Agro-residue Wastes as a Key to Unlocking Future Bio-energy Potentials

Abstract

Improvements in the search and utilisation of energy sources have unquestionably changed global lifestyle. Access to sufficient and sustainable energy is crucial for industrialisation as it plays a dynamic role in achieving economic domination and independence on the global stage. Extensive application of non-renewable fossil fuels gave rise to major environmental issues like increase in greenhouse gases and social costs of carbon. This has shifted the attention and dependence toward sustainable renewable energy resources. Amongst all, agricultural biomass remarks as the fourth largest contributor of renewable energy. Within developing countries like India, huge quantities of agricultural biomass are converted into valuable bioenergy. Agricultural, forestry, household, commercial and industrial residues and wastes constitute the raw material for bioenergy production. Recently, many developed countries with significant agricultural potential have attempted to harness their biomass resources to reduce their reliance on fossil fuels. Thus, the current chapter intends to evaluate the potential of agro-residue wastes for bioenergy production. Bioenergy derived from agricultural leftovers provides a practical and sustainable alternative to conventional approaches. Additionally, it can increase marginal and small farmer’s income and employment prospects. The present study focuses on providing comprehensive information about the production and utilisation of agricultural residues in different energy sectors. © 2025 selection and editorial matter, Adarsh Kumar, Saroj Kumar and Sheel Ratna; individual chapters, the contributors.
