Txoj cai txhais lus |cov ntsiab lus koj yuav tsum paub txog EU "kev txwv txiav yas"
Tsis ntev los no, European Union txoj cai tswjfwm (tom qab no hu ua "txoj cai") rau bio-based, biodegradable thiab compostable plastics tau raug tso tawm.Txoj cai tseem ceeb txhawb nqa kev siv cov khoom siv rov ua dua tshiab thiab ib puag ncig zoo, uas yog coj mus rau yav tom ntej ntawm kev txhim kho ib puag ncig.Nws yuav tsis tsuas yog tswj hwm kev lag luam bioplastics zoo dua, thiab ua rau lub zog tshiab ntawm kev loj hlob hauv Tebchaws Europe kev lag luam bio-based thiab biodegradable plastics, tab sis kuj coj cov teeb meem kev tswj hwm tshiab ntawm bio-based thiab biodegradable plastics thiab compostable plastics.
Tig qhov nruj "kev txwv txiav yas", cov ntsiab lus twg tsim nyog khawb?Cia peb ua ib lub ntsiab lus rau koj kom nkag siab tob.
01 Lub tswv yim ntawm "bio-based, biodegradable thiab compostable plastics"?
"Bio-based" txhais tau hais tias cov khoom siv raw lossis cov khoom siv raw siv rau nws cov khoom yog ua los ntawm biomass, xws li qab zib, qoob loo cereal, roj qoob loo lossis ntoo thiab lwm yam tsis yog khoom noj.Lwm qhov chaw yog cov khoom pov tseg organic thiab cov khoom lag luam, xws li siv roj thiab bagasse.
Cov yas, lub npe hu ua "biodegradable", tau qhia meej meej kom decomposed los ntawm kev hloov tag nrho nws cov organic Cheebtsam (polymers thiab organic additives) rau hauv carbon dioxide thiab dej, tshiab microbial biomass, ntxhia ntsev thiab methane thaum tsis muaj oxygen thaum kawg. nws lub neej kev pab cuam los xyuas kom meej tias nws yog non-toxic thiab harmless rau ib puag ncig.
Raws li pom hauv daim duab saum toj no, nws tau muab faib ua plaub qhov loj: fossil-based, bio-based, biodegradable thiab non-biodegradable.
"Compostable plastics" yog ib feem ntawm biodegradable plastics, tsim los ua biodegradable nyob rau hauv kev tswj xyuas, feem ntau yog los ntawm industrial composting lossis anaerobic digestion hauv cov chaw tshwj xeeb.
Ib qho ntawm cov ntsiab lus tseem ceeb ntawm txoj cai tsim yog txhawm rau txheeb xyuas cov khoom siv bio-based, biodegradable thiab compostable plastics, thiab qhia cov xwm txheej los xyuas kom meej tias lawv cov khoom siv thiab kev siv tau zoo rau ib puag ncig.
BiONLY, ib zaj duab xis tshiab biodegradable ntawm nws tus kheej tsim los ntawm Xiamen Changsu, Nws muaj cov yam ntxwv ntawm bio-based thiab tswj tau degradation.Nws cov khoom siv raw PLA (polylactic acid) yog muab los ntawm cov hmoov txhuv nplej siab los ntawm pob kws thiab qab zib, uas yog fermented thiab polymerized los ntawm cov kab mob.Tom qab siv, cov khoom tuaj yeem degraded tag nrho rau hauv dej thiab carbon dioxide nyob rau hauv 8 lub lis piam nyob rau hauv industrial composting tej yam kev mob.
02 Yuav siv lo lus "bio-based, biodegradable thiab compostable plastics" li cas?
Rau "bio-based", lub sij hawm tsuas yog siv tau thaum qhia qhov tseeb thiab ntsuas qhov sib koom ntawm bio-based yas cov ntsiab lus hauv cov khoom, kom cov neeg siv khoom tuaj yeem paub ntau npaum li cas biomass tau siv hauv cov khoom.Tsis tas li ntawd, biomass siv yuav tsum yog los ntawm cov chaw ruaj khov thiab tsis ua rau muaj kev puas tsuaj rau ib puag ncig.
Rau "biodegradable", nws yuav tsum paub meej tias cov khoom zoo li no yuav tsum tsis txhob muab pov tseg thiab yuav tsum tau hais tias nws yuav siv sijhawm ntev npaum li cas rau cov khoom kom biodegrade, nyob rau hauv qhov xwm txheej thiab nyob rau hauv ib puag ncig (xws li av, dej, thiab lwm yam).Cov khoom uas zoo li yuav raug pov tseg, suav nrog cov hauv qab Txoj Cai Siv Ib Leeg Siv Plastics, tsis tuaj yeem thov lossis sau npe tias biodegradable.
