Sustainable Environment
Reason for Recommended Action/Background
These actions will allow the Department to start the construction of the Electrical Control System to run the In-Vessel Digester Facility.

California has a statewide goal to divert 75 percent of waste from the landfill by 2020. In February 2007, the California Department of Resources Recycling and Recovery (CalRecycle) adopted Strategic Directive (SD) 6.1, which calls for a 50 percent reduction in the amount of organics being disposed in the landfills by 2020. Organic waste makes up approximately one third of the 35 million tons of waste that is currently landfilled in California. To aid in meeting the state wide 75 percent goal, Assembly Bill 1826 was passed in September 2014 requiring businesses, including state agencies, which generate certain amounts of organic waste per week to have organic waste recycling programs on or after April 1, 2016. To meet these goals, the landfill has implemented a three-part strategy: having an organic waste transfer facility, an anaerobic composter facility, and construct an in-vessel digester (liquid digester).
The Division of Integrated Waste Management has designed an in-vessel digester (liquid digester) to further divert organic waste from being disposed of in the landfill and surface impoundments. The in-vessel digester will also generate methane for electricity from the diverted organic waste. The construction of the In-Vessel Digester – Electrical Control System is needed to fully operate the In-Vessel Digester facility.  Construction is anticipated to begin in Winter 2021 and be complete in Winter 2022.
Other parts of the In-Vessel Digester facility have been completed or are currently under construction. To fully run the facility, the Electrical Control System will also need to be constructed.
Collaborations (including Board advisory groups and external partner agencies)
County Counsel has approved the agreement as to form.
