  • U.S. EPA Volume-to-Weight Conversion Factors, April 2016 (pdf)
    EPA’s 1997 report, “Measuring Recycling: A Guide for State and Local Governments”, was a guide to facilitate standardization of MSW data collection at the local level, which included volume-to-weight conversion factors for comparing recovery efforts between municipalities, regions and states. The factors are also valuable when planners work with the national recovery data presented in EPA’s sustainable materials management report series. This is an update to the volume-to-weight conversion factors.
