Using compostable trash bags will help you in your efforts to compost food. Food scraps don’t break down in landfills, so by composting them, you’re actually helping the environment. Compostable bags are designed to break down quickly in a compost.
As someone who has been using curbside compost pickup, I know that there are a lot of things to consider when it comes to choosing the right bag. Characteristics like size, thickness, and durability all come into play, as does the type of compostable material the bag is made from.
If you’re new to composting or just looking to upgrade your current composting setup, the best compostable trash bags come from brands like UNNI, Repurpose, SuperBio, and Envision EcoSafe-6400.

I have a small kitchen and don’t produce much waste – is a compostable bag worth it?
Compostable bags can be a great way to reduce your carbon footprint, even if you don’t produce a lot of waste. They’re also handy for collecting food waste, which can help keep your kitchen clean and reduce the smell of rotting food.
what’s the difference between compostable bags and biodegradable bags?
Compostable bags are next-level bags. They break down completely in a composting environment. Composting is a more environmentally friendly option, as it doesn’t produce the methane gas that landfills do. Read more about compostable vs. biodegradable materials here.
can I put compostable bags in my regular trash can?
No, it’s vital that you put compostable bags in a compost bin (that you can also make yourself). If you put them in your regular trash can, they’ll just end up in the landfill and won’t break down.
