Updated · By the RipePrice team
For eco-friendly trash bags, check what the claim actually means, whether your area can compost the bag, and whether the size fits your bin, since the right size wastes less.

Compostable, biodegradable or recycled content
Compostable: means the bag is designed to break down in a composting system.

A compostable bag only helps if your waste goes where it can be composted.

Compostable, biodegradable or recycled content
Compostable: means the bag is designed to break down in a composting system. The claim usually depends on the right conditions, such as an industrial composting facility, and on whether your area accepts compostable bags. A compostable bag in a landfill may not break down as the label implies.
Biodegradable: a vague word. The FTC's Green Guides say such claims need to be qualified, because it is not clear how long breakdown takes or where it happens.
Recycled content: means the plastic includes recycled material. The label may say how much. This is a specific claim you can check.
Certification: some compostable products carry a third-party mark, such as one from the Biodegradable Products Institute. We do not name a product as holding one.
Our angle: check your local rules first
A compostable bag only helps if your waste goes where it can be composted. Some cities accept compostable bags in green bins, some accept only paper bags, and some do not collect food waste at all. Before you buy, check your local waste service. If it does not accept compostable bags, a recycled-content bag in the right size may be the more practical choice.
Fit and strength
Match the bag size to your bin. A bag that is too big wastes material, and one that is too small slips and tears.
Check the thickness or strength rating if shown, and the drawstring or flap tie, which affects how easy it is to carry.
Compostable bags can break down faster in heat and moisture. Store them dry, and do not leave them in the bin for long periods.
Comparing prices
Divide the price by the number of bags to get the price per bag.
Compare bags of the same size and strength.
Check subscriptions and large boxes against your usual store.
Are compostable trash bags better for the environment?
Only if your area can compost them. In a landfill, a compostable bag may not break down as the label suggests. Check your local waste rules.
What does biodegradable mean on a trash bag?
It is a vague word. The FTC's Green Guides ask that biodegradable claims be qualified, since it is unclear how long breakdown takes or where it happens.
How do I choose the right size?
Match the bag to your bin so that it fits without slipping or leaving a lot of excess.
How do I compare trash bag prices?
Divide the price by the number of bags, and compare bags of the same size and strength.
