We all want to do our bit for the planet, and that includes how we manage our dog’s waste. But when faced with biodegradable poop bags and compostable poop bags, which is better? What’s the difference, and which one should you choose?
Why Dog Waste Matters
Dog waste isn’t just unpleasant—it has a significant impact on the environment:
-
40 million tons – estimated annual amount of dog waste that isn’t collected globally
-
20–30% – of pollutants in waterways come from dog waste
-
2.5 million tons – amount of dog waste going to landfills each year in New Zealand
-
20% – of all landfill waste in New Zealand is plastics
-
500 years – the time it takes for a conventional plastic bag to degrade, often leaving harmful microplastics behind
Even small actions, like switching to eco-friendly poop bags, can make a difference.

Biodegradable vs Compostable – What’s the Difference?
Both biodegradable and compostable bags will break down naturally, but there are key differences:
Compostable Bags
-
💩 100% compostable
-
💩 Made from plant fibres, vegetable oils, and starch
-
💩 Break down into carbon dioxide and water at the end of their life cycle
-
💩 Ideal if you’re adding dog waste to a compost system
Biodegradable Bags
-
💩 Made with a minimum of 38% plant material
-
💩 Degrade slightly slower than compostable bags
-
💩 Still reduce environmental impact and minimize health risks from conventional plastic
