Compost Right

Some things should never go in Green Carts

Contamination is when the wrong items are put into the carts. Some of the problems include:

  • Expensive repairs to composting equipment damaged by explosive materials like batteries
  • Garbage items slows down operations as materials have to be screened out and taken to the landfill.
  • Plastic and biodegradable bags breaking into small pieces that are very difficult to remove.
Putting the wrong things in your Green Cart also makes the composting process more costly and inefficient to produce finished compost.

Find out where and how to dispose of your everyday items. Visit What Goes Where. To learn how to use your blue cart the right way, see our Recycle Right page.

Do not put these items into any of your carts

Take old batteries (cell phones, laptops, cameras, lithium ion, non-chargeable) to a participating retailer for proper recycling.
Household hazardous waste like propane tanks need to be disposed of safety at a designated fire hall or landfill.

Prepare your composting

Prepare food and yard waste items properly for your green cart. This ensures the finished compost is of the highest quality and free of plastics.
