What do I do with empty chemical containers?

A container is considered empty and not an RCRA hazardous waste if you can pour or scrape out contents by conventional methods unless it has contained a highly toxic P listed chemical. Containers with P listed residues must be labeled with a hazardous waste label reading “Container contaminated with ______” (state name of highly toxic residue) and submit a waste pick up request. Non-p-listed chemical containers may be reused for collecting a waste that is compatible with the original contents or if it has not contained a p listed chemical. If the empty container cannot be reused mark the container with the words “EMPTY” and remove or mark out any hazardous symbols then place in the solid waste receptacles. Containers include plastic or glass bottles, pipette tips, microfuge tubes, and other items used to transfer chemicals.
