The Altamont Landfill opened the first industrial Covered Aerated Static Pile (CASP) composting facility in Alameda County, providing in-county processing of up to 500 tons per day of residential green waste co-collected with food waste.
Composting
CASP Facts
Over the course of a year, 156,000 tons of material will be diverted from Altamont Landfill and processed into an estimated 346,7000 cubic yards of finished compost.
Modeled after the successful composting system at our sister facility at the Redwood Landfill in Marin County, the CASP features 45 computer-controlled, aerated bays on a 10-acre paved pad, capable of composting 200 tons of material each over the approximate 21-day cycle. Stormwater and contact water are contained in a dedicated lined pond and an additional 30 acres is set aside for compost curing. The state-of-the-art facility took more than five years to permit and build at the cost of $15 million.
Dedicated to producing the highest quality compost, the Altamont facility will add Alameda County Compost to the WM EarthCare product line of locally sourced and produced, 100% recycled compost and mulch. Like Redwood’s Homegrown Compost, we will pursue listings from the US Composting Council Seal of Testing Assurance, Organic Materials Review Institute and California Department of Food and Agriculture nutrient label for WM EarthCare Alameda County Compost.
