Grid connected integrated community energy system. Phase II: final state 2 report. Preliminary design waste management and institutional analysis
The Preliminary Design of a Regional, Centralized Solid Waste Management System for the Twin Cities Metropolitan Region in Minnesota is presented. The concept has been developed for the sound environmental and safe disposal of solid waste generated from its health care industry, although some additional waste supplements are included as economic assistance in order to approach a competitive alternative to current health care solid waste disposal costs. The system design focuses on a 132 tons per day high-temperature, slagging pyrolysis system manufactured by Andco Incorporated, Andco-Torrax Division Design criteria are given. A Collection and Transportation System (CTS) has been planned for the movements of solid waste (General and Special) from the generating HHC facilities within a 10-mile waste-shed zone, for municipal solid waste from a local transfer station currently processing municipal solid waste, and for pyrolysis residue to final disposal. Each of these facilities is now considered as service contract operations. Approximately 15 vehicle trips per day are estimated as vehicle traffic delivering the refuse to the pyrolysis facility. Cost estimates for the CTS have been determined in conjunction with current municipal refuse haulers in the TCMR, and valued at the following: HHC General Solid Waste (HHC/GSW) at 6.00 $/T; HHC Special Solid Waste (HHC/SSW) at 20.00 $/T; Municipal Transfer at 4.00 to be paid the pyrolysis system as a drop charge. Special box-bag containers are to be required in handling the HHC/SSW at a cost of 30.19 $/T estimate. The total operating cost for the pyrolysis system has been estimated to be 13.73 $/T, with a steam credit of 11.70 $/T, to yield a net cost of 2.03 $/T. Capital cost has been estimated to be 7,700,800 dollars, 1978. A back-up facility capital investment of $163,000 dollars, 1978 has been estimated, which should be applied to the existing University of Minnesota incinerator.
