Conversion and Utilization of Farm Agro-Waste to Sustainable Energy Production: A Waste to Wealth Approach

India’s economy relies heavily on agriculture, and the country’s favorable climate makes it possible to cultivate a wide variety of crops around the year. This results in an abundance of farm agricultural wastes, which has huge potential for its utilization. Similarly, the waste generated from other activities cultivation activities, aquaculture waste, poultry waste, agro-industrial waste, etc. also has the scope to generate wealth. If these wastes are not disposed of/utilized scientifically they can impose severe impacts on human health and the environment. Economic and sustainable management of farm agricultural wastes via technical interventions such as composting, recycling, biofuel production, electricity generation, vermicomposting, etc. may lead to the generation of additional income for farmers and entrepreneurs. This chapter explores various technologies and strategies employed to convert farm agro-waste into valuable energy resources, highlighting their benefits, challenges, and potential for widespread adoption. It provides an overview of the waste-to-wealth approach, emphasizing the importance of sustainable energy production from agricultural waste for achieving a circular economy and mitigating climate change. The bulk of this chapter is made over two parts that are (a) detailed analysis of categories of available farm agro-waste, which is carried out to understand the quantum and properties of available waste and (b) suitable approaches for its utilization for sustainable energy generation. It aims to provide researchers, policymakers, and stakeholders with valuable insights into the waste-to-wealth approach, highlighting its potential for promoting a circular economy, reducing environmental impacts, and creating economic opportunities in the agricultural sector.
