This full project build out is ultimately capable of processing 300,000 tons per year of organic waste-to-energy. The facility was constructed in four Phases and generates biogas from organic waste materials such as green yard waste, mixed green waste (trail mix), food waste, and FOG.

Phase 1 work provided a complete functioning plant, while the balance of the phases provided for the expansion of processed volumes of organic waste-to-energy. Phase 1 included a 45,000 SF pre-engineered Receiving Building where the green waste is ground and mixed to a suitable size for anaerobic digestion. The green waste is then transported via conveyor system to four (4) each (98’Lx23’Wx25’H) concrete anaerobic digesters that are equipped with slow moving agitators to create a homogenous blend of feedstock digesting 76,000 tons/year.

The anaerobic digesters produce methane gas (approx. 430 SCFM) which is piped to a concrete round post digester (62’ dia. x 32’ H) that has a flexible double membrane gas storage dome roof. The post digester gas is then cleaned up through a gas conditioning system to produce a natural gas pipeline quality equivalent. The product gas is then compressed and is used for natural gas trash disposal trucks and/or fuel for powering
generators to provide electrical power for the plant. The total capabilities of this project approaches 4 megawatts.

(Lyles) has teamed with Anaergia, a global leader in both the agricultural and the waste sectors to deliver the Victor Valley Wastewater Reclamation Authority (VVWRA) Biomethane Project. This renewable energy project is designed to collect and upgrade biogas from existing digesters within the VVWRA and meet the specifications of SW Gas Rule 22. Sludge and food waste will be digested to generate biogas that will be conditioned and upgraded into pipeline quality natural gas and sold through the local utility agency.

This project utilizes Anaergia’s Omnivore high solids approach to the anaerobic digestion of wastewater and nutrient recovery with robust thickening systems to triple the capacity of the existing wastewater digesters. The VVWRA Biomethane project reduces approximately 6,000 metric tons of methane (2 million CO2 tons equivalent) per year, which otherwise would have been flared or released into the atmosphere.

The VVWRA facility leverages the existing wastewater treatment plant to meet organic waste recycling requirements, expanding yields of renewable energy, while partnering with publicly owned infrastructure.

��Ʒ���þø���һ������. has teamed with Anaergia, a global leader in both the agricultural and the waste sectors to deliver this one of a kind, progressive design-build project. The Rialto Bioenergy Facility (“RBF”) addresses two pressing waste management issues in Southern California: food waste diversion from landfills, and biosolids management. The RBF is designed to convert 700 tons per day of food waste, and 300 tons per day of biosolids into renewable natural gas, renewable electricity, and class A fertilizer, making it the largest project of its kind in North America.

The design includes a Receiving and Pre-Processing Area in which both Wet Fraction (food waste) and Biosolids Cake (dewatered sludge) are received and stored separately inside two Storage Silos. The cake from the Cake Silo is fed directly to the dryer, and the wet fraction is sent through a series of cyclones (dynamic and hydro) to remove any remaining in-organics before being sent to anaerobic digesters. The wet fraction is biologically broken down within the digesters and methane (biogas) is released. The solid waste is pumped to a centrifuge to be dewatered before being transferred to the dryer. The dried product undergoes pyrolysis to allow for the generation of a liquid centrate that is treated at the new WTP in an effort to capture and reuse as part of the overall project, and the pyrolyzed char will be shipped off-site via truck and sold as fertilizer. The biogas generated from this process is then converted to a RNG (Renewable Natural Gas) through a series of gas conditioning equipment and used as two forms of renewable energy. The RNG is used as fuel to operate CHP engines that generate up to 3 MW of electricity that is upgraded and pressurized then sold to Southern California Edison to be injected into the SoCal Gas pipeline.
