As more people look for ways to live more sustainably and in a way that is better for the environment, the number of biodegradable garbage bags has exploded in recent years.

If you’re searching for a way to line your compost bins for convenient transport to a composting facility or an alternative to your standard plastic trash bag, use biodegradable garbage bags the next time.

Every year, Americans use around 100 billion plastic bags, which need nearly 12 million barrels of oil to produce. Given that 1,900,000 plastic groceries, rubbish, and other bags were recovered during the 2018 International Coastal Cleanup, it is necessary to switch to reusable grocery bags and biodegradable garbage bags.

This blog post will look at what a biodegradable garbage bag is and the eight best brands in the market. Continue reading.

What Is A Biodegradable Garbage Bag?

Biodegradable garbage bags are made from bioplastics and help trash break down more quickly in landfills.

Even though these aren’t the answer to the problem because they have some plastic in them, they’re a step in the right direction toward using the more eco-friendly product in everyday life.

To get rid of all plastic, you should choose compostable trash bags made from natural plant starch.

Our list of the best biodegradable garbage bags will help you figure out what to look for. However, before we go into the list, let’s see why it is necessary to switch from plastic trash bags to biodegradable trash bags.

Why You Should Switch To Biodegradable Garbage Bags

According to the Center for Biological Diversity, it takes a plastic bag 1,000 years to decompose in a landfill. When bags break down, they can release chemicals and tiny pieces of plastic into the environment. 

It’s hard to give up plastic completely, but we can take simple steps to help the environment by switching to products like biodegradable garbage bags.

Even though biodegradable and compostable plastics take long to break down in a landfill than in the open air, they can still be better for the environment than regular plastic bags.

Here are some reasons why you might want to switch from plastic trash bags to ones that are better for the environment:

1. Fewer Green House Emission

Because the plants that biodegradable bags are made from (corn or sugarcane) take in carbon while growing, they release less carbon dioxide over time. 

This makes up for the carbon they give off when they break down. One study found that switching to bioplastics made from corn could cut greenhouse gas emissions in the United States by up to 25%.

2. Decompose Faster

In the right conditions, biodegradable and compostable garbage bags decompose up to 1,000 times faster than regular trash bags. Biodegradable bags start to break down when they come in contact with water or organisms like bacteria and fungi. 

Compostable bags break down faster than regular bags, but they usually need a lot of heat to break down, so they should be taken to a commercial composting facility to be thrown away.

3. Don’t turn into tiny plastics

Biodegradable garbage bags completely break down. But, most importantly, they don’t break down into tiny pieces of plastic as regular bags do.

Microplastics get into our bodies and cause health problems over time, so using biodegradable bags is a much better choice.

What Materials Are Used in Biodegradable Garbage Bags?

Biodegradable plastic is made from materials that can be grown again, like crops. But unfortunately, biodegradable plastic is sometimes made from things that can no longer be recycled or trash that can no longer be recycled. 

This is different from crude oil-based plastics that break down over time. Garbage bags that break down naturally are made of bioplastics. Biopolymers make up bioplastics and break down faster than biobased plastics. 

People think biodegradable trash bags are better for the environment because plastic breaks down faster. Biodegradable trash bags are made of things that decompose into carbon dioxide, water, and biomass.

The problem with biodegradable materials is that they need to be very hot to break down. So for biodegradable materials to break down, they must be exposed to very high temperatures, which they don’t always get in a landfill. 

Unless they go to an industrial facility, this can make the biodegradable trash bags last longer than they say they will.

How to Choose a Biodegradable Garbage Bag?

Different kinds of biodegradable trash bags are made by different companies and have different features. Based on this, it’s safe to assume that not all biodegradable trash bags can break down in a reasonable amount of time.

So, if you want your switch from regular plastic bags to biodegradable bags to count, you’ll need to think about several things, such as:

a. Durability

Even though these bags break down faster than regular plastic ones, that doesn’t mean they should be weaker. 

It’s important to be efficient, and a good biodegradable trash bag should be able to carry as much weight, if not more, than a regular plastic bag.

b. Decomposition rate

The decomposition rate tells you how long it takes for trash bags from a certain company to break down. 

This is important to consider when choosing trash bags that are good for the environment. A good bag that breaks down can take anywhere from 6 months to a year.

c. Certifications

The Biodegradable Products Institute checks to see if trash bags can break down. A product with a BPI certification meets the requirements of ASTM D6400 and ASTM D6868.

Biodegradable plastic bags that come in small, recyclable packages shows that the company cares about the environment.

4. Customers review

Customer reviews are the best way to judge any product or company. How other people who care about the environment feel about the company and the biodegradable trash bag can help you make your final choice.

Now that we’ve known things to look out for when choosing biodegradable garbage bags, let’s go on to the list of best biodegradable garbage bags available in the market.
