Tire-derived fuel is composed of shredded tires. Tires may be mixed with coal or other fuels such as wood to be burned in concrete kilns, power plants, or paper mills. An EPA test program concluded that, with the exception of zinc emissions, potential emissions from TDF are not expected to be very much different from other conventional fossil fuels, as long as combustion occurs in a well-designed, well-operated and well-maintained combustion device.〔http://www.epa.gov/ttncatc1/dir1/tire_eng.pdf〕 ==Theory== Historically, there has not been any volume use for scrap tires other than burning that has been able to keep up with the volume of waste generated yearly. Tires produce the same energy as petroleum and approximately 25% more energy than coal,〔http://www.epa.gov/epaoswer/non-hw/muncpl/tires/tdf.htm〕 Burning tires is lower on the hierarchy of reducing waste than recycling, but it is better than placing the tire waste in a landfill or dump. There is a possibility for tire fires or the harboring of disease vectors such as mosquitoes.〔 Tire Derived Fuel is an interim solution to the scrap tire waste problem. Advances in tire recycling technology 〔http://news.discovery.com/tech/tech-to-end-tire-burning.html〕 might one day provide a solution other than burning by reusing tire derived material in high volume applications. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tire-derived fuel」の詳細全文を読む スポンサード リンク
