Understanding Biodegradability
Biodegradability is a term you’ve probably heard a lot in recent years, especially in eco-friendly discussions. But what exactly does it mean? In the simplest terms, a biodegradable substance is capable of being decomposed by bacteria or other living organisms. It’s Mother Nature’s own recycling system!
Biodegradable garbage bags are made from plant-based materials like corn starch and other renewable resources. Instead of contributing to the never-ending mountains of plastic waste, these bags break down naturally over time, returning to the environment as harmless organic matter. The decomposition process typically takes 12 to 24 months, a blink of an eye compared to the hundreds of years it takes for traditional plastic bags to break down.
How to Choose the Best Biodegradable Garbage Bag
Choosing the right biodegradable garbage bag goes beyond just picking the first product you see on the shelf. Here are a few factors you should consider:
- Size: Choose a size that fits your trash can. Bags that are too small will struggle to contain your waste, while those that are too large may lead to unnecessary wastage.
- Durability: Biodegradable doesn’t mean weak. Look for bags that are tear-resistant and capable of holding your trash without splitting at the seams.
- Thickness: A thicker bag typically translates to a stronger bag. Check the product description for information on thickness.
- Price: Like any product, you’ll want to consider the price. However, remember that investing in biodegradable bags is also investing in our planet’s future.
- Customer Reviews: Check out what other users have to say about the product. Their insights can help you make an informed decision.
Now that you know what to look for, let’s dive into our top picks for the best biodegradable garbage bags on Amazon.

Why Switch To Biodegradable Garbage Bags?
- Environmentally Friendly: Unlike traditional plastic bags, biodegradable bags are made from natural materials, which reduce carbon emissions during production. Additionally, they decompose into harmless elements, posing less harm to wildlife and ecosystems.
- Reduction in Landfill Waste: Biodegradable garbage bags decompose much faster than traditional plastic, reducing the volume of waste in landfills.
- Encourages Sustainable Practices: Using biodegradable products promotes a more sustainable lifestyle and encourages companies to develop more eco-friendly products.

How to Properly Use and Dispose of Biodegradable Garbage Bags
Now that we’ve picked the best biodegradable garbage bags, let’s learn how to use and dispose of them correctly.
- Use Quickly: Biodegradable bags start to break down when exposed to light and air, so use them within a year of purchase, and store them in a cool, dark place.
- Fill Up: Make sure you fill your bags up to avoid wasting them. An empty bag still requires energy to produce and decompose.
- Compost if Possible: If your local waste management facility allows, compost your biodegradable bags along with food scraps and other compostable materials.
Frequently Asked Questions (FAQs)
1. What are biodegradable garbage bags made of?
Biodegradable garbage bags are usually made from plant-based materials like corn starch, potato starch, or other types of renewable resources. They can also be made from PBAT (Polybutyrate Adipate Terephthalate) and PLA (Polylactic Acid), both of which are compostable polymers.
2. How long do biodegradable garbage bags take to decompose?
The decomposition time of biodegradable garbage bags can vary based on the materials they’re made from and the conditions they’re exposed to. Typically, they can decompose in the soil within approximately 12 to 24 months, far less than the hundreds of years it takes for traditional plastic bags to break down.
3. Are biodegradable garbage bags better for the environment?
Yes, biodegradable garbage bags are generally better for the environment than traditional plastic bags. They’re made from renewable resources and can decompose naturally over time, reducing the amount of plastic waste that ends up in landfills and oceans. However, they still require energy to produce and transport, so the best practice is to reduce waste overall.
4. How should I store biodegradable garbage bags?
Biodegradable garbage bags should be stored in a cool, dry place, away from sunlight and high temperatures. This is because heat and light can start the decomposition process. Using them within a year of purchase is typically recommended.
5. Are biodegradable garbage bags compostable?
Not all biodegradable garbage bags are compostable. While both biodegradable and compostable bags break down over time, compostable bags are specifically designed to decompose in composting conditions, turning into nutrient-rich compost that can benefit soil. Always check the product label to ensure you’re using the bag as intended.
6. Can biodegradable garbage bags be recycled?
No, biodegradable bags typically can’t be recycled. They’re designed to decompose rather than be recycled like traditional plastic. Mixing them with regular plastic recycling can actually contaminate the recycling process.
7. Can I use biodegradable garbage bags for food waste?
Yes, most biodegradable garbage bags can be used for food waste. They can be a great way to collect food scraps for composting. However, always check the product label or manufacturer’s guidelines first.
8. Are biodegradable garbage bags more expensive than regular plastic bags?
Generally, biodegradable garbage bags are slightly more expensive than regular plastic bags. This is due to the higher cost of producing bags from plant-based or other renewable materials. However, many consumers are willing to pay a bit more for a product that is more environmentally friendly.
9. Do biodegradable garbage bags have a smell?
Some biodegradable garbage bags are unscented, while others may have a light scent added. The smell can vary depending on the brand and the materials used. Some people prefer scented bags to help mask the smell of garbage, while others prefer unscented bags to avoid potential irritants or allergens.
10. Can biodegradable garbage bags hold liquids?
Yes, many biodegradable garbage bags are designed to be leak-proof and can hold liquids. However, as with any garbage bag, it’s best not to overfill them or put in sharp objects that could potentially puncture the bag and cause leaks.
