Sister Companies

GreenWaste is not only different from other collection and processing companies due to its high diversion rates and level of customer care, but also because of our sister companies that create a vertically integrated company structure. Our relationships with Zanker Road Resource Management Ltd. and its two facilities on Zanker Road, Z-Best Composting Facility in Gilroy and Zero Waste Energy Development Company all contribute to GreenWaste's current and future ability to maximize diversion rates, create new energy sources from renewable and further technological innovations in the world of solid waste management.


Zanker Road Resource Management Ltd.

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.
