Anaerobic Digestion
Imagine a carbon-free, ultra-low emission, locally produced, renewable transportation fuel with enough energy to power heavy-duty vehicles.
CR&R Environmental Services (CR&R) has invested in an advanced organics processing technology known as Anaerobic Digestion (AD). This technology has enabled CR&R to produce a clean Renewable Natural Gas which can then be used to power its large fleet of refuse and recycling collection vehicles. This 100% Renewable Natural Gas is being created from the organic waste that is being captured throughout CR&R’s collection network.
Our new state of the art processing facility can accept the region’s organic waste and divert this material from the local landfills where it would naturally degrade into environmentally damaging methane gas. It’s an advanced technology that moves waste and its’ associated methane emissions away from the landfill and into our vehicles in the form of a renewable natural gas; the cleanest transportation fuel available today. In addition, we will also create a high-grade compost material for farms, gardens and other agricultural facilities. The AD system is located at CR&R’s facility in Perris, California.
A digester “digests” organic waste, producing a “biogas”. State-of-the-art systems will clean up the biogas and convert it into a renewable natural gas to be used in compressed natural gas collection trucks servicing Southern California!
This proprietary process is unique to CR&R and is fully enclosed with zero untreated emissions. It has the highest energy conversion rate in the industry due to its state-of-art design and digital controls. CR&R also has the only renewable natural gas interconnect in California. This unique interconnect, in partnership with the Southern California Gas Company; allow us to distribute our Renewable Natural Gas anywhere in the State.
The digester produces zero untreated emissions in a completely closed loop system that will:
- Eliminate more than 99% of greenhouse gas emissions from vehicle operations – the equivalent of taking thousands of cars in your community off the road. (4.8 metric tons per vehicle, EPA, 2009)
- Allow communities who participate the opportunity to meet the 75% recycling rate – now a State Goal
- Utilize waste collection trucks that have the lowest emissions in California
- Provide water-saving organic fertilizer and soil products for landscape and farm use from material not converted to bio methane
- Utilize proven technology for guaranteed performance and results.
CalRecycle and CCI acknowledgment
CR&R’s anaerobic digester (AD) facility expansion project in Perris, CA is being funded in part by CalRecycle’s Organics Grant Program, a subset of California Climate Investments. CalRecycle funds paid a portion of the construction needed for the AD facility in Perris, CA. California Climate Investments (CCI) is a statewide program that puts billions of cap-and-trade dollars to work reducing greenhouse gas emissions, strengthening the economy and improving public health and the environment— particularly in disadvantaged communities. The Cap-and-Trade program also creates a financial incentive for industries to invest in clean technologies and develop innovative ways to reduce pollution.
