Los ntawm 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 lub neej txhua hnub vim lawv lub teeb yuag, durability, kev zoo nkauj, thiab tus nqi qis.Txawm li cas los xij, nws yog qhov tseeb ntawm qhov zoo ntawm cov yas uas tseem ua rau muaj ntau cov khoom pov tseg 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 lub zog thiab tshuaj lom neeg kev lag luam kom txav mus rau "carbon neutrality".
Post-consumer recycled (PCR) resins yog tsim los ntawm cov khoom pov tseg yas pov tseg los ntawm cov neeg siv khoom.Cov yas pellets tshiab yog tsim los ntawm kev sau cov khoom pov tseg los ntawm cov kwj deg rov ua dua tshiab thiab dhau los ntawm kev txheeb xyuas, tu, thiab pelletizing txheej txheem ntawm cov txheej txheem rov ua dua tshiab.Cov yas pellets tshiab muaj cov qauv zoo ib yam li cov yas ua ntej rov ua dua tshiab.Thaum cov yas pellets tshiab sib xyaw nrog cov khoom siv nkauj xwb, ntau yam khoom siv yas tshiab tau tsim.Txoj kev no, tsis tsuas yog txo cov pa roj carbon dioxide emissions, tab sis kuj txo lub zog noj.
—— Dow tau tshaj tawm cov ntaub ntawv uas muaj 40% PCR cob
Xyoo 2020, Dow (DOW) tau tsim thiab ua lag luam ib qho tshiab tom qab cov neeg siv khoom siv rov ua dua tshiab (PCR) tsim cov resin tsim los rau cov ntawv siv cua sov hauv cheeb tsam Asia Pacific.Cov resin tshiab muaj 40% tom qab cov neeg siv khoom siv rov ua dua tshiab thiab tuaj yeem tsim cov yeeb yaj kiab nrog cov khoom zoo ib yam li cov pob zeb nkauj xwb.Cov resin tuaj yeem yog 100% siv nyob rau hauv nruab nrab txheej ntawm cov cua sov shrinkable zaj duab xis, yog li cov ntsiab lus ntawm cov khoom siv rov ua dua nyob rau hauv tag nrho cov qauv shrinkable zaj duab xis tuaj yeem ncav cuag 13% ~ 24%.
Dow's tshiab tom qab cov neeg siv khoom siv rov ua dua tshiab (PCR) cov khoom siv ua kom muaj qhov zoo shrinkage, robustness thiab durability.Nrog rau kev thov loj hlob rau kev lag luam e-lag luam, ruaj khov, ntim tau zoo tuaj yeem tiv thaiv cov khoom thoob plaws hauv cov khoom siv thiab txo cov khoom pov tseg rau cov neeg siv khoom.
Cov khoom siv PCR no tau tsim los rau daim ntawv thov ntawm cov cua sov shrinkable zaj duab xis muab kev lees paub rau pawg ntim thiab kev thauj mus los nyab xeeb hauv kev lag luam ntim nrog zoo shrinkage tus nqi, ruaj khov machining thiab zoo txhua yam khoom.
Tsis tas li ntawd, cov tshuaj muaj 40% tom qab cov neeg siv khoom siv cov ntaub ntawv rov qab, uas tuaj yeem siv rau hauv nruab nrab txheej ntawm cov cua sov shrinkable films, uas tuaj yeem txo cov pa roj carbon dioxide emissions thiab lub zog noj thaum lub sij hawm tsim cov resin thiab ua tiav lub hom phiaj ntawm kev rov ua dua zaj duab xis.
Txij li xyoo 2019, lub ntiaj teb cov lus teb rau cov pa phem yas tau raug tsim tawm, thiab cov tuam txhab thov yas tau cog lus tias yuav nthuav dav kev siv cov yas rov ua dua tshiab lossis kom tsis txhob siv cov yas siv.Lub hom phiaj tau teeb tsa los ntawm Circular Plastics Alliance yog txhawm rau ua kom cov yas rov ua dua tshiab ntawm EU ua lag luam rau 10 lab metric tons los ntawm 2025. Petrochemical giants xws li Dow, Total Borealis, INEOS, SABIC, Eastman, thiab Covestro yog tag nrho cov kev txav loj. nyob rau hauv kev lag luam plastics recycled.
