With regard to competition and economic conditions from pulp and paper plants, it is possible to provide emerging products and energy in wood and pulp industries, which may affect the main products and they will be converted into by-products. In future the world needs clean and renewable energy, which will be supplied, from biomass conclusively. In order to produce oxygen and carbon dioxide absorption, the tree plantation will be very useful on earth's atmosphere. Wood waste and biomass are rich of carbon and hydrogen, and they can provide energy and different chemicals by the new techniques. The principles are similar to refineries and petrochemical plants called biorefinery, and biofuels and valuable chemicals such as methanol, Fischer-Tropsch Liquid (FTL) and Dimethyl Ether (DME) are produced. Usage of any kind of biomass, agricultural waste, and wood can be useful to produce a variety of wood products, wood composites, and also paper and paperboard. But the first step, in proper planning of forest is the silviculture by natural resource specialists. Concerning production of wood and paper, gasification is the best method of chemicals and energy production from wood wastes and black liquor. In the last years, researchers have developed new fields of fuel and energy from renewable sources, specifically biomass dramatically.
