Zanker Recycling is a privately owned solid waste and recycling company that began operations in 1985 by developing a landfill into a full-service resource management and composting/recycling facility. Originally, the site was mandated by the City of San Jose to divert 25% of its materials into recyclable products. In 1998, Zanker expanded operations by permitting an adjacent landfill site as a construction and demolition (C&D) debris processing facility. The two Zanker facilities process more than 3,000 tons of mixed debris per day.
