Kwiminyaka yakutshanje, imisebenzi yemveli ye-petrochemical kunye nemveliso yeekhemikhali iyaqhubeka nokusebenzisa izixhobo zefosili, kwaye imisebenzi yabantu ixhomekeke ngakumbi kwimithombo yefosili.Kwangaxeshanye, ukufudumala kwehlabathi nokungcoliswa kwendalo kuya kusiba yimibandela exhalabisa kakhulu uluntu.Ekubeni uphuhliso lwezoqoqosho lwemveli ikakhulu luxhomekeke kwimathiriyeli ekrwada yefosili, kodwa ngophuhliso lobomi, oovimba bemithombo yefosili engahlaziyekiyo bayancitshiswa ngokuthe ngcembe, imodeli yophuhliso loqoqosho lwemveli ayikwazanga ukuhlangabezana neemfuno zophuhliso zexesha elitsha.
Kwixesha elizayo, uqoqosho oluphambili luya kwamkela uphuhliso lwendalo, uphuhliso lohlaza kunye nokuhlaziywa kwemithombo njengemigaqo yophuhliso, kunye nokufezekisa iinjongo eziluhlaza, ezinekhabhoni ephantsi kunye nophuhliso oluzinzileyo.Ngokusekwe kwimeko yangoku yoqoqosho lwekhabhoni ephantsi, xa kuthelekiswa nemathiriyeli ekrwada yefosili.Izinto ezisekelwe kwi-bio-based ikakhulu zivela kwi-biomass evuselelekayo efana neenkozo, iimbotyi, i-straw, i-bamboo kunye nomgubo womthi, onokunciphisa kakhulu ukukhutshwa kwe-carbon dioxide kunye nongcoliseko lwendalo, kunye nokunciphisa ngokufanelekileyo uxinzelelo lokuchithwa kwemithombo ye-fossil.Kwikhabhoni ephantsi eluhlaza, ehambelana nokusingqongileyo, ugcino lwemithombo kunye nezinye iingenelo, imathiriyeli esekwe kwibhayoloji ngokuthe ngcembe iya kuba lolunye uphuhliso loqoqosho olusahlumayo olusakhulayo kunye nophuhliso lwenzululwazi nobuchwepheshe.
Ukuphuhliswa kwezinto ezisekelwe kwi-bio-based, ngelixa ukuhlangabezana neemfuno eziphathekayo kunye namandla abantu, akunakunciphisa kuphela ukusetyenziswa kunye nokusetyenziswa kwamandla e-fossil njengeoli kunye namalahle, kodwa nokunciphisa ukukhutshwa kwe-carbon dioxide, ngelixa uphepha ingxaki "yokukhuphisana. nabantu bokutya kunye nokutya komhlaba", yindlela esebenzayo yeshishini lepetrochemical ukuphumeza inguqu eluhlaza.Ukuze ukhokele ukuveliswa kunye nophuhliso loshishino lwemathiriyeli esekwe kwizinto eziphilayo ezisekwe kwi-biomass engeyiyo yokutya efana neentsalela zezityalo ezininzi kunye neentsalela, yenze nzulu ukudityaniswa kweshishini le-biochemical kunye neshishini lemichiza yemveli, ukudityaniswa kweshishini kunye nezolimo, ukusebenza okugqwesileyo kwemathiriyeli esekwe kwibhayoloji, ukunciphisa iindleko, ukonyusa iintlobo, ukwandisa usetyenziso, kunye nokuphucula inguqulelo yentsebenziswano, imveliso yesikali, kunye nomthamo wokungena kwimarike kushishino lwemathiriyeli esekwe kwibhayoloji.
