11 Best Eco-Friendly Trash Bags: Compostable, Biodegradable

Are there biodegradable trash bags? For the average environmentally-conscious consumer, trash bags made from biodegradable plant-based materials seem like a sound choice, but there’s more to them than you think. Not all eco-friendly trash bags are as green as people believe them to be.

In this article, we discuss how eco-friendly trash bags work, the decomposition process, and their overall impact on the environment.

We also whittled down the 12 best eco-friendly trash bags in the market so you can rest assured that your purchase won’t put a dent in the environment.

Are eco-friendly trash bags really good for the environment?

For earth-lovers who are truly conscious about their impact on Mother Nature, the eco-friendliness of trash bags has long been a matter of debate.

Here’s what you need to know about them.

Living a zero-waste lifestyle is better.

Those truly devoted to saving the earth do not need a trash bag. They regularly compost food, refuse nonrecyclables, and donate unwanted items.

The fact that you need a trash bag is already doing the earth a disservice.

Of course, for some people, making a vow to stop producing garbage is extremely difficult or next to impossible.

At some point in our lives, most of us are still going to produce some waste, and this is where biodegradable and compostable garbage bags come in. Being ‘greenish’ is still a lot better than being not green after all.

Most trash bags don’t decompose in landfills.

A vast majority of the biodegradable and compostable trash bags available today only decompose in specific circumstances.

The conditions present in a landfill are unfortunately not enough for most garbage bags to decompose, making them no better than plastic at saving the environment.

However, several industrial composting facilities are being developed around the world whereby compostable trash bags will be much more efficient than traditional landfills.

An example of a commercial composting facility takes food scraps from household and restaurant kitchen wasste and converts the gas byproduct into renewable natural gas.

Compostable vs Biodegradable Trash Bags vs Degradable

The term ‘biodegradable’, ‘compostable’, and degradable, are often used interchangeably when used to describe trash bags, but they are three completely different things.

All of them, however, are designed to break down in specific environments.

Here’s everything you need to know about them.

Degradable trash bags

These types of plastic trash bags are crafted with a slew of chemicals and heavy metals that cause the material to break down over time when exposed to heat and sunlight.

When degradable bags are released into the environment, they break down into thousands of tiny plastic pieces that are toxic to animals.

These broken pieces are more challenging to remove from the environment than single plastic bags.

Biodegradable trash bags

Biodegradable eco-friendly trash bags are similar to degradable bags in that they contain components that help break down the material into tiny pieces.

Instead of chemicals and heavy metals, however, biodegradable bags contain microorganisms that break down the plastic.

While biodegradable garbage bags are a ‘greener’ option than degradable bags because of their more organic component, they still break down into smaller pieces of plastic that contaminate the environment.

Compostable trash bags

Made of natural plant starch, compostable trash bags do not produce toxic materials when breaking down.

With the help of water, carbon dioxide, and biomass, compostable eco-friendly trash bags decompose exceptionally in a composting system.

If you decide to throw your compostable bag in the general waste bin, it will not compost well in a landfill environment.

So which trash bag is ultimately better?

While we all should all be staunch advocates of living a zero-waste lifestyle, compostable trash bags are the better choice, but only if you absolutely must.

This is followed by biodegradable trash bags, and then degradable trash bags.

Which garbage bags are biodegradable?

Biodegradable materials are any of a number of materials that can biodegrade, or decompose naturally. The biodegrade process often requires the input of certain nutrients, moisture, light, and/or oxygen. What makes bioplastics biodegradable is that they will break down in both aerobic (high oxygen) environments like compost heaps as well as anaerobic (low oxygen) environments like the natural processes within the ground.

How long does it take a biodegradable trash bag to decompose?

When stored under microbe-rich circumstances, biodegradable trash bags can break down within several months to several years and are biocompatible. Comparatively, traditional containers take hundreds of years and are completely decomposing.

Are biodegradable trash bags better than plastic bags?

The biodegradable plastic bag market represents a more environmentally friendly solution whose cellulose is more efficient in breaking down into materials. This offers a better alternative to traditional plastic bags as they can decompose at a much faster rate.

Why are biodegradable trash bags bad?

A biodegradable trash bag is bad because bioplastics, instead of being biodegraded in a landfill, they’re potentially blown into the atmosphere and ingested by wildlife. The best alternative and most environmentally friendly option are compostable trash bags.
