Best Compostable Trash Bags In 2024.

Did you know that, in just one year, the United States alone generated a staggering 730,000 tons of plastic bags, sacks, and wraps? 

And it doesn’t stop there – approximately 300 million plastic bags find their way into the Atlantic Ocean annually. It’s alarming to think that by 2050, there could be more plastic than fish in our oceans, measured by weight. 

That’s solely because plastic can take anywhere from 20 to 500 years to decompose. So it basically keeps piling up – year after year. 

So what can we do about it? We hear you ask. We can start by replacing our overly polluting plastic bags with the best compostable trash bags on the eco market.

Big and small compostable trash bags have an extraordinary “power” that allows them to break down super fast when exposed to sunlight, moisture, and tiny microorganisms. 

How? Instead of polyethylene, our favorite compostable bin liners are crafted with sustainable materials, such as cornstarch, sugarcane, and bamboo, which are renewable resources. 

It’s a big win for the environment and a step towards a cleaner and greener future. 

However, you should keep in mind that not all compostable tall kitchen trash bags and biodegradable bags, in general, are the same. Some may require specific conditions to break down, such as industrial composting facilities, while others can break down in home compost systems or natural environments. So many sure to check each brand’s certifications before you hit “add to cart.”

Read on to find the ten best biodegradable compostable trash bags!

What are compostable trash bags?

Compostable trash bags are a fantastic eco-friendly alternative to traditional plastic bags when it comes to waste disposal. They are specially designed to break down naturally and completely, just like organic matter, when exposed to specific conditions.

When you dispose of your compostable bin liners in a composting environment, they undergo a process called composting, where they break down into nutrient-rich soil, leaving behind no harmful residues. What makes biodegradable compostable trash bags so amazing is that they contribute to the production of nutrient-rich compost, which can be used to nourish gardens, plants, and crops. 

How do compostable trash bags work?

The magic lies in the materials used to make compostable bags. They are typically crafted from renewable resources like plant-based materials or compostable polymers. These materials have the incredible ability to decompose just like organic matter when placed in a composting environment.

When you dispose of a compostable trash bag in a compost pile or facility, it is exposed to various factors such as sunlight, moisture, and microorganisms. These elements work together to initiate the decomposition process. As the bag breaks down, it transforms into nutrient-rich compost, which is essentially nature’s way of recycling and giving back to the Earth.

How long does it take for compostable trash bags to decompose?

The time it takes for biodegradable compostable trash bags to decompose can vary depending on many different factors such as the specific materials used, environmental conditions, and composting methods. Under ideal conditions, compostable bags can fully decompose within approximately 90 to 180 days.

The decomposition times can be longer in home composting systems or less-controlled environments. In a backyard compost pile, where conditions may not be as optimal, compostable bags may take a bit longer to break down, typically ranging from several months to a year or more.

Are compostable trash bags fully biodegradable

es, compostable trash bags are designed to be fully biodegradable. Unlike traditional plastic bags, which can persist in the environment for hundreds of years, compostable bags are made from organic materials that can break down naturally and return to the earth.

Will compostable trash bags actually break down in a landfill?

Biodegradable compostable trash bags have the potential to break down in a landfill, but the process is much slower and less effective compared to composting in the right conditions. 

The lack of oxygen slows down the decomposition process, and the presence of other waste materials can further hinder biodegradation. So ideally, compostable bags should be disposed of in composting systems specifically designed to facilitate their breakdowns, such as industrial composting facilities or home compost piles. 

These environments provide the necessary conditions of moisture, oxygen, and microbial activity to effectively decompose the bags and transform them into nutrient-rich compost.
