Compostable vs. Biodegradable Trash Bags: Which Ones to Buy?

What Does Biodegradable Bags Actually Mean?

Wikipedia defines Biodegradable bags are bags that are capable of being decomposed into innocuous products by bacteria or other living organisms (such as microorganisms).

What is Compostable Bags?

Compostable products are all biodegradable, but they are specifically intended for a composting environment. Unlike standard plastic bags and even some biodegradable plastic bags, compostable bags are made of vegetable matter, such as corn or potato starch. Under normal circumstances, the product should breakdown in around 90–180 days resulting in an environment-friendly bioproduct that nourishes the soil.

Many companies use biodegradable packaging for products or produce organic biodegradable products, but the items may not be as biodegradable as customers think. To make matters more confusing, many items are labeled as "compostable."Compostable bags need to be carried out in a specific composting environment, so is it worth it?

Now there are fully biodegradable plastic bags on the market, like degradable bags, fully biodegradable are often still plastic bags that have microorganisms added to break down the plastic.

Finding the perfect fully biodegradable trash bags has proved to be the hardest. Even if you find great bags, how do you know that the manufacturing process wasn't doubly as harmful to the planet? How do you do all the research to find the best ones?

In my opinion, if we don't support green companies, the industry will never grow. We have to start somewhere, and that somewhere for me is trash bags.

Sealong Biobased has worked hard to create a trash bag that's healthy for the planet.
