By 2020, the biomass energy development and utilization of capacity of 500 million tons of standard coal, equivalent to more than 15% supplies. And extremely low sulphur content of the biomass %, 1/4 not to the sulphur content of the coal. Development of biomass solid fuels, implement coal alternatives, significantly reduces the carbon dioxide and sulfur dioxide emissions, have a significant environmental benefit.
