Ukugaywa kabusha kwamapulasitiki kusiza ukwehlisa umthwalo endaweni ezungezile, kodwa amapulasitiki amaningi (91%) ayashiswa noma alahlwe ezindaweni zokulahla imfucuza ngemva kokusetshenziswa kanye kuphela.Izinga lepulasitiki liyehla isikhathi ngasinye lapho ligaywa kabusha, ngakho-ke akwenzeki ukuthi ibhodlela lepulasitiki liguqulwe libe elinye ibhodlela.Nakuba ingilazi ingagaywa kabusha futhi isetshenziswe kabusha, ayihambisani nemvelo.Ingilazi yenziwe ngezinto ezingavuseleleki okuhlanganisa i-limestone, i-silica, umlotha wesoda noma isihlabathi esiwuketshezi.Imayini ye-limestone ilimaza indawo ezungezile, ithinta amanzi angaphansi nangaphezulu, yandisa amathuba ezikhukhula, ishintsha izinga lamanzi, futhi iphazamise ukugeleza kwamanzi emvelo.

I-Aluminium ingaphinda igaywe kabusha futhi igaywe kabusha unomphela, kodwa i-aluminium eningi ebalulekile iphelela ezindaweni zokulahla imfucumfucu lapho kuthatha iminyaka engu-500 ukubola.Ngaphezu kwalokho, umthombo oyinhloko we-aluminium i-bauxite, ekhishwa enqubweni yokucekela phansi indawo ezungezile (kuhlanganise nokumba izindawo ezinkulu zomhlaba nokugawulwa kwamahlathi), okubangela ukungcola kothuli.

Iphepha namakhadibhodi yiwona kuphelaizinto zokupakishaetholakala ezinsizeni ezivuselelekayo ngokuphelele.Izihlahla eziningi ezisetshenziselwa ukwenza iphepha ziyatshalwa futhi zivunwe ngale njongo.Ukuvuna izihlahla akusho ukuthi kubi endaweni ezungezile.Izihlahla zidla i-carbon dioxide eningi, ngakho-ke lapho izihlahla zitshalwa futhi zivunwa, yilapho i-CO2 idliwa kakhulu futhi kukhiqizwa umoya-mpilo owengeziwe.

Ukungapakishi kulungile, kodwa kunzima ukukwenza.Ukuzama ukuthenga imikhiqizo engapakishwanga, izikhwama ezibolayo noma ukuletha ezakho izikhwama kungaba lulaeco-friendlyizinto ezincane okumele uzenze.
