Namhlanje i-biofuels isetyenziselwa imisebenzi ethile yezoqoqosho. Ezona zisetyenziswa kakhulu zezi i-ethanol kunye ne-biodiesel. Kuyaqondakala ukuba i-carbon dioxide gas ekhutshwa yi-biofuel ilungelelaniswe ngokupheleleyo kukufakwa kwe-CO2 eyenzeka nge-photosynthesis kwizityalo.
Kodwa kubonakala ngathi oku akunjalo kwaphela. Ngokwophando olwenziwe yiYunivesithi yaseMichigan Energy Institute ekhokelwe ngu UJohn DeCicco, ubungakanani bobushushu obugcinwe yi-CO2 obukhutshwa ngokutshiswa kwe-biofuels abukho kulingano kunye nenani le-CO2 elifunxwa zizityalo ngexesha lenkqubo yefotosinthesis njengoko izityalo zikhula.
Isifundo senziwe ngokusekwe kwidatha evela kwi- United States Isebe lezoLimo. Amaxesha aye ahlalutywa apho imveliso ye-biofuel yayiqinisa kwaye ukufunxwa kwe-carbon dioxide emissions kwizityalo kuphela kulungisa Iipesenti ezingama-37 ze-CO2 zizonke ezikhutshwayo Ngokutshisa ii-biofuels.
Iziphumo zezifundo zaseMichigan ziphikisa ngokucacileyo ukuba Ukusetyenziswa kwe-biofuel kuyaqhubeka nokwandisa inani le-CO2 ekhutshelwa emoyeni kwaye ayinciphanga njengoko bekucingwa ngaphambili. Nangona umthombo wokukhutshwa kwe-CO2 uvela kwi-biofuel enje nge-ethanol okanye i-biodiesel, ukukhutshwa komnatha kwiatmosfera kungaphezulu kunoko kufakwe zizityalo zezityalo, ke ngoko bayaqhubeka nokukhulisa ifuthe lobushushu behlabathi.
UJohn DeCicco wathi:
'Esi sisifundo sokuqala sokuvavanya ngononophelo ikhabhoni ekhutshiweyo emhlabeni apho kulinywa khona i-biofuels, endaweni yokucinga malunga nayo. Xa ujonga eyona nto yenzekayo emhlabeni, uyakufumanisa oko ayonelanga ngekhabhoni esuswa emoyeni ukuze ilungelelanise oko kuphuma kumbhobho womsila. "
