Biomass energy used in methods such as direct combustion, methane fermentation and gasification by pyrolysis has been reviewed as a promising source of energy. By 2010, the European Union has doubled its share of renewable energy (including geothermal and large-scale hydropower) from 6% to 12% in total energy, up 8. It plans to make biomass for 5% (10 million kw in heat output). Sweden and Finland that have been working relatively early have already covered about 20% of the primary energy supply and 12% Austria. The use of biomass in the European Union is mainly due to the local heat supply through combustion. In Sweden, many municipalities have heat supply facilities that burn wood and other trees that cannot be used for timber, and heat is being sent to public facilities and houses through piping that is built underground in urban areas. <!--more-->
In areas that do not draw piping, woody fuel processed small pellets are used for the fuel of stoves and small boilers. Because plant resources are used to fix CO2 by photosynthesis, the total amount of CO2 in the atmosphere can be kept constant if the tree is planted even if it burns it. In food factories and paper mills that generate a large amount of organic wastes, it is possible to recycle in the factory and reduce the cost of energy, let alone the processing cost. Especially for food waste recycling law in April 2001, more and more examples of adopting methane fermentation technology are being used in food factories.
