Approved Compostable Bags

Plain, uncoated (no shine) paper bags and compostable bags are good ways to contain and carry food scraps to your food and yard waste cart.

Compostable bags are made from plant-based materials that break down when composted. These bags are green or very pale green. They aren't plastic or black in color.

Don't put plastic and “biodegradable” bags in your food and yard waste bin:

  • Plastic bags don't break down and will ruin the compost.
  • Bags labeled “biodegradable” usually break down into small pieces, but aren't compostable.
