Isikhwama seplastiki sepulasitiki esikhokhwayo esenziwe nge-pla ne-pbat

Incazelo emfushane:

Izinto ezisezingeni eliphezulu zekhwalithi, iwindi elicacile, ukukhiya kwe-zip

Izikhwama zepulasitiki ze-biodegramable

Ukubeka nje, okuthile kuyinto eyingqayizivele lapho izinto eziphilayo, njengesikhunta noma amagciwane, zingakudiliza. Izikhwama ze-biodegradable zenziwa ngezinto ezisetshenziselwa izitshalo ezinjenge-corn ne-kakotch starch kunokuba kune-petroleum. Kodwa-ke uma kukhulunywa ngalolu hlobo lwepulasitiki, kunezimo ezithile ezidingekayo ukuze isikhwama siqale kwi-biodergade.

Okokuqala, amazinga okushisa adinga ukufinyelela ama-degree angama-50 Celsius. Okwesibili, isikhwama sidinga ukuvezwa ukukhanya kwe-UV. Emvelweni wasolwandle, ubuzoba nzima ukuhlangabezana nalezi zindlela. Futhi, uma izikhwama ze-bioderbradable zithunyelwa ekugcwalisweni komhlaba, zibhidliza ngaphandle komoya-mpilo ukukhiqiza i-methane, igesi ebamba ukushisa ngethamo lokufudumeza amahlandla angama-21 anamandla amakhulu kune-carbon dioxide.

Izikhwama zepulasitiki ezingcolile noma ezingonakalisiwe

Izinto ezingokonakala azinazo izidalwa eziphilayo njengengxenye ebalulekile yenqubo yokuqhekeka. Izikhwama ezingokonakalayo azikwazi ukuhlukaniswa njenge-biodegradable noma zikhuthele. Esikhundleni salokho, izengezo zamakhemikhali ezisetshenziswe epulasitiki zivumela isikhwama ukuze sibhidlize ngokushesha kunesikhwama sepulasitiki esijwayelekile.

Empeleni izikhwama zikhishwe 'njengezinkohliso' ngokuqinisekile azizuzisi, futhi zingaba zimbi kakhulu emvelweni! Izikhwama ezingokonakalisiwe ezihlukanisiwe ziba izingcezu ezi-microplastic ezisheshayo ze-microplastic, futhi namanje zibeka izinsongo ezinkulu empilweni yasolwandle. Ama-Microplastics afaka iketanga lokudla eliphansi phansi, adliwe ngezinhlobo ezincane bese uqhubeka nokwenza iketanga lokudla njengoba lezi zinhlobo ezincane zidliwa.

UProfesa Tony Underwood ovela e-University of Sydney uchaze izikhwama zepulasitiki ezingokoqobo ngokuthi "hhayi isisombululo kunoma yini, ngaphandle kokuthi sijabule kakhulu ukuwususela amapulasitiki asayizi wezinhlayiyana kunokuba upulasitiki osayizi wepulasitiki kunokuba abe ngopulasitiki osayizi weplastiki."

"Hhayi ikhambi lanoma yini, ngaphandle kokuthi sijabule kakhulu ukuwususela konke kumapulasitiki asayizi wezinhlayiyana kunokuba upulasitiki osayizi wepulasitiki."

Izikhwama zepulasitiki ezikhokhiwe

Igama elithi 'compostable' lidukisa kakhulu umthengi omaphakathi. Ungacabanga ukuthi isikhwama selebuli 'esikhohlisayo' singasho ukuthi ungayiphonsa kumquba wakho wangemuva eceleni kwezithelo zakho zezithelo nezithelo zakho ze-Vegie, ngakwesokudla? Akulungile. Izikhwama ze-biodegrade ezikhokhwayo, kepha ngaphansi kwemibandela ethile.

Izikhwama ezikhohlisayo zidinga ukuhlanganiswa esikhungweni esithile somquba, okumbalwa kakhulu e-Australia. Izikhwama ezikhohlakele zivame ukwenziwa ngezinto zezitshalo ezibuya ezingxenyeni eziphilayo lapho zicutshungulwa yilezi zindawo, kepha inkinga iseqinisweni kunezikhungo ezingama-150 kuphela zalezi zikhungo zase-Australia.

Ngingakwazi ukuphinda usebenzise izikhwama zepulasitiki?

Izikhwama zepulasitiki, izikhwama ze-biodegradable, ezingokonakalayo nezingafanele azikwazi ukufakwa emgqonyeni wakho ojwayelekile wokuvuselela kabusha ekhaya. Bangaphazamisa kakhulu inqubo yokuphinda basebenzise kabusha uma bekhona.

Kodwa-ke, iSupermarket Yakho Yendawo inganikela nge-Plassical Bag Recycling. Ezinye izitolo ezinkulu zingaphinde zivuselele kabusha 'izikhwama eziluhlaza' ezidwenguliwe noma ezingasasebenzi. Thola indawo yakho eseduze lapha.

Yisiphi isikhwama esihle kunazo zonke okufanele usisebenzise?

Isikhwama se-BYO siyindlela engcono kakhulu. Ukulebula ezikhwameni zepulasitiki kungadida futhi kudukise, ngakho-ke ukuletha isikhwama sakho siqu kuzogwema ukulahla isikhwama sepulasitiki ngokungalungile.

Tshala imali esikhwameni esiqinile se-canvas, noma isikhwama esincane sekotini ongasiphonsa esikhwameni sakho bese usebenzisa lapho uthola imifino yokugcina imizuzu.

Sidinga ukuguqulwa kusuka ekuncikeni ezintweni lula, futhi kunalokho ukugxila ezenzweni ezincane ezibonisa ukunakekelwa komhlaba esiphila kuzo.
