Introduction
What is biomass??
The total mass of living matter within a
given unit of environmental area.
Plant material, vegetation or agricultural
waste used as a fuel or energy source.

Biomass Resouces
1.Wood and agricultural biomass(wood logs,
chips, sawdust, bark and other organic
material.
2. Solid waste, by burning garbage heat and
energy is produced.
3. Landfill gas, Methane gas is produced by the
bacterial decay of dead plants and animals.
4. Alcohol fuels, Wheat, corn and other crops can
be converted into a variety of liquid fuels
including ethanol and methanol.

Converting biomass energy
into a useable energy source
1.Direct incineration
2.Bacterial Decay. (methane gas produced
by the bacterial decay of dead plants or
animals.
3. Fermentation, Adding a yeast to biomass
produces an alcohol called ethanol.
4. Conversion, Biomass can be converted into
gas or liquid fuels by using chemicals or heat.

Uses of Biomass
•80% of biomass energy is produced for
residential use.
•79% of the biomass we use today comes from
burning wood and chips.
•Biomass is used to heat homes, Wood is
burned in open fires or wood pellet boilers and
stoves.
•18% of biomass is produced for industrial use.
•2% of biomass energy is produced for
transport.

Advantages of Biomass
The main Advantages of Biomass are:
1.Biomass is a renewable fuel source.
2.Biomass energy production results in
minimal environmental impact.
3.Employment generation in rural areas.
4.Alcohol fuels are efficient and clean
burning.
5.The availability of biomass fuels is
universal.

Disadvantages of Biomass
When combusted to produce energy it
contributes directly to global warming.
An expensive source to produce and
convert.
On a small scale there is a likely net loss
in energy; as energy must be put in to
grow the plant mass.

The future of Biomass
Infinite fossil fuel resources are depleting.
Our dependency on oil must be reduced.
Renewable forms of energy generation will be
requireded to serve the global energy
requirements.
Ireland has a goal of 16%use of renewable
energy by2020(3.9% in 2008)
Today it accounts for 10% of the worlds energy
consumption.

Conclusions
Today we have looked at the varies
different aspects of Biomass including:
The sources.
The conversion of biomass to useable
energy sources.
The uses of Biomass.
The advantages and disadvantages
The future of Biomass.

Recommendations
Biomass offers a renewable solution to the fast
approaching global energy crisis.
Biomass is more eco friendly on the
environment than most other energy
generation methods.
E.U.policy is setting onerous targets for
renewable energy generation and biomass can
be used to help meet these targets.
Biomass will create much needed employment
in this Irish recession economy.
