Umkhiqizi ochwepheshe wemishini yokushisa ukushisa.
NgoMashi 2022, Ingqungquthela Yesihlanu Yezemvelo Ye-UN yaqhubeka nokudlulisa “Isinqumo Sokungcoliswa Kwepulasitiki (Okusalungiswa)” eNairobi, inhloko-dolobha yaseKenya. Emhlanganweni, inhloko yezwe, ungqongqoshe wezemvelo kanye nabanye abameleli abavela emazweni angu-175 basayine lo mlando. Lesi sinqumo sihlose ukukhuthaza ukubuswa komhlaba wonke kokunciphisa ukungcoliswa kwepulasitiki futhi sinethemba lokuqeda ukungcoliswa kwepulasitiki ngo-2024.
Ukunakwa kwezinto eziwohlokayo
Ngokombiko wangaphambilini wezemvelo okhishwe yi-OECD (Inhlangano Yezokubambisana Nezokuthuthukiswa Komnotho), ngo-2019, umkhiqizo wonyaka wemikhiqizo yepulasitiki yomhlaba wonke ungamathani ayizigidi ezingama-460, kanti udoti wepulasitiki wonyaka usufinyelele amathani ayizigidi ezingama-353. Imikhiqizo yokukhiqiza, okuhlanganisa ukupakishwa kwepulasitiki (40 %), izimpahla zabathengi bepulasitiki (12), izindwangu (11%), njll.
Ngokuthuthukiswa kwezinqubomgomo, izinto ezibolayo eziphilayo zizoqhubeka nokwanda.
Ukuncintisana kwamandla okukhiqiza
Njengamanje, ipulasitiki ewohlokayo emakethe ingahlukaniswa ngezinhlobo ezimbili: "isisekelo se-petroleum" kanye "nesisekelo sezinto eziphilayo". Umehluko phakathi kwalokhu kokubili uhlukaniswe ikakhulukazi ekukhiqizeni izinto zokusetshenziswa. Ipulasitiki ewohlokayo esekwe kuphethiloli ikhiqizwa ngokusekelwe kumandla ensalela, ikakhulukazi i-PBS (polynoxylxylxylxyl glycol), i-PBAT (i-alcoholic glycolic glycolin ne-phenyl -dysteenol (i-polymer evamile), i-PCL (i-polycopide), njll. kummbila, utshani nezinye izinto eziphilayo, ikakhulukazi i-PLA (i-polylactic acid) ne-PHA (i-polyxide alkyl).
Phakathi kwezinto ezishiwo ngenhla ezibolayo, uma kuqhathaniswa nezinye izinto eziphilayo eziwohlokayo, amanani e-PLA (i-polyal acid) kanye ne-PBAT aphansi uma kuqhathaniswa, futhi inqubo yokukhiqiza isivuthiwe. Okuhlukile okuyinhloko kwepulasitiki yendabuko.
Izinto zokusetshenziswa ze-PLA ikakhulukazi ummbila notshani. Ngemuva kokusetshenziswa, ingabola ngokushesha ibe yi-carbon dioxide, amanzi kanye nosawoti we-inorganic ngaphansi kwezimo ze-compost (umquba wezimboni). (PLA) ukukhiqizwa kwakha umjikelezo wekhabhoni.
Kufanele siqwashise ngokuvikelwa kwemvelo futhi sinciphise ukungcoliswa kwepulasitiki. Eyethuumshini we-wholesale thermoforming ingakhiqiza i-tableware yesikhathi esisodwa ye-PLA, ukusebenza okulula nokulula, uhlelo oluhlakaniphile, olungahlangabezana nezidingo zakho zokukhiqiza.
