The State of California has been supporting regional climate change research for more than a decade. These studies have complemented research at the national level and have been designed to inform climate policy deliberations and actions in California. This Research Catalog provides basic information about past and ongoing climate change related studies that state agencies have conducted or commissioned since the early 2000s. The purpose of this catalog is to document California’s research efforts and to facilitate the exchange of information.

  1. Air and water impacts from direct land application of un-composted green waste
    Lead Agency: Cal Recycle in collaboration with ARB
    Principal Investigator(s): Peter G. Green (UC Davis, Civil & Environmental Engineering)
    Year finished: 2015, Budget: $175,000
    Notes
    As pressure for direct land application of un-composted green waste increases, the potential air quality and water quality impacts need to be determined.


  2. Anaerobic Digester Technology Evaluation
    Lead Agency: Cal Recycle
    Principal Investigator(s): Ruihong Zhang (UC Davis)
    Year finished: 2007, Budget: $120,000
    Published/Product: http://www.calrecycle.ca.gov/Publications/default.asp?pubid=1356
    Notes
    Conducted research to analyze the rotary drum reactor (RDR) process for breaking down municipal solid waste and separating biodegradable organic material from nonorganic material when the solid waste is used as a feedstock for anaerobic digestion. Published Integration of Rotary Drum Reactor and Anaerobic Digestion Technologies for Treatment of Municipal Solid Waste. The report evaluates the rotary drum reactor in combination with anaerobic digestion to produce energy, compost, and increase waste diversion.


  3. Assessment of Landfill Gas Monitoring Well Viability and Its Effect on Greenhouse Gas Emissions
    Lead Agency: Cal Recycle
    Principal Investigator(s): Raymond H. Huff, R.E.A. (SCS Engineers, Inc)
    Year finished: 2007, Budget: $153,625
    Published/Product: http://www.calrecycle.ca.gov/publications/default.asp?pubid=1311
    Notes
    Research examines landfill gas (LFG) monitoring well functionality in California using data gathered at 20 landfills. Results used to assist the California Energy Commission in refining its GHG emission models.


  4. CalTrans Demonstration Projects, Workshops & Outreach on Compost-Based Best Management Practices
    Lead Agency: Cal Recycle in collaboration with CalTrans and Local Governments
    Principal Investigator(s): Bill Baker (Regents of the University of California Riverside)
    Year finished: 2010, Budget: $200,000
    Published/Product: http://www.ciwmb.ca.gov/Organics/Erosion/Workshops/2008/Default.htm
    Notes
    To conduct outreach to Caltrans and other governmental agencies on compost-based BMPs. These agencies have the potential to increase their compost use by hundreds of thousands of cubic yards per year for erosion control, vegetation establishment, and water filtration. This research project will encourage increased compost production that will result in the diversion of additional organic materials from landfills.


  5. Compost Best Management Practices and Benefits
    Lead Agency: Cal Recycle
    Principal Investigator(s): David M. Crohn (Regents of the University of California Riverside)
    Year finished: 2010, Budget: $150,000
    Published/Product: http://www.calrecycle.ca.gov/Publications/default.asp?pubid=1377
    Notes
    Conducted research on the benefits of compost and mulch and quantified the benefits by studying compost-based Best Management Practices (BMP) in a field demonstration setting on fire-ravaged land and also on plots simulating a post-construction site.


  6. Compost Cover at Landfills Methane Emissions Reduction Demonstration
    Lead Agency: Cal Recycle in collaboration with ARB, CEC, Local Air Districts
    Principal Investigator(s): Ramin Yazdani, P.E. (County of Yolo)
    Year finished: 2010, Budget: $100,000
    Published/Product: http://www.calrecycle.ca.gov/Publications/default.asp?pubid=1367
    Notes
    The main objective of this demonstration project was to assess the performance of the green material as biocover over an 18-month period and to link the observed performance to both material properties (e.g., thickness) and climatic conditions (e.g., temperature). Research results for fresh and aged green material in this study are compared with applicable properties and standards for compost. Numerical simulations of both gas transport and methane oxidation during various seasons were performed to compare with the field results. Aged green material performed better than fresh green material. The report is enhances the understanding of how biocovers and other factors may reduce methane emissions.


  7. Compost Emissions and Ozone Formation
    Lead Agency: Cal Recycle in collaboration with Stop Waste and private compost companies
    Principal Investigator(s): Peter G. Green (UC Davis School of Civil and Environmental Engineering)
    Year finished: ongoing, Budget: $33,000
    Published/Product: http://www.calrecycle.ca.gov/Publications/default.asp?pubid=1369
    Notes
    This project is addressing VOC emissions from composting, which is a major barrier to expanding compost production. This research is the first to identify the full range of VOC species emitted by compost piles. Such information is critical to building accurate inventories of composting-related ozone impacts. A primary objective of this project was to analyze and isolate the full range of VOCs emanating from piles. A secondary objective was to make field measurements of ozone formation from compost emissions, and to compare those values with the ozone concentrations that would be expected based on the identified VOC species and their indexed reactivity.


  8. Compost Safety Research
    Lead Agency: Cal Recycle in collaboration with California Department of Food and Agriculture; Western Institute of Food Safety and Security; University of California Cooperative Extension
    Principal Investigator(s): Michael Payne, Dvm, Phd (Regents of the University of California (UC Davis))
    Year finished: 2009, Budget: $50,000
    Notes
    For many years, rendering has served as an effective and dependable method for animal mortality disposal. For various reasons, rendering capacity in the State has significantly declined. To address the issue, the California Department of Food and Agriculture (CDFA) and CalRecycle recognize the need to evaluate alternative disposal options. One of those options is composting. Both CDFA and CalRecycle have taken the appropriate steps within their authorities to provide for the opportunity for pilot research projects to assess the safety of composting.


  9. Cost Study on Commercial Recycling
    Lead Agency: Cal Recycle
    Principal Investigator(s): Rob Hilton, Amity Lumper (HF&H Consultants, LLC Cascadia)
    Year finished: 2010, Budget: $350,000
    Published/Product: http://www.calrecycle.ca.gov/Publications/default.asp?pubid=1372
    Notes
    Cost study on commercial recycling to address potential costs and savings from increased business waste diversion in support of the Mandatory Commercial Recycling measure in AB32 Scoping Plan. This study examined the incremental costs and savings of selected business diversion programs by focusing on key material types currently disposed that have significant potential for both disposal and GHG reduction. In conjunction, the study developed an online commercial diversion tool to assist businesses in evaluating decisions regarding whether to reduce, recycle or dispose materials along with associated cost savings & ghg reductions.


  10. Evaluating End-of-Life Product Management Systems in California
    Lead Agency: Cal Recycle
    Principal Investigator(s): Heidi Sanborn (R3 Consulting Group, Inc.)
    Year finished: 2007, Budget: $59,815
    Published/Product: http://www.calrecycle.ca.gov/Publications/default.asp?pubid=1364
    Notes
    Framework for Evaluating End-of-Life Product Management Systems in California presents a framework with which to evaluate end-of-life product management systems and offers case studies on existing product management systems for difficult-to-manage products. The report also offers recommendations for product management systems for universal waste products in California.
