Landfill Emission Estimates: PIER supported research

This research, supported by the California Energy Commission's PIER program, focuses on obtaining accurate estimates of methane emissions from landfills, which are currently marked by high uncertainty. A three-year project (2007-2010) aims to analyze cover materials, develop a validated emissions model, and incorporate findings into improved methane inventory methodologies. Using two years of field data and advanced measurement techniques like laser mapping, the study will enhance understanding of landfill emissions, crucial for effective climate change mitigation strategies.

  1. Landfill Emission Estimates: PIER supported research Guido Franco Public Interest Energy Research Program California Energy Commission Climate Change Workshop California Integrated Waste Management Board May 8, 2007

  2. PIER Program • Funded by the electricity and natural gas rate-payers • Funding climate change research since 2001 • Implementing a roadmap of research developed in 2003 • Created the California Climate Change Center • Produced more than 50 PIER reports on • Climate Analysis and Modeling • Inventory Methods • Mitigation Options • Impact and Adaptation Studies • Organizes Annual Research Conferences on Climate Change

  3. PIER/CEC Landfill Methane Study • Methane emissions estimates from landfills are highly uncertain • Goals: • Obtain a better understanding of the performance of various cover materials to control methane emissions • Create a detailed landfill methane emissions model • Incorporate these results into an improved inventory methodology for landfill methane emissions • A 3-year project, from 2007-2010

  4. Project Description • Investigate the use of data collected by IWMB and air district as predictive parameters • Collect 2 years of field data, using flux chambers to obtain emission rates • Measurements taken at individual landfill cells • Methane plume mapping with lasers will be in use at one landfill to provide additional field validation (Waste Management) • Create a scientifically sound and practical “validated” model • Account for variation across landfills and climates • Account for oxidation in cover soils. This will be a key component of the model
