1. Group biomass

2. Interduction biomass
•
•
Biomass is plant-based material used as fuel to
produce heat or electricity.
Biomass continues to be an important fuel in
many countries, especially for cooking and
heating in developing countries. The use of
biomass fuels for transportation and for
electricity generation is increasing in many
developed countries as a means of avoiding
carbon dioxide emissions from fossil fuel use.

3. Cont....
• Biomass contains stored chemical energy from
the sun. Plants produce biomass through
photosynthesis. Biomass can be burned
directly for heat or converted to renewable
liquid and gaseous fuels through various
processes.

5. Converting biomass to energy
•
•
•
•
•
Biomass is converted to energy through various
processes, including:
Direct combustion (burning) to produce heat
Thermochemical conversion to produce solid,
gaseous, and liquid fuels
Chemical conversion to produce liquid fuels
Biological conversion to produce liquid and
gaseous fuels

10. Wood Westes
• The primary constituents of wood waste are
used lumber, trim, shipping pallets, trees,
branches, and other wood debris from
construction and demolition. The Construction
and Demolition Debris Recycling Urban Wood
Waste page suggests various ways to reuse
this valuable resource.

11. Advantages of biomass
•
•
•
•
•
Biomass is always and widely available as
a renewable source of energy.
Biomass is clear source energy
It's good for mother nature and business
Biomass are renewable source
Less dependency on fossil fouls

12. Disadvantages of biomass
•
•
•
•
•
It requires water
Can be become non_renewable energy
biomass plants require alot of space
Economically not so effecent
Low energy density

13. Question
• Where is biomass energy used?

14. Answer
• Biomass continues to be an essential fuel in
many countries, especially for cooking and
heating in developing countries. Also,
consumption of biomass fuels for
transportation and electricity generation is
increasing in many developed countries to
avoid carbon dioxide emissions from fossil
fuel use.
