City plans biomass facility to reduce emissions and process local waste

During the recent Napa County Board of Supervisors meeting on March 25, 2025, discussions centered on the development of two significant environmental projects aimed at enhancing waste management and reducing emissions in the region.

The first project involves a biomass gasification facility and an anaerobic digestion facility located near the airport. This initiative is part of a broader effort to improve the efficiency of waste processing operations at the existing materials diversion facility. A new property has been acquired south of the current site to support a 1.5 megawatt biomass gasification facility, strategically positioned to minimize interference with flight paths. This facility aims to process woody materials that are currently being transported to landfills, thereby addressing community needs and reducing overall emissions associated with waste disposal.

The second project focuses on anaerobic digestion, which is particularly relevant in light of California's Assembly Bill 1383, mandating the collection and composting of food waste. This facility is expected to not only mitigate food waste emissions but also produce renewable fuels that could power the fleet responsible for weekly waste collection across the city and county.

Both facilities are designed to process materials already collected and stored on-site, emphasizing a commitment to sustainability and environmental responsibility. The initiatives reflect Napa County's proactive approach to waste management and its dedication to reducing carbon footprints while fulfilling community needs.

As these projects move forward, they promise to play a crucial role in enhancing the county's waste management capabilities and contributing to broader environmental goals. The Board of Supervisors will continue to monitor progress and address any challenges that may arise in the implementation of these facilities.
