The space used for residential purposes is called residential. Commercial is a space that is used to make a profit, or to conduct activities other than the simple purpose of life. However, there are many subtle differences that people are not aware of, and it is used by the authorities to separate properties instead of stamp duty, electricity rates, or any other utility bill. The structure made for Residential and Commercial activity is used by people. For this Large piles of rubbish are created in residential and commercial area. The Industrial factories are very much needed for cleaning garbage and waste of factories.
Waste management
Waste management is a management
which refers to the integrated process of waste collection, transportation,
processing, recycling, and disposal. The process involves the work of
mitigating the harmful effects of those substances on the health of the
environment. Waste management is also used to prevent environmental damage from
waste and to collect recyclables from waste. It deals with liquid, solid or
gaseous garbage by different methods and skills. The type of waste management
varies in developed or developing countries, urban or rural areas, residential
or industrial areas. Usually local or municipal authorities manage for
non-toxic wastes from residential or institutional areas. On the other hand,
non-toxic wastes in commercial or industrial areas have to be managed by the
producers.
Structural and chemical properties of waste:
It is important to know its structural and chemical properties for waste management.
Structural features
To know about the structure of waste, one has to know the following characteristics: Partial Proportion Analysis. Waste-particle size analysis (Particle size). Moisture content of waste. Density of waste.
Partial
ratio analysis
In this analysis, it is possible to
identify all the different types of waste that have been mixed together and to
determine their (percentage) proportions. For such analysis, samples of freshly
dumped garbage are collected from the dustbin / dumping site and divided
according to the material, and the weight and volume of each portion are
measured. Below are some of the data from such an analysis:
Waste-particle size analysis:
If recyclable waste is separated from
the waste by mechanical means or with the help of a sieve / sieve or an
electric magnet, then it is necessary to have an idea about the size of the
waste particles. In general, per unit weight of dirt contains more small
particles than large particles.
The aqueous part of the waste
In order to extract the aqueous part,
the waste parts separated in partial analysis are dried in the oven and weighed
again. Then, the lost weight is expressed as a percentage of the first weight.
That is % Aqueous portion = 100 × (initial weight - weight after drying) /
initial weight .This is the technique of
determining the aqueous part of a particular part / material. Although the
proportions of the waste components in different areas are different, the total
aqueous portion can be extracted from each previously calculated type /
component data without testing. Therefore, from the aqueous part of each
material, the weight of the material is determined. Then the dry-weight of the
whole dirt is divided by the total weight. See an example -
1000 kg of waste has been partially analyzed:

Total dry weight = |
690 kg. |
Thus, % of total waste water content = 100 × (1000 – 790) /
1000 = 21%
Increasing the efficiency of waste disposal:
To increase the efficiency of waste
disposal, it is important to have an account of the water content. If the dirt
is burned, it is possible to calculate how long it will take for the dirt to
dry before setting it on fire, and to determine the optimum rate of littering
in the furnace. Besides, the heat value of that waste can also be estimated.
Even if compost-manure is made with some part of the dirt, it is possible to
calculate how much dry matter should be added or how much water should be added
to maintain the optimum water ratio for making compost. It is also easy to
estimate how much extract will come out of the wastewater if the waste is
dumped and the rate of running the pump to extract the extract from the bottom
of the wastewater can be determined in that proportion.
Waste density:
In addition to taking the weight of
the partially analyzed components to determine the density of the waste, their
volume is also measured. Then the density is obtained by dividing the weight by
the volume. From the density of each component it is possible to find out the
concentration of dirt mixed in any proportion as in the previous example.
Basically it is very important to
know the density of waste for waste transportation and disposal. Each garbage
truck has a specific bearing capacity. There are also size limitations for
cars. The waste management company can determine the amount of garbage
generated per day (in terms of weight) in an area and the number of trucks of a
certain size and capacity to collect the garbage if it is known from the
partial analysis of the garbage.
Chemical properties:
In order to extract energy from waste in an alternative way, it is important to know its chemical properties very well. The chemical analyzes performed for this purpose are summarized as follows:
Proximity analysis:
Aqueous part
- How much water part is lost if kept at 105 degree Celsius for 1 hour.
Volatile
matter - The excess that is lost when heated to a temperature of 905
degree Celsius
Ash - The
amount of residue after burning.
Stuck carbon
- the rest.
Ultimate analysis
I. The percentage of carbon
II. The percentage of hydrogen
III. Percentage of oxygen
IV. Percentage of nitrogen
V. Percentage of sulfur
VI. The amount of ash
Ash analysis
Determining the melting temperature of ash
Determining the amount of heat energy
I. The amount of energy produced by burning each element of a certain weight is measured / determined.
II. Energy is measured in 3 states: They are
III. What will happen if the garbage is burnt in the same way?
IV. What will happen if it is burnt in dry condition
V. What will happen if the ashes are burnt in dry condition?
VI. More about waste
Conclusion:
Finally we can say the Industrial
factories are very much needed for cleaning garbage and waste of factories.
People cannot live in peace without cleaning the environment. Various kinds of
disease spread to us for environment pollution. So really we should research
more about the residential and commercial cleaning
industry.
