Ukubaluleka kokugaywa kabusha kwamapulasitiki angcolile akukhona nje ukuguqula imfucuza ibe ingcebo, kodwa futhi kunokubaluleka okujulile nokuhle, okubonakaliswa ikakhulukazi ezicini ezimbili:
1. Umthelela welahla amapulasitikiemvelweni Ngenxa yentengo ephansi yamapulasitiki, asetshenziswa kakhulu ekufakweni kwemikhiqizo, futhi iningi lawo liyalahlwa ngemva kokusetshenziswa isikhathi esisodwa futhi libangele ukungcola okumhlophe okwaziwayo.Ngokwesibonelo, ukusetshenziswa kwefilimu yokumboza ngezitshalo yezolimo kuye kwaletha intuthuko enkulu kwezolimo, kodwa ukulahlwa kwezicucu ngemva kokusetshenziswa kubangela izingcezu zefilimu ukuba zivimbe inhlabathi, ewohloza izinga lezwe elilinyiwe, kuvimbela ukukhula kwezimpande zezitshalo nokumuncwa kwezitshalo. amanzi nezakhamzimba, ifake ushevu emhlabathini .Ukukhuculwa kwemfucuza yepulasitiki isikhathi eside yimvula kuzodala ukuthi izithasiselo ezinobuthi ezikumapulasitiki zingene emanzini angaphansi komhlaba, kubangele ukungcola emifuleni nasemachibini futhi kubeke engozini impilo yabantu!Ngakho-ke, izwe liphinde likhuthaze ngenkuthalo ubuchwepheshe bokugaywa kabusha kwepulasitiki kadoti, futhi imfucumfucu yokugaywa kabusha kwepulasitiki ingenye yezinketho.Ngokusebenzisa kabusha imfucuza yepulasitiki, ukuhlanza, ukuchotshozwa, ukuphelelwa amanzi emzimbeni nokomisa.
2 .Ubudlelwano phakathiudoti plastickabusha kanye namandla.Amapulasitiki esimanje ngokuyisisekelo ayimikhiqizo ye-petroleum, kodwa imithombo ye-petroleum yezwe lami yenza cishe amaphesenti amabili omhlaba kuphela.Kusukela ngo-1993, izwe lami selishintshile lisuka ekubeni elithengisa uwoyela laya ekubeni elingenisa uwoyela ezweni lonke .Ngo-2002, ithathe indawo yaseJapan njengomthengi wesibili omkhulu kawoyela emhlabeni.Kuze kube manje, ukuncika kukawoyela wezwe lami kwamanye amazwe sekufinyelele ku-40%.Ngakho-ke, ukushoda kwamandla sekuyinto enkulu evimbela ukuthuthukiswa komphakathi 1 futhi ukugaywa kabusha kwamapulasitiki alahlwayo kuzodambisa ukushoda okukhulu kwezinsiza ngokwezinga elithile.Kuze kube manje, ukukhiqizwa kwemikhiqizo yepulasitiki ezweni lami kubekwe endaweni yesibili emhlabeni, futhi kukhula ngezinga elingaphezu kuka-10% njalo ngonyaka, ngakho-ke inani lamapulasitiki angcolile akhiqizwa liyamangalisa.Kodwa-ke, isimo samanje sokugaywa kabusha kanye nokusetshenziswa kwamapulasitiki angcolile ezweni lami asikho ithemba.Amapulasitiki amaningi alahlwayo agcwaliswa phansi.
Kafushane, incazelo yomshini we-pellet wokubuyisela kabusha imfucumfucu inomgomo ofanayo nencazelo yokugaywa kabusha kwepulasitiki, futhi umshini we-plastic pelletizing uyindlela yokubona ukugaywa kabusha kwamapulasitiki angcolile.I-Plasic granulator ihlukaniswe yaba yi-screw granulator eyodwa kanye ne-twin screw granulator.I-single-screw granulator ingaphinda isebenzise ifilimu lepulasitiki, izikhwama ezilukiwe, imfucumfucu yentambo ye-rayon, ifilimu ye-greenhouse, njll., futhi i-twin-screw granulator ingaphinda isebenzise amabhodlela e-PET (amabhodlela esiphuzo sepulasitiki), njll.
