Thermochemical Valorization of Biomass: Pyrolysis and Gasification

Résumé fourni par la source

Biomass wastes generated from agricultural, municipal, industrial, and food-related activities represent both an environmental burden and a potential renewable resource within the circular economy framework. This chapter examines the thermochemical valorization of biomass, with particular emphasis on pyrolysis and gasification as two major conversion routes for waste-to-energy and value-added product generation. The chapter first outlines the relationship between biomass utilization, waste management, renewable energy demand, and circular economy principles. It then discusses the basic characteristics of thermochemical conversion processes, focusing on pyrolysis and gasification mechanisms, operational conditions, and the main process parameters affecting product yield and quality. Particular attention is given to biomass type, temperature, heating rate, residence time, pressure, pretreatment, catalysts, particle size, and reactor configuration. The chapter also summarizes the production and potential uses of the main thermochemical products, namely biochar, bio-oil, and syngas, in energy production, soil amendment, environmental remediation, chemical production, and other sustainability-oriented applications. Overall, the chapter highlights that pyrolysis and gasification can contribute to renewable energy generation, waste reduction, and resource efficiency when process conditions, feedstock properties, and product utilization pathways are properly optimized.
