This document discusses using waste-to-energy (WTE) technology to solve Colombo's garbage problem. It notes that Colombo lacks a proper solid waste disposal mechanism and dumps garbage at Bloomendhal road. WTE technology was originally developed in Germany and involves incinerating solid waste to produce energy. The technology could provide benefits like reducing costs for Colombo Municipal Council and generating additional revenue from recycling, while addressing issues like health hazards from current dumping. However, adopting this technology would require a high initial investment and know-how.

2. INTRODUCTION ABOUT THE CITY OF COLOMBO
 Capital city of the paradise island Sri Lanka
 Vibrant city
 Total population counts up to 1 million
 Heavily anticipates foreign investments
 Lacks of proper solid waste disposal mechanism

3. SRI LANKAN SITUATION
 Biggest garbage dumb positioned at bloomendhal road
 Responsibilility of CMC.
 Rapid increase in the demand to Electricity
 Enviorenmantal Damage caused due the Hydro Power
Supply
 High increase in Fuel prices causing to high electricity
generating costs

4. PROBLEMS WITH THIS SYSTEM
 Serious health hazards
 Mosquito breeding
 Adversely affect to economy
 Heavy flooding

5. WASTE TO ENERGY TECHNOLOGY
 Originally found in Germany in 20th century
 Singapore is the country which is most successful in
implementation
 Involves changing various elements of solid in to a form
of energy (W T E incineration)

6. OPERATING OF TECHNOLOGY
 Waste transported into a waste incineration facility
 Solid waste will be put to a special burning chamber for
combustion
 Boiled water will be used to drive the turbine
 Ash from the burning process can be used for land filling
purposes
 All gases were cleaned before emitted

7. OPERATING OF TECHNOLOGY… CONT..


8. POTENTIAL BENEFITS
 Cost effectiveness
 City attraction
 Reduce the expenditure of CMC
 Additional Revenue from recycling
 Reduce the environmental impact

9. COSTS
 High initial investment
 Technological Know How
 Waste transportation cost
 Operations and maintenance
