"Tuam Tshoj txoj kev kho cov khib nyiab tiag tiag muaj kev ua tau zoo ntawm cov peev txheej, tab sis muaj kev ntxhov siab; nws cov pa hluav taws xob hauv tsev cog khoom yog nyob rau theem tseem ceeb, tab sis qhov no tsis tau lees paub; kev kho cov khoom pov tseg hauv tsev qis qis - cov pej xeem- thaj chaw ntom ntom tseem tab tom tshawb nrhiav, tsis muaj kev tshuaj xyuas dav dav; muaj qhov sib txawv ntawm kev xav tau ntawm thaj av, kev nkag siab thiab kev hloov pauv ntawm thaj av. ex-kev kho qhov chaw pov tseg, tab sis qhov tsis txaus ntawm cov peev nyiaj;
Thaum Lub Kaum Ob Hlis 17, ntawm 2025 (19th) Lub Rooj Sib Tham Cov Khoom Siv Khib Nyiab, Xu Haiyun, Tus Thawj Kws Ua Haujlwm ntawm Tuam Tshoj Lub Nroog Tsim Tsim & Tshawb Fawb Lub Tsev Haujlwm, tau hais lus hu ua "Rau Qhov Zoo Tshaj Plaws: Ib Txoj Kev Sib Piv Thoob Ntiaj Teb thiab Yav Tom Ntej Strategic Pathways for China's Household Waste Treatment." Los ntawm kev xav thoob ntiaj teb, nws tau muab piv rau rau qhov kub - khawm teeb meem hauv Tuam Tshoj txoj kev kho cov khib nyiab thiab tshawb xyuas lawv qhov tob.
Raws li Tuam Tshoj Lub Nroog- Phau Ntawv Qhia Txog Kev Tsim Kho Hauv Nroog (tsis suav nrog cov khoom siv rov ua dua tshiab los ntawm cov neeg khaws pov tseg), ntim cov khoom pov tseg hauv nroog thauj mus rau kev kho mob hauv Tuam Tshoj lub nroog thiab cov nroog hauv xyoo 2024 yog 319 lab tons, uas kwv yees li 30 lab tons tau cais cov khoom noj. Cov ntaub ntawv los ntawm Tuam Tshoj National Resources Recycling Association qhia tau hais tias nyob rau hauv 2024, lub ntim ntawm cov ntaub ntawv pov tseg rov ua dua yog 69.71 lab tons, thiab cov khoom siv pov tseg rov ua dua yog 19.5 lab tons. Tus nqi ntawm tsev neeg- cov khoom siv rov ua dua yog kwv yees li ntawm 100 lab tons. Tag nrho cov khoom pov tseg hauv tsev tau tsim xyoo 2024 (xws li cov khoom siv rov ua dua los ntawm cov neeg khaws pov tseg) kwv yees li ntawm 420 lab tons, sib npaug li 0.81 kilograms ib tus neeg hauv ib hnub, nrog rau cov khoom pov tseg rov qab ntawm kwv yees li 31%.
Los ntawm kev xav thoob ntiaj teb, piv nrog cov ntaub ntawv los ntawm cov teb chaws tsim, Tuam Tshoj cov khoom pov tseg ntawm ib tus neeg hauv tsev neeg tsawg dua li ntawm Singapore - txawm tias suav nrog cov khoom siv rov ua dua los ntawm cov neeg khaws khoom pov tseg, nws tseem qis dua hauv Tebchaws Yelemees lossis Tebchaws Meskas. Hais txog cov peev txheej rov qab los, Tuam Tshoj tus nqi ntawm 31% twb dhau los ntawm cov tebchaws tsim kho xws li Singapore thiab Nyij Pooj.
Xu Haiyun tau tsa cov lus nug: txij li Tuam Tshoj cov peev txheej rov qab los tau dhau los ntawm cov teb chaws tsim, vim li cas thiaj tseem muaj kev ntxhov siab loj hauv cheeb tsam no? Nws tau sib cav tias muaj qhov sib txawv hauv cov tebchaws li cas suav lawv cov ntaub ntawv pov tseg hauv tsev. Hauv Tebchaws Meskas, piv txwv li, cov ntaub ntawv tshaj tawm ib tus neeg hauv tsev neeg pov tseg hauv 2018 yog 2.22 kilograms ib hnub, zoo li qhov siab tshaj plaws hauv ntiaj teb. Txawm li cas los xij, daim duab no tsis yog raws li qhov hnyav tiag tiag -ins ntawm cov chaw kho mob tab sis muab los ntawm kev ua qauv, thiab cov ntaub ntawv txheeb cais tseem tsis tau hloov kho txij li xyoo 2018.
