The Best Biodegradable Trash Bags For a Healthier World

Biodegradable and compostable bags are the next big step to take to help create a better and healthier world because plastics are still one of the biggest culprits of pollution. With the best biodegradable trash bags, you can help keep landfills and other regions clear from plastic bags and microplastics because these bags will naturally decompose into nutrients that help nourish the soil.

In this guide, we take a look at eco-friendly trash bags that are just as functional as your everyday plastic bag, and we share useful tips to help you choose quality bags so you can get the best value for your money.

What Is the Difference Between Biodegradable and Compostable Bags?

Before we dive in and review the best eco-friendly bags, it is important to understand the difference between biodegradable and compostable bags.

These bags are usually made from one of two bioplastics. Polylactic acid is an edible type of bioplastic that is usually made from sugars in plant matter like corn starch, cassava, and sugarcane. Polyhydroxyalkanoate is genetically engineered and made from microorganisms from organic materials.

Bioplastics are better alternatives than traditional plastic, but they still have an effect on the environment since the manufacturing processes of these products usually result in greenhouse gas emissions. However, the gasses produced by these manufacturing processes have a much smaller impact on the environment compared to the manufacturing processes of traditional plastic bags, especially considering how long normal plastic takes to break down.

The main difference between biodegradable bags and compostable bags is their breakdown method. Here is a quick look at how these two eco-friendly bag types are designed to decompose.

Biodegradable trash bags

Biodegradable plastic bags are a type of bag that can be broken down by microorganisms into carbon dioxide and compost under the right conditions.

Compostable plastic bags

These bags are designed to break down in a compost site at the same rate as organic plant matter. The breakdown process is also achieved by microorganisms and these compounds are broken down into water, carbon dioxide, and other compounds. This type of bag will leave no toxic residue behind.

Are All Biodegradable Bags Environmentally Safe?

Buyers should be wary of trash bags that might contain small quantities of recycled plastics. Some bags are considered eco-friendly because they contain 100% recycled plastic instead of newly manufactured plastics.

These recycled plastic bags are designed to reduce pollution rates but they still include plastic to help strengthen the bag and enhance its durability. These types of bags still need to be recycled since they pose a risk to the environment and may result in microplastic pollution.

The best eco trash bags are the ones that are compostable and biodegradable since these bags are manufactured from organic, renewable matter, and they eventually fully decompose and leave no toxins or microplastics behind.

Recycled plastic takes just as long as conventional plastic to naturally break down. The typical breakdown period of polyethylene plastic bags ranges from 500 to 1000 years in landfill conditions. The most environmentally-safe decision you can make is to stick to compostable trash bags.

Now that you know the main differences between biodegradable bag types, it is time for you to start shopping for the right bag to use at home. In this review, we compare the five highest quality and most popular eco-friendly trash bags that you can get for home or industrial use.
