Iplastiki ebolileyo elaminethiweyo eplastikini ebolileyo ...

Imigaqo yokubola kweeplastiki ezinokubola yahlulwe ngokwe-photodegradation, biodegradation kunye nokubola kwamanzi, njl. Okwangoku, ukubola kweentsholongwane kwimeko yokwenza umgquba yeyona ndlela iphambili. Iquka kakhulu isitatshi. Kwimeko yokwenza umgquba, yahlulwe ibe yi-carbon dioxide namanzi ziintsholongwane, nto leyo ephucula ngempumelelo ukuchuma komhlaba kwaye isombulule ingxaki yongcoliseko olumhlophe oluvela kumthombo.
I-Polylactic acid (PLA) luhlobo olutsha lwezinto ezinokubola ezenziwe ngezinto eziluhlaza ezenziwe ngesitatshi ezicetywayo zizityalo ezihlaziyekayo ezifana nombona. Inokubola kakuhle, kwaye inokonakala ngokupheleleyo ziintsholongwane ezikwindalo emva kokusetyenziswa, ekugqibeleni ivelise i-carbon dioxide namanzi, ngaphandle kokungcolisa okusingqongileyo, nto leyo eluncedo kakhulu ekukhuseleni okusingqongileyo kwaye ibonwa njengezinto ezinobuhlobo nokusingqongileyo.
Iingxowa zempuphu zihlala zisetyenziselwa ukupakisha ulwelo, njengeejusi, iziselo, iisepha, ubisi, ubisi lwesoya, isosi yesoya, njl. Njengoko iingenelo zokupakisha okuguquguqukayo okunomlomo ziqondwa ngabathengi abaninzi, kwaye ngokuqiniswa okuqhubekayo kolwazi lokhuseleko lokusingqongileyo, kuya kuba ngumkhwa wokusebenzisa ukupakisha okuguquguqukayo okunomlomo ukutshintsha iibhareli, kunye nokusebenzisa ukupakisha okuguquguqukayo okunomlomo ukutshintsha ukupakisha okuguquguqukayo kwendabuko okungenakuphinda kuvalwe. Eyona nzuzo inkulu yeengxowa zempuphu kuneendlela zokupakisha eziqhelekileyo kukuthwala. Ingxowa yomlomo inokufakwa ngokulula ebhegini okanye epokothweni, kwaye ububanzi beshishini lomzi-mveliso wethu buneempawu zokwahlukahluka ngokunciphisa umxholo.
Izinto ezibolayo zinokunciphisa kakhulu iingxaki zongcoliseko lokusingqongileyo. Zinegalelo elikhulu ekukhuselweni kokusingqongileyo.
Ayinakunciphisa nje kuphela ukukhutshwa kwegesi eyingozi, kodwa ikwaphucula umhlaba njengesichumiso sendalo. Ke ngoko, uphuhliso lweengxowa zemilomo ezinokonakala ezingcolisa indalo kufuneka luphuhliswe ngendlela yokwenza umgquba ukuze luhlangabezane neemfuno zizonke zentsimi yokukhusela indalo. Iingxowa zemilomo ezinokonakala indalo zinokunciphisa ngempumelelo kwaye zithintele ungcoliseko lwendalo, kodwa itekhnoloji yazo yemveliso kunye nokusasazwa kunye nokusetyenziswa kwazo kusafuna uphuhliso olongezelelekileyo, olubaluleke kakhulu ekusetyenzisweni kwamandla kunye nokukhuselwa kwendalo.
