Improving Landfill Methane Emissions Estimates with a Field-Validated Model: CALMIM


Categories: , .

Product Description

This course focuses on CALMIM [CAlifornia Landfill Methane Inventory Model], a process-based, field-validated, user-friendly model for landfill methane (CH4) emissions.  Originally developed for California, now improved and field-validated internationally at >25 sites, this course will emphasize the “why” and “how” of this approach, including a tutorial for users. This course will emphasize the importance of seasonal climatic effects on CH4 oxidation and emissions.

Upon completion of this course, attendees will:

  • Understand and be able to describe the limitations and lack of field validation for existing models (IPCC, LANDGEM), as well as recognize the need for a new site-specific model
  • Understand and discuss the major drivers for emissions included in CALMIM: thickness and physical properties of cover materials, climate, impact of gas recovery system
  • Demonstrate the application of CALMIM to specific sites, including inputs & outputs
  • Apply “default” CALMIM applications for annual greenhouse gas (GHG) inventory reporting
  • Discuss and give examples for several “customized” CALMIM applications including:
    • “What if?” modeling to guide selection of cover materials to minimize emissions at a specific global location
    • Guidance for scheduling field measurement campaigns to capture seasonal variability
    • Development of an annual framework for emissions with and without oxidation at specific sites
    • Systematic examination of emissions along broad latitudinal gradients and under future climate change scenarios

Presenter Bio

Dr. Jean Bogner has more than 35 years of experience and extensive publications related to field and laboratory research on landfill gas generation, emissions & oxidation, recovery & utilization. She was a research professor in the Dept. of Earth & Environmental Sciences at the University of Illinois at Chicago (UIC) from 2008-2014 and became Research Professor Emerita in 2014. Prior to joining UIC, she was the president of a landfill gas consultancy, Landfills +, Inc. From 1976-96, she worked at Argonne National Laboratory on landfill gas generation, recovery, and emissions, including some of the first commercial landfill gas recovery projects, as well as on mined land reclamation & water quality, remediation of contaminated sites, and radioactive waste disposal. In her earlier career (1969-75), she worked in groundwater geology for the Hydrogeology Section of the Illinois State Geological Survey and on deep tunnel and subway projects for Chicago engineering consultancies.

From 2004-2007, she was the Coordinating Lead Author for the chapter on Waste Management for the IPCC (Intergovernmental Panel on Climate Change) 4th Assessment Report, Working Group III: Mitigation of Climate Change, 2007. The IPCC was the co-recipient of the 2007 Nobel Peace Prize with former U.S. Vice President Albert Gore. She has also participated in numerous international workshops, committees, symposia, and review meetings, mentored U.S. and international students, and conducted field research in many countries. Other selected honors include the “Lifetime” award for waste research [Sardinia ‘13], SWANA Lawrence Lecturer 2008, and Lifetime Achievement Award SWANA Landfill Gas Division 2005.
