Abstract: A method for converting agricultural biomass or industrial bio waste into biofuel using concentrated radiated energy is disclosed. Biomass or bio waste is stored inside a batch reactor in either solid or semisolid state.

Due to substantial matching of the absorption peak of biomass or bio waste with the emission peak of the concentrated radiated energy, the biomass or bio waste that is within the depth of focus instantaneously decomposes into biofuel. The biofuel thus generated is at ambient temperature with higher energy density.
