2. 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.
3. 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.

4. How can we transform biomass into other
chemical 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.
5. 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.
