How to Dispose of Latex Paint at Home

  • Cans with less than 1-inch of latex paint: Dispose of directly with regular trash. Participants in Concord's Trash Program should remove the lid and place the can and lid in a cardboard box next to the trash with a trash sticker.

Whenever practical, residents should avoid using these products. Substantial quantities of leftover oil - and alkyd-based paint can be brought to the paint shed for reuse, recycling.
