Nyob rau hauv ob lub rooj sib tham ntawm National People's Congress xyoo no, Ma Yongsheng, tus thawj coj ntawm Sinopec Group thiab tus tuav ntaub ntawv ntawm Party Group, tau hais tias peb yuav tsum koom tes nrog kev siv cov khoom siv pov tseg los ua cov peev txheej, ua kom muaj kev hloov pauv ntsuab thiab kev tsim kho kom zoo dua qub. Kev lag luam tshuaj lom neeg, ua kom nrawm nrawm ntawm lub voj voog yas, thiab tsim kom muaj kev lag luam zoo thiab kev siv nyiaj txiag loj.
Cov ntaub ntawv qhia tau hais tias tam sim no, Tuam Tshoj tsim ntau tshaj 60 lab tons ntawm cov khib nyiab yas txhua xyoo, thiab cov khoom siv rov ua dua tshiab ntawm cov yas khib nyiab yog li 30%, uas yog nyob rau hauv pem hauv ntej ntawm lub ntiaj teb. Txawm li cas los xij, vim muaj kev faib ua feem ntau ntawm qhov chaw pov tseg thiab kev tua hluav taws, qhov kev rov zoo tag nrho tseem muaj chav loj rau kev txhim kho. Kev rov ua dua tshiab ntawm cov yas pov tseg tam sim no tau lees paub thoob ntiaj teb tias yog cov pa roj carbon tsawg, huv thiab tib txoj kev rov ua dua tshiab uas tuaj yeem ua tiav kev txhim kho kom ruaj khov, thiab nws tseem yog txoj hauv kev zoo los txhim kho kev rov ua dua tshiab ntawm cov yas pov tseg. Nyob rau hauv kev pom ntawm ntau tus neeg sab hauv kev lag luam, yas ncig kev lag luam tuyere tau tuaj txog.
Tus nqi rov qab yuav tsum tau txhim kho
Raws li lub teb chaws loj ntawm kev tsim thiab siv cov yas, Tuam Tshoj tab tom ntsib lub siab loj ntawm cov pa phem yas. Lub Xeev Pawg Saib Xyuas thiab cov haujlwm tseem ceeb tau tshaj tawm ntau txoj cai rau kev tswj hwm cov pa phem.
Xyoo 2021, National Development thiab Reform Commission thiab Ministry of Ecology thiab Ib puag ncig tau tshaj tawm tsab ntawv ceeb toom los ntawm Kev Tshaj Tawm "14th Tsib Xyoo Plan" Action Plan on Plastic Pollution Control, xav kom ceev cov txheej txheem rov ua dua tshiab thiab siv cov pov tseg yas, tsom mus rau kev txhim kho. theem ntawm kev nyab xeeb pov tseg ntawm cov yas pov tseg xaus, siv zog ua haujlwm tshwj xeeb tu thiab kho dua tshiab ntawm cov pov tseg yas, thiab txo qis cov khoom pov tseg yas pov tseg thiab ib puag ncig to. Peb tau ua tiav qhov tseem ceeb hauv kev tswj cov pa phem dawb.
Nws tau nkag siab tias txoj kev kho cov yas khib nyiab tam sim no feem ntau suav nrog kev rov ua dua tshiab, incineration thiab landfill. Ntawm lawv, kev rov ua dua tshiab yog ib txoj hauv kev siv lub cev, uas yog, nws tsis rhuav tshem cov txheej txheem polymer ntawm cov yas, thiab tsuas yog cov yas khib nyiab ncaj qha pelletized tom qab ntxuav thiab crushing. Cov ntaub ntawv los ntawm Tuam Tshoj Cov Khoom Siv Rov Ua Dua Tshiab qhia tias xyoo 2021, 62 lab tons ntawm cov khoom pov tseg yas yuav raug tsim nyob hauv Suav teb, ntawm 15.4 lab tons yuav raug faus, suav txog 24.84%; Lub incineration ntim yog 27.6 lab tons, accounting rau 44.52%; Tus nqi ntawm kev rov ua dua tshiab yog 19 lab tons, nce 3 lab tons, lossis 19%, los ntawm 16 lab tons hauv 2020, thiab tag nrho cov khoom siv rov ua dua tshiab ntawm cov yas khib nyiab yog 30.64%.
"Tuam Tshoj pib cov khoom pov tseg yas rov ua dua tshiab hauv xyoo 1980s, tom qab ze li 40 xyoo ntawm kev siv zog, peb tau tsim muaj lub hauv paus muaj zog, tsim kev lag luam nplua nuj, thiab tsim ib lub network rov ua dua uas npog qhov dav thiab loj loj pov tseg cov yas rov ua dua tshiab; Nws muaj. tsim lub ntiaj teb ua tiav cov khoom pov tseg yas rov ua dua tshiab thiab rov ua dua tshiab kev lag luam. " Wang Yonggang, tus tuav ntaub ntawv ntawm Plastics Recycled ceg ntawm Tuam Tshoj Materials Recycling Association, hais rau Tuam Tshoj Zog Xov Xwm.
