Reason for Recommended Action/Background
The recommended actions will allow the Department to solicit competitive bids, expedite contract award and promptly proceed with construction of the in-vessel digester - floating cover.

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 constructing 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 – floating cover is necessary to start diverting processed food waste into the in-vessel digester that produces biogas for power generation.

It is anticipated that the construction of the in-vessel digester – floating cover would begin in September 2018, and will finish by the end of November 2018.
