One 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.
The advantages of using biogas first is
absolutely reduce our household waste. Teodorita Al Seadi who is biogas experts
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 this 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. When we used biogas stoves, not take a long time to heatup, so as
soon as we have turned on the stove, we can start cooking.
Based on Homebiogas official website, biogas
can also produce our own organic fertilizer. The dregs of biogas from the
systems rich in nutrient and it can be applied to help plants grow. The dregs
also replaces 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.
As 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. In this study, the major victims were woman, children, and old
people that access to kitchen activities at the time of food preparation. By
using the smokeless biogas, we contributing to a reduction in eye related
problems and respiratory diseases.
Biogas 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 used 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.