Txawm li cas los xij, Wang Yonggang tau piav qhia ntxiv tias: "Txawm hais tias qhov kev rov ua dua tshiab ntawm cov khoom siv pov tseg hauv Suav teb yog qhov siab tshaj plaws hauv ntiaj teb, qhov kev faib ua feem ntawm qhov chaw pov tseg thiab kev tua hluav taws tseem loj heev, thiab kev lag luam rov ua dua yuav tsum ua lub luag haujlwm hauv kev txhim kho cov khoom siv hauv tsev. system kom nce tus nqi rov ua dua kom ntau li ntau tau. "
Zhang Songchen, tus thawj tswj hwm ntawm Tuam Tshoj Petrochemical Research Institute of Circular Economy, tau sau tias: "Cov txiaj ntsig yav tom ntej los ntawm cov cai tswjfwm, qib roj nqi, cov neeg siv khoom nyiam rau kev tiv thaiv ib puag ncig, thev naus laus zis kom loj hlob thiab lwm yam ntau yam, xav kom txog xyoo 2030, lub ntiaj teb rov ua dua tus nqi. ntawm cov khoom pov tseg plastics yuav tsum ncav cuag 50%. "
Tshuaj rov qab txoj kev
Lub npe hu ua chemical recycling yog hais txog kev hloov pauv ntawm polymer carbon chains hauv plastics rau hauv cov khoom me me los ntawm cov txheej txheem tshuaj, thiab tom qab ntawd rov siv los ua cov ntaub ntawv raw los tsim cov yas tshiab, kom ua tiav cov txheej txheem kaw cov ntaub ntawv. Nyob rau hauv xyoo tas los no, cov tuam txhab tshuaj lom neeg thoob ntiaj teb tau nrawm lawv cov txheej txheem hauv kev tsim cov yas rov ua dua tshiab, thiab ntau dua 60 lub tuam txhab thoob ntiaj teb tab tom tshawb nrhiav cov tshuaj rov ua dua tshiab rau cov yas pov tseg.
"Kev kho cov yas khib nyiab ib txwm siv tsis yog tsuas yog coj ntau thaj av ua haujlwm thiab ua paug, tab sis kuj tsim cov pa roj carbon dioxide ntau." Raws li cov thev naus laus zis tshiab uas tau nyiam ntau xyoo tsis ntev los no, kev rov ua dua tshiab ntawm cov yas pov tseg tsis tuaj yeem tsuas yog txo cov pa roj carbon emissions ntawm cov khoom siv pov tseg thiab cov pa roj carbon hneev taw ntawm cov yas tshiab, tab sis kuj txo qis Tuam Tshoj txoj kev vam khom rau cov roj crude. " Sinopec Petrochemical Science Research Institute Co., Ltd. senior engineer Li Mingfeng hais tias.
Raws li kev tshawb fawb tau los ntawm Sinopec Petrochemical Research Institute Co., LTD., pov tseg cov roj yas hloov cov roj crude hauv cov roj refinery ua, thiab nws cov pa roj carbon emissions thaum lub sij hawm ua yog txo los ntawm 58.9%; Thaum cov roj hmab pov tseg tau ua kom ntau tshaj plaws los tsim cov polyolefin, cov pa roj carbon hneev taw ntawm polyethylene thiab polypropylene cov khoom (carbon dioxide emissions ib chav tsev ntawm polyolefin) yog 1.48 tons thiab 1.17 tons, raws li, uas yog 26.4% thiab 24.0% qis dua cov roj crude raws li polyolefin. Txawm hais tias nws yog kev tsim cov khoom siv roj siv cov khoom siv pov tseg raws li cov khoom siv raw, los yog lub voj voog ntawm cov khoom siv khib nyiab los tsim cov polyolefin, carbon emissions thiab cov khoom carbon footprint yuav raug txo kom tsawg, thiab cov emission txo cov nyhuv yog pom tseeb.
"Lub cev rov ua dua tshiab ntawm cov khoom pov tseg plastics feem ntau degrades kev siv cov ntaub ntawv. Qee cov pov tseg plastics tej zaum yuav tsim nyog rau kev rov ua dua tshiab, uas tuaj yeem depolymerize cov yas pov tseg thiab rov ua dua rau hauv cov ntaub ntawv yas. Tam sim no, Tuam Tshoj txoj kev vam khom rau cov roj crude yog siab, qhov tsis txaus. ntawm chemical raw cov ntaub ntawv, thiab cov chemical recycling ntawm pov tseg plastics yog theoretically unlimited recycling, uas zoo heev txhim kho cov efficiency ntawm kev siv. " Wang Yonggang hais.
