Zanker Recycling

Zanker Road Resource Management Ltd. operates four nationally recognized recycling facilities: The Zanker facilities are national leaders in construction of demolition debris diversion and composting. Through its aggressive recycling efforts, Zanker diverts more than 80 percent of waste they receive from landfilling.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. The two Zanker Facilities process more than 2,000 tons of mixed debris per day.Z-Best Composting Facility located in Gilroy was constructed in 1997 to process yard trimmings into high grade compost. Currently, Z-Best receives up to 1,000 tons per day of yard trimmings, which are processed into an organic compost and sold to Salinas Valley farmers for use on crops. Additionally, 350 tons per day of municipal solid waste and food waste is processed at Z-Best for sale to the local landscaping industry.Zanker has expanded its operations into the Sacramento region by permitting and establishing the Florin Perkins Public Disposal Site, a 500-ton per day material processing and transfer facility. This facility primarily processes construction and demolition debris (C&D) to assist the City of Sacramento and neighboring communities with C&D diversion goals. Similar to Zanker’s San Jose operations, the FPDS assists customers in a professional, courteous manner and leads the C&D recycling in Sacramento County.

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 forresidents 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. 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.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. This facility consists of a patented combination of conveyors, screens, magnets and air separation equipment that separates the materials into manageable and marketable products. These products are than directed to other recycling operations on site or shipped directly to end product users.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. The concrete recycling process begins with incoming clean concrete and reinforced concrete. Once the materials are unloaded at the site, non-acceptable materials are hand sorted out and recycled or disposed. Cleaned concrete is then loaded into the primary crusher where it is crushed. After the primary crusher, the material passes under a belt magnet where steel is removed before moving to a secondary crusher that further reduces the particle size. The material is then screened to remove oversized pieces which are re-circulated back through the crushing circuit. During the entire process, employees and machinery remove non-aggregate materials that would compromise the products value. 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. To view these materials as well as all the other products carried by Zanker,

s 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 , 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.
