Tau ntau xyoo, txoj hauv kev tseem ceeb ntawm kev rov ua dua cov yas yog cov khoom siv rov ua dua tshiab, uas feem ntau melts cov yas tawg thiab ua rau lawv mus rau hauv cov khoom tshiab.Txawm hais tias cov ntaub ntawv no tseem yog tib cov yas polymers, lawv lub sijhawm rov ua dua tshiab raug txwv, thiab txoj kev no yog nyob ntawm cov fossil fuels.
Tam sim no, cov khoom siv pov tseg hauv Suav teb feem ntau suav nrog cov yas zaj duab xis, yas xaim thiab cov khoom siv woven, foamed plastics, yas ntim cov thawv thiab cov thawv ntim khoom, cov khoom siv niaj hnub (cov raj mis yas, cov yeeb nkab fittings,ntim khoom noj, thiab lwm yam), cov hnab yas thiab cov yas ua liaj ua teb.Tsis tas li ntawd, txhua xyoo noj ntawmplastics rau tshebnyob rau hauv Suav teb tau mus txog 400000 tons, thiab txhua xyoo noj cov yas raucov khoom siv hluav taws xobthiab cov khoom siv hauv tsev tau mus txog ntau dua 1 lab tons.Cov khoom no tau dhau los ua ib qho tseem ceeb ntawm cov khoom pov tseg yas tom qab scrapping.
Niaj hnub no, ntau thiab ntau cov xim yog them rau tshuaj rov qab.Kev siv tshuaj lom neeg tuaj yeem hloov cov yas rau hauv cov roj, cov khoom siv raw ntawm cov khoom siv petrochemical thiab txawm tias monomers.Nws tuaj yeem siv tsis tau tsuas yog siv cov khoom pov tseg ntau dua, tab sis kuj txo qhov kev cia siab ntawm fossil fuels.Thaum tiv thaiv ib puag ncig thiab daws cov teeb meem ntawm cov pa phem, nws tuaj yeem txo cov pa roj carbon emissions.
Nyob rau hauv ntau yam yas tshuaj rov qab technologies, pyrolysis technology yeej ib txwm nyob rau hauv ib tug ua txoj hauj lwm.Hauv lub hlis tsis ntev los no, cov chaw tsim cov roj pyrolysis hauv Tebchaws Europe thiab Asmeskas tau nce mus rau ob sab ntawm Atlantic.Cov haujlwm tshiab ntsig txog cov khoom siv hluavtaws rov qab los kuj tseem tab tom tsim, ntawm plaub yog polyethylene terephthalate (PET) cov haujlwm, txhua tus nyob hauv Fabkis.
Piv nrog rau cov neeg kho tshuab rov qab, ib qho ntawm qhov tseem ceeb ntawm cov tshuaj rov qab yog tias nws tuaj yeem tau txais qhov zoo ntawm cov khoom qub polymer thiab cov yas zoo dua qub.Txawm li cas los xij, txawm hais tias cov tshuaj rov qab tuaj yeem pab cov kev lag luam yas rov ua dua tshiab, txhua txoj hauv kev muaj nws tus kheej tsis txaus yog tias nws yuav tsum tau siv rau ntawm qhov loj.
Cov khib nyiab yas tsis yog tsuas yog teeb meem ua paug thoob ntiaj teb, tab sis kuj yog cov khoom siv raw nrog cov ntsiab lus carbon siab, tus nqi qis thiab tuaj yeem tau txais thoob ntiaj teb.Kev lag luam ncig kuj tau dhau los ua kev txhim kho yav tom ntej ntawm kev lag luam yas.Nrog rau kev txhawb nqa ntawm catalytic thev naus laus zis, tshuaj lom neeg rov qab los qhia txog kev lag luam zoo.
