Yintoni kanye kanye izinto zePCR?
1. Ziziphi izinto zePCR?
Izinto zePCR ngokwenene luhlobo "lweplastiki esetyenzisiweyo", igama elipheleleyo yi-Post-Consumer Recycled material, oko kukuthi, imathiriyeli ehlaziyiweyo yasemva komthengi.
Izinto zePCR "zixabiseke kakhulu".Ngesiqhelo, inkunkuma yeplastiki eveliswa emva kokujikeleziswa, ukusetyenziswa kunye nokusetyenziswa kunokuguqulwa ibe yimathiriyeli ekrwada yemveliso yemizi-mveliso ngokuhlaziywa kwakhona ngokwasemzimbeni okanye ukurisayikilishwa kwakhona kweekhemikhali, ukuqonda ukuveliswa ngokutsha kwezixhobo kunye nokuphinda kusetyenziswe.
Ngokomzekelo, izinto ezihlaziyiweyo ezifana ne-PET, i-PE, i-PP, kunye ne-HDPE zivela kwiiplastiki zenkunkuma ezenziwe kwiibhokisi zesidlo sasemini ezisetyenziswa ngokuqhelekileyo, iibhotile ze-shampoo, iibhotile zamanzi amaminerali, imigqomo yomatshini wokuhlamba, njl. Emva kokuphinda kusetyenziswe, zingasetyenziselwa ukwenza entsha izinto zokupakisha..
Ekubeni izinto ze-PCR zivela kwizinto zasemva kwabathengi, ukuba azicutshungulwanga ngokufanelekileyo, ngokuqinisekileyo ziya kuba nefuthe elithe ngqo kwindalo.Ke ngoko, iPCR yenye yeeplastikhi ezisetyenzisiweyo ngoku ezicetyiswayo ziimpawu ezahlukeneyo.
2. Kutheni iiplastiki zePCR zithandwa kangaka?
•(1).Iplastiki yePCR yenye yezalathiso ezibalulekileyo zokunciphisa ungcoliseko lweplastiki kunye negalelo "kwi-carbon neutrality".
Emva kwemigudu engapheliyo yezizukulwana ngezizukulwana zoosokhemesti neenjineli, iiplastiki eziveliswe ngepetroleum, amalahle, negesi yendalo ziye zaba zizinto eziyimfuneko kubomi babantu ngenxa yobunzima bazo, ukuqina nobuhle bazo.Nangona kunjalo, ukusetyenziswa kakhulu kweeplastiki kubangele ukuveliswa kwenkunkuma eninzi yeplastiki.Iplastiki yePost-consumer recycling (PCR) ibe yenye yeendlela ezibalulekileyo zokunciphisa ukungcoliseka kwendalo yeplastiki kunye nokunceda ishishini lemichiza lihambe lisiya “kungathathi hlangothi kwekhabhoni”.
Iipeliti zeplastiki ezisetyenzisiweyo zixutywa nentlaka enyulu ukwenza iindidi zeemveliso zeplastiki ezintsha.Le ndlela ayigcini nje ukunciphisa ukukhutshwa kwe-carbon dioxide, kodwa iyanciphisa ukusetyenziswa kwamandla.
•(2).Sebenzisa iplastiki yePCR ukuqhubela phambili ukukhuthaza ukugaywa kwakhona kweplastiki
Okukhona iinkampani ezisebenzisa iiplastiki zePCR, kokukhona imfuno iya kuba nkulu, nto leyo eya kuthi inyuse ngakumbi ukurisayikilishwa kweeplastiki ezilahlwayo kwaye ngokuthe ngcembe itshintshe imodeli kunye nemisebenzi yoshishino yenkunkuma egayiweyo yokurisayikilishwa kweplastiki, oku kuthetha ukuba inkunkuma encinci yeplastiki iya kugalelwa, itshiswe kwaye igcinwe kwindawo engqongileyo.kwindawo yendalo.
• (3).Ukukhuthazwa komgaqo-nkqubo
Indawo yomgaqo-nkqubo yeeplastiki zePCR iyavuleka.
Thatha iYurophu njengomzekelo, isicwangciso seplastiki se-EU kunye neeplastiki kunye nomthetho werhafu wokupakisha kumazwe afana neBritane neJamani.Ngokomzekelo, i-Revenue yase-UK kunye ne-Customs ikhuphe "Irhafu yePlastiki yokuPakisha".Ireyithi yerhafu yokupakishwa ngeplastiki ehlaziyiweyo engaphantsi kwe-30% ngama-200 eeponti ngetoni nganye.Irhafu kunye nemigaqo-nkqubo ivule indawo yemfuno yeeplastiki zePCR.
3. Zeziphi izigebenga zeshishini ezandisa utyalo-mali lwazo kwiiplastiki zePCR kutshanje?
Okwangoku, uninzi lweemveliso zeplastiki zePCR kwimarike zisasekwe kuhlaziyo lwasemzimbeni.Iya isanda imizi-mveliso yeekhemikhali kumazwe ngamazwe ilandela uphuhliso nokusetyenziswa kweemveliso zeplastiki zePCR ezisetyenzisiweyo.Banethemba lokuqinisekisa ukuba izinto ezisetyenzisiweyo zisebenza ngokufanayo nemathiriyeli ekrwada., kwaye inokufezekisa "ukuncitshiswa kwekhabhoni".
•(1).BASF'I-Ultramid imathiriyeli ehlaziyiweyo ifumana isatifikethi se-UL
I-BASF ibhengeze kule veki ukuba i-Ultramid Ccycled recycled polymer eveliswe kwi-Freeport yayo, eTexas, isityalo sifumene isatifikethi esivela kwi-Underwriters Laboratories (UL).
