Inqubomgomo yezemvelo nemihlahlandlela yokuqamba
Eminyakeni yamuva nje, ukuguquka kwesimo sezulu kanye nezinhlobo ezahlukahlukene zokungcola kubikwe ngokuqhubekayo, ukuheha amazwe amaningi kanye namazwe amabhizinisi ahlongoze izinqubomgomo zokuvikela ezemvelo ngokulandelana.
I-United Nations Everovil Assembly (U-UNA-5) ivume ukulungiswa komlando ngomhlaka 2 Mashi 2022 ukuqeda ukungcoliswa kwepulasitiki ngonyaka ka-2024. Engxenyeni ye-COCA-Cola's 2025's Recycluble iyi-100% esebenza kabusha noma isebenza kabusha.
Ngaphezu kwalokho, izinhlangano zomhlaba wonke, ezifana nokupakisha okuguquguqukayo komnotho we-ceflex kanye ne-theory yempahla yabathengi Lezi zimiso zokuklama ezimbili zinemikhombandlela efanayo ekuvikelweni okufanayo kokufakwa okuguqukayo: 1) Izinto ezizodwa kanye ne-all-polyolefivifisi isesigabeni sezinto ezisetshenziswayo; 2) Akekho isilwane, i-nylon, i-PVC nezinto ezingokonakalayo zivunyelwe; 3) I-Barrier ungqimba yokuhlanganisa i-tier ayikwazi ukwedlula i-5% yayo yonke.
Ubuchwepheshe busekela kanjani ukufakwa okuguquguqukayo kwemvelo
Ngenxa yezinqubomgomo zokuvikela imvelo ezikhishwe ekhaya nakwamanye amazwe, kanjani ukusekela ukuvikelwa kwemvelo kokufakwa okuguqukayo?
Okokuqala, ngaphezu kwezinto ezingokonakalayo zokwehlukana nobuchwepheshe, abakhiqizi bakwamanye amazwe batshalile imali ekuthuthukisweni kweUkuvuselelwa kabusha kwepulasitiki kanye namapulasitiki asuselwa kwi-bio kanye nemikhiqizo. Isibonelo, i-Eastman yase-United States etshalwe kubuchwepheshe be-polyester recycling, i-toray of Japan imemezele ukuthuthukiswa kwe-bio-based nylon N510, kanye neqembu le-suntory laseJapan limemezele ngempumelelo i-prototype yebhodlela le-bio elisuselwa ku-100%.
Okwesibili, ukuphendula inqubomgomo yasekhaya yokuvimba amapulasitiki asetshenziswa ngakunye, ngaphezu kwePla ezibonakalayo ezibonakalayo, IChina iphinde yatshalileEkuthuthukisweni kwezinto ezahlukahlukene ezingokonakalayo ezifana ne-Pbat, PBS nezinye izinto nezicelo zazo ezihlobene. Ingabe izakhiwo ezibonakalayo zezinto zokwakha ezingonakalayo zihlangabezana nezidingo ezisebenza ngokusebenza eziningi zokupakishwa okuguqukayo?
Kusuka ekuqhathanilo kwezindawo ezibonakalayo phakathi kwamafilimu aphezulu we-petrochemical namafilimu anenkani,Izakhiwo zesithiyo sezinto ezingonakalayo zisekude kakhulu namafilimu endabuko. Ngaphezu kwalokho, yize izinto ezahlukahlukene zokubopha zingahle ziphinde zihlanganiswe ngezinto ezingokonakalayo, izindleko zezinto zokwakha kanye nezinqubo zizoqina, kanye nokusetshenziswa kwezinto ezingokonakalayo emaphaketheni athambile, okuyizikhathi ezingama-2-3 izindleko zefilimu yasekuqaleni ye-petrochemical, kube nzima ngokwengeziwe.Ngakho-ke, ukusetshenziswa kwezinto ezingonakalayo zokupakisha eziguquguqukayo nakho kudinga ukutshala imali ocwaningweni nasekuthuthukisweni kwezinto ezingavuthiwe ukuxazulula izinkinga zezakhiwo nezindleko.
Ukupakisha okuguquguqukayo kunenhlanganisela eyinkimbinkimbi yezinto ezahlukahlukene zokuhlangabezana nezidingo zomkhiqizo zokubukeka okuphelele nokusebenza kwephakheji. Ukuhlukaniswa okulula kwezinhlobo ezahlukahlukene zamafilimu kufaka phakathi ukuphrinta, imisebenzi yesici nokushisa ukushisa, izinto ezisetshenziswayo zingu-OPP, PEVC, ony, i-alumining failing filts, i-PVC kanye ne-Petg ukushisa ukushisa okunciphayo kanye ne-mdope ethandwayo ethandwa yi-bate.
Kodwa-ke, ngokombono womnotho oyindilinga wokuphinda usebenzise kabusha futhi usebenzise imigomo ye-CGF ye-CGF yezomnotho oyindilinga wokupakisha okuguqukayo kubukeka sengathi ingenye yezinkomba zohlelo lokuvikela okuguqukayo.
Okokuqala, izinto eziningi zokupakisha eziguquguqukayo ziyi-PP eyodwa impahla, efana ne-noodle Packiging BOPP / MCPP, le nhlanganisela yezinto ingahlangabezana nento eyodwa yomnotho oyindilinga.
Okwesibili,Ngaphansi kwezimo zezinzuzo zezomnotho, uhlelo lokuvikela imvelo lokufakwa okuguqukayo lungenziwa ngendlela eyakhiwe ngesakhiwo sokupakisha (i-PP & PE) ngaphandle kwezilwane ezifuywayo. Lapho izinto zokufunda ezenzelwe i-bio noma izinto ezinesithiyo semvelo zivame kakhulu, izinto ze-petrochemical kanye nama-aluminium floils zizothathelwa indawo kancane ukuze zifinyelele esakhiweni sephakheji esithambile semvelo.
Ekugcineni, ngokombono wezindlela zokuvikela imvelo kanye nezimo ezibonakalayo, izixazululo ezibonakalayo ezinokwenzeka kakhulu zokufaka izisombululo eziguqukayo zemvelo ukuklama izisombululo ezihlukile zokuvikela imvelo kumakhasimende ahlukene kanye nezindlela ezihlukile, ezifana neplastiki eyodwa, ephepheni, ezingasetshenziswa kwizimo ezahlukahlukene zokusebenzisa. Ngakho-ke, kuphakanyiswa ukuthi esibonelweni sokuhlangabezana nezidingo zokupakishwa komkhiqizo, okuqukethwe kanye nokwakheka kufanele kuguqulwe kancane kancane ohlelweni lwamanje lokuvikela imvelo olungabizi kakhulu. Lapho uhlelo lokuphinda usebenzise kabusha luphelele, ukuvumelanisa kabusha nokusetshenziswa kabusha kokufakwa okuguqukayo kuyindaba.