Kuj tseem muaj cov kev cai meej rau "compostable plastics", ib qho ntawm cov kev faib tawm ntawm biodegradable plastics, uas tsuas yog cov khoom siv composting plastics uas ua tau raws li cov qauv tsim nyog yuav tsum tau sau npe tias "compostable" thiab cov ntim khoom siv compostable yuav tsum qhia tias cov khoom pov tseg li cas.Thiab muab tus cwj pwm ntawm cov neeg siv khoom, cov khoom siv compostable plastics yuav tsum tsuas yog siv rau cov ntawv thov tshwj xeeb yog tias lawv cov txiaj ntsig ib puag ncig ntau dua li ntawm lawv cov kev xaiv thiab tsis cuam tshuam qhov zoo ntawm compost.
Lub hom phiaj thib ob ntawm txoj cai tsim yog kom paub meej txog kev siv cov ntsiab lus tseem ceeb, uas tuaj yeem tswj tau zoo dua "bio-based, biodegradable thiab compostable plastics".
BiONLY® tsis tsuas yog muaj qib siab tshaj plaws ntawm biobase ntawv pov thawj tawm los ntawm DIN, European txoj cai ntawv pov thawj lub cev (biobase cov ntsiab lus ntawm ntau dua 85%), tab sis kuj muaj cov ntaub ntawv pov thawj kev lag luam compostable, cov khoom zoo kawg nkaus ua tau raws li cov kev xav tau ntawm cov neeg siv khoom xa tawm mus rau European. Union.
Nws tsim nyog hais tias nyob rau tib hnub, European Commission tau tshaj tawm tsab ntawv pom zoo los hloov kho Cov Lus Qhia Ntim thiab Ntim Cov Khoom Siv Khib Nyiab (PPWD), uas tau lees paub qhov kev koom tes ntawm cov khoom siv yas hauv kev ua kom muaj nuj nqis thiab zoo ntawm cais cov khib nyiab pov tseg thiab txo cov pa phem. ntawm (organic) cov kwj deg.Nws kuj yuav tsum tau hais tias lub hnab tshuaj yej los yog lim kas fes hnab, tshuaj ntsiav, lub hnab yas lub teeb heev thiab cov ntawv nplaum uas muaj rau cov txiv hmab txiv ntoo thiab zaub yuav tsum yog compostable.Nyob rau tib lub sijhawm, Pawg Neeg Saib Xyuas tseem muaj txoj cai nthuav dav cov npe ntawm cov ntawv thov rau kev siv cov ntim ntim compostable, uas undoubtedly qhib rau yav tom ntej qhov chaw rau daim ntawv thov ntawm compostable plastics nyob rau hauv lub EU.
03 Dab tsi yog cov kev cai tshwj xeeb rau cov khoom xa tawm tom qab tsim txoj cai?
Hauv cov ntsiab lus ntawm cov pa roj carbon tsawg thiab kev tiv thaiv ib puag ncig, kev ua tiav lub hom phiaj ntawm "carbon neutrality" tau dhau los ua qhov kev pom zoo ntawm cov zej zog thoob ntiaj teb.Kev nrawm ntawm kev tsim kho ntsuab thiab qis-carbon txoj kev loj hlob tau dhau los ua qhov sib txawv ntawm lub sijhawm.Kev tshaj tawm txoj cai tshiab EU yog undoubtedly cov pov thawj zoo tshaj plaws.Lub tswv yim ntawm txoj cai no tseem qhia tau hais tias European Commission txoj kev hloov pauv mus rau kev rov ua dua tshiab, kev siv peev txheej thiab kev lag luam huab cua tsis zoo, nrog rau nws txoj kev txiav txim siab kom ua tiav qhov tsis muaj kuab paug.Nws tuaj yeem pom tau tias rau cov khoom xa tawm mus rau EU yav tom ntej, cov ntawv pov thawj muaj feem cuam tshuam yog qhov tsis txaus ntseeg ntawm txhua yam.
Xiamen Changshu txaus siab ua haujlwm nrog cov neeg ua lag luam hauv qab los sib koom ua ke ua tiav lub luag haujlwm ntawm cov pa roj carbon tsawg, thiab ua haujlwm nrog ntau lub tuam txhab zoo hauv Suav teb los pab cov neeg siv khoom thoob ntiaj teb nrog cov khoom zoo, tsim kom muaj txiaj ntsig ntau dua thiab mus rau lub ntiaj teb theem.
