5 Best Places To Buy Compostable Dog Poo Bags [Say NO to biodegradable!]

    eco friendly dog poo bags

    If you want to be a responsible, earth friendly pet owner, compostable dog poo bags are your only choice.

    This is because other seemingly eco-friendly poo bags, such as those labelled with ‘degradable’, ‘biodegradable’ and ‘eco’ still contain plastic and are not environmentally friendly.

    With roughly 9 million dogs in the UK, our furry best mates are unknowingly contributing to the single-use plastic problem.

    So, I’ve done some research into what our best options are for eco friendly dog poo bags. Read on to find the 5 best places to buy compostable poop bags, plus explanations for the other ‘green’ options and how not to get tricked.

    This post has been updated February 2022.

    The ‘options’ for eco friendly dog poo bags

    Dogs do their business all the time. Although each dog is different, your four-legged friend is likely to go for a poo anywhere between 1 and 5 times a day. That’s a lot of bags.

    My dog, Murphy, is a bit of a machine and is at the higher end of the scale. He also used to have a sensitive stomach, but switching him to grain-free ethical dog food helped out a lot.

    On the market, there appears to be three main options for more environmentally friendly dog poo bags:

    • Degradable
    • Biodegradable
    • Compostable

    However, in the world of product labelling, these three terms can mean very different things.

    Dog poo bags are prone to ‘greenwashing’ – a misleading claim about the environmental benefits of a product. The UK government are trying to crack down on this with their Green Claims Code, but it still persists.

    The labelling of a dog poo bag as degradable is very misleading. Even the term biodegradable often falls into the greenwashing category. A compostable poo bag on the other hand is a much more substantiated and evidenced claim that you can trust.

    The only real eco option is compostable poo bags.

    What’s the difference between compostable and biodegradable poo bags?

    In the UK, there is a huge difference between compostable and biodegradable.

    A compostable item, such as a poo bag or compostable carrier bag, must meet certain standards and criteria. In order to be labelled as compostable, the item must be inspected and then certified by an independent organisation. This is similar to how the labelling of organic products works. 

    With a certified compostable poo bag, both the bag and waste inside will naturally biodegrade into compost when in the right conditions. A compostable poo bag will leave no toxins and no microplastics.

    The term ‘biodegradable’ on the other hand is not regulated and doesn’t have official certifications.

    It just means that something will breakdown generally without any time scales. This is why biodegradable can be taken advantage of from a marketing perspective and used to make unfounded claims. To the average customer, seeing ‘biodegradable’ on the front of packaging makes it sound like it will be good for the environment, but in reality, this is probably not the case.

    Biodegradable bags are often made from fossil-fuel derived plastics or a type of bioplastic with a number of additives to help them breakdown.

    In the US, the Federal Trade Commission had to warn 20 manufactures of dog poo bags who were deceptively labelling their products as compostable and biodegradable.

    This is why certified compostable poo bags are your only true eco choice.

    Why are compostable poo bags the best eco choice?

    A fully compostable dog poo bag is made from natural plant-based materials.

    More often than not, compostable bags are made from a plant starch, such as corn or potato, as well as sugars and other vegetable matter. The starchy base gives the bag strength for holding the contents.

    A 100% compostable plant-based bag means it will breakdown into the very same natural materials that a plant is made from – water, carbon dioxide and organic matter.

    If any ink is used on the bag, this will have to be compostable too and will usually be water-based.

    A compostable poo bag will need to be placed in certain conditions for it to breakdown into soil-enhancing compost. This may be achieved in a home composter or it might have to be taken to an industrial composting facility. All composting environments require the right levels of heat, moisture, microbes and oxygen.

    Depending on the composting conditions, a compostable dog poo bag will take anywhere from 3 months to a year to fully break down.

    All certified compostable materials will have a logo or code to let you know how they can be disposed.

    For example, the code EN13432 means the item is only suitable for industrial composting. An OK Compost Home logo means can be put into your home compost pile. It’s not a crystal clear system but there are rules and regulations to be followed.

    A well-managed compost pile will rot away a compostable bag in 3 to 6 months. High temperatures are critical to compost heaps (a home composter can reach about 60°C), which will not only decompose the organic waste but also kill most of the bacteria and little nasties that you don’t want in there.

    Based on how much ‘organic waste’ your dog produces, you may not be able to put every single bag into your compost pile and will have to balance it out with other organic matter. This all comes down to a well-managed pile!

    FAQs on dog poo bags

    Can you compost dog poo in biodegradable bags?

