Dab tsi yog cov khoom siv PCR?
1. Cov ntaub ntawv PCR yog dab tsi?
Cov khoom siv PCR tiag tiag yog ib hom "cov yas rov ua dua tshiab", lub npe tag nrho yog cov khoom siv rov qab siv dua tshiab, uas yog, cov khoom siv rov qab siv dua.
Cov ntaub ntawv PCR yog "muaj txiaj ntsig heev".Feem ntau, cov khoom pov tseg uas tsim los tom qab kev ncig, kev siv thiab siv tau tuaj yeem hloov mus rau hauv cov khoom lag luam muaj txiaj ntsig zoo heev los ntawm kev rov ua dua tshiab los yog siv tshuaj lom neeg rov ua dua tshiab, ua kom muaj peev xwm rov tsim dua tshiab thiab rov ua dua tshiab.
Piv txwv li, cov khoom siv rov ua dua tshiab xws li PET, PE, PP, thiab HDPE tuaj ntawm cov khoom pov tseg uas tau tsim los ntawm cov thawv ntim khoom noj uas nquag siv, cov tshuaj zawv plaub hau, lub raj mis dej ntxhia, lub tshuab ntxhua khaub ncaws, thiab lwm yam. cov khoom ntim..
Txij li cov ntaub ntawv PCR los ntawm cov khoom siv tom qab siv, yog tias lawv tsis ua tiav, lawv yuav muaj kev cuam tshuam ncaj qha rau ib puag ncig.Yog li, PCR yog ib qho ntawm cov khoom siv rov ua dua tshiab tam sim no pom zoo los ntawm ntau lub npe.
2. Vim li cas cov yas PCR thiaj li nrov?
•(1).PCR yas yog ib qho ntawm cov lus qhia tseem ceeb los txo cov pa phem yas thiab ua rau "carbon neutrality".
Tom qab kev siv zog tsis tu ncua ntawm ntau tiam neeg ntawm chemists thiab engineers, plastics uas tsim los ntawm roj av, thee, thiab natural gas tau dhau los ua cov ntaub ntawv tseem ceeb rau tib neeg lub neej vim lawv lub cev nyhav, ruaj khov, thiab kev zoo nkauj.Txawm li cas los xij, kev siv ntau ntawm cov yas kuj tau ua rau cov khoom pov tseg ntau ntawm cov yas.Post-consumer recycling (PCR) yas tau dhau los ua ib qho ntawm cov lus qhia tseem ceeb los txo cov pa phem ib puag ncig thiab pab kev lag luam tshuaj mus rau "carbon neutrality".
Cov yas pellets rov ua dua yog sib xyaw nrog cov pob zeb nkauj xwb los tsim ntau yam khoom siv yas tshiab.Txoj kev no tsis tsuas yog txo cov pa roj carbon dioxide emissions, tab sis kuj txo lub zog noj.
•(2).Siv cov yas PCR los txhawb kev siv cov yas pov tseg
Ntau lub tuam txhab uas siv PCR plastics, qhov xav tau ntau dua, uas yuav ua rau kom rov ua dua cov khoom pov tseg thiab maj mam hloov cov qauv thiab kev ua lag luam ntawm cov khoom siv pov tseg pov tseg, txhais tau tias cov khoom pov tseg tsawg dua yuav raug pov tseg, incinerated thiab khaws cia rau hauv ib puag ncig.nyob rau hauv ib puag ncig ntuj.
• (3).Txoj cai nce qib
Txoj cai qhov chaw rau PCR yas yog qhib.
Siv cov teb chaws Europe ua piv txwv, EU plastics lub tswv yim thiab cov yas thiab ntim cov cai lij choj hauv cov tebchaws xws li Tebchaws Askiv thiab Lub Tebchaws Yelemees.Piv txwv li, UK Cov Nyiaj Tau Los thiab Kev lis kev cai tau tshaj tawm "Plastic Ntim Tax".Tus nqi se rau ntim nrog tsawg dua 30% cov yas rov ua dua tshiab yog 200 phaus ib tuj.Kev sau se thiab cov cai tau qhib qhov chaw thov rau PCR plastics.
3. Cov tuam txhab lag luam twg tau nce lawv cov peev txheej hauv PCR yas tsis ntev los no?
Tam sim no, feem ntau ntawm cov khoom siv yas PCR ntawm kev ua lag luam tseem ua raws li kev siv lub cev rov ua dua tshiab.Ntau thiab ntau cov kev lag luam tshuaj lom neeg thoob ntiaj teb tau ua raws li kev txhim kho thiab kev siv tshuaj siv tshuaj PCR cov khoom siv yas.Lawv vam tias yuav xyuas kom meej tias cov khoom siv rov ua dua tshiab muaj qhov ua tau zoo ib yam li cov khoom siv raw., thiab tuaj yeem ua tiav "kev txo qis".
•(1).BASF's Ultramid recycled khoom tau txais UL ntawv pov thawj
BASF tshaj tawm lub lim tiam no tias nws cov Ultramid Ccycled rov siv cov polymer uas tsim los ntawm nws Freeport, Texas, cog tau txais ntawv pov thawj los ntawm Underwriters Laboratories (UL).
