Designation:D670019Standard Guide forUse of Scrap Tires as Tire-Derived Fuel1This standard is issued under the fixed designation D6700;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide covers and provides guidance for the mate-rial recovery of scrap tires for their fuel value.The conversionof a whole scrap tire into a chipped formed for use as a fuelproduces a product called tire-derived fuel(TDF).This recov-ery guide has moved from a pioneering concept in the early1980s to a proven and continuous use in the United States withindustrial and utility applications.1.2 Combustion units engineered to use solid fuels,such ascoal or wood,or both,are fairly numerous throughout the U.S.Many of these units are now using TDF even though they werenot specifically designed to burn TDF.It is clear that TDF hascombustion characteristics similar to other carbon-based solidfuels.Similarities led to pragmatic testing in existing combus-tion units.Successful testing led to subsequent acceptance ofTDF as a supplemental fuel when blended with conventionalfuels in existing combustion devices.Changes required tomodify appropriate existing combustion units to accommodateTDF range from none to relatively minor.The issues of properapplications and specifications are critical to successful utili-zation of this alternative energy resource.1.3 This guide explains TDFs use when blended andcombusted under normal operating conditions with originallyspecified fuels.Whole-tire combustion for energy recovery isnot discussed herein,since whole-tire usage does not requiretire processing to a defined fuel specification.1.4 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D2013/D2013M Practice for Preparing Coal Samples forAnalysisD2361 Test Method for Chlorine in Coal(Withdrawn 2008)3D2795 Test Methods for Analysis of Coal and Coke Ash(Withdrawn 2001)3D3172 Practice for Proximate Analysis of Coal and CokeD3173/D3173M Test Method for Moisture in the AnalysisSample of Coal and CokeD3174 Test Method for Ash in the Analysis Sample of Coaland Coke from CoalD3175 Test Method for Volatile Matter in the AnalysisSample of Coal and CokeD3176 Practice for Ultimate Analysis of Coal and CokeD3177 Test Methods for Total Sulfur in theAnalysis Sampleof Coal and Coke(Withdrawn 2012)3D3178 Test Methods for Carbon and Hydrogen in theAnalysis Sample of Coal and Coke(Withdrawn 2007)3D3179 Test Methods for Nitrogen in the Analysis Sample ofCoal and Coke(Withdrawn 2008)3D3682 Test Method for Major and Minor Elements inCombustion Residues from Coal Utilization ProcessesD4239 Test Method for Sulfur in the Analysis Sample ofCoal and Coke Using High-Temperature Tube FurnaceCombustionD4326 Test Method for Major and Minor Elements in Coaland Coke Ash By X-Ray FluorescenceD4749 Test Method for Performing the Sieve Analysis ofCoal and Designating Coal Size1This guide is under the jurisdiction of ASTM Committee D34 on WasteManagement and is the direct responsibility of Subcommittee D34.03 on Treatment,Recovery and Reuse.Current edition approved Feb.1,2019.Published February 2019.Originallyapproved in 2001.Last previous edition approved in 2013 as D6700 01(2013).DOI:10.1520/D6700-19.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 D54
