Background
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. To increase the amount of acceptable organic waste, the Division has installed a food depackager system to preprocess material to be used in the in-vessel digester. The food depackager system separates the usable organic portion of in-coming waste from inorganic packaging/waste which prevents the waste from being utilized directly in the in-vessel digester.
The construction project was initially advertised for bidding on June 29, 2018 and on July 27, 2018 two bids were received. Both bids had multiple errors in the proposals and had to be rejected. The construction project was re-advertised for bidding on August 1, 2018 and on August 17, 2018 two bids were received. On August 29, 2018 the project was awarded to Titus Maintenance and Installation Services. Construction ended on December 10, 2020. The proposed date of the Notice of Completion is February 23, 2021. |
