This Report is an update of the 2011 Earth Engineering Center (EEC) Report to the American Chemistry Council (ACC) which was based on U.S. 2008 data and quantified the energy and economic value of municipal solid wastes (MSW) and non-recycled plastics (NRP). The study presented in this Report is based on 2011 data, compiled in the EEC 2013 Survey of Waste Management in the U.S. and on MSW characterization studies conducted by several states.
