Disclosed is a preparation method for bio-fuel materials and bio-chemicals comprising the following steps: preparing a medium comprising fermentation waste generated in an alcohol production process; inoculating a first microorganism into the medium; and culturing the medium wherein the first microorganism was inoculated. More specifically, the preparation method for bio-fuel materials and bio-chemicals comprises the following steps: fermenting hexoses from a mixture of pentoses and hexoses to produce an ethanol fermentation broth; separating and purifying the ethanol fermentation broth; preparing a medium comprising the fermentation waste produced in the separation and purification step; inoculating a first microorganism into the medium; and culturing the medium wherein the first microorganism was inoculated.

Disclosed is a method of manufacturing a glycerol carbonate (GC). The method includes a bio-catalyst reaction for generating the GC and byproducts generated by reacting a reactant solution using a lipase of a bio-catalyst. In this instance, the reactant solution is prepared by adding glycerol, a glycerol-containing composition, or a dimethyl carbonate (DMC) in a reaction solvent.
