Developing word making their environment green by the cost environmental destruction in raw material producing county. Price of grain, vegetable oil are hiking as these items used for biofuel production and large number of people in developing countries failing to buy their basic needs. Intensive agriculture system followed for raw material production use high amount of fertilizers, pesticide herbicides which adversely affecting soil and water quality.
