What is the most effective and environmentally responsible way to manage amalgam waste in a dental office to minimize mercury contamination?

Recycle through an EPA-approved amalgam recycling program
Capture with the dental suction system only
Use a chair-side trap and discard as regular waste
Use an in-line amalgam separator only

Show answer and explanation

Correct answer: A. Recycle through an EPA-approved amalgam recycling program

Amalgam recycling through EPA-approved (and state-certified) amalgam recycling programs is the most effective and legally compliant method to prevent mercury contamination of the environment. In 2017, the EPA promulgated the Dental Effluent Guidelines (40 CFR Part 441), requiring dental offices to use ISO 11143-compliant amalgam separators with ≥95% removal efficiency and to send collected amalgam waste to recycling programs (not dispose in regular trash, drain, or infectious waste). Recycling recovers the mercury and silver components for reuse. Chair-side traps and suction systems capture only a portion of the waste and do not constitute final disposal. The captured amalgam must still be recycled.
