Fuelwood Facts
The use of fuelwood is creating
a human and environmental crisis in developing countries.
- Half the world's 2 billion fuel wood
users face fuel shortages.
- 100 million already experience virtual
fuel wood famine. (FAO)
- In Africa, 40% of energy requirements
are met by fuelwood.
- Wood burning creates deforestation,
desertification and erosion.
- Many sub-Saharan countries have had
over three quarters of their forest cover depleted.

Briquetting: An Answer to Desertification, Health
Problems, Unemployment and Reforestation in Developing Communities
(1/2
day)
Presenter: Richard Stanley, The Legacy Foundation
Briquette
making exemplifies the potential of appropriate technology. It
saves trees and prevents problems like soil erosion and desertification
by providing an alternative to burning wood for heating and
cooking. It substitutes agricultural waste like hulls, husks, corn
stocks,
grass, leaves, food and animal garbage for a valuable resource.
It improves health by providing a cleaner burning fuel. This
is dramatically true in places like Tibet where yak dung is
almost constantly burned in small tents. And in these situations,
it
also improves agriculture by preserving the dung for pastures
and gardens instead of letting it all go up in smoke (and into
people's lungs and eyes). The briquettes are also designed
for holding, growing, and protecting seedlings. It tackles the
problem
on both ends by giving a better alternative to firewood (40%
more efficient, longer burning, and hotter) as well as helping
with reforestation. At the same time as creating the above
benefits, Briquetting engenders many microenterprise opportunities:
making
the presses from locally available materials, supplying materials
and making the briquettes, selling and delivering the briquettes.
We
can arrange for someone with 15 years experience to visit a
remote village or training center, analyze and recommend the best
ratio of agriculture waste, show people how to make the presses
as well as how to make the briquettes.
Fuelwood Facts: The Issues
The use of fuelwood
is creating a human and environmental crisis in developing countries.
• Half the world's 2 billion fuel wood users face fuel shortages.
• 100 million already experience virtual fuel wood famine. (FAO)
• In Africa, 40% of energy requirements are met by fuelwood.
• Wood burning creates deforestation, desertification and erosion.
• Many sub-Saharan countries have had over three quarters of their
forest cover depleted.
Briquette Bio-Fuel
Briquettes are a processed biomass fuel that
can be burned as an alternative to wood or charcoal for heat
energy. Often they are
used for cooking. This fuel source can offset the consumption
of trees and help to decrease resultant desertification.
Agricultural and/or paper wastes are pressed
under high pressure, into compact patties or pellets. Using waste
materials makes the
briquettes a renewable source of fuel. The briquette press is
a relatively simple device, often easily constructed from local
materials,
which makes it an appropriate technology for underdeveloped and
resource depleted communities or markets.
Job Creation or Community
Program
A briquette enterprise introduces
new jobs into a community and creates the possibility for many
others, through expansion and
distribution relationships. They can also be used in a cooperative
or school enterprise to provide inexpensive fuel for cooking
and heating, virtually eliminating recurrent fuel expenditures.
The
technology is an excellent candidate for work-study or cooperative
programs.
Use of Waste Materials, a Renewable Practice
If
not performed directly, collection of briquette fuel materials
can be maintained by local suppliers capable of gathering the
left over agricultural and paper wastes which are commonly
abundant in human habitats, whether rural or urban. Small
community scale
processing operations can make use of traditional technologies
such as mortar and pestle or expand materials processing
to more efficient methods, such as use of mechanical threshers.
High Pressure
Press Models
Commercial models of briquette presses are available.
However, the consideration should be made that systems built
outside of
a community are often not as easily replicated or repaired
without a trained individual with access to proper resources and
services.
Geographically appropriate presses can be easily modified from
existing models, as there are many press designs that differ
greatly. Some different models of briquette presses which have
already been
designed and are being used all around the world include wooden
compound levers, hydraulics pistons, car jack presses, and
solar or pedal powered versions.
Needs are Best met by Appropriate
Solutions
Briquettes
can be created from agricultural and paper wastes, making them
a renewable source of fuel with little
to no
recurring materials
costs. Briquette presses are inexpensive and easy to produce
compared to alternate technological investments. An enterprise
making use
of briquette production can be very profitable for small
businesses and communities consuming other bio-fuels, such
as charcoal
and fire wood, that are increasingly scarce and expensive
in many
regions of the world. Briquetting can also be done in your
back yard making
good use of your junk mail. For more information on briquetting
please see this Overview.
Richard
Stanley, The Legacy Foundation
Richard
Stanley has 33 years experience working in developing countries,
the last 15 focused on briquetting. As employee, consultant,
and contractor for the United Nations and several European
and North American organizations, he's worked on renewable energy,
small industry, transportation, water supply, and sanitation
projects in Tanzania, Kenya, Malawi, Botswana, Ghana, Mali,
Haiti,
Nicaragua, Sri Lanka, Papua New Guinea, and Peru. He is one
of the world's few experts in the briquetting process, and this
is a rare opportunity for a hands-on learning experience in
this
important and potentially transforming appropriate technology.
