CR&R Municipal Solid Waste to Biomethane Project
CR&R, a large waste and recycling firm will construct and operate a 50,000 ton per year facility at the Perris Material Recovery and Transfer Station in Riverside County. This facility will process mixed municipal solid waste (MSW) from the City of Los Angeles using a wet separation technology from Arrow Ecology to separate recyclable materials non-recyclable inert waste. Biodegradable materials will then be pumped into a two-stage anaerobic digestion system to produce biogas. Purac technology will clean the biogas, which will then be injected in the Sempra natural gas pipeline where it is used by Shell Energy North America for transportation fuel. The project was originally designed to produce electricity, earning a federal tax credit. However, Energy Commission funds will enable a shift in the end product to biomethane for transportation. Byproducts will include the recovery of recyclables and a compost product called digestate.
The Energy Commission is providing $4,520,501.
The project team will provide $18,166,460.
CR&R is a large waste and recycling firm serving 2.5 million customers and 40 municipalities in Southern California. CR&R has five years of operating experience using liquefied natural gas (LNG) in 100 trucks operating out of its San Juan Capistrano facility.
Arrow Ecology of Israel will provide a waste separation technology that is currently utilized in a commercial, 300 tons-per-day plant in Sydney.
Purac of Sweden is a leading global supplier of the LP-Cooab biogas upgrading technology that will be used at the biogas facility. This technology produces very high quality biomethane that fulfills all technical quality requirements for vehicle fuel or direct injection into the natural gas pipeline.
Shell Energy North America and its subsidiaries are leading providers of natural gas, power and environmental products, marketing and trading, comprehensive risk management products, and asset and supply management services.
Other project partners include Siemens, Camp Dresser McKee, and CalStart.
CR&R estimates that the project will use 50,000 tons of waste per year to produce 120,000 mmBTUS of biomethane annually. This will displace the equivalent of 865,000 gallons of diesel, enough to power 60 to 80 heavy-duty waste hauler trucks, reducing an estimated 57,740 tons of carbon dioxide between 2013 and 2020. The project will also create 100 construction jobs and eight permanent facility/operation jobs.
