CREATING A BIOFUEL WITH BOKASHI

다국어 초록 (Multilingual Abstract)

The purpose of the experiment was to investigate whether ethanol could be produced in a sustainable way to validate its use as an alternative fuel. This was tested by fermenting onions, apples, potato and cheese over a period of two weeks using Bokashi. The ethanol produced by the food was then collected and measured to determine which food yielded the most alcohol. To further test whether the food was a sustainable option, worms were added to the waste after the two weeks of fermenting. The purpose of this was to see whether they could survive in and condition the waste products into compost capable of growing crops. The results of the experiments suggest that onion was the most efficient at producing ethanol, followed by apple, potato and, finally, cheese, which did not ferment. All three fermentable foods that were tested managed to sustain worms for the entirety of the experiment, indicating that the food scraps remaining after fermentation could further be used as a compost to grow crops in. Furthermore, this could be done at a community level to increase the health of nearby farmlands and gardens, and to offer economic benefits for the production of ethanol.
