INCINERATIONINCHINA

Background

ChinahasbecomethelargestproducerintheworldintermsofMSWgeneration.Intheyear2004,Chinaurbanareasolidwastegenerationhasexceeded19milliontons.(WorldBank,2005)ThelargequantityofMSWhasposedChinaagreatthreattotheeffectivemanagementofthewaste.Incineration,togetherwithcomposting,landfillanddumpingsitehasbecomethemajorsolutiontotheMSWinChina.Bytheyear2002,thereare19Municipalwasteincinerationplants,with7thousandtonscapacityperday.(B.SolenthalerandR.Bunge2004)

Intermsofcapacity,incinerationisnotthemajorsolutiontoChina’sMSWmanagement.However,itisstillveryimportantcomponentinChina’swastemanagementsystem.Below,wewillanalysistheadvantagesanddisadvantagesofincinerationinChina.

InthecircumstanceofChina,incinerationhasthefollowingadvantagescomparingwithlandfill.ThequantityofMSWinChinaisverybig.Thelargequantityrequiresawaytoeffectivelyreducethevolumeandweightofthewaste.However,Landfillrequiresspaceandland,whichisbecomingscarceinChina.MSWishighlyconcentratedinurbanarea,wherelanduseisacrucialduetothescarcityofland.Chinaisacountrywithlargepopulationdensity.Intheeastandcostalregion,wheretheeconomyismoredeveloped,theconcentrationofpopulationismuchhigher.Intheseregions,theconflictbetweenurbanexpansionandlandscarcityisbecomingmoresalientinrecentyears.

ChallengesofincinerationinChina

Fromenvironmentalperspective,thechallengesfromincinerationareveryserious.ThemajorconcernofwasteincinerationistheemissionofheavymetalandDioxins.ChinesegovernmenthassetthestandardfortheDioxins.On1st.June2000,ChineseSEPA(StateEnvironmentprotectionAgency)hasissued“StandardforWasteIncinerationPollutionControl”ItsetsthestandardfortheDioxinsemissionas1.0Nanogram/M³.However,thesamestandardforEU,NorthAmericaandJapanis0.1Nanogram/M³.(WB2005)

Therearethreemajortypesofemissionfromincineration:stackemission,flyashandbottomash.AccordingtoB.SolenthalerandR.Bunge,theconcentrationofnonferrousmetalsinChinaisonly0.24%.ComparingwithSwitzerlandof3%,theChinesenumberisverylower,whichmakesitimpossibletoutilizethebottomashfornonferrousmetalrecycle.(2004)

However,theHgcontaminationinbothfly-ashandbottomashisaseriousproblem.AccordingtoWorldBank,the50%oftheHgdepositedintheNorthAmericalakecomesfromChinesewasteincinerator.

Heatrecovery:ThecompositionofChina’sMSWisquitediverse.Thecompositioninsomebigcities,suchasBeijingandShanghai,aresimilartothatofwesterncountries.However,inmostofthesmallandmediumcities,thecompositionisdifferent.Thecompositionofwastedeterminestheheatvalueoftheincineration.TheaverageheatvalueofChinais5MJ/kg,whichislowerthanthatofrequirementofheatvalueof6MJ/kgforincineration.Thus,thesupplementfuelisrequiredforincineration.Thismakesitimpossibletogainnetenergygenerationtocompensatethehighinvestment.(SolenthalerandBunge2004)

REUSEANDRECYCLEINCHINA
