Opened in 1960, the Olinda Alpha Landfill is a Class III site featuring 565 total acres, of which 453 acres is permitted for refuse disposal. The landfill has enough projected capacity to serve residents and businesses until 2030. Olinda’s average disposal rate is nearly 7,000 tons per day (TPD), although it permitted up to 8,000 TPD.

Olinda was one of the first sites in the nation to construct a landfill-to-gas energy plant, powering 3,000 homes at the time. In 2012 a new plant was opened, which currently generates sufficient energy to power more than 22,000 homes. The Olinda site features various environmental protection highlights, including the use of goats for vegetation control, native vegetation protection, an on-site falconer to deter gulls and valuable groundwater monitoring wells and collection systems.

Olinda contributes to various off-site habitat restoration efforts. These include Santiago Oaks Regional Park oak tree restoration in the City of Orange and the Puente Hills Landfill Native Habitat Preservation Authority Preserve (coastal sage scrub) in the City of Whittier.

On-site, Olinda is home to ongoing site improvements and environmental controls including a radioactive waste observation program, erosion and sediment control systems, storm water drainage and collection featuring two desilting basins with two additional planned, and native vegetation protection.
