Ukurisayikilisha iiplastiki kunceda ukunciphisa umthwalo kokusingqongileyo, kodwa uninzi (91%) iiplastiki ziyatshiswa okanye zilahlwe kwiindawo zokulahla inkunkuma emva kokusetyenziswa kanye kuphela.Umgangatho weplastiki uyehla rhoqo xa iphinda isetyenzisiwe, ngoko ke akunakwenzeka ukuba ibhotile yeplastiki iguqulwe ibe yinye ibhotile.Nangona iglasi inokuphinda isetyenziswe kwaye isetyenziswe kwakhona, ayihambelani nokusingqongileyo.Iglasi yenziwe ngezinto ezingahlaziyekiyo eziquka ilitye likalikalika, isilica, uthuthu lwesoda okanye isanti engamanzi.Ukwembiwa kwekalika kuyonakalisa indalo esingqongileyo, kuchaphazela amanzi asemhlabeni nangaphezulu, kwandisa amathuba okukhukula, kuguqula umgangatho wamanzi, kwaye kuphazamise ukuhamba kwamanzi endalo.

I-aluminiyam inokuphinda isetyenziswe kwaye isetyenziswe ngokungenasiphelo, kodwa i-aluminiyam eninzi enexabiso iphelela kwiindawo zokulahla inkunkuma apho kuthatha iminyaka engama-500 ukubola.Ngaphezu koko, owona mthombo we-aluminiyam yi-bauxite, ekhutshwa kwinkqubo yokutshabalalisa indalo (kuquka ukugrumba iindawo ezinkulu zomhlaba kunye nokutshatyalaliswa kwamahlathi), okubangela ukungcola kothuli.

Iphepha kunye nekhadibhodi kuphelaizinto zokupakishaevela kwimithombo ehlaziyekayo ngokupheleleyo.Uninzi lwemithi esetyenziselwa ukwenza iphepha ityalwa kwaye ivunelwe le njongo.Ukuvuna imithi akuthethi ukuba kuyingozi kwimekobume.Imithi itya kakhulu i-carbon dioxide, ngoko okukhona imithi ityalwa kwaye ivunwa, kokukhona i-CO2 ityiwa kwaye i-oksijini eninzi iveliswa.

Ukungapakishi kulungile, kodwa kunzima ukwenza.Ukuzama ukuthenga iimveliso ezingapakishwanga, iibhegi ezinokubola okanye uze nezakho iibhegi kunokuba lulaeco-friendlyizinto ezincinci ukwenza.
