RCI – Third Party Certification

Zanker Recycling is the first facility in California to receive third-party certification of its recycling rates from the Recycling Certification Institute (RCI). The RCI uses independent third-party evaluators to verify the accuracy and reliability of the recovery/recycling rates reported. Providing a rigorous set of protocols, guidelines, and tools to professionally review and certify the recovery/recycling reports of participating C&D recyclers, the Institute is intended to increase certainty and build confidence in the C&D recycling marketplace on the part of project owners, architects, the environmental community, municipalities and the public.

Every load that comes to Zanker is given a weight tag with the type of waste that was received. RCI has certified or registered seven Zanker Recycling operations in San Jose. Recycling rates for each of the operations is listed in the table below along with the types of materials that each operation processes. These diversion rates are based on the total tons of incoming materials/the total tons of waste landfilled. A separate calculation shows the recycling rate, less alternative daily cover (ADC).

The USGBC developed the new Pilot Credit Point as part of a focus on performance in its LEED rating systems. The intent of the point is to encourage a verification standard for recycling facilities, urging them to quantify waste data accurately. The point will reduce uncertainty associated with self-reported numbers, and as a result will achieve higher quality construction and demolition waste diversion.

The credit is available for pilot testing by a variety of LEED 2009 project types including: New Construction, Core and Shell, Schools, Retail, Commercial Interiors, Homes, and Existing Buildings. Visit the USGBC website at for specific details on the Pilot Credit, and on the requirements for independent third party certification. Presently, the Recycling Certification Institute’s (RCI) Certification Of Real Rates (CORR) Protocol is the only program that meets the requirements of this Pilot Credit.
