Energy recovery from waste biomass through gasification

The production of sustainable and green energy is an important means to cope with global warming and promote the sustainable development of human society. Biomass is a significant renewable energy source to satisfy daily energy needs because of its diversity, abundance, and availability. Gasification is a multifunctional and environmentally friendly technology that can produce a range of products such as syngas, heat, electricity, biofuels, and chemicals from waste biomass. This chapter provides an overview of the current status of gasification technology, including reaction mechanisms, various gasifiers, gasification processes, biomass properties, operating parameters, and end products. The chapter also highlights recent advances in biomass gasification commercialization, introduces the economic and environmental performance from the large-scale implementation of waste biomass gasification, and proposes strategies for further improvement. Most importantly, the chapter discusses the challenges and opportunities for further research and development in gasification technology. This chapter summarizes the present situation, problems, potentials, and prospects of gasification technology and its application in a series of fields, providing valuable insights for researchers, practitioners, and decision-makers in this field.
