This book covers sustainable recycling processes (e.g. physical, biological, chemical, and thermo-chemical) of multiple organic solid wastes, provides methods for material recycle of wastes into value-added products including fuels and commodity chemicals that are able to be directly applied to promote manufacturing processes. Aimed at improving the awareness of effective conversion protocols and for developing innovative biomass conversion processes, this text was conceived as a collection of studies on state-of-art techniques and know-how for production of biofuels and chemicals from sustainable recycling of organic solid wastes. Topics in the text are discussed in terms of addressing recent advances, assessing and highlighting promising new methods or new technological strategies and direct conversion of organic solid wastes to process feeds. Highly-recognized authorities, experts and professionals have contributed individual chapters in selected areas to cover the overall topic in a comprehensive manner.

Zhen Fang is a Professor and Leader of the Biomass Group at Nanjing Agricultural University. He is the inventor of the "fast hydrolysis" process, the elected fellow of the Canadian Academy of Engineering. Professor Fang specializes in thermal/biochemical conversion of biomass, nanocatalyst synthesis and their applications, pretreatment of biomass for biorefineries, and supercritical fluid processes.
