Designation:D670001(Reapproved 2013)Standard Practice forUse of Scrap 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 practice covers and provides guidance for thematerial recovery of scrap tires for their fuel value.Theconversion of a whole scrap tire into a chipped formed for useas a fuel produces a product called tire-derived fuel(TDF).This recovery practice has moved from a pioneering concept inthe early 1980s to a proven and continuous use in the UnitedStates with industrial 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 practice 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 require tireprocessing 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D2013 Practice for Preparing Coal Samples for AnalysisD2361 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 Test Method for Moisture in the Analysis Sample ofCoal 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 SizeD5468 Test Method for Gross Calorific and Ash Value ofWaste MaterialsD5865 Test Method for Gross Calorific Value of Coal andCokeE873 Test Method for Bulk Density of Densified ParticulateBiomass Fuels2.2 Other Standards:SW-8465050 Bomb Calorimeter PreparationSW-8469056 Ion Chromatography1This practice 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.1,2013.Published February 2013.Originallyapproved in 2001.Last previous edition approved in 2006 as D6700-01(2006).DOI:10.1520/D6700-01R13.2For 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 States1 3.Terminology3.1 Definitions:3.1.1 all season radial,na highway tire designed to meetthe weather conditions in all seasons of the year,that meets theRubber Manufacturers Association4definition of a mud andsnow tire.3.1.2 altered tire,na scrap tire which has been modifiedso that it is no longer capable of retaining air,holding water,orbeing used on a ve
