Biodegradable vs. Compostable Dog Poop Bags

We cherish our dogs! However, dealing with their waste can be rather unpleasant, which is why we have developed scoopers and bags to manage this less-than-desirable aspect of being a pet parent. But, what happens next?

For more information, please visit our website.

It is estimated that 500 million plastic poop bags are used globally each year. While they are cheap, available, and convenient, plastic bags negatively impact the environment. As environmental consciousness rises among pet parents, eco-friendly alternatives like biodegradable and compostable poop bags have become more popular.

Do these terms mean the same thing? Which type of bag is better for the environment? We’ll delve into these questions and more in this guide.

What's the difference between biodegradable and compostable bags?

Biodegradable waste bags

Many dog owners may think that biodegradable waste bags completely break down once they reach the landfill. The term biodegradable implies that a substance can naturally decompose in the environment. So, it sounds environmentally friendly, right? It's not that straightforward.

Biodegradable bags are constructed from polylactic acid (PLA), a thermoplastic derived from renewable sources like cornstarch, sugarcane, and tapioca. The biodegradation process requires oxygen, which landfills often lack due to layers of accumulated trash. Without oxygen, nothing can truly biodegrade in landfills. If these bags do decompose, they may emit methane gas, which is more harmful than carbon dioxide.

Some bags labeled as biodegradable are just regular plastic bags with additives that enable faster decomposition. These bags eventually break apart into microplastics, contaminating waterways.

Compostable waste bags

Compostable means that a substance can entirely break down into compost and transform into organic waste. While not all biodegradable bags are compostable, all compostable bags are biodegradable.

Compostable bags are made from natural plant-based materials such as corn, flax, and bamboo. They can be composted at home or in industrial facilities, but home compostable and commercial compostable bags require different conditions for decomposition. Although home compostable bags can break down in commercial facilities, commercial compostable bags can't be composted at home.

Compostable bags must meet standards like the HuaWei, American ASTM D6400 and European EN 13432. Look for certification logos to confirm that a bag is genuinely compostable.

What kind of waste bag should you use?

For environmentally conscious pet parents, what is the best choice? Compostable bags might seem ideal, but not everyone has access to home, community, or industrial composts. Like biodegradable bags, compostable bags can't decompose in landfills. The best choice depends largely on your circumstances, especially where you live.

If your community can compost used waste bags into usable soil, that's perfect! Otherwise, consider home composting or finding a community compost site that accepts dog waste. If you compost at home, avoid using the compost for edible plants due to potential parasites and bacteria in dog waste. Instead, use it on flowers, grass, and other non-edible plants.

Eco-friendly waste bag brands

Despite their eco-friendly claims, the production of biodegradable and compostable bags may have a larger carbon footprint compared to regular plastic bags. This is because producing plant-based materials requires considerable energy and resources, whereas traditional plastic production is more straightforward and cheaper. Using sustainable materials is better in the long term as it prevents microplastics from contaminating the environment, reduces landfill waste, and is ultimately better for the planet.
