About Us

Who we are

Zanker Road Resource Management Ltd. 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. In 1998, Zanker expanded operations by permitting an adjacent landfill site as a construction and demolition (C&D) debris processing facility. These two facilities process more than 2,000 tons of mixed debris per day.

Z-Best Composting Facility

Z-Best Composting Facility in Gilroy was constructed in 1997 to produce compost from yard trimmings. Currently Z-Best receives up to 1,000 tons per day of yard trimmings, which are processed into compost and sold to Salinas Valley farmers for use on crops. In addition, 350 tons per day of municipal solid waste and food waste is processed at Z-Best for sale to the local landscaping industry.

GreenWaste Recovery Inc.

In conjunction with its sister company, GreenWaste Recovery Inc., Zanker operates a state-of-the-art Materials Recovery Facility in San Jose, capable of sorting and recovering 83 percent of commercial and household waste. The 83 percent diversion rate translates into huge volumes of material that are not buried in a landfill, but rather given new life as usable products.

Zero Waste Energy Development

Zero Waste Energy Development Company, a joint venture between GreenWaste Recovery and Zanker Road Resource Management has proposed a 150,000-ton per year dry fermentation anaerobic digestion (AD) facility that will produce biogas containing methane and a compost product that would be marketed in to landscape applications. The proposed facility will be permitted and operational by the end of 2010.
