  • EEC|CCNY to conduct extensive study on the heating value of non-recycled plastics in municipal solid waste

    November 5, 2014

    EEC|CCNY recently finalized a proposal for a study that will determine the representative heating value of non-recycled plastics (NRP) in municipal solid waste (MSW) based on calorimetry testing.  The motivation for this study is to address the major discrepancies that exist in the literature with regards to the energy content of NRP.  Extensive calorimetry data will be collected for waste plastic samples of all resin types collected from MSW to determine the representative heating value of NRP.  Additional objectives of this study will be to determine the impact that contamination, plastic resin type, and product type (film versus rigid) have on the heating value of NRP.  This study will be sponsored by the American Chemistry Council.

  • EPA releases official statement on handling of spent baghouse filters

    October 10, 2014

    EPA recently released an official statement on the handling of spent baghouse filters at municipal waste combustor facilities.  EPA determined that combustion of spent baghouse filters at MWC facilities do not significantly impact emissions from the combustor.  EEC|CCNY attributes part of EPA’s final decision to the White Paper that EEC|CCNY and ASME-MER submitted to the EPA in January 2014 on the environmental impact of fabric filter bag incineration.  The findings of this technical investigation determined that emissions from the combustor increased by less than 0.2% when processing spent baghouse filters.  The difference in emissions was immeasurable within the analytical detection limits of the typical monitoring systems for in-stack emissions therefore it was concluded that combustion of spent baghouse filters do not significantly impact emissions of the combustor.
