Project Description Tracy Material Recovery Facility and Transfer Station Expansion 30703 S. MacArthur Drive, Tracy, Caftmia 95377 The Material Recovery Facility processes recyclables from commercial sources. Select commingled recyclables deliveries containing loads of recyclable material that may vary from 50% to 90% recyclable will be dumped in Material Recovery Facility. Material that will be recycled includes aluminum cans, ferrous metals, plastic, newspaper and magazines, plastic, paper, cardboard and glass. The separated material will then be baled and delivered to wholesalers. Material will be added or deleted from the recyclable stream as the market conditions dictate. Wheel loaders operating in the Material Recovery Facility push -the unprocessed recyclables into,the feed hopper of the sorting system. From the feed hopper, material will be conveyed to the sorting line. Newspaper, cardboard, glass, aluminum, ferrous, and plastic containers will be sorted and dropped into bays under the sorting conveyer. Materials to be baled will be pushed onto a conveyor belt feeding into the baler or be pushed directly to the baler as appropriate. Glass materials will be dropped into bins for transport to the recycle market. Full bins will be carried by forklift outside of the building for temporary covered storage along the west side of the MRF/TS building. Residual wastes that can not be recycled will stay on the sorting line where another conveyor belt will drop the residuals on the Transfer Station floor for transfer and disposal. T i heprimary Material RecoveryFacilit stationaryequipment will consist of: In-ground and elevated conveyor belts • Screens • 80 foot Elevated Sort Line • Baler Food Waste Processing: The food waste processing equipment would be located inside the Material Recovery Facility. The proposed equipment for the facility includes a hopper, sort line conveyor, sort line grinder feed conveyor, hammer mill grinder, grinder discharge conveyor and stacking conveyor for loading a truck or bins to transport separated food waste to a compost or anaerobic digestion facility. Prior to grinding, the food waste is required to be free of plastic and other contaminants (up to 10% residual) that could cause damage to the grinder or be deleterious to the digestion process. Plastic and other contaminant material will be removed manually on the sort line. A horizontal hammermill grinder is proposed for the use with this operation. Material is fed through a feed conveyor into the hammermill grinder. The hammers, which are attached to a rotor or shaft, impact the feed material, breaking it into smaller pieces. Below the hammer circle is a series of cast grates. The material remains inside the hammermill and is crushed or torn between the hammers and grates until its size is sufficiently reduced to pass through the grates where it is discharged onto a conveyor below. 23 170.18-03 CUP Project Description 050710 t
