Abstract
The rise in the world’s population, combined with the expansion of agricultural practices and the processing of food, has resulted in an increase in the production of waste from agricultural practices, as well as challenges with its management. Converting agricultural waste (AW) and crop leftovers into useful forms can help alleviate some of the problems caused by the massive amount of waste produced by these activities. The conversion of this waste into biofuels continues to be an alternative that is both environmentally friendly and economically practicable. One of the most promising methods of turning biomass into biochar, biooil, and syngas is microwave-assisted pyrolysis (MAP). It is very important to carry out a technoeconomic analysis (TEA) and a life cycle assessment (LCA) before attempting to transform a lab-scale microwave reactor into a commercial plant. This will allow one to gain an understanding of the economic feasibility of the project as well as the environmental implications it will have. This chapter focuses on the concept of circular bioeconomy emphasising the technoeconomical aspects of MAP for bioenergy production from agricultural waste. It also discusses briefly the parameters and challenges involved in both batch and continuous MAP techniques. Further, this chapter examines the environmental performance of agricultural waste via life cycle assessment of biofuel generation with several MAP approaches. Various waste utilisation routes of life cycle assessment illustrate the potential of each residue in terms of impact categories such as global warming potential, eutrophication potential, acidification potential, etc.
