Can I bring unused paint to throw away at the landfill?
Only if the paint is solid or dried up. Latex type paints can have the lids removed and allowed to dry out. Oil type paints will not dry out. An alternative is to bind the paints by painting waste wood or cardboard then bringing the empty paint cans and painted materials. Some individuals have mixed in sawdust or kitty litter to bind the paint. The material must meet the Paint Filter Test (EPA Method 9095) – no liquids passing through a paint filter in 5 minutes.
