DISADVANTAGE OF BIOETHANOL:
A) Bioethanol is easily evaporated hence can’t form a stable blend at higher percentages or use it in pure form.
B) At high concentration ethanol tend to absorb moisture thus cause wearing and tearing of engine.
C) Its normally seen that in cold temperature ethanol blend using vehicles seems to have starting trouble hence can’t be recommended to regions in near to poles which have snowy winters.
D) Both bio diesel and ethanol are produced from food crops. Hence here will de a clash of food crops as cash crops increasing food crisis and hunger deaths.