Raws li UL 2809, Ultramid Ccycled polymers rov siv dua los ntawm cov khoom siv tom qab siv dua (PCR) tuaj yeem siv cov txheej txheem sib npaug kom tau raws li cov qauv siv rov ua dua tshiab.Cov qib polymer muaj cov khoom zoo ib yam li cov khoom siv raw thiab tsis tas yuav hloov kho rau cov txheej txheem ua haujlwm ib txwm muaj.Nws tuaj yeem siv rau hauv cov ntawv thov xws li ntim cov yeeb yaj kiab, cov ntaub pua plag thiab rooj tog zaum, thiab yog ib txoj hauv kev ruaj khov rau cov khoom siv raw.
BASF tab tom tshawb nrhiav cov txheej txheem tshuaj tshiab los txuas ntxiv hloov qee cov khoom pov tseg rau hauv cov khoom siv tshiab, muaj txiaj ntsig zoo.Txoj hauv kev no txo qis cov pa hluav taws xob hauv tsev cog khoom thiab cov khoom siv fossil raw khoom thaum tswj cov khoom zoo thiab kev ua haujlwm.
Randall Hulvey, BASF North American Business Director:
“Peb cov qib Ultramid Ccycled tshiab muaj tib lub zog txhua yam, nruj thiab thermal stability raws li cov qib ib txwm muaj, ntxiv rau nws yuav pab peb cov neeg siv khoom ua tiav lawv cov hom phiaj ruaj khov.”
•(2).Mengniu: Thov Dow PCR cob
Thaum Lub Rau Hli 11, Dow thiab Mengniu koom ua ke tshaj tawm tias lawv tau ua tiav kev lag luam tom qab cov neeg siv khoom siv rov ua dua cov khoom siv cua sov shrinkable zaj duab xis.
Nws tau nkag siab tias qhov no yog thawj zaug hauv kev lag luam khoom noj khoom haus hauv tsev uas Mengniu tau koom ua ke nws cov khoom lag luam ecological thiab koom ua ke nrog cov khoom siv yas raw khoom, ntim khoom, cov khoom siv rov ua dua tshiab thiab lwm yam kev lag luam saw tog kom paub txog kev rov ua dua thiab rov siv cov ntim yas, tag nrho. thov cov neeg siv khoom siv rov qab siv cov yas ua cov khoom ntim zaj duab xis.
Cov txheej txheem nruab nrab ntawm cov khoom ntim thib ob thaum tshav kub kub shrinkable zaj duab xis siv los ntawm Mengniu cov khoom los ntawm Dow's PCR resin formula.Cov mis no muaj 40% cov khoom siv tom qab cov neeg siv khoom siv dua tshiab thiab tuaj yeem nqa cov khoom siv rov ua dua tshiab nyob rau hauv tag nrho cov shrink zaj duab xis qauv mus rau 13% -24%, ua rau kev tsim cov yeeb yaj kiab nrog kev ua tau zoo piv rau nkauj xwb.Nyob rau tib lub sijhawm, nws txo qis cov khoom pov tseg yas hauv ib puag ncig thiab ua tiav qhov kev kaw-voj daim ntawv thov kev ntim khoom rov ua dua tshiab.
•(3).Unilever: Hloov mus rau rPET rau nws cov khoom noj khoom haus, dhau los ua UK's thawj 100% PCR zaub mov hom
Thaum lub Tsib Hlis, Unilever's condiment brand Hellmann's switched to 100% post-consumer recycled PET (rPET) and launched it in the UK.Unilever tau hais tias yog tias tag nrho cov koob no tau hloov nrog rPET, nws yuav txuag tau li ntawm 1,480 tons ntawm raw khoom txhua xyoo.
Tam sim no, ze li ntawm ib nrab (40%) ntawm Hellmann cov khoom twb siv cov yas rov ua dua tshiab thiab ntaus cov txee rau lub Tsib Hlis.Lub tuam txhab npaj yuav hloov mus rau cov yas rov ua dua tshiab rau cov khoom lag luam no thaum kawg ntawm 2022.
Andre Burger, tus lwm thawj ntawm cov zaub mov ntawm Unilever UK thiab Ireland, tau hais tias:“Peb Hellmann's condiment fwj yog peb cov khoom noj thawj zaug hauv UK los siv 100% tom qab cov neeg siv khoom siv yas, txawm hais tias nyob rau hauv qhov kev hloov no tau muaj kev sib tw, tab sis qhov kev paub yuav ua rau peb txhawm rau txhawm rau siv cov yas siv dua tshiab thoob plaws Unilever.'s lwm hom zaub mov.”
PCR tau dhau los ua daim ntawv lo rauECO-cov ntaub ntawv phooj ywg.Ntau lub tebchaws nyob sab Europe tau siv PCR rau kev ntim khoom noj kom ntseeg tau 100%ECO-phooj ywg.
Peb yog cov chaw tsim khoom tshwj xeeb hauv kev tsim cov hnab ntim kas fes rau ntau tshaj 20 xyoo.Peb tau dhau los ua ib lub hnab kas fes loj tshaj plaws hauv Suav teb.
Peb siv qhov zoo tshaj plaws WIPF li qub los ntawm Swiss kom koj kas fes tshiab.
Peb tau tsim lub eco-phooj ywg hnab, xws li cov hnab compostable thiab recyclable hnab,thiab cov ntaub ntawv PCR tshiab tshaj tawm.
Lawv yog cov kev xaiv zoo tshaj plaws los hloov cov hnab yas pa.
Txuas nrog peb cov catalogue, thov xa peb lub hnab hom, khoom siv, qhov loj thiab ntau npaum li cas koj xav tau.Yog li peb tuaj yeem hais koj.
