The aim of this paper is to present a comprehensive review on renewable methane fuel production
through the biological route of biomethanation process from major lignocellulosic agricultural crop waste
biomass (maize, wheat, rice and sugarcane). Global annual approximate production of major agriculture
based lignocellulosic biomass has been explored. Fundamental requirements of biomethanation
process have been discussed in details for optimum production of methane. The essential properties
of biomass (proximate, ultimate and compositional) conscientious for quality of derived fuel have also
been presented along with the pretreatment requirements for lignocellulosic biomass. Methane generation
potential of the major lignocellulosic agricultural crop biomass has been explored and presented.
Furthermore, the methane production potential and its energetic analysis have also been compared with
the bio-ethanol productions. The overall parametric analysis involved in anaerobic digestion and alcoholic
fermentation explore that methane generation from lignocellulosic agricultural crop waste biomass
is more economical and environmentally beneficial way of biomass utilization in a sustainable way of
energy production.
