How should I dispose of non-hazardous paints and empty paint cans?
Contact your town to find out if they will accept your paint cans for recycling. Dispose paint cans that are empty or have dried paint in the regular trash. Recycle all types of paint when the containers are more than 3/4 full, and the paint has not been frozen or mixed with any other paint. Dry out water-based latex paints and dispose in the regular trash. If the can has an inch or less of paint remaining, pour some kitty litter (clay type without chemical additives) or sawdust in the can, and mix until there is no free liquid. Cover the can. For larger quantities of water-based paint, half inch layers of paint can be poured into a card board box lined with plastic. Allow each successive layer to dry before adding the next.
