INTRODUCTION
• Solid waste is the unwanted or useless solid materials generated from
combined residential, industrial and commercial activities in a given
area.
• It may be categorized according to its origin (domestic, industrial,
commercial, construction or institutional) according to its contents
(organic material, glass, metal, plastic paper etc).
• Management of solid waste reduces or eliminates adverse impacts on
the environment and human health and supports economic
development and improved quality of life.
• These include monitoring, collection, transport, processing, recycling
and disposal.

PROBLEM STATEMENT
• Most landfills lack proper on-site waste management thereby
contributing to additional threats to the environment.
• In the long-term, landfills leak and pollute ground water and other
neighbouring environmental habitats making waste management very
difficult.
• They also give off potentially unsafe gases to overcome this problem
we came across this solution.

Objectives
• To study the waste management of our city.
• To design and fabricate the model.
• To decease quantity of municipal solid waste to 80- 90%.
• To reduce landfill in cities and hence reduce methane gas
emission occurring due to it.

WORKING PRINCIPLE
• Firstly the solid waste is collected of less moisture content is fed to
the Incinerator.
• The temperature is maintained at around 350⁰C using the thermostat.
• The waste is incinerated using the heating coil and the burnt gas is
sent to send chamber which is condenser.
• In condenser the heat exchange take place between the cold water and
copper tubes.
• The water can be heated by the copper tube, this heated water will be
used for various purposes.
• The flue gases is sent to atmosphere by means of flue gas outlet.

Material selection
 We selected Mild steel as our material for our fabrication Strength
Mild steel is very strong due to the low amount of carbon it
contains.
 In materials science, strength is a complicated term.
 Mild steel has a high resistance to breakage.
 Mild steel, as opposed to higher carbon steels, is quite malleable,
even when cold.
 This means it has high tensile and impact strength.
 Higher carbon steels usually shatter or crack under stress, while
mild steel bends or deforms.

Results And Discussion
Our model can accommodate 5-7 Kg of solid waste per use.
Temperature of Incinerator is set around 200- 300℃ using a thermostat.
When the temperature reaches around the optimum value the
temperature cut-off takes place.
Trial 1
• We took agriculture solid waste which comprises of rotten tomatoes,
cabbages, spinaches etc, All of 1kg weight. As we maintain
temperature of 200℃- 300℃ all our waste gets burned in 49 minutes
and pressure of incinerator is around 5 Psi and giving ash, good
amount of methane and hot water from condenser as output.
• As the gas coming from outlet of condenser is further processed by
treating it with water and send it to atmosphere, hence reducing air
pollution.

Trial 2
• In our trail 2 waste comprises of mixture of solid waste including mix
of agriculture waste, plastics, paper. We took around 1 kg of mix
waste to conduct the test around 250℃-300℃ and pressure developed
was around 5-6 Psi.
• All the waste got burned around 1hour 25minutes, we could note that
amount of methane gas was less compared to trail 1 and soot
formation was there and while treating with water before sending it to
atmosphere water turning to slightly dark brown colour.
• And condenser water to got hot after the heat exchange between the
water and copper tubes and hot water temperature is slightly greater
than the trail 1.

Advantages
• Incineration plants can be located close to the dump yard, thus
reducing the cost of waste transportation
• Using the ash from MSW incinerators for environmentally appropriate
construction not only provides a low cost aggregate but further reduces
the need for landfill capacity.
• Energy can be recovered for heat or power consumption.
• Incineration provides the best way to eliminate methane gas emissions
from waste management processes.
• Air pollution control remains a major problem can solved using this.

Conclusion
• The average calculation of the per-capita solid waste generation per-
day in city shows that it is in no way less compared to the other major
cities of India.
• The solid waste generation of the city increases with urbanization is
obvious from the study as it is noted that city contributes less waste to
the main Municipal Solid Waste generation.
• It is evident and true that all want to get rid of their waste. But the
survey shows that getting rid of waste and its management in a
scientific and effective way is more often lacking.
• Public awareness, effective community participation, transparent and
clean administration, and accountability in the least levels can only
bridge this gap.

SCOPE OF FUTURE WORK
• The market of energy waste is growing rapidly throughout the world.
Which is using waste as fuel and makes it hard to recycle, in the
process of recycling which gives harmful by-products and toxic gases.
• This technology helps us to recover products for waste and incinerate
completely and does not focuses on biomass waste. Gasification uses
a large range of raw materials which involves less oxygen and
produces synthetic gases which can be used to power the steam
turbine to produce the electricity.
• The land fill gases and methane have high global warming potential
which is 23 times greater than that of carbon dioxide. Use of better air
quality has to be tested before sending to the atmosphere by applying
air pollution unit and has to release cleaner and safer air which is free
from toxic substance and has to be safe for human health.
