Kodi zinthu za PCR ndi chiyani kwenikweni?
1. Kodi zinthu za PCR ndi chiyani?
PCR kwenikweni ndi mtundu wa "pulasitiki wobwezerezedwanso", dzina lonse ndi Post-Consumer Recycled material, ndiye kuti, zinthu zobwezerezedwanso pambuyo pa ogula.
Zida za PCR "ndizofunika kwambiri".Nthawi zambiri, zinyalala mapulasitiki opangidwa pambuyo kufalitsidwa, kugwiritsidwa ntchito ndi kugwiritsidwa ntchito kumatha kusinthidwa kukhala zida zamtengo wapatali zopangira mafakitale kudzera pakubwezeretsanso kapena kukonzanso mankhwala, kuzindikira kukonzanso kwazinthu ndikubwezeretsanso.
Mwachitsanzo, zinthu zobwezerezedwanso monga PET, PE, PP, ndi HDPE zimachokera ku zinyalala zamapulasitiki opangidwa kuchokera m'mabokosi a chakudya chamasana omwe amagwiritsidwa ntchito nthawi zambiri, mabotolo a shampoo, mabotolo am'madzi amchere, migolo yamakina ochapira, ndi zina. Pambuyo pokonzanso, amatha kugwiritsidwa ntchito kupanga zatsopano. zonyamula katundu..
Popeza kuti zinthu za PCR zimachokera ku zinthu zomwe zimagwiritsidwa ntchito pambuyo pa ogula, ngati sizikukonzedwa bwino, mosakayikira zidzakhudza kwambiri chilengedwe.Chifukwa chake, PCR ndi imodzi mwamapulasitiki obwezerezedwanso omwe amalimbikitsidwa ndi mitundu yosiyanasiyana.
2. Chifukwa chiyani mapulasitiki a PCR ali otchuka kwambiri?
•(1).Pulasitiki ya PCR ndi imodzi mwa njira zofunika kwambiri zochepetsera kuipitsidwa kwa pulasitiki ndikuthandizira "kusalowerera ndale kwa kaboni".
Pambuyo pa khama losalekeza la mibadwo ingapo ya akatswiri a zamankhwala ndi mainjiniya, mapulasitiki opangidwa kuchokera ku petroleum, malasha, ndi gasi achilengedwe akhala zinthu zofunika kwambiri pa moyo wa munthu chifukwa cha kulemera kwake, kulimba, ndi kukongola kwake.Komabe, kugwiritsa ntchito kwambiri mapulasitiki kwapangitsanso kutulutsa zinyalala zambiri zapulasitiki.Pulasitiki ya Post-consumer recycling (PCR) yakhala imodzi mwa njira zofunika kwambiri zochepetsera kuwonongeka kwa chilengedwe cha pulasitiki ndikuthandizira makampani opanga mankhwala kuti apite ku "kusalowerera ndale kwa carbon".
Ma pellets apulasitiki obwezerezedwanso amasakanizidwa ndi utomoni wa namwali kuti apange zinthu zapulasitiki zatsopano.Njirayi sikuti imangochepetsa mpweya woipa wa carbon dioxide, komanso imachepetsanso mphamvu zamagetsi.
•(2).Gwiritsani ntchito pulasitiki ya PCR kuti mupititse patsogolo kubweza pulasitiki zinyalala
Makampani ochulukirapo omwe amagwiritsa ntchito mapulasitiki a PCR, kufunikira kwakukulu, komwe kudzawonjezera kubwezeretsedwa kwa mapulasitiki a zinyalala ndikusintha pang'onopang'ono machitidwe ndi ntchito zamabizinesi obwezeretsanso zinyalala za pulasitiki, kutanthauza kuti mapulasitiki ochepa azinyalala adzatayidwa, kuwotchedwa ndikusungidwa m'chilengedwe.m'malo achilengedwe.
• (3).Kukwezeleza ndondomeko
Malo a mfundo zamapulasitiki a PCR akutseguka.
Tengani Europe mwachitsanzo, njira zamapulasitiki za EU ndi malamulo amisonkho apulasitiki ndi ma phukusi m'maiko monga Britain ndi Germany.Mwachitsanzo, UK Revenue and Customs yatulutsa "Msonkho Wopaka Pulasitiki".Misonkho yonyamula ndi pulasitiki yosakwana 30% yobwezeretsanso ndi mapaundi 200 pa tani.Misonkho ndi ndondomeko zatsegula malo ofunikira a mapulasitiki a PCR.
3. Ndi zimphona ziti zamakampani zomwe zikuwonjezera ndalama zawo mu mapulasitiki a PCR posachedwa?
Pakadali pano, zinthu zambiri zamapulasitiki za PCR pamsika zimakhazikika pakubwezeretsanso thupi.Mafakitale ochulukirachulukira padziko lonse lapansi akutsatira kakulidwe ndi kugwiritsa ntchito zinthu zapulasitiki za PCR zokonzedwanso ndi mankhwala.Iwo akuyembekeza kuonetsetsa kuti zinthu zobwezerezedwanso zimagwira ntchito mofanana ndi zopangira., ndipo akhoza kukwaniritsa "kuchepetsa mpweya".
•(1).Mtengo wa BASF's Ultramid zobwezerezedwanso zakuthupi amapeza UL certification
BASF idalengeza sabata ino kuti polima yake ya Ultramid Ccycled yopangidwanso ku Freeport, Texas, yalandila ziphaso kuchokera ku Underwriters Laboratories (UL).
