Assessing the techno-economic and sustainable potential of chemical looping for bioenergy production from organic solid wastes

Abstract

Organic solid waste from municipal, agricultural, biomass, and industrial sources poses significant concerns because of its continuous production and diverse chemical and physical characteristics. Proper handling and conversion strategies are required to address these issues. The chemical looping process connects organic solid waste to energy production. It is aimed at achieving sustainability through efficient and economically viable methods. This review highlights various sources of organic solid waste and their environmental impacts. It describes chemical looping conversion processes such as combustion, gasification, reforming, and pyrolysis, applied to organic solid waste. In addition, it presents an extensive overview of the applications of the chemical looping process in CO₂ capture and utilization and in bioenergy production. This review also delves into techno-economic analyses and feasibility considerations across chemical looping processes and applications. Furthermore, it discusses the challenges and prospects for promoting potential industrial applications and areas for further research on chemical looping processes.
