Kupyolera mu kuyesetsa kosalekeza kwa mibadwo ingapo ya akatswiri a zamankhwala ndi mainjiniya, mapulasitiki opangidwa kuchokera ku petroleum, malasha, ndi gasi achilengedwe akhala zida zofunika kwambiri pamoyo watsiku ndi tsiku chifukwa cha kulemera kwake, kulimba, kukongola, ndi mtengo wotsika.Komabe, ndizo zabwino izi za pulasitiki zomwe zimadzetsanso zinyalala zambiri zapulasitiki.Pulasitiki ya Post-consumer recycling (PCR) yakhala imodzi mwa njira zofunika kwambiri zochepetsera kuwonongeka kwa chilengedwe cha pulasitiki ndikuthandizira makampani opanga mphamvu ndi mankhwala kuti apite ku "kusalowerera ndale kwa carbon".
Ma resins a Post-consumer recycled (PCR) amapangidwa kuchokera ku zinyalala zapulasitiki zomwe zimatayidwa ndi ogula.Mapulastiki atsopano amapangidwa potolera zinyalala za pulasitiki kuchokera mumtsinje wobwezeretsanso ndikudutsa posankha, kuyeretsa, ndi kupanga ma pelleting a makina obwezeretsanso.Ma pellets atsopano apulasitiki amakhala ndi mawonekedwe ofanana ndi apulasitiki asanabwezeretsedwe.Pamene mapepala apulasitiki atsopano amasakanikirana ndi utomoni wa namwali, mitundu yosiyanasiyana ya pulasitiki yatsopano imapangidwa.Mwanjira iyi, sikuti amachepetsa mpweya woipa wa carbon dioxide, komanso amachepetsa mphamvu zamagetsi.
——Dow yakhazikitsa zida zomwe zili ndi 40% PCR resin
Mu 2020, Dow (DOW) idapanga ndikugulitsa utomoni wopangidwa ndi post-consumer recycled (PCR) wopangidwira mafilimu ochepetsa kutentha ku Asia Pacific.Utomoni watsopanowu uli ndi 40% zobwezerezedwanso pambuyo pa ogula ndipo zimatha kupanga mafilimu okhala ndi zinthu zofanana ndi utomoni wa namwali.The utomoni akhoza 100% ntchito pakati wosanjikiza kutentha shrinkable filimu, kotero kuti zili zinthu zobwezerezedwanso mu lonse shrinkable dongosolo filimu akhoza kufika 13% ~ 24%.
Dow's post-consumer recycled resin (PCR) yopangidwa ndi utomoni watsopano umapereka kuchepa kwabwino, kulimba komanso kulimba.Ndi kufunikira kokulirapo kwa e-commerce, kuyika kokhazikika, koyenera kumatha kuteteza zinthu pazogulitsa ndikuchepetsa zinyalala kwa ogula.
Izi za PCR resin zopangidwira kuti zigwiritsidwe ntchito filimu yowotcha kutentha zimapereka chitsimikizo cha kulongedza masango ndi mayendedwe otetezeka m'makampani olongedza katundu ndi kuchuluka kwabwino kwa shrinkage, makina okhazikika komanso makina abwino kwambiri.
Kuphatikiza apo, yankholi lili ndi 40% ya zinthu zobwezerezedwanso pambuyo pa ogula, zomwe zitha kugwiritsidwa ntchito pakati pa mafilimu otenthetsera kutentha, omwe amatha kuchepetsa kutulutsa kwa carbon dioxide ndi kugwiritsa ntchito mphamvu panthawi yopanga utomoni ndikukwaniritsa cholinga chobwezeretsanso filimu.
Kuyambira mchaka cha 2019, kuyankha kwapadziko lonse pazowononga pulasitiki kwakhazikitsidwa, ndipo makampani opanga mapulasitiki alonjeza kuti akulitsa kwambiri kugwiritsa ntchito mapulasitiki obwezeretsedwanso kapena kuchepetsa pulasitiki yomwe imagwiritsidwa ntchito.Cholinga chokhazikitsidwa ndi Circular Plastics Alliance ndi kuonjezera kuchuluka kwa pulasitiki yokonzedwanso pamsika wa EU kufika ku 10 miliyoni metric tons pofika 2025. Zimphona zazikulu za Petrochemical monga Dow, Total Borealis, INEOS, SABIC, Eastman, ndi Covestro zonse zikuyenda bwino. m'makampani apulasitiki obwezerezedwanso.
