The Resource Recovery Project would further modify current waste management operations at the Tajiguas Landfill by the addition of a Materials Recovery Facility (MRF) and Dry Fermentation Anaerobic Digestion (AD) Facility.
The MRF processing area would be comprised of an approx. 56,500 sq. ft. facility (66-500 sf if CSSR [optional element] is included) that would sort MSW into three streams:
Recyclables (i.e., glass, metal, paper, plastic, wood) - recovered and processed for sale;
-Organics - recovered for processing in the Anaerobic Digestion Facility; and
Residue - materials left over after all recyclables and organics are recovered that would be disposed of at the existing landfill.
The AD Facility would be housed within an approx. 63,600 sf building, and associated energy facility and percolate storage tanks that would convert all organics recovered from the MSW and SSOW into:
- Bio-gas (primarily composed of methane and CO2) - that would be used to power two 1,573 horsepower onsite combined heat and power (CHP) engines driving electric power generators that would generate approx. 1+ net megawatts (MW) of renewable power continuously. The Energy Facility would be located on the south side of the AD Facility;
Digestate - that can then be cured into compost and/or soil amendments. The curing would require an approx. 5 acre on the landfill top deck. The compost and/or soil amendments would be marketed for agricultural or landscape use or used for reclamation projects.
Construction of the facility (MRF, AD Facility and Composting Area) would require approx. 143,625 cubic yards of cut and 167,595 cubic yards of fill. The MRF would have a design capacity of up to 800 tons/day of MSW or up to approx. 250,000 tons//per year (up to 3111 operating days per year). Up to 90,000 tons/year (290 tons/day of recyclable material would be recovered and sold for reuse. The AD facility would have a design capacity of up to 73,600 tons/year, made up of organics recovered from the MRF and/or brought to the project site as SSOW.
Up to 100,000 tons/year (320 tons/day) of residue from the MRF and residue from the AD Facility which is not suitable for composting would be landfilled. Residue ineligible for disposal in the landfill (i.e., hazardous waste or e-waste), would be transported to an appropriate recycling or disposal facility.
