Abstract
The use of corn for ethanol production is a pertinent issue in the transportation and fuel industry as well as an issue for the economy and environment, being used in greater demand for ethanol production than for feedstock. A shift towards second generation biofuels, created using non food biomass, such as orange peels, is arguably a necessary change. This experiment was conducted to confirm ethanol production from orange peels, and it was hypothesized that undistilled orange peels that are fermented, would be capable of producing ethanol due to the essential oils present in the peels, specifically D-limonene. For the experiment, the undistilled orange peels were fermented along with distilled orange peels for comparison. Twelve bottles were used with orange peel powder (OPP) percentages of 5, 10, and 20 percent. It was found that fermented orange peels were capable of producing ethanol, measured in alcohol-by-volume (ABV), for all of the trials. The results more importantly showed that there was a difference between the ABV of the distilled and undistilled bottles of OPP and that the undistilled OPP bottles produced more ethanol. /
