Biomass is based on carbon. It is also the admixture of organic 5Tmolecules that include hydrogen; 5Toxygen; often nitrogen and small amounts of other atoms like alkali metals; alkaline earth metals and heavy metals. Better method of producing biomass for more energy production has the potential to replace fossil fuels. Converting biomass to liquid; gaseous or solid fuel depends on four main characteristics:

1) Platforms 2) processes 3) feedstock 4) products

Platforms are the most important feature in this classification; they are the key intermediate between raw materials and final products.

There are two main methods to convert biomass to liquid; gaseous or solid fuel: Biochemical and thermo chemical. Biochemical method is known as the sugar platform that is based on enzymatic hydrolysis and fermentation. Thermo chemical method depends on thermo chemical process. Methods that are in this category contain Direct Combustion Gasification and Pyrolysis.

Utilizing biofuels instead of fossil fuels due to a lot of reasons are preferred. They produce less COR2R than fossils; they produce a little bit of brimstone and they do not produce pure C. Moreover; they can help to reduce greenhouse gasses and can save the environment from destruction. On the other hand; using such fuels help not only the nature to be more stable; but also to gain stable increment in future.

This article is seriously focused bio fuels production process and the net effect of biomass energy production on the environment; tools and combining methods to produce components that cover the mechanism of biomass energy production process and the unique performance of these parts. In this paper the development of biorefinery technologies and using renewable resources in national and international level is studied. Of course it would be considered that producing more biomass for energy has the potential to pollute water resources and decrease food security.
