Dr. Ketan Shah of SCS Engineers will present his paper and findings at the Air and Waste Management Association, 115th ACE-22 conference from June 27-30 in San Francisco, California. Methane generation, recovery, and emissions projections for biodegradable polyester fiber used to create clothing products are growing. This clothing will eventually be disposed of in municipal solid waste (MSW) landfills in the U.S. The scope of work described in this research project includes providing the methane estimates that discuss the data, assumptions, and calculation methods used to develop the estimates.
See the full abstract of “Methane Emissions from Disposal of Biodegradable Polyester in U.S. Landfills,” and we hope you will consider attending Dr. Shah’s presentation at ACE-22.
…and as waste settles, it can have an effect on equipment,” according to Pat Sullivan of SCS Engineers in this ClimateWire article. As the U.S. EPA focuses on pushing landfill owners into cutting down on methane emissions some worry that a combination of tightening regulations and poor cost analysis might put some smaller landfills out of business.
LANDFILL EMISSIONS: Going to the dump? You might make electricity

An SCS Engineers Technical Bulletin will be released early in the week.
The U.S. Environmental Protection Agency issued limits on methane emissions from oil and gas wells that are more stringent than those it proposed last year. The final regulations released on Thursday, May 12, 2016, will add hundreds of millions in additional costs per year; at least 25 percent higher than the preliminary version published in August 2015.
EPA Administrator Gina McCarthy told reporters on a conference call that the mandates, applying immediately to new and modified wells, are a “critical first step in tackling methane emissions from existing oil and gas sources.”
Under the rule, companies must upgrade pumps and compressors while expanding the use of “green completion” technology meant to capture the surge of gas that can spring out of newly fracked wells. Such green completion techniques have been required for new and modified natural gas wells since 2015, but Thursday’s rule would broaden the requirement to oil wells too.
