Characterizing Emissions from California Biomethane Facilities
Characterizing emissions of greenhouse gases and other pollutants from a variety of waste management activities that produce biomethane.
The research team submitted a Monitoring Plan Report that summarized the relevant facility and process details, defined the conditions for which emissions monitoring will occur, and the instrumentation and measurement techniques to be used for emissions monitoring. Currently measurement of methane and criteria pollutants is in progress at the Yolo County Central Landfill, City of Davis Wastewater Treatment Plant, Napa Composting Facility, and a dairy site in Hilmar, CA. Data analysis is being conducted at a steady pace.
The Recipient will characterize emissions of GHGs and other pollutants from a variety of waste management activities that produce biomethane such as aerobic composting, anaerobic digestion, and digestate aeration systems at a landfill, processes at a wastewater treatment facility, and a dairy lagoon and anaerobic digester. This will be performed both before and after project implementation, with additional focus on potential fugitive emissions. The results will be analyzed, emissions factors will be quantified, and recommendations will be formulated for future waste management practices and research
This project's results will support initiatives such as the Short-Lived Climate Pollutant Strategy, air emission reductions, and increased safety by the establishment of a pre-project emission baseline for the diversity of common types of biomethane RNG production sites; investigate the potential for fugitive emissions at these sites; and quantify the air quality and climate pollutant impacts of biomethane project development. This research is anticipated to reduce the amount of solid waste going to landfills and will support organics diversion from landfills towards the production of value-added products.