Malinga ndi UL 2809, ma polima a Ultramid Ccycled opangidwanso kuchokera ku mapulasitiki opangidwanso ndi ogula (PCR) amatha kugwiritsa ntchito masinthidwe ambiri kuti akwaniritse zomwe zasinthidwanso.Gulu la polima lili ndi zinthu zofanana ndi zopangira ndipo sizifunikira kusintha kwa njira zachikhalidwe.Itha kugwiritsidwa ntchito pazinthu monga kulongedza mafilimu, makapeti ndi mipando, ndipo ndi njira yokhazikika yopangira zinthu zopangira.
BASF ikufufuza njira zatsopano zamakina kuti ipitilize kusandutsa zinyalala zina kukhala zida zatsopano zamtengo wapatali.Njirayi imachepetsa kutulutsa mpweya wowonjezera kutentha komanso zopangira zopangira zinthu zakale ndikusunga zinthu zabwino komanso magwiridwe antchito.
Randall Hulvey, BASF North America Business Director:
“Gulu lathu latsopano la Ultramid Ccycled limapereka mphamvu zofananira zamakina, kuuma komanso kukhazikika kwamafuta monga magiredi achikhalidwe, kuphatikiza izi zithandizira makasitomala athu kukwaniritsa zolinga zawo zokhazikika.”
•(2).Mengniu: Ikani Dow PCR resin
Pa June 11, Dow ndi Mengniu pamodzi adalengeza kuti agulitsa bwino filimu yotenthetsera ya resin yosinthidwa ndi ogula.
Zikumveka kuti aka ndi nthawi yoyamba mu makampani chakudya zoweta kuti Mengniu Integrated mphamvu zake mafakitale zachilengedwe ndi ogwirizana ndi pulasitiki zopangira katundu, opanga ma CD, recyclers ndi zina makampani unyolo maphwando kuzindikira yobwezeretsanso ndi kugwiritsanso ntchito ma CD mapulasitiki, mokwanira. kugwiritsa ntchito mapulasitiki opangidwanso pambuyo pa ogula ngati filimu yonyamula katundu.
Wosanjikiza wapakati wa filimu yachiwiri yotenthetsera kutentha yomwe imagwiritsidwa ntchito ndi zinthu za Mengniu zimachokera ku Dow's PCR resin formula.Fomula ili ndi 40% zobwezerezedwanso pambuyo pa ogula ndipo zitha kubweretsa zomwe zidabwezerezedwanso mufilimu yonse yocheperako kufika 13% -24%, zomwe zimathandizira kupanga mafilimu omwe ali ndi magwiridwe antchito ofanana ndi utomoni wa namwali.Nthawi yomweyo, imachepetsa kuchuluka kwa zinyalala za pulasitiki m'chilengedwe ndikuzindikiradi kutsekeka kwapang'onopang'ono pakubwezeretsanso ma phukusi.
•(3).Unilever: Kusintha kukhala rPET pamndandanda wake wazokometsera, kukhala UK'100% yoyamba ya zakudya za PCR
M'mwezi wa Meyi, mtundu wa Unilever's condiment Hellmann adasinthiratu PET (rPET) ya 100% ya ogula ndikuyiyambitsa ku UK.Unilever inanena kuti ngati mndandanda wonsewu utasinthidwa ndi rPET, ungapulumutse matani pafupifupi 1,480 chaka chilichonse.
Pakadali pano, pafupifupi theka (40%) lazinthu za Hellmann zimagwiritsa ntchito pulasitiki yobwezerezedwanso ndikugunda mashelufu mu Meyi.Kampaniyo ikukonzekera kusinthana ndi mapulasitiki obwezerezedwanso pazogulitsa izi kumapeto kwa 2022.
Andre Burger, wachiwiri kwa purezidenti wazakudya ku Unilever UK ndi Ireland, adati:“Hellmann wathu'Mabotolo a condiment ndi mtundu wathu woyamba wa chakudya ku UK kugwiritsa ntchito 100% pulasitiki yobwezerezedwanso ndi ogula, ngakhale pakusinthaku Pakhala zovuta, koma zomwe zatichitikirazi zitithandiza kufulumizitsa kugwiritsa ntchito pulasitiki yobwezerezedwanso ku Unilever.'s ena zakudya zopangidwa.”
PCR yakhala chizindikiro chaECO-ochezeka zipangizo.Mayiko ambiri aku Europe agwiritsa ntchito PCR pakuyika chakudya kuti atsimikizire 100%ECO-waubwenzi.
Ndife opanga okhazikika popanga matumba onyamula khofi kwa zaka zopitilira 20.Takhala m'modzi mwa opanga matumba akuluakulu a khofi ku China.
Timagwiritsa ntchito mavavu abwino kwambiri a WIPF ochokera ku Swiss kuti khofi yanu ikhale yatsopano.
Tapanga zikwama zokomera zachilengedwe, monga matumba opangidwa ndi kompositi ndi zikwama zobwezerezedwanso,ndi zida zaposachedwa za PCR.
Ndiwo njira zabwino kwambiri zosinthira matumba apulasitiki wamba.
Zophatikizira kabukhu lathu, chonde titumizireni mtundu wa thumba, zinthu, kukula ndi kuchuluka komwe mukufuna.Kotero ife tikhoza kukuuzani inu.
