History of Biomass

• Biomass fuel has been used for energy for years.
  Henry Ford powered his first Model T using
  biomass energy.

3
How biomass is obtained

• Biomass is a renewable resource that comes from
  plant matter. During the process of
  photosynthesis, the building blocks of biomass
  are formed by carbohydrates.

• This occurs when carbon dioxide from the
  atmosphere is combined with water from the earth.

4
Refining Biomass

• Techniques to transform biomass into fuel using
  Bioconversion and Thermal Conversion are
  currently under development at different research
  laboratories.

Composition of Biomass

How is Biomass used?

• After being changed to
• fuel from plants,
• Biomass can be
• used by burning the
• fuel to give of energy.
• It is like a very safe,
• efficient form of gasoline.

7
Positive aspects of biomass

• Biomass can solve nearly all of the worlds
  energy problems.
• Biomass is safer than most sources of energy on
  the environment.

8
Negative aspects of biomass

• The burning of biomass sends carbon dioxide
  into the air, which contributes to the Greenhouse
  effect. However, if a new tree was planted for
  each tree that was used for the making of
  biomass, the new tree would take all of the
  carbon dioxide out of the air that the burning of
  the old tree put into the air. Therefore, there
  would be no long-term increase in carbon dioxide.

Hemp

• Hemp produces more biomass than any plant that
  can be grown in the United States. Many
  scientists believe that if hemp were made legal
  and widely grown in the U.S. for biomass, it
  alone could supply 100 of U.S. energy needs.

• Actor Woody Harrelson, who has become a major
  environmentalist, recently toured the country in
  a bus that was converted from diesel to hemp
  biomass fuel.

Woody explains the benefits of hemp biomass fuel
at the Seattle Hemp Festival.
