Bioethanol Extraction and Its Production from Agricultural Residues for Sustainable Development

Bioethanol is a reasonable alternative option, its generation from readily available in an enormous amount and eco-friendly bio-resources, i.e., agricultural residues, one of the most suitable and renewable alternative options in place of fossils fuels resources, which being to deplete in an upcoming day. According to the recent statistical analysis report of Economic Co-operation and Development (OECD) and the Food and Agriculture Organization (FAO), for the 2017–2026 year, discussed the cereal feedstocks availability like Wheat and Rice across the world for biofuel production. Wheat and rice cereal cops contribute approximately, 742 Mt and 495 Mt million hectares annually, instead of other cereal crop residues such as Pearl millet (Pennisetum glaucum), Barley (Hordeum vulgare), Gram pea (Cicer arietinum), Sugarcane (Saccharum officinarum), and Great millet (Sorghum vulgare), abundantly available in Asian countries only. Instead of agricultural residues, municipal sewage waste (MSW) can also be utilized as organic biomass for bioethanol production in Mediterranean countries. As per advanced technologies concern, all of these are described in this chapter, they are direct combustion, combustion after physical processing, thermo-chemical and biological processing followed by the simultaneous saccharification and co-fermentation (SSCF) and consolidated bioprocessing (CBP). In addition, other applications of recycled wastes were also discussed. The foremost aim of the chapter was too focused on the latest development with respect to technologies related to the biofuel sector and sustainable development of the agricultural sector as well.
