Zanker Road Landfill – Site 1
The Zanker Facilities in San Jose originally began as Zanker Road Landfill. It quickly developed into a major full service, resource management, composting/recycling facility and landfill for residents and commercial businesses. This facility is divided into operational areas handling specific types of waste materials. These areas include: Demolition Debris Recycling, Asphalt Shingle Processing, Concrete Recycling and Wood Waste/Brush Recycling. The facility is also home to the Zanker Landscape Materials yard which sells all our landscape and construction products, as well as other landscape supplies.
Zanker Materials Processing Facility – Site 2
In 1999, the Zanker Material Processing Facility, ZMPF, began recycling operations. The facility is divided into several different processing areas, each capable of processing different types of waste streams.
These areas include: Sheetrock Processing Area, Soils processing area and Mixed Construction Wastes Recycling.
Demolition Debris Processing – Site 1
In 1988, Zanker Recycling has been a leader in processing mixed loads of demolition debris with a unique “float tank” and screening system that separates the soil, mixed concrete, and wood components from the mixed debris.
In 1998 we designed and constructed a complete Demolition Debris Recycling Facility that was able to process unsorted demolition debris materials at the rate of 70 tons per hour with an average of 90% diversion rate.
In 2015, Zanker designed and constructed a new demolition recycling operation that is currently processing over 80 tons per hour with an average 95% of diversion rate.
These products are than directed to other recycling operations on site or shipped directly to end product users.
Concrete Recycling – Site 1
Zanker Recycling’s concrete plant was one of the first in the nation to convert concrete debris into aggregate products suitable for foundations and road construction.
Products produced from the recycled concrete includes a 3/4″ class II base rock, utility sand, 3/8″ pea gravel and 3/4″ drain rock. These materials are sold to contractors and the general public and are available for delivery.

Wood Waste and Brush Recycling
Landscape contractors, demolition/construction contractors, and private individuals deliver wood waste and brush to Zanker Recycling. Incoming loads composed primarily of brush; tree trimmings and wood waste are directed to the wood waste stockpile area for unloading. Wood wastes separated out at the other on-site recycling plants (especially the Construction waste sorting line) are also regularly transferred to the incoming wood waste stockpile.
The wood waste is ultimately ground and then screened to create wood chips and wood fines.
The Wood Waste plant consists of an electric Peterson Pacific grinder, an electrically powered trommel screen and a series of electrically powered feed, transfer and stacking conveyors.
The wood chips (anything larger than 3/8-inch) are temporarily stockpiled on site and then hauled off-site and used primarily as co-generation fuel and secondarily as mulch for various landscaping and agricultural purposes. The wood fines (anything smaller than 3/8-inch) are also temporarily stockpiled on site and then hauled off-site and used in landscaping projects or as soil amendment.

Mixed C&D Debris Recycling Area – Site 2
Zanker Recycling also processes an extensive amount of mixed debris and debris box’s daily through a 240-foot long C&D sorting conveyor system. The system is utilized to remove a variety of materials; up to 16 products from the typical mixed waste stream.
The sorting conveyor system, which includes elevated work-stations, Nihot air separation units, disc-screens and magnets is located above large concrete storage bunkers that hold recovered materials. When the storage bunkers become full, the materials are routed for additional on-site processing, or loaded and hauled to approved recyclers. Other materials such as mattresses, are processed separately into different products. Residual materials are routed to a landfill for disposal.
Sheetrock Recycling – Site 2
Contractors and private individuals deliver sheetrock to the Zanker typically with most of the loads being clean materials. Incoming loads composed primarily of sheetrock are directed to the sheetrock stockpile area for unloading. Sheetrock that is separated out at the other on-site recycling plants is also regularly transferred to the drywall stockpile.
Asphalt Shingle Processing – Site 1
Zanker Recycling accepts and processes clean, separated loads of composite asphalt roofing shingles removed from residential homes. The company sorts and cleans the old shingles and transports them to Oakland where they are processed into dry, granular asphalt pieces known as “RAS” (recycled asphalt shingles) that is shipped to other East Bay manufacturers to make “hot mix asphalt” used to build roads throughout the region.
The plant also accepts commercial tear off and tar and gravel roofing. These materials are stockpiles and made into alternative daily cover (ADC).
