The difference between biodegradable vs compostable dog poo bags
The proliferation of "eco-friendly" pet products has made choosing a dog waste bag a surprisingly complex ethical decision. Consumers are frequently presented with options labeled "biodegradable" and "compostable," terms that are often used interchangeably in marketing but hold vastly different meanings in environmental science. Understanding this core distinction is essential, as the label dictates the bag’s actual fate once discarded.
The term "biodegradable" is fundamentally vague and frequently exploited for greenwashing. It simply means a material will, at some point, break down due to biological agents. However, this process provides no guaranteed timeline, which could span years or even centuries. Crucially, many so-called biodegradable bags are merely traditional plastics blended with additives (often termed oxo-biodegradable) designed to accelerate fragmentation. When disposed of in a typical, oxygen-starved landfill, these bags rarely disappear completely. Instead, they primarily disintegrate into tiny, persistent fragments known as microplastics, which pose a significant threat by contaminating water, soil, and the food chain. Relying on the unqualified "biodegradable" label offers minimal environmental assurance.
By contrast, "compostable" is a regulated, verifiable guarantee. For a dog waste bag to earn certification—such as the European EN 13432 standard—it must meet strict criteria. This includes a mandate that the bag disintegrates and biodegrades into non-toxic, natural elements (water, carbon dioxide, and biomass) within a specific and short timeframe, typically six months, under a designated composting environment. Compostable bags are primarily manufactured from plant-based polymers like cornstarch or flax and must leave behind no toxic residue or discernible plastic fragments. This standard rigorously specifies the required conditions—be it industrial or home composting—making it a reliable indicator of full degradation.
Using Margopop are compostable bags. Made from Cornstarch, PBAT, and PLA, they’re strong, leak-proof, and fully compostable. With flat-top and tie-handle options and boxes of 18, 36, or 72 rolls, you’ll always have the right supply for every walk.
