Renewable Natural Gas Facilities

RNG is produced by processing and cleaning biogas, high in methane, from waste streams to create pipeline-quality gas that is interchangeable with traditional natural gas. The impact on the environment of methane is greater than that of carbon dioxide, so reducing methane emissions from waste streams yields a net life-cycle greenhouse gas reduction when that methane is combusted instead of being emitted to the atmosphere or flared. The demand for renewable energy sources is increasing, leading to the evaluation the opportunity to integrate RNG into the fuel supply. Using RNG helps to divert waste streams, encourages local development, and adds sources of supply. There are also emissions benefits when the RNG is produced rather than flaring biogas. Over 17,000 potential RNG sites in the US can generate 8-12 million tons of methane equivalents annually. This equals the energy demand from 3 million homes or 2.5 billion gasoline gallons.

The Rialto Bioenergy Facility is North America's largest landfill-diverted organic waste digester facility, addressing two pressing waste management issues in Southern California: food waste diversion from landfills and biosolids management. The facility converts 700 tons per day of landfill-diverted organic waste and 300 tons per day of biosolids into renewable natural gas, renewable electricity, and Class A fertilizer.

The Rialto Bioenergy Facility serves the Southern California region as a regional organic recycling outlet with a net carbon dioxide emissions reduction of approximately 220,000 metric tons annually – equivalent to taking nearly 50,000 cars off the road.

Anaergia Group designed, built, owned, operated, and financed the facility.
