Ikusasa lezikhwama zepulasitiki ezivundile emkhakheni wezokundiza

Iqhutshwa ukuncishiswa kwegagasi lomhlaba wonke lokuncishiswa kwepulasitiki, imboni yezindiza isheshisa ukuguqukela kokusimama, lapho ukusetshenziswai-compostable izikhwama zepulasitiki ziba impumelelo ebalulekile. Kusukela enkampanini ye-us air cargo kuya ezinhlanganweni zezindiza ezintathu ezinkulu zaseShayina, umhlaba wezindiza zamazwe ngamazwe usungula kabusha imvelo yezinto ezitholakala emkhunjini futhi unikeze umfutho omusha endizeni enobungani bemvelo ngokusebenzisa izinto ezintsha kanye nobuchwepheshe.

I-Compostableizinqubo embonini yezokundiza yamazwe ngamazwe

1.Isinyathelo sokunciphisa ipulasitiki sempahla yezindiza zaseMelika

Izimpahla zezindiza zaseMelika, ngokubambisana neI-Bionnatur Plastics, izipeshelii-compostable Amapulastiki angezwe ezithakweni eziphilayo ukuze athathele indawo amafilimu endabuko ama-pallet coatings kanye nokupakishwa okunwetshiwe. Ngo-2023, lesi sinyathelo sanciphisa imfucuza yepulasitiki ngamakhilogremu angaphezu kuka-150,000, okulingana namabhodlela amanzi ayizigidi ezingu-8.6 1. Le nto iyancipha kuphela eminyakeni engu-8 kuya kwengu-12 ngaphansi kwezimo zokulahla imfucumfucu, ngokushesha kakhulu kuneminyaka eyi-1000 yepulasitiki evamile.

2.Amazinga e-China Airline Association aqhuba uguquko lwemboni

Inhlangano yezokuthutha zasemoyeni yase-China ikhiphe imininingwane yokushintshwa kwemikhiqizo yepulasitiki elahlwayo, engaboli, yezindiza zabagibeli basekhaya, isho ukuthi i-polylactic acid (PLA) ne-polycaprolactone (PCL) yizinto ezibolekayo. I-ESUN esheng nezinye izinkampani zenze izinkomishi zephepha, izinkomishi kanye nemikhiqizo engalukiwe ehlangabezana nezidingo zezindiza futhi esetshenziswa kabanzi ekuhlinzekeni ama-cabin service.

3.Isinyathelo esibanzi sokunciphisa ipulasitiki sezindiza zaseShayina

Air China: imimese, izimfoloko, izinkomishi, njll. zezindiza zasekhaya konke kushintshiwe ngakhoi-compostable izinto kanye nokuhlolwa kwenziwe ngayoi-compostable amashidi epulasitiki.3

I-Easa: Izinto zokuhlinzekwa kwe-28 zenziwe nge-100%i-compostable izinto zokwakha, izembozo zama-earphone nezikhwama zokupakisha zibuyekezwa ngezinto ezingama-37 ezihambisana nemvelo.

I-Air south: misa izindiza zamazwe ngamazwe kusukela ngo-2023 utshani bepulasitiki obungaboli, induku yokuxuba, kanye nokucwaninga nokuthuthukiswa kwenkomishi yephepha ye-PLA eco-friendly, ukukhiqizwa konyaka kufinyelela ezigidini ezingu-20 7.

Impumelelo yomhlaba wonke ezintweni ezintsha

Ubuchwepheshe bokucekela phansi kuyo yonke inkundla yemvelo: izinto ezithuthukiswe yi-cohaina kazwelonke zingonakala enhlabathini, emanzini ahlanzekile namanzi olwandle, ngenani lokuwohloka elingaphezu kwama-90% ezinsukwini ezingama-560 emanzini olwandle, futhi zifanele ukupakishwa kwezindiza kanye nesimo sasolwandle 8.

Isicelo esiyinhlanganisela ye-PLA ne-PCL: i-esun PLA inkomishi yephepha elula nefilimu yokuxuba ye-PCL inokubili ukumelana nokushisa kanye nokonakala ukuze kuhlangatshezwane nezidingo zokupakishwa kokudla kwe-aeronautical 2.

Imikhiqizo yokugcina esekwe ku-bio: izikhwama ze-henan longdu tianren ezizingelayo ezisekelwe ku-bio kanye nezikhwama zikadoti zingene emkhakheni wezindiza futhi zibole ngokuphelele zibe isikhutha namanzi ezinyangeni ezi-3-6.

Amathrendi nezinselele zesikhathi esizayo

Nakubai-compostable amapulasitiki anesithembiso esikhulu embonini ye-aerospace, abhekana nezinselele ezifana nezindleko, ukuzinza kwe-supply chain kanye nokuvumelana kwamazinga omhlaba. Ngokuthuthukiswa “komkhawulo wepulasitiki” we-EU futhi kuthuthukiswe inhloso yaseChina “yekhabhoni ephindwe kabili”, imboni yezokundiza noma izofeza ukusabalala okuphelelei-compostable ukupakishwa eminyakeni emihlanu ezayo.

Isiphetho sesiphetho

Ukusuka eNyakatho Melika kuya e-Asia, imboni yezindiza iyasetshenziswai-compostable amapulasitiki njenge-pivot yokuthuthukisa ikusasa lokundiza okuluhlaza. Lolu shintsho alulona nje uphawu lokuzibophezela kwezemvelo, kodwa futhi luyisidingo sokuthuthukiswa okuqhubekayo komkhakha. "Ukungcola okumhlophe" phezu kwesibhakabhaka esiluhlaza kuyoba yinto yesikhathi esidlule, njengoba ubuchwepheshe nezinqubomgomo zikhula.
