Introduction
Reliable energy supply is of paramount importance to
any country because it improves welfare and enhances the standard of living in
almost every aspect.
While the world is still looking for energy supply
alternatives which are cheap cost effective, affordable and environmentally
friendly, TEMDO has come up with the use of waste (used) lubrication oil as a
fuel or source of energy for domestic and commercial use both in urban and rural
areas.
After running for about 2000 km each motor vehicle
has to replace its engine lubrication oil. The waste oil after being discarded
normally finds its way to roads, rivers and on the land and becomes a pollutant
to the environment.
Use of the waste lub-oil as a fuel to substitute
fuelwood assists in conserving the environment and reduces pollution to some
extent. It is through this outlook
that TEMDO designed waste oil and multi-purpose
stoves that use waste lub-oil as fuel to reduce the adverse impacts of
deforestation for biodiversity and environmental conservation.

How to use the
multi-purpose stove.
§
Fill the
tanks with waste oil and water respectively
§
Open
fully the air regulator door
§
Place a
small amount of ash with kerosene under the ignition plate.
§
Light the
ash with a match.
§
Wait for
about 5 minutes to allow the ignition plate to be hot.
§
Release a
thin stream of oil to fall on the ignition plate
§
The
resulting explosion changes to frying sound, which is a series of small
explosions.
§
Adjust
oil and water to obtain clean smoke. The recommended oil to water ratio is about
3:1
( c)
The pedal operated seed treater
Seed treatment is one of the most efficient and
environmentally friendly ways of crop protection. In many African countries
traditional seed treaters treat only a small portion of the seeds, and the rest
are planted without any protection.
Through UNIDO assistance TEMDO developed a pedal
operated seed-treating machine.
The reason for developing the machine was the need
particularly in Africa for a low-cost, small-intermediate size seed treater. The
developed seed treater combines efficient mixing with simple, rugged
construction.
The TEMDO seed treater is intended for treating
different types of seeds/grains very evenly with liquid, slurry or powder
chemicals.
The machine which weighs 73kgs has a capacity of 5
kgs of seed per batch and can be used to treat up to one tonne of seed per hour,
The TEMDO seed treater is selling at Tshs.