"Cov khoom siv yas pov tseg muaj peev xwm los ua ib qho tseem ceeb ntawm cov khoom siv raw rau kev tsim tshuaj lom neeg. Nws kwv yees tias cov yas rov ua dua tshiab raws li cov khoom siv polymer tuaj yeem pab txhawb ob feem peb ntawm cov txiaj ntsig kev loj hlob hauv kev lag luam petrochemical hauv 10 xyoo tom ntej, nrog tshuaj lom neeg. recycling accounting rau 40% ntawm qhov no. " Tuam Tshoj petrochemical ncig kev lag luam tshawb fawb lub koom haum tus thawj tswj hwm Zhang Songchen tau hais.
Txhawb kev txhim kho ntawm cov saw hlau ncig
Tam sim no, kev tshawb fawb txog kev siv thev naus laus zis thev naus laus zis ntawm cov khoom siv pov tseg hauv Suav teb yog qhov pib synchronized nrog cov teb chaws txawv teb chaws, tab sis tseem muaj teeb meem xws li kev nkag mus tau yooj yim rau cov khoom siv raw, kev paub tab yuav tsum tau txhim kho, thiab tag nrho cov kev npaj muaj peev xwm ntawm tag nrho cov kev lag luam. saw yog tsis txaus, uas yuav tsum tau ceev nrooj tsim ib tug industrialization ua qauv qhia, thiab tsim kom muaj ib tug ua tiav chemical voj voog industrial saw thiab raw cov ntaub ntawv thiab cov khoom raws li tus qauv system.
Ma Yongsheng tau hais tias: "Ua ntej, peb yuav tsum ntxiv dag zog rau cov qauv tsim ntawm kev lag luam ncig kev lag luam. Nyob rau hauv lub teb chaws, tag nrho cov kev tsim kho lub voj voog ntawm cov yas khib nyiab yog tsim, ib txoj cai tswj kev tsim, thiab kev lag luam. Cov saw hlau tau raug txhawb nqa, qhov thib ob, peb yuav ntxiv dag zog rau kev tshawb fawb hauv cov thev naus laus zis tseem ceeb thiab cov thev naus laus zis hauv lub tebchaws, peb yuav koom tes nrog kev tshawb fawb sib koom ua ke ntawm kev tsim khoom, kev kawm thiab kev tshawb fawb, txhawb kev sib koom tes tsim kho tshiab, thiab coj tus thawj coj ntawm cov tuam txhab petrochemical kom nce qib. txoj kev loj hlob ntawm cov thev naus laus zis tseem ceeb rau kev rov ua dua cov khoom pov tseg plastics thiab tsim kom muaj kev lag luam ua qauv qhia sai li sai tau; Thib peb, peb yuav ntxiv dag zog rau tsoomfwv cov lus qhia txog kev siv cov peev txheej tsim nyog.Ua kom muaj txiaj ntsig zoo ntawm kev faib cov khoom pov tseg uas tsis tshua muaj nqi pov tseg raws li kev qhia ntawm tsoomfwv, kev npaj. thiab layout ntawm recycling tes hauj lwm thiab kev tsim kho ntawm pawg infrastructure, thiab txhim kho cov efficiency ntawm kev siv cov peev txheej. "
"Txawm hais tias lub xeev tau muab cov yas rov ua dua tshiab rau hauv kev lag luam tawm tshiab, vim tias kev lag luam tau muab qhov kev xav ntawm 'kev ua qias tuaj me me' yav dhau los, qhov project yog qhov nyuaj rau thaj av hauv cheeb tsam." Kev lag luam pov tseg plastics txhawb kev sib raug zoo metabolism, uas yog tib yam li cov chaw kho dej phwj thiab cov chaw kho mob pov tseg hauv cov nroog loj, thiab yog ib qho kev pabcuam uas txhawb kev loj hlob ntawm kev sib raug zoo. Ua ntej ntawm tag nrho cov, pib los ntawm kev lag luam qhov chaw, cov yas rov ua dua tshiab yuav tsum ua kom tiav nyob rau ntau qhov chaw; Qhov thib ob, cov tuam txhab ua lag luam yuav tsum tau tsav lub zuag qhia tag nrho kev loj hlob ntawm kev lag luam nyob rau hauv ib qho kev coj zoo; Tsis tas li ntawd, peb yuav tsum ua kom zoo dua cov saw hlau ua lag luam, cia cov kev lag luam sab saud thiab qis qis sib koom tes, thiab ua txoj haujlwm zoo ntawm kev lag luam kev sib koom ua ke, kev sib koom ua ke thiab kev txhawb nqa. "" Wang Yonggang tau hais.
