Waste Minimization Prioritization Tool WMPT

Shortly after the first list of 80 chemicals targeted for voluntary PBT data gathering was complete, the EPA issued the Waste Minimization Prioritization Tool (WMPT). This was originally a software tool given away in unfinished editions by the EPA for public interest groups to assess various substances in commercial waste streams. The WMPT was designed to assess the persistence, bioaccumulation and toxicity characteristics of chemicals. The scoring system used a maximum of nine points, with three points for persistence, three points for bioaccumulation and three points for toxicity.
