“…National Policy on Biofuels formulated by the Ministry of New and Renewable Energy (MNRE) in 2009 recommended the blending at least 20% biofuels with diesel and petrol by 2017. Ethanol blending will increase the bioethanol requirement to 3.4 billion liters by 2020 [35]. As the present requirement of ethanol for the potable and chemical sector is fulfilled solely by molasses, to suffice the above need of blending there is a need to cultivate 20-23% more sugarcane (to generate molasses) than what is the present requirement of the sugar industry.…”

Sustainable Biofuels Development in India

Biofuels are regarded as one of the most promising options to fulfill the higher energy requirement in future and simultaneously decarbonize the environment caused by excessive usage of fossil fuels. Technologies for the production of biomass based fuels particularly bioethanol and biodiesel are rapidly developing. However, successful commercialization of biofuels is still far due to high capital and operation expenditures and technical immaturities at large operations. Biofuel policies from major biofuels supporting nations might capitalize rural economic development and sustainable agricultural growth after strongly promoting biofuels. India has a biofuel policy, which foresees biofuels as potential candidates stimulating rural development by generating employment opportunities, together with environmental and economic benefits. The biofuel industrial sector has shown promising results and could serve as a potential source of substantial employment in near future. However, for the successful incorporation of biofuel policy, sustainable key indicators encompassing social and economic factors need to be evaluated properly in different scenarios. This chapter discusses the biofuel policies, key sustainable indicators, socioeconomic aspects of biofuels in Indian perspective.

“…Sweet sorghum (Sorghum bicolor) is a C 4 crop and is considered as one of the most important food and fodder crops in arid and semiarid regions of the world [6]. This crop occupies approximately 45 million ha in Africa and India, accounts for >80% of the global cultivated area.…”

“…Although sweet sorghum has been suggested as a potential crop for bioethanol production in developing countries [6,17,18], but it is still acknowledged as a new crop in many countries. To earn permission for cultivation in a large area for bioethanol production, the cultivation protocol for this crop should be critically examined.…”

Sweet sorghum (Sorghum bicolor) is a promising alternative crop for bioethanol production in developing countries. However, to extend the cultivative area of this crop, it needs to develop an appropriate growing protocol for farmers. This chapter describes the examination of different doses of fertilizers combined with manure and micronutrients, in various applied times, on biomass, sugar content and ethanol production of sweet sorghum. It was observed that the application of 90 N + 90 P 2 O 5 + 60 K 2 O provided maximum stem yield and optimum contents of sugar and ethanol yield, however nontreatment of any among P, P 2 O 5 and K 2 O caused significant reduction of biomass and ethanol production. Higher fertilization >90 N may provide greater productivity of this crop but it may cause lodging and economic deficit for farmers in developing countries. It was also found that the applied times of fertilization should be at 3-4 to 7-8 leaf stage. In contrast, when the fertilization was as close to the flowering stage caused remarkable reduction of stem yield and ethanol production. The supplementation of (NH4) 2 MO 7 O 2 .4H 2 O at 5 kg/ha provided an increase of 10-12 tons/ha of stem yield and a remarkable enrichment of ethanol production. Findings of this study are useful for farmers and agricultural extensionists to promote biomass and ethanol productivity of this crop for bioethanol production. This research also highlights a greater possibility of exploiting sweet sorghum cultivation in infertile and hilly, abandoned areas for ethanol production.

“…According to Basavaraj et al [60], meeting the 10 percent blending would require using 10.5 million hectares of productive land and producing 736.5 million tons of sugarcane, which are twice as the current area and volume of production. Considering the problem of water scarcity in India, the water requirement (i.e., 20,000-30,000 m 3 ) for producing per hectare of sugarcane will limit the potential for expanding production [60]. Moreover, the lack of technological inputs and infrastructures are considered the major hurdles for implementing such intervention.…”

“…This acquires further importance in the context of South Asian Enigma of stagnant per-capita food consumption (compared to North Africa and West Asia) despite impressive growth registered in terms of per-capita income. In case of ethanol blending, achieving a 10 percent blending will be difficult due to the demand for alcohol from the potable and chemical sector, which is growing at 3-4 percent per annum, and the highest available alcohol from molasses set at 2.3 billion liters [60]. However, the government increased the blending targets from 5 to 10 percent in 2015 [61].…”

This paper discussed the analysis of the survey on sustainability of bioenergy conducted in the Philippines, India and China. It acquired general perceptions of the people by asking them (a) specific questions about their level of familiarity with bioenergy; (b) relationship of their work to bioenergy; and (c) their opinion on contribution of various feedstock on the economy and impact of bioenergy production on food security. In addition to these questions, we estimated preference weights of various feedstock based on the conjoint choices on bioenergy's contribution to social stability, social welfare and ecological balance. The estimates revealed significant trade-offs not only among these three dimensions of sustainability but also the relative importance of energy security, food security and ecosystem capacity to other economic, social and environmental objectives. The types of first generation feedstock that are currently used for biofuel production in the respective countries and those that offer alternative household use are perceived as important to the economy and preferred bioenergy feedstock. Based on the results of the study, the preferred role of bioenergy for sustainable development reflects the social and economic concerns in the respective Asian countries, e.g., energy security in China, food security in India, and ecosystem degradation in the Philippines.
