of labour, may be listed as some of the benefits of its use.Also, in relation to other forms of renewable energy, biomass, as chemical, energy has a prominent position due to high energy density and storage facilities, Exchange and transport. The similarity between the engines and systems of energy production of biomass and fossil fuels is another advantage, thus not have an effect as wall-to-wall nor industry production equipment or bases imposed on transport and manufacturing electrical energy.MaterialsWood is used for production of biomass energy. In Brazil, already represented 40% of primary energy production. The major disadvantage is the deforestation of forests;Marc cane sugar;Powder Sierra;Paper already used;Twigs and leaves arising from the pruning of trees in cities or houses;Packaging cardboard discarded after the acquisition of various appliances or other products.Paddy rice.Elephant [1]Products derived from biomassSome examples of products derived from biomass are:Bio - oil: black obtained through the pyrolysis process whose main how are heating and electrical power generation.Biogas: methane retrieved together with carbon dioxide through the decomposition of materials such as waste, food, sewage and liquid manure in carcase disposal plant biomass.Biomass - to - must have: NET in two stages. First is a process of gasificacao, whose product is process Fischer - Tropsch process. Can be employed in the composition of liquid fuels and lubricants for use in diesel engines cycle.Cellulosic ethanol: ethanol raised by two processes. On one of them biomass, consisting basically by molecules of celulose, is submitted to the process of hydrolysis enzyme using various enzymes, such as cellulase, celobiase and - glicosidase. The other process is composed of the implementation of the following three successive stages: gasificacao, fermentation and distillation.Bioethanol "common": made in Brazil based juice extracted from the sugarcane (garapa - shives). There are countries which employ maize (United States) and beet (France) for their production. The system - based cane sugar employed in Brazil is more viable than the one used by American and French.Biodiesel is made of palm oil, castor tree and soya.Vegetable oil: can be used in diesel technology ElsbettJoint ventures in BrazilIn Brazil there are some initiatives in this sector, particularly in the section of transport. The USGA, diethyl oil, castor tree and some compounds alcohol as the azulina and motorina were produced to replace gasoline successfully 1920s until the early days of the following period of ten; collapse arising from the first world war.The mixture of alcohol in petrol, started by law in 1931, enabled Brazil the improvement of the outcome of combustion engines so guaranteed and higienica; the use of additives veneniferos as lead tetra ethyl, that similarly have been used in other countries upward characteristics anti-knock petrol has been avoided. Is of great importance, enabling the use of higher compression engines the explosion.The Pro alcohol ordinary years 1970 consolidated option alcohol as an alternative to petrol. Despite the problems faced as values fall in international oil and fluctuations in the price of alcohol, which affected often offer internal alcohol, the effects of governmental strategy survive on their increments. Gasoline is a mixture containing 25% of alcohol and the
