Amapulasitiki asekelwe ku-biozithola ukuduma kulezi zinsuku ngenxa ye-biodegradability yazo nezinsiza ezivuselelekayo.Amapulasitiki asekelwe ku-bio enziwe ngemithombo evamile efana nommbila, ubhontshisi wesoya kanye nomoba.Lezi zinto zisetshenziswa esikhundleni samapulasitiki kaphethiloli, anomthelela omkhulu ezinkingeni zemvelo emhlabeni namuhla.Kodwa-ke, inqubo yabo yokukhiqiza kanye nomthelela wemvelo, kanye nokusebenza nokusetshenziswa kwabo, kuseyinselele embonini.
Inqubo yokukhiqiza amapulasitiki asekelwe ku-bio ngokuvamile idinga isikhathi esiningi nomzamo kunepulasitiki evamile.Izinto ezingavuthiwe ezisetshenziselwa ukukhiqiza lawa mapulasitiki zithola ukusabela okuthile kwe-enzymatic noma amakhemikhali ukukhiqiza ukwakheka kwe-polymer oyifunayo.Ukwengeza, lezi zinqubo zivame ukubandakanya ukusetshenziswa kwamazinga okushisa aphezulu, okungathinta ikhwalithi yomkhiqizo wokugcina.Nokho, naphezu kwezinselelo ezibangelwa inqubo yabo yokukhiqiza,amapulasitiki asekelwe ku-bioziya ngokuya zisetshenziswa ukukhiqiza imikhiqizo ewusizo.
Enye yezinzuzo ezibalulekile zamapulasitiki asuselwa ku-bio umthelela wawo kwezemvelo.Amapulasitiki asekelwe ku-bio anokukhishwa kwegesi ebamba ukushisa ephansi kakhulu kunepulasitiki evamile.Ziyakwazi futhi ukubola, okusho ukuthi zihlukana zibe izingxenye zazo zemvelo phakathi nesikhathi esithile.Ngokwesibonelo,izikhwama zokudla, iziqukathi zokudla, amabhodlela, izitshafuthiizinkomishiezenziwe ngamapulasitiki asekelwe ku-bio zinikeza inketho eluhlaza ngoba zingavundiswa ngemva kokusetshenziswa.
Amapulasitiki asekelwe ku-bio nawo anezakhiwo eziyingqayizivele kanye nezicelo eziwenza alungele ukusetshenziswa okuhlukahlukene.Isibonelo, amapulasitiki asekelwe ku-bio ahlala isikhathi eside futhi alula kunepulasitiki evamile, okuwenza alungele ukukhiqizwa kwe-f.iziqukathi ze-od kanye nokupakisha.Ngaphezu kwalokho, amapulasitiki asekelwe ku-bio angabuye abunjwe abe yizimo ezihlukahlukene zezinhlelo zokusebenza ezahlukene.Lezi zakhiwo zizenza zibe enye indlela enhle kakhulu yamapulasitiki endabuko.
Naphezu kwezinzuzo ezinkulu zamapulasitiki asekelwe ku-bio, izinga labo lokutholwa lihlala liphansi kakhulu.Nokho, lo mkhuba uyashintsha.Isidingo seimikhiqizo esimeme kanye nemveloliyakhula, futhi ngenxa yalokho, izinkampani eziningi ngokwengeziwe zifuna ukufaka amapulasitiki endabuko ngezinketho ezisekelwe ku-bio.Ukwamukelwa kwamapulasitiki asuselwa ku-bio nakho kungaholela emathubeni amasha ezimakethe kanye nokuthuthukiswa kweimikhiqizo emisha.
Kafushane, isimo samapulasitiki asekelwe ku-bio embonini sishintsha ngokushesha.Naphezu kwezinselelo ezibangelwa inqubo yokukhiqiza kanye nomthelela wemvelo, amapulasitiki asekelwe ku-bio anikeza izinzuzo ezinkulu ezingenakuzitshwa.Izakhiwo zayo eziyingqayizivele kanye nokusetshenziswa kwayo kuyenza ibe enye indlela enhle kakhulu kumapulasitiki avamile, phakathi kwesidingo esikhulayo esivela kubathengi abafuna ukusebenzisa izinketho ezisimeme futhi ezinobungani bemvelo.Kusukaizikhwama zegrosa ezitsheni, amabhodlela, izitsha nezinkomishi, amapulasitiki asekelwe ku-bio afakazela ukubaluleka kwawo emakethe njengendlela engcono kakhulu kunepulasitiki evamile.
