Agriculture has been the dominant sector of India’s Gross Domestic Product. Contribution by agriculture and other allied sectors is pegged at more than Rs 18 lakh crore in FY19. Crop Residue Management is a challenge for the farmers all across the nation. From the total residue produced in the country, nearly 99.2 MT is burnt at the farm, of which more than 60% is by rice and wheat. Lack of traditional use of residue, clearing the field in short time to sow the next crop in time leads to stubble burning. Stubble burning has become a major pollutant lately. Burning crop residue is a crime under the Air Pollution Control Act of 1981. Although, government’s execution lacks firmness, thus encouraging finding the alternatives. One such process is Torrefaction. This agricultural waste can be efficiently utilized for the purposes which currently are being served by coal based power plants, with additional advantage of residue management. In this work, effect of torrefaction on rice stubble, and the physiochemical properties are discussed. Results so obtained are conducive in designing feasible logistic studies, and more applications of farm based agricultural residue. The torrefaction behaviors of the agricultural residues from plains of North India of rice straw were investigated, and the torrefaction process carried on them resulted in a proof that the torrefied biomass of plant origin has energy potential and calorific value equivalent to that of conventional fossil fuels. This paves way for deploying the process of torrefaction in sustainable energy generation.
