to the Orange County Landfill or out-of-county facilities. The County owns the local <br />municipal solid waste (y4SVV) landfill which is expected to reach capacity in the next <br />few years. A new County construction and demolition waste landfill area was <br />recently developed and is expected to last approximately 15-20 years depending on <br />rate of use. <br />Another solid waste management strategy the County may want to consider is third <br />in the hierarchy: waste processing to reduce the volume for land disposal. While <br />waste processing technologies (VVPT) can include methods of volume reduction <br />(shredding, compaction, baling, etc.), most such technologies involve some form of <br />controlled thermal treatment - incineration - with fuel production or energy <br />recovery. The County may want to consider the need to address such waste <br />processing technologies as possible alternatives to landfill disposal. The capital <br />intensive approaches such as VVTE require a sufficient quantity of waste to be cost <br />effective: the more waste, the lower the per ton price. <br />The purpose of this white paper is to initiate that evaluation and brief the County's <br />solid waste staff, elected officials, Solid Waste Advisory Board, and citizens on state- <br />of-the-art solid waste processing technologies, emerging technologies and their <br />applicability to the County's needs, and the potential of these technologies to <br />contribute to the County's overall solid waste management system. Section 3.0 <br />summarizes the future waste disposal needs identified in the Plan and how waste <br />processing could affect the amount of landfill disposal required. <br />Section 3.0 discusses the worldwide experience ofVVPT and respective vendors in the <br />United States and other countries, as some of these technologies have operating <br />demonstrations or facilities outside of the U.B. Section 4.0 reviews most of the <br />recent activity in the evaluation and procurement of waste processing technologies <br />by other U.S. cities and counties. These localities are exploring alternatives for <br />increasing their diversion rates, recovering more resources from their solid waste, <br />and delivering better service to their citizens. Section 5.0 explores the economic <br />feasibility, effectiveness, and environmental issues surrounding the use of the waste <br />processing technologies discussed. Section 6.0 presents opinions as to the most <br />applicable technologies for further consideration by the County. <br />Appendix B reviews .the available "proven" waste processing technologies, all of <br />which are inc|nmration-based, their track record and operating characteristics, and a <br />listing of facilities operating in the region. In addition, Appendix 8 details "ennerging" <br />waste processing technologies including high-temperature gasification, fluidized-bed <br />combustion, plasma-arc processing, and some non-thermal anaerobic digestion. <br />GBE/C08027-01 2 August 15,2OO8 <br />
