Amalgam Resources
Resources for Requirements, Recycling
The MDA continues to answer questions about dental amalgam recycling, including this most recent one:
Is an office required to use a certain brand or type of separator?
According to the Water Protection Program of the Missouri Department of Natural Resources, there is no requirement or endorsement for any brands of separators.
40 CFR 441.30 establishes the requirements for amalgam separators. The following is the requirement from the rule most likely applies to the question,
“Compliant with either the American National Standards Institute (ANSI) American National Standard/American Dental Association (ADA) Specification 108 for Amalgam Separators (2009) with Technical Addendum (2011) or the International Organization for Standardization (ISO) 11143 Standard (2008) or subsequent versions so long as that version requires amalgam separators to achieve at least a 95% removal efficiency.”
Further detail of the specification requirements for amalgam separators can be found in 40 CFR 441.30.
Did you know MDA has a complete page on the Dental Amalgam Rule to provide information on requirements and to answer your questions.
