Angenziwa kanjani kabusha amaphakheji epulasitiki?Yiziphi izitayela zobuchwepheshe ezifanele ukunakwa?
Kuleli hlobo, ukupakishwa kwepulasitiki kuthinta izindaba njalo!Okokuqala, amabhodlela aluhlaza aluhlaza ase-UK ayisikhombisa ashintshiwe afakwa emaphaketheni asobala, kwase kuthi uMengniu no-Dow babona ukwenziwa kwemboni yefilimu encipha ukushisa equkethe izinto ze-PCR.Lona umzamo wokuqala ka-Mengniu wokusebenzisa i-PCR emaphaketheni esibili.
Kukhona futhi nomkhiqizi we-ayisikhilimu wamazwe ngamazwe i-foneri (ibhizinisi elihlanganyelwe phakathi kuka-Finch no-RR) o-ode izinkomishi zika-ayisikhilimu ze-polypropylene ezivuselelekayo eziyi-100 Z.U-ayisikhilimu opakishwe ku-polypropylene egaywe kabusha uzothengiswa e-Italy.
Umqondo oyisisekelo wokuqanjwa kabusha kobuchwepheshe bokupakisha epulasitiki kulezi zigaba ezahlukene uyafana: ukuphinda kusetshenziswe kabusha akusesona isiqubulo, kodwa isishoshovu "esigxilile".Ukupakisha okugaywa kabusha kudlala indima ebaluleke kakhulu.
Ngokusho kwe-repot kanye ne-dat, imakethe yokupakishwa kwepulasitiki esimeme yomhlaba wonke kulindeleke ukuthi ifinyelele ku- $ 127.5 billion ngo-2028, ngenani lokukhula elihlanganisiwe lonyaka lika-6%, lapho ukupakishwa okuphinda kusetshenziswe kabusha kubalelwa engxenyeni enkulu kakhulu.
Angenziwa kanjani kabusha amaphakheji epulasitiki?Yiziphi izitayela zobuchwepheshe ezifanele ukunakwa?
01 impahla eyodwa ithuthukisa kakhulu inani elithambile lokugaywa kabusha kwamaphakheji
Eminyakeni yakamuva, isisombululo esisodwa sokupakisha esinevelu elihle lokugaywa kabusha siye sadalulwa, futhi sizuze ukushintshwa kwezinto ezihlukene eziyinhlanganisela kwezinye izinhlelo zokusebenza.Uma kuqhathaniswa nezinto eziyinhlanganisela yezendlalelo eziningi, ukupakishwa kwepulasitiki okukodwa akudingi ukukhunyulwa ngemva kokusetshenziswa, futhi nenani elingaphinda lisetshenziswe lithuthukiswa kakhulu.Noma ngabe kusekufakweni okuqinile noma okuthambile, okokusebenza okukodwa kuhlonishwa kakhulu.
Isibonelo: ikhanda lepompo le-PE eligcwele demetallized
Ekupakishweni okuqinile kwamakhemikhali kwansuku zonke, ikhanda lepompo lendabuko lingaqukatha izinto ezihlukene, futhi kwezinye izimo, lingase lukhuni ngisho nenqubo yokugaywa kabusha.Lolu hlobo lwekhanda lephampu elinepulasitiki nesakhiwo esixubile sensimbi kwandisa ukunemba kokupakishwa kamuva nokuvuselela kabusha.
Okunye isibonelo: konke ukupakishwa okuguquguqukayo kokudla kwe-PE kumelana ne-oxygen futhi kunobufakazi bomswakama
Emkhakheni wokupakisha okuthambile kokudla, ukupakishwa kwempahla eyodwa kuye kwangena kancane kancane ekudleni kwezingane kanye nemikhiqizo yobisi.Isibonelo, inkampani ye-Garbo inikeza isikhwama esisodwa sokupakisha ukudla kwengane se-organic bananamango puree.Ngokuqhathanisa, ukupakishwa kwefilimu ngento eyodwa kulula ukugaywa kabusha.
