Abstract:
On average, 435,000 metric tons of pineapples are produced annually in the Philippines, which is one of the country’s leading commercial fruit products. However, there are a lot of unused excess parts of the pineapple, notably the peelings, which are considered as waste and contribute to the country’s garbage problem.
There is a global oil crisis, as the demand for petroleum increases each year while our supplies are rapidly being depleted. Bioethanol, a principle biofuel, is a natural alternative to gasoline.
One solution to both dilemmas is to produce bioethanol from pineapple plant peelings. This will be made possible by extracting the glucose content of the peelings and fermenting it through the process of Simultaneous Saccharification and Fermentation (SSF) using the yeast sample. Peel samples, coming from Ananas comosus, will undergo a series of physical and chemical analyses to determine the glucose content, which will be utilized to yield bioethanol. The SSF process will be manipulated in terms of fermentation time and buffer level used to determine the best variables for biofuel production.
