The document discusses integrated green technologies for municipal solid waste (MSW) management. It describes an automated waste collection system and various MSW thermo-chemical conversion technologies, including recycling, combustion, incineration, pyrolysis, gasification, and advanced thermal gasification. Incineration can generate energy from MSW but requires effective pollution controls. Emerging technologies like gasification and pyrolysis produce syngas and oils while advanced thermal gasification vitrifies waste into inert materials. Overall, thermal conversion technologies allow for more sustainable MSW management compared to landfilling but require further commercialization and environmental assessment.
Plasma pyrolysis Technology for waste management (covid waste,hospital waste,...SABARINATH C D
Plasma pyrolysis is in the forefront of modern waste treatment. There is great potential for
development of thermal plasma pyrolysis technologies applicable to waste management with
energy and material recovery. Although important research progress in this area has been
made in recent years, there are still considerable technical challenges to be faced in
developing and modifying thermal plasma pyrolysis processes for industrial applications.
Plasma pyrolysis process fulfils all the technical requirements to treat hazardous waste safely.
It is easy to maintain the arc in an oxygen-free environment, or one can vary the gas to alter
the chemistry of the process. The plasma pyrolysis system can have instant start and shut
down. It is possible to add features like interlocks and automation that make the system user
friendly. The plasma pyrolysis technology overcomes almost all the drawbacks of the
existing waste-disposal technologies. It provides a complete solution for the safe disposal of
medical waste. In addition, organic mass to gas conversion is more than 99% and it does not
require segregation of chlorinated hydrocarbons. The gases obtained after the pyrolysis are
rich in energy content and can be used to recover energy.

As rapidly increasing demand for electricity day by day Refuse Derived Fuel acts as an alternative source for the production of energy. As well as it also help to reduse landfill area where the municipal solid waste is dumped. Only the non-recycleable material goes to the landfill. Refuse derived fuel can also be used as the secondary fuel for the thermal power plant when with with the pulverized coal.

Soil is a peculiar material. Some waste materials such Fly Ash, rice husk ash, pond ash may use to
make the soil to be stable. Addition of such materials will increase the physical as well as chemical properties of
the soil. Some expecting properties to be improved are CBR value, shear strength, liquidity index, plasticity
index, unconfined compressive strength and bearing capacity etc. The objective of this study was to evaluate the
effect of Fly Ash derived from combustion of sub-bituminous coal at electric power plants in stabilization of soft
fine-grained red soils. California bearing ratio (CBR) and other strength property tests were conducted on soil.
The soil is in range of plasticity, with plasticity indices ranging between 25 and 30. Tests were conducted on
soils and soil–Fly Ash mixtures prepared at optimum water content of 9% .Addition of Fly Ash resulted in
appreciable increases in the CBR of the soil. For water contents 9% wet of optimum, CBRs of the soils are
found in varying percentage such that 3,5,6and 9.We will found optimum CBR value of the soil is 6%.Increment
of CBR value is used to reduce the thickness of the pavement. And increasing the bearing capacity of soil.

Conclusions
5. Most the generated MSW are disposed in landfill which is kind of
wasting a recyclables resources and losses of its energy content,
in addition of the adverse impact of this practices on the
environment as a result of ground water pollution and gaseous
emissions which cause the global warming problem.
Possible Waste Management Options :
Waste Minimization
Material Recycling
Waste Processing (Resource Recovery)
Waste Transformation
Sanitary Land filling.
Processing / Treatment should be :
Technically sound
Financially viable
Eco-friendly / Environmental friendly
Easy to operate & maintain by local
community
Long term sustainability
The main component of landfill gas are
methane and carbon dioxide. Both
components contribute significantly to
the greenhouse effect and are chiefly
responsible for global temperature rise.
RECOMMENDED APPROACHES TO WASTE
MANAGEMENT
18. Waste disposal technology improves over time as a result of :-
Higher awareness of environmental, safety and health impacts
More stringent requirement for compliance with emission
standards
Land scarcity
Drawing the most efficient recovery of energy from wastes
Not least, escalating fuel prices which makes fossil fuel more
expensive for power generation
Competitive cost of technology over time
Progress of Technology for Waste Destruction
(Non-recyclable MSW)
1 ton of solid waste generate 200 – 300 m3 of landfill gas
1 m3 of landfill gas contains 0.5 m3 of natural gas which
could be used as a fuel to generate 5 kWh energy.
1 ton of CH4 after combustion will generate 24 ton of CO2

Products are pyrolitic oils and gas, solid char
Distribution of products depends on temperature
Pyrolysis oil used for (after appropriate post-treatment):
liquid fuels,
chemicals,
adhesives, and other products.
A number of processes directly combust pyrolysis gases, oils, and char
30. Example: Fulcrum Bioenergy MSW to Ethanol Plant:
Construction on Fulcrum Bio-energy municipal solid waste to ethanol plant, Sierra Bio-
Fuels, started in 2008. Located in the Tahoe-Reno Industrial Center, in the City of
McCarran, Storey County, Nevada, the plant convert 90,000 tons of MSW into 10.5 million
gallons of ethanol per year.
34. Thermo-select (Gasification and Pyrolysis)
• Recovers a synthesis gas, utilizable glass-like minerals,
metals rich in iron and sulfur from municipal solid
waste, commercial waste, industrial waste and
hazardous waste
• High temperature gasification of the organic waste
constituents and direct fusion of the inorganic
components.
• Water, salt and zinc concentrate are produced as
usable raw materials during the process water
treatment.
• No ashes, slag or filter dusts
• 100,000 tpd plant in Japan operating since 1999

avoidance of use of fossil fuels for power
generation.
• Improved environmental data needed on
operating systems
• Comprehensive environmental or life cycle
assessments should be completed