Nyob rau hauv lub teb chaws Yelemees, cov ntaub ntawv qhia txog ib tus neeg pov tseg ntawm 1.58 kilograms ib hnub qhia meej suav nrog ntau cov khoom pov tseg hauv vaj thiab lwm yam tsis yog - cov khib nyiab hauv tsev txhua hnub, ua rau nws cov ntaub ntawv txheeb xyuas dav dua li ntawm Tuam Tshoj. Piv txwv li, raws li Bavaria's 2023 cov ntaub ntawv pov tseg cov khoom pov tseg, tag nrho cov khoom pov tseg hauv tsev yog 6.37 lab tons, nrog rau kev rov ua dua ntawm 66%. Cov nroj tsuag incineration tau ua tiav 3.21 lab tons, nrog cov ntaub ntawv txheeb cais qhia txog 2.27 lab tons ntawm cov khib nyiab pov tseg. Tsis tas li ntawd, vaj pov tseg suav rau ib -feem peb ntawm tag nrho cov khoom siv rov ua dua tshiab.
Raws li qhov tseeb 2025 kev tshawb fawb los ntawm ib lub tuam txhab pab tswv yim hauv Teb Chaws Asmeskas, lub tsev cog khoom tso pa tawm los ntawm cov chaw pov tseg thoob ntiaj teb suav txog 4% ntawm tag nrho cov emissions - ua rau cov niche no tseem ceeb dua thaum piv rau cov tsoos siab - emission industries xws li hlau.
Saib ntawm lub tsev cog khoom roj tso tawm los ntawm Tebchaws Meskas, Tebchaws Europe, thiab Singapore rau xyoo 2022, methane emissions los ntawm US landfills tsim 17.1% ntawm tag nrho cov methane emissions, sib npaug rau 360 kilograms ntawm CO₂ sib npaug rau ib tus neeg. Hauv EU, methane emissions los ntawm qhov chaw pov tseg suav txog 2.4% ntawm tag nrho cov pa hluav taws xob hauv tsev cog khoom, lossis 160 kilograms ntawm CO₂ sib npaug rau ib tus neeg. Nyob rau hauv Singapore, methane emissions los ntawm landfills yog xoom, thiab tag nrho cov tsev xog paj emissions los ntawm cov pov tseg sector account rau 0.6% ntawm tag nrho lub teb chaws emissions, feem ntau yog los ntawm kev kho mob pov tseg incineration thiab dej khib nyiab.
Yog tias tag nrho Tuam Tshoj cov khoom pov tseg hauv tsev tau muab pov tseg rau hauv qhov chaw pov tseg, qhov tshwm sim ntawm cov pa hluav taws xob hauv tsev yuav yog qhov tseem ceeb. Piv txwv li, nyob rau hauv Hong Kong, lub tsev xog paj emissions los ntawm landfill pov tseg ntawm tsev neeg pov tseg nyob rau hauv 2023 muaj 2.92 lab tons ntawm CO₂ sib npaug, sawv cev 8.5% ntawm Hong Kong cov emissions tag nrho, nrog rau ib tug neeg emissions ntawm 390 kilograms ntawm CO₂ sib npaug.
Xu Haiyun tau hais tias yog Tuam Tshoj av loj yuav tsum tau txais cov khoom pov tseg zoo sib xws -raws li txoj kev pov tseg pov tseg raws li Hong Kong, ib tus tsuas tuaj yeem xav txog qhov ntsuas ntawm cov pa hluav taws xob hauv tsev cog khoom. Nws tau sau tseg tias kev siv cov khib nyiab niaj hnub no- rau- hluav taws xob incineration los hloov qhov chaw pov tseg tau ua rau muaj txiaj ntsig zoo rau kev txo qis cov pa hluav taws xob hauv tsev cog khoom hauv cov khib nyiab khib nyiab- qhov kev ua tiav tsis yog tsim nyog rau kev kawm los ntawm kev tsim lub teb chaws tab sis kuj rau cov teb chaws tsim.
Elec Barrel tseem cog lus rau cov hauv paus ntsiab lus ntawm cov neeg siv khoom- kev pabcuam thawj zaug thiab sab saum toj- cov khoom lag luam zoo, muab cov neeg siv khoom muaj txiaj ntsig zoo tshaj plaws -rau- cov khoom siv hlau khib nyiab thiab cov kev daws teeb meem pov tseg.
