In recent years, the demand for eco-friendly alternatives has led to the rise of biodegradable & compostable dog poop bags (compostable bags are a subset of biodegradable bags that biodegrade in compost environments).
On the surface, these bags appear to be a perfect solution for responsible pet owners. However, it's essential to delve deeper into the topic and understand why biodegradable dog poop bags may not be as environmentally friendly as they seem.
Let's uncover the truth behind the hype.
-
Biodegradable Isn't Always Sustainable:
While the term "biodegradable" suggests that these bags break down over time, the reality is more complex. Biodegradable dog poop bags require specific conditions, such as high heat and moisture, to decompose properly. Unfortunately, in typical landfill environments where oxygen and sunlight are scarce, these bags are mummified and behave like regular plastic, equally capable of shedding microplastics.

Landfill Limitations:
Despite their eco-friendly claims, biodegradable dog poop bags often end up in landfills due to insufficient composting infrastructure or confusion among pet owners. In landfills, biodegradable bags decompose anaerobically (without the presence of oxygen), releasing methane, a potent greenhouse gas.
Methane significantly contributes to global warming, negating the purported environmental benefits of these bags. Properly managed waste disposal systems are needed to ensure these bags end up in the right place to properly breakdown. These systems are not currently available in the U.K.
-
Lack of Standardization:
The term "biodegradable" is not regulated consistently across different jurisdictions. This lack of standardization leads to varying definitions and confusion among consumers. Some products labelled as biodegradable may only partially break down, leaving behind microplastic fragments that persist in the environment and harm wildlife. However, it has recently been shown that even bags with proper "certifications" are not breaking down properly.
What poo bag is best for the planet?
To make a truly positive impact on the environment, we need to explore alternative dog waste management solutions and look beyond "biodegradability" as a favoured "eco-friendly" feature.
While the concept of biodegradable dog poop bags may seem appealing, their environmental impact is not as straightforward as it appears. Landfill limitations, slow degradation, and the lack of standardization pose significant challenges to their effectiveness.
Experts agree that the best option as of 2025 is to make poo bags from existing waste, i.e. recycled plastic and bio-renewable waste.
This is why we created ReSEAcled Poo Bags.
Made out of repurposed waste, these award-winning poo bags directly reduce your plastic and environmental footprint by also actively funding ocean-bound plastic removal.
