What is Biomass?• Biomass is biological material from living, or recently living organisms. As an energy source, biomass can be used directly, or converted into other energy products such as biofuel.• Biomass can also be used to generate electricity with steam turbines or to produce heat.
Where we can find biomass materials? Biomass sources can be for example, forest residues (such as dead trees, branches and tree stumps), wood chips and even municipal solid waste. Biomass includes plant or animal matter that can be converted into fibers or other industrial chemicals, including biofuels. Industrial biomass can be grown from numerous types of plants, including hemp, corn, poplar, willow, sugarcane, and a variety of tree species. http://www.youtube.com/watch?v=EPS9mPNT5t8
How can we transform biomass into otherchemical form in order to obtain energy? There are three types: Termical Conversion: These are processes in which heat is the dominant mechanism to convert the biomass into another chemical form. Chemical Conversion: Some chemical processes convert biomass into other forms, such as to produce a fuel that is more conveniently used, or to exploit some property of the process itself.
Biochemical conversion As biomass is a natural material, many highly efficient biochemical processes have developed in nature to break down the molecules of which biomass is composed, and many of these biochemical conversion processes can be harnessed.
