3. ABSTRACT:-ABSTRACT:-
• Hence there is a great need for improving technology in the use
of non-conventional sources of energy which could greatly
decrease the environmental needs and which would assure the
future needs at affordable rates.
• presenting an overview of waste to electrical energy technology
The basic concept and different features of WTEE is described.
• It includes the various processes to produce Refused Derived
Fuel (RDF), its characteristics and classifications.
• This shows the solution to disposal of municipal and agricultural
solid waste which is an increasing problem today and the
developments and goals are described.
4. • India producing 68.8 million
tons per year of Municipal
Solid Waste or 188,500 tons per
day.
• GOI has provided assistance of
2500 crores under 12 finance
commission for SWM .
Why :- ?Why :- ?
7. • The waste in composed, land filled, recycled form is
converted to some form of energy is called as Refused
derived fuel (RDF).
• Recovering the energy from municipal and
agricultural solid waste.
• And this energy for power production by two
methods Incineration and Biomethanisation..
• The following are the Processing steps for RDF :-
• DRYING
• DENSIFICATION
• PHYSICAL SEPARATION
• CHEMICAL MODIFICATION

10. The American society for testing
and materials (ASTM) has
developed seven category define
of RDF
• RDF-1 - Raw
• RDF-2 - Coarse
• RDF-3 - Fluff
• RDF-4 - Powder
• RDF-5 - Densified
• RDF-6 - Liquid
• RDF-7 - Gas
RDF-CLASSIFICATION:-RDF-CLASSIFICATION:-
11. • Ash Content - 2-10%
• Moisture Content - 8%
• Volatile Material - 75-80%
• Sulphur Content - Nil
• Calorific Value - 3,500
-4,000K.cal/Kg
RDF Characteristics:-RDF Characteristics:-
Efficiency of Boiler :
Using Coal - 48%
Using RDF - 53%
12. • In India it comes in to the picture in 2003
• Dec, 20th
2003 of capacity 6MW by using 700 tons of MSW
generated every day in twin cities named as SELCO .
• Another plant Shriram Energy Systems Ltd producing 6 MW
of power at Vijayawada using RDF as fuel processed from
MSW generated in Vijayawada & Guntur cities
• SELCO is going to establish another 20 MW power plant in
Hyderabad
• Shriram Energy got permission to install another plant in
vizag.
DEVELOPMENTS & FUTURE OFDEVELOPMENTS & FUTURE OF
WTEE :WTEE :
13. • According to CPCB studies in India 70% of cities don’t
have sufficient facilities for transportation of MSW. By
using this WTEE we can avoid the MSW disposal
problem and we can save a lot of money which is going
to be wasted for transporting to outer yards of cities and
a lot of urban land which is wasted under dump yards.
• Not only in cities, this WTEE technology is also suitable
for rural villages where Agricultural and solid waste is
used to produce electricity.