    No, you can’t compost a biodegradable dog poo bag.

    The main reason is as stated above. A ‘biodegradable’ poo bag is usually made of plastic or polythene and not organic, compostable material.

    Although a compostable poo bag is naturally biodegradable, a biodegradable poo bag is not always compostable.

    What are the most eco friendly dog poo bags?

    If you’re picking up your dog’s poo in a bag, the greenest and most environmentally friendly way to do this is in a compostable dog poo bag.

    Depending on the type of compostable bag, you may be able to compost this within your home compost pile or send it to an industrial composting facility via your local council (do check your council’s website for more information).

    If you’re thinking of buying biodegradable bags, try not to give in for the greenwashing, as these are mainly plastic bags. Go green and opt for compostable poo bags instead.

    Are biodegradable dog poo bags good or bad for the environment?

    Biodegradable dog poo bags are also made from plastic. The difference with a biodegradable poo bag when compared to just a plastic or degradable one is that it contains an additive that is supposed to help the plastic break down faster. These are sometimes known as bioplastics.

    Some biodegradable plastic bags are manufactured to become oxo-degradable at the end of use. During oxo-degradation, the additive in the material starts to cut down the long chains of plastics when placed in certain conditions – namely oxygen, heat, UV light and pressure.

    Manufacturers claim that when the material starts to oxidise and degrade (the oxo part), the fragmented molecules can then be consumed by microorganisms, again given the conditions.

    A biodegradable bag will take 2-3 years to breakdown. Even then it still may be partially intact.  

    Although this may be a quicker break down period than conventional plastic, the science behind bioplastic technology isn’t fully supported as a sustainable, environmentally friendly solution. There’s also an increased likelihood of microplastics entering the system.

    Are degradable dog poo bags bad for the environment?

    Generally speaking, dog poo bags are bad for the environment.

    This is because they are made from plastic, which is made from fossil fuels and petrochemicals.

    Plastic doesn’t only have a negative environmental impact when its raw materials are being sourced, but also during the manufacturing phase and then when they’ve finished being used.

    Plastic poo bags are likely to persist in the environment for tens, maybe hundreds of years.

    Labelling a dog poo bag as ‘degradable’ is nigh on meaningless and also heavily misleading. Yes, even plastic will degrade given a few centuries but this is not beneficial for the environment.

    We also know that when plastic eventually does breakdown, microplastics are created. Microplastics cause widespread negative impacts across ecosystems and environments due to their small size and durability.

    Using a plastic dog poo bag is probably the worst option from an environmental perspective. It can’t be recycled and either finds its way to landfill or to be burned.

    Is the stick and flick dog poo method better for the environment?

    Another way that some people deal with dog poo when on a rural, countryside walk is the ‘stick and flick’ method.

    Instead of using a poo bag to pick it the waste, it is simply flicked into the undergrowth and away from any public footpaths. The aim of this is to reduce plastic waste as the dog poo will eventually decompose into the soil.

    This method is supported by a lot of people, including the Forestry Commission, but is frowned upon by some, particularly farmers and locals. This is mainly because dog poo waste can contain pathogens, which can be very harmful to livestock if eaten. Also, because dogs aren’t part of that direct ecosystem and they don’t feed from the area, their waste has a different organic composition and may disrupt systems if left in big volumes.   

    Lastly, the disproportionate number of dogs now in the UK means that if everyone did the stick and flick method, the countryside would be overwhelmed.

    I can see and understand all of these arguments.

    However, I think that when the circumstances are right – you’re in a rural spot, there aren’t lots of dog walkers around and you’re not in a farmer’s field – the stick and flick method is best for the environment.

    I would not do this in an inner city park, near a children’s play area or just walking down the street. There’s a time and a place for the stick and flick method but, when appropriate, I think it can definitely play a role.

    Wrap up on eco friendly dog poo bags

    It’s important for me to make environmentally friendly choices where I can. Buying compostable poo bags is one instance where I can make a better, more sustainable choice and reduce plastic use.

    By using a compostable poo bag, I know the bag and its contents will end up going to produce something useful – whether this is compost for soil or energy to produce electricity (how my green waste gets used by the council).

    If you’re looking for an eco-friendly dog poo bag, there’s only one choice: a compostable bag.

    If you’ve read this far, I hope I’ve been able to shed some light on the different and often confusing terms that you see on dog poo bags to help you make your own choices. Being informed is half the battle when it comes to being a little more eco-friendly!
