Environmental Policy thiab Design Guidelines
Nyob rau hauv xyoo tas los no, kev hloov pauv huab cua thiab ntau hom kev ua qias tuaj tsis tu ncua, nyiam ntau thiab ntau lub teb chaws thiab cov lag luam 'kev saib xyuas, thiab cov teb chaws tau tshaj tawm txoj cai tiv thaiv ib puag ncig ib puag ncig.
United Nations Environment Assembly (UNEA-5) tau pom zoo cov kev daws teeb meem keeb kwm ntawm 2 Lub Peb Hlis 2022 kom xaus cov pa phem yas los ntawm 2024. Hauv cov koom haum, piv txwv li, Coca-Cola's 2025 lub ntiaj teb ntim yog 100% rov ua dua, thiab Nestlé's 2010 0 ntim yog % recyclable los yog reusable.
Tsis tas li ntawd, cov koom haum thoob ntiaj teb, xws li cov khoom lag luam hloov pauv hloov pauv kev lag luam CEFLEX thiab cov neeg siv khoom siv txoj kev xav CGF, kuj tau muab tso rau hauv kev lag luam kev lag luam tsim qauv thiab cov qauv tsim golden raws li. Ob txoj hauv kev tsim qauv no muaj cov lus qhia zoo sib xws hauv kev tiv thaiv ib puag ncig ntawm kev ntim khoom yooj yim: 1) Cov khoom siv ib leeg thiab tag nrho-polyolefin yog nyob rau hauv qeb ntawm cov khoom siv rov ua dua tshiab; 2) Tsis pub PET, nylon, PVC thiab cov ntaub ntawv degradable; 3) Barrier txheej txheej Cov tier tsis tuaj yeem tshaj 5% ntawm tag nrho.
Yuav ua li cas technology txhawb ib puag ncig tus phooj ywg saj zawg zog ntim
Raws li kev pom zoo ntawm kev tiv thaiv ib puag ncig cov cai tawm hauv tsev thiab txawv teb chaws, yuav ua li cas txhawb kev tiv thaiv ib puag ncig ntawm kev ntim khoom yooj yim?
Ua ntej ntawm tag nrho cov, ntxiv rau degradable cov ntaub ntawv thiab technologies, txawv teb chaws manufacturers tau nqis peev nyob rau hauv txoj kev loj hlob ntawmyas rov siv dua thiab bio-based plastics thiab khoom. Piv txwv li, Eastman ntawm Tebchaws Meskas tau nqis peev hauv polyester rov siv thev naus laus zis, Toray ntawm Nyij Pooj tshaj tawm kev txhim kho bio-based nylon N510, thiab Suntory Group ntawm Nyiv tshaj tawm thaum Lub Kaum Ob Hlis 2021 tias nws tau ua tiav 100% bio-based PET lub raj mis qauv. .
Secondly, nyob rau hauv teb rau lub domestic txoj cai ntawm kev txwv ib leeg-siv plastics, ntxiv rau covCov khoom siv degradable PLA, Tuam Tshoj kuj tau nqis peevhauv kev txhim kho ntau yam khoom siv degradable xws li PBAT, PBS thiab lwm yam ntaub ntawv thiab lawv cov kev siv cuam tshuam. Cov khoom ntawm lub cev ntawm cov khoom degradable puas tuaj yeem ua tau raws li cov kev xav tau ntawm ntau qhov kev xav tau ntawm kev ntim khoom yooj yim?
