There are 540 bags in this pack, so you're set for at least 6 months of twice-daily dog walking fun. The EU deems these bags compostable, too, meaning they will disintegrate on your garden sharpish.

These cornstarch bags claim to be 100% biodegradable, and of course, we must take this with a pinch of salt, but they are made from natural cornstarch, which should compost well. 

They have long pull ties, making them easy to seal with no smells or mess, and a clever box design that makes grabbing one quick and easy. There are 160 bags in this box, so they may not last as long as other packs on our list, but they are thick and sturdy.

The beautifully-illustrated branding of these bags needn't fool you, they also do what they promise; to biodegrade even in low temperatures. They're chemical-free, too, with a low carbon footprint. 

These spacious bags are made from EU certified compostable cornstarch, made stretchy and strong with biodegradable polymers. The cardboard box they come in is also made from recycled fibre, so they tick many an eco box.

These bags are an exceptional choice because they have a large capacity and flat bottoms, meaning they are well-suited to owners of larger pets. They are also unscented, so no unnatural fragrances are used.

Made from biodegradable cornstarch, they will naturally break down on your compost heap in around 12-weeks, which is certified as planet-friendly according to EU regulations. This 8-pack should last well!

These extra-thick dog poop disposal bags are brilliant because not only are they superbly strong, they're also fashioned from cornstarch, vegetable oils and biodegradable polymers.

This roll of 270 large-sized bags should last you a good few months, and though the bags don't have pull ties, they are unscented, meaning there will be no unpleasant chemicals entering your compost. 

Packaged in recyclable cardboard, this roll of 120 dog poop bags is excellent value for money and helps the planet too. The bags are lavender-scented, which helps to mask unpleasant smells effectively. 

These dog poop bags cannot be composted at home – instead, they will take up to one year to biodegrade. Although this is a much shorter time than plastic, they are probably not the most eco-friendly option on our list compared to other plant-based options. 

This multi-pack of biodegradable bags contains 270 compostable sacks with which it's extra easy to scoop up your dog's waste. They aren't scented but do have handy long ties meaning no mess.

As these bags have not (or not yet!) been certified as compostable according to strict EU guidelines, there's a chance they may not biodegrade within a 12-week time frame, so they aren't our first choice for protecting the soil or the planet.
