What is the proper method for disposing of unusable pesticides or empty containers in Illinois?

• A. Burn containers in open air; discard with regular trash
• B. Return to supplier or approved disposal facility; triple rinse containers; puncture if required; keep records; never dispose of pesticides via sewer or storm drains
• C. Dump in the nearest drain; leave the labels on
• D. Store indefinitely on site; never dispose

Answer: (B)

Proper disposal of unusable pesticides and empty containers follows a controlled waste-pesticide management process to protect people and the environment. The best approach is to return the waste to the supplier or to an approved disposal facility, triple rinse the containers to remove any remaining residues, puncture the containers if required, and keep records of the disposal. Never dispose of pesticides through sewer or storm drains.

This path is correct because it ensures the waste is handled by licensed facilities under regulatory guidelines, reduces remaining residue in containers, prevents the container from being reused or leaking, and provides a traceable record of disposal. It also avoids practices that endanger water, air, and soil quality, such as open-air burning, dumping into drains, or simply storing indefinitely.