02 ibhodlela le-PET elikhanyayo eliqhekeka umbala wokugaya kabusha kunzima
Ekugayweni kabusha kwamabhodlela e-PET, amabhodlela e-PET anombala azokhuphula ubunzima bokuphinda agaywe kabusha futhi anciphise inani lokugaywa kabusha, kuyilapho amabhodlela e-PET abonakala elungele ukugaywa kabusha.Ngaphezu kwalokho, amabhodlela e-PET asobala nawo alula ukuthuthukisa ukukhanga kwamashalofu wempahla.
Ngakho-ke, amabhodlela e-transparent et aye athandwa kakhulu eminyakeni emibili edlule.I-Coca Cola ishintshe ibhodlela layo leqhwa leminyaka engu-50 lisuka eluhlaza laya ekubeni sobala eminyakeni emibili edlule, kanti abayisikhombisa e-UK nabo bazoqala kuleli hlobo ukushintsha iphakheji ye-FET engu-375m, 500m kanye ne-600ml isuka kumbala onqenqemeni wasekuqaleni iye obala ukuze igaywe kabusha.Ngaphezu kwe-Coke Sprite kanye nokupakishwa okusobala okuyisikhombisa, umkhiqizi wobisi we-agenlian i-mastelene HNOS naye uzoqala ukusebenzisa ibhodlela le-PET elikhanyayo elakhiwe yi-Amcor ukugcwalisa ubisi lwayo olusha.
03 sebenzisa kabusha i-PCR futhi uguqule imfucuza ibe ingcebo
Igama eligcwele le-PCR lithi post consumerreydedmateral, okusho ukuthi i-post consumer resin egaywe kabusha ngesi-Chinese, noma i-PCR ngamafuphi.Ivamise ukwenziwa ngezinhlayiya ezintsha zepulasitiki ngemva kokuvuselela kabusha amapulasitiki alahlwayo nokuhlunga, ukuhlanza kanye nezinhlayiya zomgwaqo ngohlelo lokugaywa kabusha.Le zinhlayiya zepulasitiki zinesakhiwo esifanayo nesepulasitiki ngaphambi kokugaywa kabusha.Lapho izinhlayiya ezintsha zepulasitiki zixutshwa ne-resin yasekuqaleni, kungadalwa imikhiqizo emisha ehlukahlukene yepulasitiki.Le ndlela ayigcini nje ukunciphisa ukukhishwa kwe-carbon dioxide, kodwa futhi inciphisa ukusetshenziswa kwamandla.I-PCR ingaphinda igaywe ngezinto ezifuywayo, i-PE, i-PP, i-HDPE, njll.
Imithetho ye-EU ikhuthaza amabhizinisi ukuthi athuthukise ukusetshenziswa kwe-PCR
I-European Union's disposable plastics Directive idinga ukuthi ingxenye yezingxenye zepulasitiki ezigaywe kabusha emabhodleleni e-PE yesibili kufanele ikhuphuke ibe ngu-25% kusukela ngo-2025. Kusukela ngo-2030, ingxenye yezingxenye zepulasitiki ezigaywe kabusha kuwo wonke amabhodlela eziphuzo zepulasitiki kufanele zifinyelele ku-30%, izinto ze-PCR i-akhawunti yokupakisha i-30%, kanti izinto ze-PCR kanye nengxenye okuhloswe ngayo kwe-Eurasia Group ingama-40%.
Ukwandisa ingxenye yezinto ze-PCR ekupakishweni sekube ngelinye lamasu abalulekile ezinkampanini ze-FMCG ukuze zifinyelele kumbono 2025 noma umbono 2030. I-Unilever ihlela ukuzuza u-25% wezinto ze-PCR ekupakishweni ngo-2025, kanti iqembu le-Mars lihlela ukuzuza ukupakishwa ngo-2025. NgoJuni kulo nyaka, i-Coca Cola yaqhubeka nokwandisa isakhiwo sayo esimeme eYurophu futhi yakhuthaza ukukhiqizwa nokusebenzisa amabhodlela e-PET e-Italy naseJalimane.Phambilini, imemezele ukukhiqiza kancane kancane amabhodlela ezilwane eziyi-100% eNetherlands, Norway, Sweden nakwezinye izindawo.
Umthombo: Inethiwekhi yokugcina impahla yepulasitiki
