Ever since the advancement of technology, environmental awareness has become a major concern in our society.
People have started to realize the significance of fostering a sustainable environment.
This has increased the popularity of eco-friendly products, including trash bags.
Compostable and biodegradable trash bags are two of the most common types available in the market.
While these terms are often used interchangeably, they are different.
This article will discuss the difference between compostable and biodegradable trash bags to understand which is better for the environment.
Understanding Composting and Biodegradation
Composting breaks down organic matter, such as food scraps and leaves, into a nutrient-rich soil amendment.
Composting is a great way to reduce your waste and give your plants a boost of nutrients.
On the other hand, biodegradation means that bacteria or other organisms can break down the material over time.
Biodegradable materials, such as paper and food scraps, will eventually decompose into compost.
Composting and Biodegradation – Key Benefits
Composting has environmental benefits as it reduces landfill waste and greenhouse gas emissions.
It also enriches the soil, conserves water, and promotes plant growth.
Likewise, opting for biodegradable materials not only reduces waste but they often require less energy and resources to produce than their non-biodegradable counterparts.
Composting and Biodegradation – Drawbacks
One potential drawback of composting is that it can attract pests, such as rats and flies. You may consider using a covered compost bin if you live in an area with many pests.
You should also keep your compost pile away from your home. Some people find the smell of rotting food scraps to be unpleasant.
Conversely, biodegradable materials may break down slower than you would like.
For example, paper products may decompose in your home compost bin for several months.
If you are looking for a material that will break down quickly, you may want to consider using compostable materials instead.
What Are Compostable Trash Bags?
Compostable trash bags are made from materials that can easily decompose at a specific temperature and in specific environmental conditions.
They are designed to break down into organic matter, which can be used as a nutrient-rich fertilizer for plants.
These trash bags also follow a different standard than biodegradable bags regarding the material used and the certification process.
Consumer-compostable bags can be put in a compostable bin for further treatment, where they break down into nutrient-rich soil.
Compostable trash bags are made from natural materials, such as cornstarch, vegetable oils, or plant cellulose.
They require specific composting conditions to biodegrade, such as high temperature and humidity.

What Are Biodegradable Trash Bags?
Biodegradable trash bags are made from materials that can break down into smaller pieces over time, usually within a year.
The material gets broken down by bacteria, fungi, and other microorganisms.
Biodegradable bags break down into smaller plastic particles that remain in the environment. The particles can cause harm to the environment, especially marine life.
These trash bags can be made from conventional plastic mixed with additives that promote quick breakdown.
However, they dissolve at a slower rate than compostable bags.
This makes them a better solution for storing trash that won’t decompose immediately, like food products that contain animal fats and oils.
Note that some biodegradable bags are not certified by a third-party organization, and these bags might not compost in modern landfills.
Difference Between Compostable and Biodegradable Trash Bags
The most significant difference between the two types of bags is the following:
Compostable bags break down into nutrient-rich soil. In comparison, biodegradable bags break down into water, carbon dioxide, and biomass in landfills.
Biodegradable bags can include plastics with additives that cause them to break down faster, creating microplastic pollution.
Nevertheless, compostable bags also require specific environments that can compost them correctly.
Their validity depends on the underlying state regulations that determine the minimum standard.
The bags have to meet a particular list of criteria to receive certification, including:
- A certain breakdown timeline
- Material composition standard
- The material must not harm the environment.
Compostable vs. Biodegradable Trash Bags – Which Is Better?
The answer to this question depends on your needs and preferences. If you are looking for a material that will break down quickly, you may want to use compostable materials.
However, if you are concerned about pests or odors, you may want to use biodegradable materials instead.
In general, compostable trash bags are better for the environment than biodegradable trash bags.
These bags are made of natural materials and break into organic matter, a nutrient-rich fertilizer for plants.
On the other hand, biodegradable bags release toxic substances when breaking down that can be harmful to soil, water, and organisms.
Both biodegradable and compostable trash bags are environment-friendly alternatives to regular plastic bags, but it is essential to understand their nature and how each type is decomposed.
- Biodegradable bags may not compost at modern landfills, leaving them to decompose without adequate testing of the environmental impact.
- While compostable bags don’t produce any toxic material, they need to be processed correctly, like food waste, to break down without releasing methane gas.
- It is essential to check the certification of the bag in question to ensure it meets industry standards.
- It’s crucial to note that neither type of bag should go into your regular trash as it undoes any good intentions.
