Ososayensi benze inqubekelaphambili ebalulekile emkhakheni wamapulasitiki angaboli, okuyisinyathelo esibalulekile sokuvikela imvelo.Ithimba labacwaningi abavela enyuvesi ehlonishwayo lenze ngempumelelo uhlobo olusha lwepulasitiki oluwohloka phakathi nezinyanga, lunikeze ikhambi elingaba khona enkingeni ekhulayo yokungcoliswa kwepulasitiki.
Imfucumfucu yepulasitiki isiyinkinga ephuthumayo yomhlaba wonke, futhi amapulasitiki endabuko athatha amakhulu eminyaka ukubola.Lokhu kuphumelela kocwaningo kunikeza inhlansi yethemba njengoba amapulasitiki amasha abolayo enikeza ezinye izindlela ezisebenzayo kumapulasitiki angaboli wendabuko adala umonakalo olwandle, izindawo zokulahla imfucumfucu kanye nemvelo.
Ithimba labacwaningi lisebenzise inhlanganisela yezinto zemvelo kanye ne-nanotechnology ethuthukisiwe ukuze lenze le mpumelelo yepulasitiki.Ngokuhlanganisa ama-polymer asekelwe esitshalweni kanye nama-microbes enqubweni yokukhiqiza, bakwazile ukwakha ipulasitiki engahlukaniswa ibe izinto ezingenabungozi ezifana namanzi ne-carbon dioxide ngokusebenzisa izinqubo zemvelo eziphilayo.
Inzuzo enkulu yale pulasitiki esanda kuthuthukiswa ebolayo isikhathi sayo sokubola.Nakuba amapulasitiki endabuko angahlala amakhulu eminyaka, le pulasitiki emisha yonakala phakathi nezinyanga ezimbalwa, inciphise kakhulu umthelela wayo oyingozi emvelweni.Ngaphezu kwalokho, inqubo yokwenziwa kwaleli pulasitiki libiza izindleko futhi lizinzile, okwenza kube enye indlela esebenzayo ezimbonini ezihlukahlukene.
Izinto ezingase zibe khona zaleli pulasitiki elibolayo zinkulu kakhulu.Ithimba labacwaningi libona ngeso lengqondo ukusetshenziswa kwalo emikhakheni eyahlukene, okuhlanganisa ukupakisha, ezolimo kanye nezimpahla zabathengi.Ngenxa yesikhathi esifushane sokuphumula, ipulasitiki ingabhekana ngokuphumelelayo nenkinga yemfucumfucu yepulasitiki enqwabelana ezindaweni zokulahla imfucumfucu, evame ukuthatha indawo yezizukulwane ngezizukulwane.
Isithiyo esibalulekile ithimba labacwaningi elisinqobe ngesikhathi sokuthuthukiswa kwaba amandla nokuqina kwepulasitiki.Esikhathini esedlule, amapulasitiki abolayo ayejwayele ukuqhekeka futhi ayengenakho ukuqina okudingekayo ukuze asetshenziswe isikhathi eside.Kodwa-ke, ngokusebenzisa i-nanotechnology, abacwaningi bakwazi ukuthuthukisa izakhiwo zemishini yepulasitiki, baqinisekisa amandla nokuqina kwayo ngenkathi begcina ukubola kwayo.
Nakuba le mpumelelo yocwaningo iyathembisa, izithiyo ezimbalwa zisadinga ukunqotshwa ngaphambi kokuba le pulasitiki yamukelwe ngezinga elikhulu.Ukuqinisekisa ukusebenza kanye nomthelela wesikhathi eside wepulasitiki, ukuhlolwa okwengeziwe nokucwengwa kuyadingeka.
Noma kunjalo, lokhu kuphumelela ocwaningweni lwepulasitiki olungaboli kunikeza ithemba ngekusasa eliluhlaza.Ngomzamo oqhubekayo nokusekelwa, le ntuthuko ingase iguqule indlela esibhekana ngayo nokukhiqizwa kwepulasitiki, ukusetshenziswa kanye nokulahlwa, kube negalelo elikhulu ekuxazululeni inkinga yomhlaba wonke yokungcoliswa kwepulasitiki.
