excellent source of energy is biogas. This is produced when bacteria decompose
organic material such as garbage and sewage in the absence of oxygen. Based on
Peter Jacob Jorgensen research, biogas is a combustible gas derived from
decomposing biological waste under anaerobic conditions. Biogas normally
consists of methane and carbon dioxide. This methane is also created in the
rumen of ruminant animals such as cows, sheep, camels, and deer. Farms that produce
a lot of manure like dairy farms can use biogas generators to produce methane.
Biogas energy offers many advantages and this is what will be discussed.
One of the
advantage of using biogas is absolutely to reduce
our household waste. Teodorita Al Seadi,
who is biogas expert from Denmark,
says that biogas systems convert organic household waste or manure into gas for
cooking and lighting. We can say that biogas is turning wastes into watts and
turning grass into gas because biogas can turn on electricity with our
household waste and can be produced from the organic materials into gas. This
waste can be leftovers, vegetables, peels of fruit and many more. Instead of
throwing them away or leaving them which will attract insects and pests, we can
use it to produce energy. Biogas can also improve our home because biogas is a
modern source of energy for cooking and lighting. It is quick, easy and clean.
on Homebiogas official website, biogas can also produce our own organic
fertilizer. The dregs of biogas from the systems are rich in nutrient and it can be
applied to help plants grow. The dregs also replace chemical fertilizers. This
saves money and is better for environment. Talking about environment, using
biogas is saving fossil fuel too. There is no additional carbon dioxide that
produced by the biological process when burning it. But there is a significant
difference. The CO2 emission that originates from the use of biogas
matches same amount that plants need to grow and produce renewable resources.
On average, each family that uses biogas reduces their use firewood and
charcoal by more than 60%. The use of biogas slows down deforestation and
reduces greenhouse gas emissions. Biogas has a positive influence on the
environment. And of course does not contribute to climate change.
we may know, cooking on a gas stove, instead of over an open fire, prevents the
family from being exposed to smoke in the kitchen. But sadly, 4.3 million
people a year die from illness because of air pollution that produced by the
use of solid fuels for cooking. Bajgain and Shakya (2005) stated that the
particles from the smoke can give respiratory infections and eye ailments for
the people who are in contact with smoke frequently. By using the smokeless biogas,
we contribute to a reduction in eye related problems and respiratory diseases.
is a reliable fuel, which is produced out of renewable resources, other
industrial side products or even waste. Unlike non renewable energy sources,
such as oil, coal and natural gas, renewable energy sources are considered
“sustainable” as they will not run out. In addition to this, renewable energy
sources have a less damaging effect on the environment. In the future, when the
non-renewable energy sources run out, whether you want it or not, we have to
use the renewable energy such as biogas. So, from now on, biogas should be
developed into a fuel that is suitable to use for all kinds of purposes.