Ngokutsho kwe-UL 2809, ii-polymers ze-Ultramid Ccycled zihlaziywe ukusuka kwi-post-consumer recycled (PCR) iiplastiki zingasebenzisa inkqubo yokulinganisa ubuninzi ukuhlangabezana nemigangatho yomxholo osetyenzisiweyo.Ibakala lepolymer lineepropati ezifanayo njengezinto eziluhlaza kwaye ayifuni uhlengahlengiso kwiindlela zokucubungula zendabuko.Ingasetyenziswa kwizicelo ezifana nokupakisha iifilimu, iikhaphethi kunye nefenitshala, kwaye yindlela ezinzileyo kwimathiriyeli ekrwada.
I-BASF iphanda ngeenkqubo ezintsha zemichiza ukuze iqhubeke nokuguqula ezinye iiplastiki zenkunkuma zibe yimathiriyeli ekrwada emitsha, enexabiso.Le ndlela inciphisa ukukhutshwa kwegesi ye-greenhouse kunye ne-fossil ekrwada igalelo ngelixa igcina umgangatho wemveliso kunye nokusebenza.
URandall Hulvey, uMlawuli woShishino we-BASF kuMntla waseMelika:
“Ibanga lethu elitsha le-Ultramid Ccycled linika amandla afanayo aphezulu omatshini, ukuqina kunye nokuzinza kwe-thermal njengamabakala emveli, kwaye kuya kunceda abathengi bethu bafezekise iinjongo zabo zozinzo.”
•(2).Mengniu: Faka i-Dow PCR resin
NgoJuni 11, iDow kunye neMengniu ngokudibeneyo babhengeze ukuba baye bathengisa ngempumelelo ifilimu yeresin ecuthekayo emva komthengi.
Kuyaqondwa ukuba esi sisihlandlo sokuqala kwishishini lokutya lasekhaya ukuba iMengniu idibanise amandla ayo endalo yendalo kwaye idityaniswe nababoneleli bezinto zeplastiki, abavelisi bokupakisha, abahlaziyi bezinto ezisetyenzisiweyo kunye namanye amaqela ekhonkco loshishino ukuba baqonde ukuphinda kusetyenziswe kwakhona ukupakishwa kweplastiki, ngokupheleleyo. ukusebenzisa iiplastiki ezisetyenziswe kwakhona zasemva komthengi njengefilimu yokupakishwa kweMveliso.
Umaleko ophakathi wefilimu yesibini yokupakishwa kobushushu obutshatyalaliswayo esetyenziswa ziimveliso zeMengniu uphuma kwifomula yeresin yeDow yePCR.Le fomyula iqulethe i-40% ye-post-consumer materials recycled kwaye inokuzisa umxholo wezinto ezisetyenzisiweyo kwisakhiwo sefilimu ye-shrink iyonke ukuya kwi-13% -24%, eyenza ukuveliswa kweefilimu kunye nokusebenza okufaniswa ne-virgin resin.Kwangaxeshanye, yehlisa isixa senkunkuma yeplastiki kokusingqongileyo kwaye iqonda ngokwenyani usetyenziso oluvaliweyo lokupakishwa ngokutsha.
•(3).Unilever: Ukutshintshela kwi-rPET kuthotho lwayo lwe-condiment, ibe yi-UK's yokuqala 100% PCR ukutya brand
NgoMeyi, i-brand ye-condiment ye-Unilever's Hellmann's yatshintshela kwi-100% ye-PET (rPET) esetyenzisiweyo yasemva komthengi yaza yayisungula e-UK.U-Unilever uthe ukuba lonke olu ngcelele luthatyathelw' indawo yi-rPET, lunokonga malunga neetoni eziyi-1,480 zemathiriyeli ekrwada minyaka le.
Okwangoku, phantse isiqingatha (40%) seemveliso zikaHellmann sele zisebenzisa iplastiki ehlaziyiweyo kunye neeshelufu ngoMeyi.Inkampani iceba ukutshintshela kwiplastiki enokuphinda isetyenziswe kolu luhlu lweemveliso ekupheleni kuka-2022.
U-Andre Burger, usekela mongameli wokutya e-Unilever UK nase-Ireland, uthe:“UHellmann wethu'Iibhotile ze-condiment ziyi-brand yethu yokuqala yokutya e-UK ukusebenzisa i-100% ye-post-consumer yeplastiki ehlaziyiweyo, nangona kolu tshintsho Kubekho imingeni, kodwa amava aya kusenza sikwazi ukukhawulezisa ukusetyenziswa kweplastiki ehlaziyiweyo kwi-Unilever.'s ezinye iintlobo zokutya.”
I-PCR ibe ileyibhile yeI-ECO-izixhobo ezinobubele.Amazwe amaninzi aseYurophu afake isicelo se-PCR kwipakethe yokutya ukuqinisekisa i-100%I-ECO-nobubele.
Singumvelisi okhethekileyo ekuveliseni iingxowa zokupakisha zekofu ngaphezu kweminyaka engama-20.Siye saba ngomnye wabenzi bebhegi yekofu enkulu eTshayina.
Sisebenzisa iivalvu ze-WIPF ezisemgangathweni ezisuka eSwitzerland ukugcina ikofu yakho intsha.
Siphuhlise iibhegi ezilungele ukuphilisana kwendalo, ezifana neengxowa ezivundisiweyo kunye neengxowa ezinokuphinda zisetyenziswe,kunye nezixhobo zePCR zamva nje.
Zizona zikhetho ezingcono zokutshintsha iingxowa zeplastiki eziqhelekileyo.
Iqhotyoshelwe kwikhathalogu yethu, nceda usithumelele uhlobo lwebhegi, izinto eziphathekayo, ubungakanani kunye nobuninzi obufunayo.Ngoko sinokukucaphula.
