recovery Facility, where they are incinerated along with other residual waste. Shropshire Council has said dog waste "has been treated the same as general litter since 2008" and is typically sent to landfill or incineration. Cornwall Council manages fouling separately through Public Spaces Protection Orders, but the waste itself still goes to general disposal, not to composting.

The reason none of this waste is composted or recycled is consistent everywhere you look: dog faeces can carry parasites such as Toxocara canis, plus bacteria like salmonella and faecal coliforms, and these are not reliably destroyed by the cooler, slower composting processes used for garden and food waste. As one waste and recycling resource puts it, there are currently no industrial composting facilities in the UK that accept dog waste.

Are There Any UK Exceptions?

To be fair to the "it depends" crowd: there is at least one genuine UK attempt to do something different. A district councillor in Gloucestershire, Gill Thomas, has spent 2025 running a private wormery that processes dog waste bags from a local littering hotspot, with a University of Gloucestershire trial now getting underway. It is a serious project and worth watching, but it is not a council collection scheme, it serves one location, and Thomas herself describes it as experimental rather than certified. As things stand in late 2026, we could not find a single UK council that routinely composts or anaerobically digests dog waste from public bins. Your own council's waste pages are the place to check for local detail, since practice does vary a little even where the broad pattern does not.

What Does "Biodegradable" Actually Mean?

Biodegradable means a material is capable of being broken down by microorganisms, but that process depends heavily on the right conditions: enough heat, moisture, oxygen (or the right lack of it) and time. A bag labelled biodegradable is not guaranteed to disappear quickly, or at all, outside those conditions.

That matters a lot here, because the two places most UK poop bags actually end up are the two places biodegradability is least useful. In a landfill, waste is compacted and starved of oxygen, so biodegradable materials break down slowly and anaerobically, which can release methane rather than disappearing cleanly. In an incinerator, everything is burned regardless of whether it would have biodegraded, so the label makes no practical difference at all.

This point is worth making bluntly: "biodegradable" is not a licence to leave a filled bag in the woods, a hedgerow or tied to a fence post. Open countryside gives a bag none of the consistent heat, moisture and microbial activity that biodegradation actually needs. Left out in the open, a "biodegradable" bag will not break down in any timeframe that matters. It will sit there, largely intact, behaving in practice almost exactly like an ordinary plastic bag, while also looking littered and leaching whatever is inside it into the soil. Biodegradable or not, a used poop bag always goes home with you or into a bin, never left on the ground.

What Does "Compostable" Actually Mean?

Compostable is a narrower, testable claim than biodegradable. The UK and EU standard is BS EN 13432, requiring a material to disintegrate to under 10% of fragments over 2mm within 12 weeks, and biodegrade to at least 90% within 6 months, at the industrial composting temperature of around 58°C, without harming the finished compost.

That describes industrial composting. Home composting runs cooler (closer to 20 to 30°C), and there is no official UK standard for it yet, only a Belgian "OK Compost Home" scheme some brands certify against voluntarily. So an unqualified "compostable" claim should be read as industrial, not something for the garden heap.

Either way, certification only tells you what the bag can do inside a composting facility. It says nothing about whether the bag will ever reach one, and for dog waste in the UK, it essentially never does, since no mainstream UK facility accepts dog waste for composting. A compostable poop bag is being asked to pass a test it will never actually sit for.

What Does "PCR" Actually Mean, and How Is It Different?

Post-consumer recycled (PCR) content describes what the bag is made from, not what happens to it afterwards. It is plastic that has already been used by consumers, collected, reprocessed and turned back into new material, rather than virgin plastic made fresh from oil or gas for the first time. An 80% PCR bag is 80% previously used plastic given a second life, with the remaining 20% typically needed to keep the film strong and leak-resistant enough to actually do its job.

This is a genuinely separate claim from biodegradable or compostable, not just marketing language for the same idea. The point was made officially in 2025, when HMRC confirmed that switching to compostable or biodegradable plastic packaging does not, by itself, reduce a business's UK Plastic Packaging Tax liability, because composting is "a biological treatment process rather than the use of recycled plastic." Only a genuine recycled-content threshold (30% or more) exempts packaging from the tax, whether or not that packaging is also compostable. In other words, even the government treats "will it break down" and "how much new plastic did it take to make" as two entirely different questions.

