In the near future, fossil fuels would be to expire and scientists’ prospect has been attracting to produce bio-energy and biomass resources management. Solid Biofuels Technology from the perspective of economic and environmental policies has been a wonderful influence, although high costs and challenges dependent is relatively. The aim of this review article is investigation solid biofuels technology in order to convert all woody forest’s residues to wood pellets and other similar products. We present new hypotheses, approaches, Scientifics’ standards and applied methods in the production of solid biofuels, however this knowledge is traversing from the first steps. Consequently it is imperative to broaden its basic infrastructures and expand an effective associated knowledge.
