The Republic Services Newby Island Compost Facility is part of the Newby Island Resource Recovery Park, owned by Republic Services and located Milpitas, just north of San Jose. The facility produces Super Humus compost and Pro Chip mulch from food scraps and yard trimmings collected locally, including from the City of Alameda, Fremont, Newark, Piedmont and San Leandro in Alameda County. Super Humus compost is listed by the Organic Materials Review Institute (OMRI) and tested in the U.S. Compost Council’s Seal of Testing Assurance Program. Since 2007, the facility has increased annual compost production to 134,000 cubic yards. The compost comes back to Alameda County in commercial blends sold at landscaping supply stores and through annual compost giveaways to residents in cities where Republic Services collects organics. The company also donates compost to schools, community gardens and non-profit projects.
