NEWMOA undertakes a periodic analysis of the interstate flow of municipal solid waste (MSW) among the Northeast states. The purpose of this effort is to improve the quality of the data and ensure that state agencies have as much information as possible to monitor trends in waste diversion, disposal, and interstate flow in the region. NEWMOA established a Solid Waste Metrics Workgroup that focuses on conducting this analysis. They have prepared the following reports:

Municipal Solid Waste (MSW) Interstate Flow in 2018 [PDF], September 2021.

Municipal Solid Waste (MSW) Interstate Flow in 2014 [PDF], November 2017.
