Title : Sweet Sorghum: A Brief Study on a Smart Crop

Abstract :

The policy of the Government of India to reduce pollution and fuel-import cost by blending up to 20% ethanol and 80% gasoline as an automotive fuel which came into force 8 March 2021 [29]. In India there is continuous demand of alternative fuels to produce bioethanol from various feedstock’s. Currently, alcohol is produced only with molasses as the only feedstock. In addition, molasses also costs from Rs. 2000 to Rs. 5000 ton-1 excluding the cost of producing ethanol from molasses, which also varies. In addition, the ethanol production process is also not good for the environment because molasses also comes from the sugar industry as a byproduct. The sweet sorghum can accumulate up to 20% of sugars in its stalks [17] and can be a great alternative as a feedstock with minimal crop duration and water requirement as compared to sugarcane which is used to extract molasses. After extracting sweet sorghum juice, the bagasse contains higher calorific content. Hence, it can generate around 3.25 MW ha-1 of electricity [18]. In addition, several countries are looking for the steps to boost sweet sorghum’s production. Since stalk juice will only be used for producing ethanol, it will not affect food security. According to the Planning Commission of India, sweet sorghum is the best alternative to molasses for producing ethanol without affecting the environment in India [19, 20]. This article is aimed to explore the environmental and economical benefits of sweet sorghum and some challenges in ethanol production by conducting research on various studies and to find out the best steps that the Government of India can take to save the environment while fulfilling energy needs.
