Umehluko phakathi kwezikhwama zamafilimu/amabhokisi esidlo sasemini kanye nemikhiqizo yepulasitiki yendabuko Eminyakeni yamuva nje, ngokuthuthukiswa kokuqwashisa ngemvelo, izikhwama zefilimu ezingabolikala namabhokisi okudla kwasemini kuye kwadonsa ukunaka kwabantu kancane kancane. Uma kuqhathaniswa nemikhiqizo yepulasitiki yendabuko,imikhiqizo engabolibanemehluko eminingi. Lesi sihloko sizoxoxa ngomehluko phakathi kwezikhwama zefilimu/amabhokisi esidlo sasemini angaboli kanye nemikhiqizo yepulasitiki yendabuko evela ezicini ezintathu: ukubola kwezinto eziphilayo, ukuvikelwa kwemvelo kanye nokuvunda.
1. Umehluko wokuwohloka kwezinto eziphilayo umehluko obaluleke kakhulu phakathi kwezikhwama zefilimu ezibolayo/amabhokisi okudla kwasemini kanye nemikhiqizo yepulasitiki yendabuko ukubola. Imikhiqizo yepulasitiki yendabuko ivamise ukusebenzisa i-petroleum njengempahla eluhlaza futhi kunzima ukuyehlisa. Imikhiqizo ebolayo ikhiqizwa ngezinto zemvelo ezivuselelekayo, njengesitashi, i-polylactic acid, njll., futhi inokonakala okuhle. Izikhwama zamafilimu/amabhokisi esidlo sasemini angaboliswa amagciwane endaweni yemvelo, ngaleyo ndlela kuncishiswe ukungcoliswa kwemvelo.
2. Umehluko ekuvikelweni kwemvelo Izikhwama zefilimu/amabhokisi esidlo sasemini angaboli anomthelela omncane endaweni ezungezile, ohluke kakhulu emikhiqizweni yepulasitiki yendabuko. Inqubo yokukhiqiza imikhiqizo yepulasitiki yendabuko izokhipha inani elikhulu le-carbon dioxide, ezoba nomthelela othile ekufudumeni komhlaba. Ngokuphambene, amanani amancane kakhulu e-carbon dioxide akhiqizwa ngesikhathi sokukhiqizwa kwemikhiqizo ebolayo. Ukusetshenziswa kwezikhwama zefilimu/amabhokisi esidlo sasemini angaboli angeke kubangele ukungcoliswa okukhulu kwemvelo futhi kuyisinqumo esivumelana nemvelo.
3. Umehluko wokuvundisa Esinye isici esibalulekile sezikhwama zefilimu ezibolayo/amabhokisi okudla kwasemini ukuvunda. Imikhiqizo yepulasitiki yendabuko inokuqina okuqinile futhi ayikwazi ukucekelwa phansi ama-microorganisms endaweni yemvelo, ngakho ayikwazi ukuhlanganiswa ngempumelelo. Ngokuphambene, izikhwama zefilimu ezibolayo/amabhokisi okudla angonakaliswa ngokushesha futhi agaywe ama-microorganisms futhi aguqulwe abe umanyolo wezinto eziphilayo ukuze anikeze umsoco emhlabathini. Lokhu kwenza izikhwama zefilimu/amabhokisi okudla abolayo abe yinketho eqhubekayo enomthelela omncane endaweni ezungezile.
4. Umehluko ekusetshenzisweni Kunomehluko othile ekusetshenzisweni phakathiizikhwama zefilimu/amabhokisi esidlo sasemini angabolikanye nemikhiqizo yepulasitiki yendabuko. Imikhiqizo ebolayo ijwayele ukuthamba endaweni enomswakama, inciphise impilo yayo yokusebenza, ngakho idinga ukugcinwa ngendlela efanele. Imikhiqizo yepulasitiki yendabuko inokuqina okuhle kanye nezindawo ezingangeni manzi futhi ifanele ukusetshenziswa isikhathi eside. Lapho ukhetha ukuthi yimuphi umkhiqizo ozowusebenzisa, ukucatshangelwa okuphelele kufanele kwenziwe ngokusekelwe ezidingweni ezithile kanye nezimo zokuwusebenzisa.
5. Umehluko ekuthuthukisweni kwezimboni Ukukhiqizwa nokudayiswa kwezikhwama zefilimu ezingaboli/amabhokisi okudla kwasemini kunamathuba amahle ebhizinisi namandla. Njengoba ukwanda kokuqwashisa ngemvelo emhlabeni wonke, abathengi abaningi ngokwengeziwe bakhetha ukusebenzisa imikhiqizo ebolayo. Lokhu kukhuthaze ukuthuthukiswa nokwanda kwezimboni ezihlobene, kwakha amathuba emisebenzi kanye nezinzuzo zomnotho. Uma kuqhathaniswa, imboni yemikhiqizo yepulasitiki yendabuko ibhekene nengcindezi ekhulayo futhi idinga ukukhula kancane kancane ngendlela evumelana nemvelo.
Ukufingqa, kunomehluko osobala phakathi kwezikhwama zefilimu/amabhokisi esidlo sasemini angaboli kanye nemikhiqizo yepulasitiki yendabuko mayelana nokubola, ukuvikelwa kwemvelo kanye nokuvundisa. Imikhiqizo ebolayo ephilayo ayibangeli nje kuphela ukungcoliswa kwemvelo okuncane, kodwa ingabuye iguqulwe ibe umanyolo wezinto eziphilayo futhi ibuyiselwe emjikelezweni wemvelo. Kodwa-ke, kunemikhawulo ethile ekusetshenzisweni kwemikhiqizo ebolayo. Ngokuvamile, ukukhetha ukuthi yimiphi imikhiqizo okufanele isetshenziswe kufanele kwenziwe ngokunengqondo ngokusekelwe ezidingweni zangempela nezimo zemvelo, futhi ukuqwashisa ngemvelo kanye nentuthuko eqhubekayo kufanele kukhuthazwe.
