Ukuthuthuka okusheshayo kwesayensi nobuchwepheshe manje kuletha izinto ezilula ezihlukene ezimpilweni zabantu, kodwa futhi kuletha izinkinga ezimpilweni zabantu.Ukusetshenziswa kobuchwepheshe obuphezulu kanye nokucekelwa phansi kwemvelo ngokweqile ngabantu kwenza izinkinga zemvelo zibe zimbi nakakhulu.Eminyakeni yamuva, zonke izigaba zokuphila ziye zanaka kakhulu ukuvikelwa kwemvelo.Manje abantu basebenzisa izikhwama zepulasitiki ezonakele ekuphileni kwabo kwansuku zonke, okuyinto entsha yokukhetha izikhwama zokupakisha ezinobungani bemvelo.
1. Yini isikhwama sepulasitiki esonakele?I-degradable isho ukubola kwamapulasitiki ngezindlela zobuchwepheshe ezinjengokuwohloka kwezithombe, i-oxidation kanye ne-biodegradation, ukuze kufezwe inhloso yokungangcolisi imvelo.Izikhwama zepulasitiki ezibolayo zenziwe ngezinto ezibolayo, ezingancibilika phakathi nenkathi ethile yesikhathi ngemva kokusetshenziswa.Izinto eziwohlokayo ziphinde zihlukaniswe zibe ezonakaliswe ngokuphelele futhi zonakaliswe kancane.
2. Ingabe izikhwama zepulasitiki ezibolile ziyabiza?Izinto ezikwazi ukuzuza ukucekelwa phansi kwengxenye kuphela zishibhile, ishibhile ngisho nangaphezu kwamapulasitiki ajwayelekile.Ngakho-ke, intengo yezikhwama zepulasitiki ezenziwe ngale nto iphansi kakhulu, kodwa ayikwazi ukufeza ukuwohloka okuphelele kwamapulasitiki.Izindleko zezinto ezingaboli ngokugcwele ziphakeme kakhulu.Uma kuyisikhwama sepulasitiki esenziwe ngepulasitiki ewohloka ngokuphelele, intengo izoba phezulu, kodwa ingama-yuan ayishumi kuphela noma ama-yuan ayisishiyagalombili ngenyanga.Iningi labantu lisazimisele ukukhipha le mali.
3. Ingabe izikhwama zepulasitiki ezonakele ziphephile?Abanye abantu bangase babe nalokhu kukhathazeka: izinto eziwohlokayo zincibilika kalula, khona-ke lapho ngisebenzisa izikhwama zepulasitiki ezonakele ekuphileni kwami kwansuku zonke, lapho ngithela udoti oshisa kakhulu emasakeni epulasitiki, izikhwama zepulasitiki zizolulaza ngokwazo Zilahlekile?Noma uvele uvuze imbobo enkulu?Eqinisweni, akudingeki ukhathazeke ngalokhu nhlobo, izinto eziwohlokayo zingonakaliswa ngaphansi kwezimo ezithile, njengezinga lokushisa nama-microorganisms.Ngakho-ke asikho isidingo sokukhathazeka ngokuthi izikhwama zethu zepulasitiki zizolulaza ngokwazo ngesikhathi sokusetshenziswa.
