El Sobrante Landfill: Corona, CA


El Sobrante Landfill in Corona, CA, is One of the Largest and Most Advanced Waste Facilities in the United States.

El Sobrante Landfill in Corona, California, stands out as one of the country’s largest and most advanced waste management facilities. Serving communities, businesses, and industries across Southern California, the landfill delivers both environmental benefits and economic advantages.

A key feature of El Sobrante Landfill is its gas-to-energy project, which effectively converts methane, a byproduct of waste decomposition and potent greenhouse gas, into clean electricity. This process involves a network of pipes and wells that capture methane, directing it to a 14.4 MW power plant, which is enough to power tens of thousands of homes and businesses in the area. This project reduces greenhouse gas emissions and generates revenue for the landfill and the county.

In addition to its gas-to-energy project, El Sobrante Landfill boasts a leachate management system. This system treats and recycles liquid waste draining from the landfill, safeguarding groundwater and surface water from contamination. Contaminants are removed through a dedicated leachate treatment plant, and the treated leachate is then reused for dust control and irrigation at the landfill, saving water and reducing costs.

El Sobrante Landfill is a model of how waste can be managed and utilized efficiently and innovatively.
