4~1,2 City of Los CA Phase I10 In 2004, the City of Los Angeles, Bureau of Sanitation (Bureau) began a study to evaluate ;4SVV alternative treatment technologies capable of processing Black Bin material / residential MSVVl to significantly reduce the amount of such material going to landfills. The Bureau's overall objective was to select one or more suppliers to develop a facility using proven and commercialized technology to process the Black Bin material and produce usable by-products such as electricity, green fuel, and/or chemicals. The first step of this project was to develop e comprehensive list of potential technologies and suppliers. About 225 suppliers were screened, and 26 suppliers were selected to submit their detailed qualifications to the City. In order to screen the technology suppliers, they were sent a brief survey based upon the technology screening criteria. The criteria applied were aefollows: • Waste Treatabi|ity:The supplier was screened on whether they have MSVVor similar feedstock processing experience. • Conversion Performance: The supplier was asked if their facility would produce marketable byproducts. • Throughput Requirement: This criterion was already met because the technology passed the technology screen. • Commercial Status: This criterion was already met because the technology passed the technology screen. • Technology Capability: The supplier was asked if their technology had processed at least 25 tons per day offeedstock. Of the 26 suppliers requested to submit qualifications, seventeen provided responses. These suppliers and their technologies were thoroughly evaluated, and an Evaluation Report was published in September 2005 with the findings and ranking of the 26 suppliers' technologies that had met the criteria. A Request for Qualifications (QFO) was prepared and provided to the suppliers that met the screening criteria. A detailed technical and economic evaluation of the suppliers that responded to the RFO was completed. This resulted in the development of a short list of alternative treatment technology suppliers. In 2006, several suppliers were added to the short list, based on additional screening and a supplemental RFQprocmso. As part of the process, the City collected information on capital cost from the suppliers. Based on 18 responses, the capital cost per installed ton for anaerobic digestion ranged from $09,000 to $201,000; for gasification, the range was $50,000 to $266,000; for pyrolysis, the range was $60,000 to $221,000; one mixed waste 10 Request for Proposals fora Development Partner(s) for Processing Municipal Solid Waste Utilizing Alternative Technologies premised on Resource Recovery for the City of Los Angeles, February 5,2OO7.
