Ukuvuselela "okuluhlaza" kusuka emabhodleleni epulasitiki
I-PET (i-PolyEthylene Terephthalate) ingenye yepulasitiki esetshenziswa kakhulu. Ine-ductility enhle, ukukhanya okuphezulu, nokuphepha okuhle. Kuvame ukusetshenziselwa ukwenza amabhodlela esiphuzo noma ezinye izinto zokupakisha ukudla. . Ezweni lami, i-rPET (i-PET egaywe kabusha, ipulasitiki ye-PET egaywe kabusha) eyenziwe ngamabhodlela esiphuzo esenziwe kabusha ingasetshenziswa kabusha ezimotweni, kumakhemikhali ansuku zonke nakweminye imikhakha, kodwa okwamanje ayivunyelwe ukuthi isetshenziswe ekufakweni kokudla. Ngo-2019, isisindo samabhodlela e-PET esiphuzo adliwe ezweni lami safinyelela kumathani ayizigidi ezi-4.42. Nokho, i-PET ithatha okungenani amakhulu eminyaka ukubola ngokuphelele ngaphansi kwezimo zemvelo, okuletha umthwalo omkhulu emvelweni nakwezomnotho.
Ngokombono wezomnotho, ukulahla ukupakishwa kwepulasitiki ngemva kokusetshenziswa kwesikhathi esisodwa kuzolahlekelwa i-95% yenani lokusebenzisa; ngokombono wemvelo, kuzoholela nasekuncishisweni kwesivuno sezitshalo, ukungcoliswa kolwandle nezinye izinkinga eziningi. Uma amabhodlela epulasitiki e-PET esetshenzisiwe, ikakhulukazi amabhodlela eziphuzo, egaywa kabusha ukuze agaywe kabusha, kuzoba nokubaluleka okukhulu ekuvikelweni kwemvelo, umnotho, umphakathi nezinye izici.
Idatha ibonisa ukuthi izinga lokugaywa kabusha kwamabhodlela esiphuzo se-PET ezweni lami lifinyelela ku-94%, lapho ngaphezu kuka-80% we-rPET engena embonini yefayibha egaywe kabusha futhi isetshenziselwa ukwenza izidingo zansuku zonke njengezikhwama, izingubo zokugqoka, nama-parasols. Eqinisweni, ukwenza kabusha amabhodlela esiphuzo se-PET abe yi-rPET yebanga lokudla akukwazi nje ukunciphisa ukusetshenziswa kwe-PET emsulwa futhi kunciphise ukusetshenziswa kwezinsiza ezingavuseleleki njenge-petroleum, kodwa futhi kwandise inani lemijikelezo ye-rPET ngokusebenzisa amasu okucubungula esayensi naqinile, ukwenza ukuphepha kwayo Sekuvele kufakazelwe kwamanye amazwe.
Ngaphezu kokungena ohlelweni lokugaywa kabusha, amabhodlela ezwe lami emfucuza yesiphuzo se-PET ageleza ngokuyinhloko ezindaweni zokuhlanza imfucumfucu yokudla, izindawo zokulahla imfucumfucu, izikhungo zokushiswa kwemfucuza, amabhishi nezinye izindawo. Nokho, ukugcwaliswa komhlaba kanye nokushiswa kungaholela ekungcoleni komoya, inhlabathi namanzi angaphansi komhlaba. Uma udoti wehliswa noma imfucuza eyengeziwe igaywa kabusha, imithwalo yemvelo nezindleko zingancishiswa.
I-PET evuselelwe inganciphisa ukukhishwa kwe-carbon dioxide ngo-59% kanye nokusetshenziswa kwamandla ngo-76% uma kuqhathaniswa ne-PET eyenziwe nge-petroleum.
Ngo-2020, izwe lami lenza ukuzibophezela okuphezulu ekuvikelweni kwemvelo kanye nokunciphisa intuthu engcolisayo: ukufeza umgomo wokukhuphuka kwekhabhoni ngaphambi kuka-2030 kanye nokungathathi hlangothi ngaphambi kuka-2060. ukuguqulwa kwentuthuko yezomnotho nezenhlalakahle. Njengenye yezindlela ezisebenzayo zokugaywa kabusha kwamapulasitiki alahlwayo, i-rPET ingadlala indima ekukhuthazeni ukuhlola nokuthuthukiswa kohlelo lokulawulwa kwemfucuza, futhi ibaluleke kakhulu ekukhuthazeni ukufezwa komgomo “wekhabhoni ephindwe kabili”.
Ukuphepha kwe-rPET ekufakweni kokudla kubalulekile
Njengamanje, ngenxa yezindawo ze-rPET ezinobungani bemvelo, amazwe amaningi nezifunda emhlabeni wonke ziye zavumela ukusetshenziswa kwayo emaphaketheni okudla, futhi i-Afrika nayo isheshisa ukwanda kokukhiqizwa kwayo. Kodwa-ke, ezweni lami, ipulasitiki ye-rPET ayikwazi okwamanje ukusetshenziswa emaphaketheni okudla.
Akukho ukushoda kwezimboni ze-rPET ezisezingeni lokudla ezweni lethu. Eqinisweni, izwe lethu liyindawo enkulu kunazo zonke emhlabeni yokugaywa kabusha nokucubungula ipulasitiki. Ngo-2021, umthamo wokuvuselela ibhodlela lesiphuzo se-PET wezwe lami uzosondela kumathani ayizigidi ezi-4. Ipulasitiki ye-rPET isetshenziswa kakhulu kuzimonyo ezisezingeni eliphezulu, ukupakishwa komkhiqizo wokunakekelwa komuntu siqu, izimoto nezinye izinkambu, kanti i-rPET yebanga lokudla Ithunyelwa kwamanye amazwe.
"Umbiko" ubonisa ukuthi abathengi abangu-73.39% bathatha isinyathelo sokuphinda basebenzise kabusha noma baphinde basebenzise amabhodlela esiphuzo alahliwe ekuphileni kwabo kwansuku zonke, futhi u-62.84% wabathengi uveza izinhloso ezinhle zokugaywa kabusha kwe-PET ukuze kusetshenziswe ekudleni. Abathengi abangaphezu kuka-90% bazwakalise ukukhathazeka ngokuphepha kwe-rPET esetshenziswa ezintweni zokupakisha ukudla. Kungabonakala ukuthi abathengi baseShayina ngokuvamile banesimo sengqondo esihle mayelana nokusetshenziswa kwe-rPET emaphaketheni okudla, nokuqinisekisa ukuphepha kuyisidingo esidingekayo.
Ukusetshenziswa kweqiniso kwe-rPET emkhakheni wokudla kufanele kusekelwe ekuhlolweni kokuphepha kanye nokugadwa kwangaphambili nangemuva komcimbi ngakolunye uhlangothi. Ngakolunye uhlangothi, kulindeleke ukuthi umphakathi wonke usebenzisane ukukhuthaza ngokuhlanganyela ukusetshenziswa kwenani eliphezulu kwe-rPET futhi kuthuthukiswe ukuthuthukiswa komnotho oyindilinga.