Los ntawm kev sib piv ntawm lub cev muaj zog ntawm petrochemical films thiab degradable films,cov khoom thaiv ntawm cov khoom degradable tseem nyob deb ntawm cov yeeb yaj kiab ib txwm muaj. Tsis tas li ntawd, txawm hais tias muaj ntau yam khoom thaiv tuaj yeem rov coated ntawm cov ntaub ntawv degradable, tus nqi ntawm cov ntaub ntawv txheej thiab cov txheej txheem yuav raug superimposed, thiab daim ntawv thov cov ntaub ntawv degradable hauv cov pob mos, uas yog 2-3 npaug ntawm tus nqi ntawm thawj petrochemical zaj duab xis. , nyuaj dua.Yog li ntawd, kev siv cov ntaub ntawv degradable nyob rau hauv cov khoom ntim tau yooj yim kuj yuav tsum tau nqis peev hauv kev tshawb fawb thiab tsim cov khoom siv raw los daws cov teeb meem ntawm lub cev thiab cov nqi.
Kev ntim khoom yooj yim muaj kev sib xyaw ua ke ntawm ntau yam khoom kom tau raws li cov khoom xav tau rau tag nrho cov tsos thiab kev ua haujlwm ntawm lub ntim. Kev faib tawm yooj yim ntawm ntau hom yeeb yaj kiab nrog rau kev luam ntawv, kev ua haujlwm thiab kev sib khi thaum tshav kub kub, cov ntaub ntawv siv feem ntau yog OPP, PET, ONY, aluminium ntawv ci lossis aluminized, PE thiab PP cov ntaub ntawv kub sealing, PVC thiab PETG tshav kub shrinkable films thiab tsis ntev los no nrov MDOPE nrog. PEB.
Txawm li cas los xij, los ntawm kev xav ntawm kev lag luam ncig ntawm kev rov ua dua thiab rov siv dua, cov qauv tsim ntawm CEFLEX thiab CGF rau kev lag luam ncig ntawm kev ntim khoom yooj yim zoo li yog ib qho ntawm cov lus qhia ntawm kev tiv thaiv ib puag ncig ntawm kev ntim khoom yooj yim.
Ua ntej tshaj plaws, ntau cov ntaub ntawv ntim tau yooj yim yog PP ib qho khoom siv, xws li cov noodle ntim ntim BOPP / MCPP, cov khoom siv sib xyaw no tuaj yeem ua tau raws li cov khoom siv ntawm kev lag luam ncig.
Thib ob,Nyob rau hauv cov xwm txheej ntawm cov txiaj ntsig kev lag luam, kev tiv thaiv ib puag ncig ntawm kev ntim khoom yooj yim tuaj yeem ua raws li cov qauv ntim khoom (PP & PE) yam tsis muaj PET, de-nylon lossis tag nrho cov khoom siv polyolefin. Thaum cov ntaub ntawv bio-based lossis ib puag ncig cov ntaub ntawv muaj kev cuam tshuam ntau dua, cov ntaub ntawv petrochemical thiab aluminium foils yuav maj mam hloov kom ua tiav cov qauv zoo ib puag ncig zoo dua.
Thaum kawg, los ntawm kev xav txog kev tiv thaiv ib puag ncig thiab cov yam ntxwv ntawm cov khoom siv, feem ntau yuav muaj kev tiv thaiv ib puag ncig rau kev ntim khoom yooj yim yog tsim cov kev tiv thaiv ib puag ncig sib txawv rau cov neeg siv khoom sib txawv thiab cov khoom ntim sib txawv xav tau, tsis yog ib qho kev daws teeb meem, xws li ib qho khoom siv PE. , degradable yas los yog ntawv, uas yuav siv tau rau ntau yam kev pab scenarios. Yog li ntawd, nws tau pom zoo tias nyob rau hauv qhov ua tau raws li qhov yuav tsum tau ua ntawm cov khoom ntim khoom, cov khoom siv thiab cov qauv yuav tsum maj mam hloov mus rau qhov kev npaj tiv thaiv ib puag ncig tam sim no uas tau txais txiaj ntsig zoo dua. Thaum cov txheej txheem rov ua dua tshiab zoo dua qub, kev rov ua dua tshiab thiab rov siv dua ntawm cov ntim khoom hloov pauv yog qhov teeb meem.
