THE CHARCOAL PELLET PRESS
How to Make Waste Charcoal Dust into Pellets
Using a Simple and Inexpensive Hand-
powered Press
Joyce Lockard
About half of the world’s people eat food cooked with wood and charcoal. Cutting trees for fuel is one reason that the world’s forests
are decreasing by about 2% each year.
Many women in developing countries have to walk long distances to find wood
At the same time, charcoal waste that is widely available is not being burned because no one
can cook a meal on a three-stone or other simple stove using charcoal dust for fuel.
The charcoal made in country-side kilns in developing countries is fragile. It readily
crumbles when it is broken into pieces for transporting and sale.
UP TO 40% OF CHARCOAL MAY BE LOST AS
DUST AND CRUMBS BEFORE IT GETS TO THE COOKING FIRE!
Large quantities of charcoal waste accumulate on the ground around
country-side kilns and market stalls.
But there is a way to make charcoal dust and fragments
into cooking fuel!
Charcoal dust that is too small to burn in simple stoves can be made into solid pellets with an
inexpensive CHARCOAL PELLET PRESS.
Cut a piece of plastic water pipe about 5-7 cm (2”-
3”) in diameter and 10-15 cm (4”-6”) long. Make a wooden plunger
that will fit loosely into the
pipe.
How To Make the Press
If you can’t get a plunger made with a lathe, you can use a machete to shape a plunger from
a tree branch.
You can paint the end of the plunger to help people not burn it for firewood by mistake.
Collect waste charcoal from around charcoal kilns and market stalls.
Sieve out the large particles and crush them.
Boil up grated cassava or another starchy plant material or use clay or termite mound
dirt to make a sticky paste.
Mix charcoal dust with enough paste so that it will stick together when you
squeeze a handful and hold it by one end.
Fill the mold about half full of mix.
Pound down the mix to make a solid pellet about 5-8 cm (2-3”) thick. Pounding by hand is all the
pressure that is needed to make a pellet.
Push the pellet out of the bottom end of the mold and put it in the sun to dry.
This is an appropriate
technology that reduces the need to cut down trees for firewood and
charcoal by utilizing waste
materials.
Using the pellet press, women can make their own cooking fuel.
And they can make additional pellets to sell for income.
