Eco Factor: Juice extracted from waste watermelons to be used in biofuel production.
Producing biofuel from food crops has been regularly criticized as a waste of precious resources such as water. A new research says that other than growing food crops especially for biofuel production, waste from certain food items including watermelons can be used to produce the same fuel.
According to a research, an estimated 20% of the annual watermelon crop isn’t suitable for sale because of blemishes or unusual shapes. However, watermelon juice contains about 10% directly fermentable sugars and about 35 umol/ml of free amino acid, which can be fermented to produce bioethanol.
