The Greater Detroit Resource Recovery Authority (Authority), which serves the area of the City of Detroit and provides MSW to a 3,000 TPD WTE plant, contracted with GBB to assist the Authority with the procurement of waste transfer services and numerous waste processing options.

GBB conducted field inspections and gained familiarity with the current GDRRA System which included the six-compactor unit Southfield Transfer Station and a 3,000 TPD waste-to-energy facility.

GBB reviewed the actual tonnages and all the different solid waste materials handled at these sites and developed a Request for Proposals (RFP) for waste services delivery, waste transfer station operations, yard waste composting responsibility, and ultimate disposal needs for end products not going to recycling.

GBB was responsible for the pre-proposal conference and assisted with the evaluation of private-sector proposals, including all their equipment, labor and costs provisions, and assisted in the contractor selection process.

The services outlined in the RFP that were developed by GBB included ten-year contracted costs associated with:

1. The delivery of municipal solid waste (MSW) from private sources or public sources outside the City of Detroit to the Authority’s Resource Recovery Facility (RRF)
2. Hauling of MSW from the Southfield Transfer Station to the RRF
3. Hauling of Bulky Waste from the Southfield Transfer Station to a disposal facility selected by the contractor
4. Hauling and composting of Yard Waste from the Southfield Transfer Station to a composting facility selected by the contractor
5. Hauling of selected Bulky Waste from the RRF to a disposal facility selected by the contractor
6. Hauling of separated metals from the RRF to an Authority-designated scrap market which included the hauling of:
   • Front-end separated ferrous metal recovered in the processing of the MSW
   • Back-end ferrous metal extracted from the Ash
   • Back-end non-ferrous metal extracted from the Ash
7. Hauling of, and the disposal of, the Ash, less separated metals, from the RRF to a disposal facility selected by the contractor
8. Hauling and disposal of Bypassed MSW from the RRF that may occasionally be bypassed in emergency situations to a disposal facility selected by the contractor
9. Hauling and disposal of Residual MSW from the processing of MSW into refuse-derived fuel (RDF) at the RRF to a disposal facility selected by the contractor
