The extensive use of fossil fuels has created a global problem of pollution and other environmental menace. Nevertheless, there is huge increase in the awareness and global involvement in the environmental conservation and sustainable ecosystem. This impetus in the natural conservation inspired to think for the alternative and renewable resources to meet the energy demand of the increasing population. The concept of bioenergy is one of the very important part and pivotal factor of the recent trends in the alternative energy regime. In this review, a brief introduction of the bioenergy and biomass processing is presented with the overall reconsideration and future overview of the bioenergy and society.

Excerpt from the Book
Processing Biomass
For the maximum gain of the energy from the biomass, the bio-based materials are treated using different methods and techniques. This process makes the energy transformation easier and efficient. For a sense of understanding, the biofuels can be classified as solid (wood chips, pellets, charcoal), liquid (biodiesel, bioethanol) and gaseous (biogas, syngas, hydrogen) biofuels (Bauen et al 2009; Kwant & Buckley 2015).
Different conversion technologies have been developed for the processing of biomass based on the physical and chemical properties on the biological material. The conversion technologies might be based on the thermochemical processes (chemical degradation at high temperature), physicochemical processes (mechanical application and biochemical processing) or biological conversions (fermentation) et cetera (Bauen et al 2009). On the basis of the physical state, the resulting biofuels can be classified into three classes i.e. solid biofuels, liquid biofuels and gaseous biofuels.
