Traditional biomasses are major
fuel source for millions of people dwelling in developing countries. Use of
wood dominates the biomass but they are depleting in major quantity because of
excessive population. Coal, charcoal, sawdust, agricultural wastes are some
other biomass used by people among them charcoal is widely used as a domestic
fuel which is made in absence of oxygen by draining out all the water from
wood.
Charcoals are light black
residues remnants of wood which is highly carbon induced. Utilizing this energy
would not be the best option for environment but they are sustainable in
comparison to wood. Wood are the first products which are used directly used by
burning them whereas charcoal is formed by burning the wood. Charcoals had been
produced for ages and still are abundantly used in developing world. Using
brick or traditional kilns, farmers lived in dense forest to produce them.
Still in countries like Sudan and
Kenya, farmers and peasants make charcoal using traditional techniques.
Charcoals utilization reduces smoke to much less in context with wood burning.
Choosing correct type of kiln for charcoal production is necessary and it
determines the quality of charcoals. Through the guides and information
provided by Practical Answers, people can use the charcoal production technique
to make chars from different forest residues.
Sugar cane Bagasse, Sawdust
Coconut and coffee husk, Wattle bark, Macadamia nut shell also have potential
for charcoal production. Helping through its technical information, Practical
Answers provides its informative guide online. The guides were used by people
of Kenya and Sudan to access all the information on charcoal production from
selecting the best type of kilns for quality charcoal production to the effects
of charcoals on environment. Like every other energy source, charcoals also
have its disadvantages but it has more merits in comparison to wood.
Utilization of charcoal is mostly
done for cooking purpose in developing regions but it also is used for art,
medicine, purification and filtration and horticulture. Charcoal production is
mostly illegal now in many countries but they are a better fuel source for
people living in poor regions than wood. Utilizing agricultural waste people
could make charcoals for better energy access.