—— Nyiv Nagase launched PET chemical recycling PCR technology
PCR feem ntau ntawm kev ua lag luam yog kev siv lub cev, tab sis lub cev rov ua dua tshiab muaj qhov tsis zoo, xws li kev poob ntawm cov khoom siv, kev txwv ntawm kev siv xim, thiab tsis muaj peev xwm muab zaub mov qib.Txawm li cas los xij, nrog rau kev txhim kho thev naus laus zis, tshuaj rov qab PCR muab kev xaiv ntau dua thiab zoo dua rau kev ua lag luam, tshwj xeeb tshaj yog rau cov ntawv thov kev lag luam siab.
Qhov zoo ntawm kev rov ua dua tshiab ntawm PCR suav nrog: qhov zoo ib yam thiab cov yam ntxwv ntawm cov khoom qub;ruaj khov lub cev;tsis xav tau pwm thiab tshuab;Kev hloov pauv parameter, siv ncaj qha;xim txuam daim ntaub ntawv;tuaj yeem ua raws li REACH, RoHS, EPEAT cov qauv;muab cov khoom noj khoom haus qib, thiab lwm yam.
—— Lub ntim ntawm tag nrho cov txheej txheem tu plaub hau ntawm L'Oreal Tuam Tshoj ua lag luam tau ua los ntawm 100% PCR yas
L'Oréal Group tau tshaj tawm cov tiam tshiab ntawm 2030 lub hom phiaj kev txhim kho kom ruaj khov "L'O éal rau yav tom ntej", lub hom phiaj lub tswv yim no yog ua raws li peb tus ncej: kev hloov pauv tus kheej nrog kev hwm rau thaj tsam ntawm lub ntiaj teb;txhawb kev lag luam ecosystems;Pab txhawb rau kev tsim "dual-engine" qauv uas ua rau kom muaj kev hloov pauv sab hauv thiab txhawb nqa lub ecosystem sab nraud.
L'Oreal tau npaj xya txoj cai los txo cov pa hluav taws xob hauv tsev cog khoom rau ib chav tsev ntawm 50% los ntawm 2030 piv nrog rau xyoo 2016;los ntawm 2025, tag nrho cov chaw khiav hauj lwm yuav txhim kho lub zog efficiency, siv 100% lub zog tauj dua tshiab, thiab tom qab ntawd ua tiav cov pa roj carbon nruab nrab;Los ntawm 2030, los ntawm kev tsim kho tshiab, cov neeg siv khoom yuav txo cov roj tsev cog khoom tsim los ntawm kev siv peb cov khoom los ntawm 25% ib chav tsev ntawm cov khoom tiav piv rau xyoo 2016;los ntawm 2030, 100% ntawm cov dej hauv cov txheej txheem kev lag luam yuav raug siv dua;los ntawm 2030, 95% ntawm cov khoom xyaw hauv formulations yuav yog bio-based, tau los ntawm ntau cov zaub mov lossis cov txheej txheem rov ua dua tshiab;los ntawm 2030, 100% ntawm cov yas hauv cov khoom ntim yuav tau txais los ntawm cov khoom siv rov ua dua lossis cov khoom siv bio-raws li (txog Xyoo 2025, 50% yuav ncav cuag).
Qhov tseeb, kev ua cuam tshuam txog "kev hwm thaj tsam ntawm lub ntiaj teb" twb tau muab coj los ua.Los ntawm kev xav ntawm Suav lag luam, lub ntim ntawm L'Oreal Paris cov plaub hau tu series yog twb ua los ntawm 100% PCR yas;Tsis tas li ntawd, L'Oreal tau tsim cov kev daws teeb meem tshiab, siv cov khoom siv rov ua dua lossis rov ua dua tshiab kom tsis txhob siv cov ntim ib zaug.
Nws yog ib qho tsim nyog hais tias, ntxiv rau L'Oreal tus kheej cov khoom ntim khoom, cov pab pawg kuj tau dhau los ntawm lub tswv yim ntim khoom zoo li no rau lwm cov channel.Cov txheej txheem kev ntim khoom tshiab ntawm "pob ntsuab" tau pib ua haujlwm nrog Tmall yog ib qho piv txwv tseem ceeb.Thaum lub Kaum Ib Hlis 2018, cov pab pawg tau koom tes nrog Tmall los tsim cov txheej txheem ntim khoom tshiab hu ua "pob ntsuab" rau nws cov khoom kim heev;Hauv 2019, L'Oreal nthuav dav "pob ntsuab" rau ntau lub npe, nrog rau tag nrho txog 20 lab xa khoom A "pob ntsuab".
Somewang ntau yam khoom PCR yog rau koj siv.