Why Shabbee Uses 80% PCR Instead of a Biodegradable Claim

Given all of the above, a biodegradable or compostable label on a UK dog poop bag is, honestly, mostly a promise the UK waste system will not let the bag keep. The bag will go into general waste with everything else, and whether it was designed to break down in a composting facility will not change what happens to it in a landfill cell or an incinerator.

What does change, no matter which bin the bag lands in, is how much new plastic had to be drilled, refined and manufactured to make it in the first place. That is the part Shabbee chose to focus on, and it is not a hollow marketing line. It is a claim chosen specifically because it matches the practical reality of how dog waste is actually disposed of in the UK: a promise that holds up in a landfill cell, in an incinerator, or in the rare case the bag does reach a composting facility, rather than one that only holds up in the one scenario (certified industrial composting of dog waste) that almost never happens here.

It is also a claim we do not expect anyone to simply take on trust. Our 80% post-consumer recycled content is certified at the point of manufacture to the Global Recycled Standard (GRS), an independent, third-party standard that traces and verifies recycled content through the supply chain, rather than being a figure we put on the packaging ourselves. That distinction matters: a "recycled" or "PCR" claim with no certification behind it cannot actually be verified by anyone, including the brand making it. We would treat any uncertified recycled-content claim, on our own products or anyone else's, with real scepticism, and we think shoppers should too.

We have never claimed our bags are biodegradable or compostable, and this is why: we would rather be straightforward about what 80% PCR actually does than lean on a label that, for this specific product, is largely disconnected from how it is actually disposed of in the UK.

Frequently Asked Questions

Can I put dog poo bags in my food or garden waste bin?

No. UK councils exclude dog waste from food and garden waste collections because of the pathogens and parasites it can carry, which standard composting does not reliably destroy. Bagged dog waste belongs in general (residual) waste or a litter or dog bin.

If a bag is biodegradable, can I leave it in the woods or a hedgerow instead of binning it?

No, and this is worth being direct about. Biodegradable only means a material is capable of breaking down under the right biological conditions, and open countryside does not reliably provide them. A biodegradable bag left on a woodland floor or in a hedgerow will not break down in any timeframe that matters. It will sit there largely intact, much like an ordinary plastic bag, while also being litter. Always take used bags home or to a bin, whatever they are made from.

Should I trust a brand's "recycled" or "PCR" claim at face value?

Not without checking what stands behind it. A recycled-content figure is only as good as its verification. Shabbee's poop bags are certified at the point of manufacture to 80% post-consumer recycled content under the Global Recycled Standard (GRS), an independent third-party standard that traces recycled content through the supply chain. A recycled-content claim with no certification behind it, from any brand, cannot actually be verified and should not be taken on trust.

Are compostable dog poo bags pointless in the UK?

For disposal purposes, largely yes, at least for now. A compostable bag only delivers its benefit inside an industrial composting facility, and no mainstream UK facility currently accepts dog waste. A compostable bag collected in the UK will almost always end up in landfill or an incinerator alongside an ordinary one.

Can I home compost my dog's poop bags myself?

Not without real care. Dog waste can carry roundworm eggs and bacteria that survive ordinary garden composting temperatures. Specialist guidance recommends hot composting at around 60°C, gloves, regular worming, and never using the resulting compost on food crops or anywhere children play. It is not a simple swap for your household bin.

Why does PCR content matter if the bag ends up in landfill or incineration anyway?

Because PCR is about what the bag is made from, not where it ends up. Every bag made with recycled plastic instead of virgin plastic is one less bag's worth of new oil and gas extracted and refined, regardless of which bin it eventually lands in. That benefit happens at the manufacturing stage, so it is not affected by the UK's dog waste collection rules at all.

Does my specific council do anything different?

It is possible, and some councils handle dog bins, litter bins and Public Spaces Protection Orders slightly differently from one another. The broad pattern (general waste, then landfill or incineration) is consistent everywhere we could check, but your own council's waste pages are the definitive source for your area.

Is Shabbee planning to switch to a biodegradable or compostable bag?

Not based on how dog waste is actually disposed of in the UK today. We would rather keep improving on a claim that holds up regardless of which bin the bag ends up in, which is why our bags are made with 80% post-consumer recycled plastic.
