Ngokuthuthuka okuqhubekayo kokuqwashisa ngemvelo, imboni yezimonyo iphinde yaletha inguquko eluhlaza ekupakisheni. Ukupakishwa kwepulasitiki okusekelwe ku-petroleum evamile akudli nje kuphela izinsiza eziningi ngesikhathi sokukhiqiza, kodwa futhi kubangela ukungcoliswa kwemvelo okukhulu ngesikhathi sokwelashwa ngemva kokusetshenziswa. Ngakho-ke, ukuhlola izinto zokupakisha ezisimeme sekuyindaba ebalulekile embonini yezimonyo.
Amapulasitiki asekelwe ku-petroleum
Amapulasitiki asekelwe ku-petroleum awuhlobo lwempahla yepulasitiki eyenziwe ngamafutha ezinto ezimbiwa phansi njenge-petroleum. Inepulasitiki enhle kanye nezakhiwo zemishini, ngakho-ke isetshenziswa kabanzi emikhakheni ehlukahlukene. Ikakhulukazi, amapulasitiki asuselwa ku-petroleum afaka izinhlobo ezilandelayo ezijwayelekile:
I-Polyethylene (PE)
I-Polypropylene (PP)
I-Polyvinyl chloride (PVC)
I-Polystyrene (PS)
I-Polycarbonate (PC)
Amapulasitiki asuselwa ku-petroleum abusa ukupakishwa kwezimonyo ngenxa yokungasindi kwawo, ukuqina kwawo kanye nokusebenza kahle kwezindleko. Amapulasitiki asekelwe ku-petroleum anamandla aphezulu kanye nobulukhuni, ukumelana okungcono kwamakhemikhali kanye nokucutshungulwa okungcono kunoplastiki bendabuko. Nokho, ukukhiqizwa kwalokhu kudinga inani elikhulu lemithombo ye-petroleum, okwandisa ukuwohloka kwemithombo yomhlaba. Ukukhishwa kwe-CO2 okukhiqizwa phakathi nenqubo yokukhiqiza kuphezulu futhi kunomthelela othile emvelweni. Ngesikhathi esifanayo, ukupakishwa kwepulasitiki kuvame ukulahlwa ngokungahleliwe ngemva kokusetshenziswa futhi kunzima ukwehlisa ngemva kokungena endaweni yemvelo, okubangela ukulimala okukhulu emhlabathini, imithombo yamanzi kanye nezilwane zasendle.
Izixazululo zokuklama ezintsha zokupakisha okusimeme
Ipulasitiki egaywe kabusha
Ipulasitiki egaywe kabusha iwuhlobo olusha lwezinto ezenziwe ngamapulasitiki alahlwa ngezinqubo ezinjengokuchotshozwa, ukuhlanza, nokuncibilikisa. Inezakhiwo ezifanayo nepulasitiki emsulwa, kodwa isebenzisa izinsiza ezimbalwa kakhulu ekukhiqizeni kwayo. Ukusebenzisa amapulasitiki agaywe kabusha njengezinto zokupakisha zezimonyo akukwazi nje ukunciphisa ukuncika ezinsizeni ze-petroleum, kodwa futhi kunciphise ukukhishwa kwekhabhoni ngesikhathi senqubo yokukhiqiza.
I-Bioplastics
I-Bioplastic iyimpahla yepulasitiki ecutshungulwa kusukela kumithombo ye-biomass (njengesitashi, i-cellulose, njll.) ngokusebenzisa ukuvutshelwa kwezinto eziphilayo, ukuhlanganiswa nezinye izinqubo. Inezici ezifanayo nepulasitiki yendabuko, kodwa inganciphisa ngokushesha endaweni yemvelo futhi ihambisana nemvelo. Izinto zokusetshenziswa ze-bioplastics zivela emithonjeni ehlukahlukene, okuhlanganisa utshani bezitshalo, imfucumfucu yezinkuni, njll., futhi zivuseleleka kakhulu.
Ezinye izinto zokupakisha
Ngaphezu kwamapulasitiki agaywe kabusha kanye nama-bioplastics, ziningi ezinye izinto ezisimeme zokupakisha ezitholakalayo. Isibonelo, izinto zokupakisha zephepha zinezinzuzo zokungasindi, ziphinde zisebenziseke futhi ziboleke, futhi zifanele ukusetshenziswa ekufakweni kwangaphakathi kwezimonyo. Nakuba izinto zokupakisha zengilazi zisinda kakhulu, zinokuqina okuhle kakhulu nokusebenziseka kabusha futhi zingasetshenziselwa ukupakisha izimonyo ezisezingeni eliphezulu. Ngaphezu kwalokho, kukhona izinto ezintsha eziyinhlanganisela ye-bio-based, izinto eziyinhlanganisela yensimbi, njll., ezihlinzeka nokukhetha okwengeziwe kokupakishwa kwezimonyo.
Amabhrendi nabathengi ngokuhlanganyela bathola intuthuko esimeme
Ukuzuza ukuthuthukiswa okusimeme kokupakishwa kwezimonyo kudinga imizamo ehlanganyelwe yemikhiqizo nabathengi. Mayelana nemikhiqizo, izinto zokupakisha ezisimeme kanye nobuchwepheshe kufanele buhlolwe futhi busetshenziswe ukuze kuncishiswe umthelela omubi wokupakisha endaweni. Ngasikhathi sinye, imikhiqizo kufanele futhi iqinise imfundo yezemvelo kubathengi futhi iqondise abathengi ukuthi basungule imiqondo yokusetshenziswa kokuluhlaza. Abathengi kufanele banake izinto zokupakisha zemikhiqizo futhi babeke kuqala imikhiqizo enokupakishwa okusimeme. Ngesikhathi sokusetshenziswa, inani lokupakisha elisetshenzisiwe kufanele lincishiswe ngangokunokwenzeka, futhi ukupakishwa kwemfucuza kufanele kuhlukaniswe ngendlela efanele futhi kulahlwe.
Ngamafuphi, inguquko eluhlaza yokupakishwa kwezimonyo iyindlela ebalulekile yokuthi imboni yezimonyo izuze intuthuko esimeme. Ngokwamukela izinto zokupakisha ezisimeme kanye nobuchwepheshe kanye nokuqinisa imfundo yezemvelo, amabhrendi nabathengi bangaba negalelo ngokuhlanganyela ekusaseni leplanethi.
