CR&R is a leader in advanced fueling operations.
CR&R Environmental (CR&R), a solid waste management company serving more than 3 million customers throughout Southern California, operates one of the most advanced fueling operations of any refuse fleet in the nation. In 2017 CR&R began operating the first commercial-scale facility in California to produce renewable natural gas (RNG) for injection into the SoCalGas pipeline. Predominantly privately financed with additional financial support from the California Energy Commission, California Public Utility Commission, CalRecycle, and the South Coast Air Quality Management District, the project converts organic waste (grass clippings and food waste) to biogas at its Perris, CA, anaerobic digestion (AD) plant. This biogas is then upgraded to RNG and distributed through SoCalGas's pipeline infrastructure.
CR&R funded the installation of approximately 1.4 miles of new SoCalGas pipeline, and a utility-owned point of receipt located on CR&R's property. This marked SoCalGas’s first project to interconnect and deliver RNG into its pipeline network.
The feedstock is green waste and food waste from 23 cities. The RNG produced at CR&R fuels approximately 150 of the company's refuse trucks. Around 600 of their remaining refuse trucks run on purchased RNG. While they use the fuel exclusively in their own operations, leveraging access to SoCalGas's pipeline made sense from both a distribution and storage standpoint. This facility will have the capacity to convert 335,000 tons of organic waste into enough RNG to displace approximately 4 million gallons of diesel fuel annually. While organic waste is primarily converted into RNG, nutrient-rich solids left from the AD process will be used to make other products. These solids are currently being purchased by major soil product producers for soil enrichment.
