Volume 2, Issue 5
Feature: Biofuel from fishwaste |
Several headlinegrabbing
reports in
the last few months
have highlighted that
commodities such as corn,
rapeseed, palm oil and soya
are often being grown and
harvested in a way that could
have negative economic, social
and environmental effects.
Countries like Haiti,
Bangladesh and Egypt have
already seen riots as a result
of soaring food prices.
One way to alleviate the
pressure of biofuels and in
part give the land back to food
production, is to look at more
sustainable alternatives which
do not use up agricultural land.
Using fish waste to
produce biodiesel is a very
viable alternative. The use
of animal waste and oil to
produce biodiesel is not a new
technology, but the adaptability
of this technology to aquatic
resources has only recently
attracted public interest.
The process is relatively
simple. The production of
biodiesel starts with crushing
the fish waste. This allows
the oil to be extracted, which
is mixed with methanol
(roughly 9%) and caustic
soda (in order to separate the
glycerine from the biodiesel).
The fuel is then purified by
adding manganese (a naturally
occurring element in nature)
and is then fit for engines. The
by-product, glycerine, is sold
to the cosmetic industry for
the production of soap and the
residues are made into fishmeal.
There are two main
companies which are making
significant contributions to local
energy production through
the use of fish residue/waste:
Aquafinca in Honduras,
Central America, which uses
tilapia, and Agifish in Vietnam,
which uses catfish waste.
