Alternative and Renewable Vehicle Fuels

The Sanitation Districts have played a significant role in reducing air emissions and developing emissions controls in our solid waste management and wastewater treatment operations. Past and ongoing projects include: processing landfill gas into compressed natural gas (CNG) for use as an alternative fuel; developing emissions control technologies for heavy-duty vehicles; converting Districts-owned transfer trucks to alternative fuel; purchasing CNG vehicles; and constructing CNG fueling facilities at various Sanitation Districts' locations.

Technologies such as as fine bubble diffusion, variable speed drives, and high-efficiency motors have allowed the Sanitation Districts to save millions of dollars in power costs.

Landfill Gas-to-Energy Facilities

Biogas, generated during the decomposition of organic material managed in landfills, is used to generate electricity. One of the first to utilize biogas as a natural resource to produce renewable energy, the Sanitation Districts' energy recovery facilities at the Calabasas and Puente Hills Landfills provide reliable and economic electrical power to help serve Southern California's increasing energy needs.

Almost 79 megawatts (MW) of electricity is generated in Sanitation Districts' wastewater and solid waste operations. In total, the Sanitation Districts produce power equivalent to the needs of about 110,000 Southern California homes. Some of the electricity is used in powering Sanitation Districts' operations; the rest is used to reduce the amount of power produced by utilities, thereby, reducing greenhouse gas emissions.
