A Proposed Project of Microbial Fuel Cell Using Food Waste

Vol.4, No.1

Abstract

Food waste occurs when edible goods are thrown at any point along the food chain. Food
waste occurs everywhere, including households, restaurants, fast food chains, and other
areas. Every year, around 1.3 billion tons of food are wasted, which is comparable to more
than half of the world's entire cereal production. Microbial fuel cells (MFCs) are a form of
bioelectrochemical system (BES) that uses bacteria to generate power by producing electrons
within their cells and transferring them across their cell. It is also useful in situations where
waste, such as food and water waste, can be used to generate power through the use of
microorganisms.

The results of the study in terms of construction materials, procedures, effectiveness, and
presentation, as observed by the two groups of respondents, chemical engineers, and food
technologists, are accepted. It indicates that there is no significant difference between the two
groups of respondents on the level of acceptability assessment of Microbial Fuel Cells using
Food Waste in terms of construction materials, procedures, effectiveness, and presentation.

For further enhancement and improvement of the project, the ensuing discussions and the
recommendations proposed are as follows: collect and store the food waste as soon as
possible to be able to produce microbes and be less time-consuming. The respondents also
recommend using materials that can resist corrosion due to the food residue and looking into
other possible container materials that may reduce plastic waste. Moreover, they recommend
conducting this experiment in a laboratory to avoid contamination and ensure health protocols
as well. Lastly, do the experiment for 3 or 2 months because it will only be able to light up a
small LED after two months.