——Japan Nagase yakhazikitsa ukadaulo wa PET chemical recycling PCR
PCR yambiri pamsika ndi yobwezeretsanso thupi, koma kubwezeretsanso thupi kumakhala ndi zofooka, monga kuchepa kwa zinthu zamakina, kuchepetsa kugwiritsa ntchito mitundu, komanso kulephera kupereka chakudya.Komabe, ndi chitukuko chaukadaulo, kuchira kwamankhwala PCR kumapereka zosankha zambiri pamsika, makamaka pazogulitsa zamsika zapamwamba.
Ubwino wa PCR yobwezeretsanso mankhwala ndi monga: mtundu womwewo ndi mawonekedwe azinthu zoyambirira;zokhazikika zakuthupi;palibe kufunikira kwa nkhungu ndi makina;kusinthidwa kwa parameter, kugwiritsa ntchito mwachindunji;mitundu yofananira ntchito;akhoza kutsatira REACH, RoHS, EPEAT miyezo;kupereka zinthu zamagulu a chakudya, etc.
——Kupaka mndandanda wathunthu wazosamalira tsitsi pamsika wa L'Oreal China wapangidwa ndi pulasitiki ya 100% PCR
Gulu la L'Oréal lakonza mbadwo watsopano wa zolinga zachitukuko zokhazikika za 2030 "L'O éal for the future", cholinga ichi chimachokera pazipilala zitatu: kudzisintha ndikulemekeza malire a dziko lapansi;kulimbikitsa chilengedwe cha bizinesi;Thandizani kupanga "injini ziwiri" zomwe zimafulumizitsa kusintha mkati ndikupatsa mphamvu zachilengedwe kunja.
L'Oreal inapereka malamulo asanu ndi awiri ochepetsera mpweya wowonjezera kutentha pa gawo lililonse la mankhwala ndi 50% pofika 2030 poyerekeza ndi 2016;pofika chaka cha 2025, malo onse ogwiritsira ntchito adzapititsa patsogolo mphamvu zamagetsi, kugwiritsa ntchito mphamvu zowonjezera 100%, ndikukwaniritsa kusalowerera ndale kwa carbon;Pofika chaka cha 2030, pogwiritsa ntchito zatsopano, ogula adzachepetsa mpweya wowonjezera kutentha wopangidwa ndi kugwiritsa ntchito mankhwala athu ndi 25% pa gawo lililonse la mankhwala omalizidwa poyerekeza ndi 2016;pofika chaka cha 2030, 100% ya madzi m'mafakitale adzakonzedwanso Gwiritsani ntchito;pofika chaka cha 2030, 95% ya zosakaniza zomwe zimapangidwira zidzakhala zochokera kuzinthu zachilengedwe, zochokera ku mchere wochuluka kapena njira zobwezeretsedwa;pofika chaka cha 2030, 100% ya pulasitiki muzoyikapo idzachotsedwa kuchokera kuzinthu zobwezerezedwanso kapena zochokera pazachilengedwe (mpaka mu 2025, 50% idzafikiridwa).
Ndipotu, zochita zokhudzana ndi "kulemekeza malire a dziko lapansi" zakhala zikugwiritsidwa ntchito kale.Kuchokera pakuwona msika waku China, kulongedza kwa gulu losamalira tsitsi la L'Oreal Paris kumapangidwa kale ndi pulasitiki ya 100% PCR;Kuphatikiza apo, L'Oreal yapanga njira zopangira zida zatsopano, pogwiritsa ntchito njira zowonjezeretsanso kapena kubwezeretsanso kuti mupewe kuyika kamodzi kokha.
Ndikoyenera kutchula kuti, kuphatikiza pakupanga kwa L'Oreal, gululi laperekanso lingaliro losunga zachilengedwe kumayendedwe ena.Mulingo watsopano wa "gulu lobiriwira" lokhazikitsidwa mogwirizana ndi Tmall ndi chitsanzo chofunikira.Mu Novembala 2018, gululi lidagwirizana ndi Tmall kuti akhazikitse mulingo watsopano wonyamula katundu wotchedwa "green package" wamtundu wake wapamwamba;mu 2019, L'Oreal adakulitsa "phukusi lobiriwira" kuzinthu zambiri, ndipo pafupifupi 20 miliyoni adatumizidwa "Phukusi lobiriwira".
