The world population is
increasing every year from the mid-2013 there are population around 7.2
billion and will reach to 8.1 billion in 2025, in the future will increase to
9.6 billion in 2025 and 10.9 in 2100. This assumes a decline of fertility for
countries where large families are still prevalent as well as a slight
increase of fertility in several countries with fewer than two children per
woman on average according to the increasing population in the world, the
amount of the household waste is also increase. Especially, the waste of
human from the toilet and household wastes. This is including human feces and
black-water. Because of that we have to collect and reuse for other purposes
such as biogas plant, and organic fertilizer.
The biogas plant is a commonly
used biofuel around the world and is generated through the process of
anaerobic digestion or the fermentation of biodegradable materials such as
biomass, manure, sewage, municipal waste, rubbish dumps, septic tanks, green
waste and energy crops. This type of biogas comprises primarily methane and
carbon dioxide. The actual composition of biogas will vary depending upon the
origin of the anaerobic digestion process which anaerobic digesters can be
fed with energy crops such as biodegradable wastes, including sewage sludge
and food waste. An air-tight tank transforms the biomass waste into methane
producing renewable energy which can then be used for heating, electricity,
and many other operations that use any variation of an internal combustion
engine.
In our
master plant we will make Biogas plant and organic fruit from household
wastes including human feces and solid waste. The first of step we will take
the waste from house and city to our land that quite far from city mash the wastes and mix well then send to the biogas system. When organic
waste from households and human feces is broken down by micro-organisms,
biogas is produced. For most efficient use this raw biogas is then upgraded
to maximize its energy content.
Biogas is a clean energy source. Bio-methane is
interchangeable with conventional natural gas thus can be injected into the
natural gas grid, used as vehicle fuel as either compressed re-newable
natural gas (RNG) or as liquid renewable natural gas.
For
fertilizer from biogas system we will take it to our organic orchard that’s
the tree wall for decrease bad smell from biogas plant and can harvest the
fruit as well, the tree that we choose is evergreen tree because, their leaf
will always block and decrease the wind flowing from our system to the city,
the evergreen tree including Mango tree and Mangosteen tree, those of fruit
are important export fruit from topical country.
In our
target for this master plan we need to decrease the amount of household waste
leading to the increment of spreading of water and food borne diseases,
decrease the greenhouse gas (GHGs) emission from human, deteriorating nature
environment and lead to the better quality of live and city.
