6 Hyderabad Waste to Energy Project Project supported by: Municipal Corporation of Hyderabad TDB, TIFAC, Department of Science & Technology Government of India. IREDA MNES NEDCAP, Government of Andhra Pradesh AP & Central Pollution Control Boards

7 Technology of M S W Processing The breakthrough in the segregation and processing of the heterogeneous MSW in Hyderabad is all set to revolutionize the MSW processing sector. Technology Information Forecasting and Assessment Council (TIFAC), Department of Science & Technology, Government of India has granted permission to SELCO to adapt the technology developed at the Mumbai pilot plant. SELCO along with TIFAC has further developed the designs required for scaling up, optimization, energy savings etc. The Andhra Pradesh Technology Development & Promotion Centre (APTDC) has provided the overall project guidance and supervision in the implementation of the project.

9 Salient Features of Hyderabad MSW Processing Project Plant Capacity Input: 400 MTPD of Unsegregated MSW Output: 210 MTPD of Refuse Derived Fuel (RDF) in the form of fluff/pellets/briquettes Land 10 acres of MCH land allotted to SELCO. 30 years lease with annual lease rent at 5% of registration value of land. Permitted the company to mortgage to financial institutions. Capital: Rs11.25 Crores. Plant has been commissioned by SELCO and operating since 1999.

11 Process Moisture Reduction: Green house: Solar thermal panels on roof directly generate hot air with a temperature of ambient +25 degree Celsius. MSW is retained in the green house for a day and continuously disturbed with the help of front-end loader. Moisture reduced from 45% to about 15%. Conventional Rotary Dryers/Flash Dryers

12 Separation: Belt conveyors: Process Very bulky material like tires, pipes etc. are removed manually Magnetic separator Ferrous particles are separated. Air Density Separation (ADS): Heavier items like stone, glasses, coconut shells etc., will get rejected Lighter material which generally form the combustible matter is conveyed upwards due to positive pneumatic pressure. Rotary trammel Fine sand along with biomass attached to it gets separated. Finer rejects form a useful by product, which can be used as a biofertilizer The output of the rotary trammel is the clean combustible matter.

13 Process Size Reduction: Combustible matter in the MSW is reduced to uniform size in hammer mill The output is in powder /fiber form which is generally referred as RDF fluff. Densification: RDF pellets have a diameter of 8 to 20 mm. Briquettes of mm diameter, mm length.

14 RDF (Refuse Derived Fuel) Characteristics Calorific Value: Kcal/Kg. High Volatile Matter (> 60%) Less fixed carbon ( 12-18%) Less ash content ( 10-15%) Moisture: (7.2 %)

15 Salient Features of Power Plant based on Processed Hyderabad MSW Location: Shadnagar, 55km from Hyderabad Capacity of the Plant 6.6 MW Exportable power: 5.9 MW Power Purchase Agreement: APTRANSCO 20 years. Sub-station : 33/11 KV sub-station located 3 Kms away from power plant Capital Cost: Rs33.33 Crores

16 Power Plant: Power plant is connected with APTRANSCO grid and generation of power from MSW is no more a myth in our country. Several modifications have been made in the boiler to take care of the incineration of RDF. Special protective measures were also taken up to protect the boiler from firing effects of RDF. Another special feature of power plant is the provision of Air Cooled Condenser in place of conventional water-cooled condenser.

18 Clean/Eco-Friendly Technology Major advantages: The technology provides yet another source of renewable energy similar to that of wind energy and solar energy for power generation best suited for energy intensive Indian Cities. RDF is a Coal substitute with a calorific value of about 3500 Kcal/kg. Unlike the coal, it has no shellac and has less ash content. The emission characteristics of RDF are superior compared to coal with less NO X, SO X, CO & CO 2. The burning of RDF in place of coal reduces the Green House gases. The Municipal corporations also reduce the capital expenditure on construction of Sanitary Landfill sites, as they are capitalintensive projects.

19 The municipal solid waste should be considered as alternate source of energy. Processing of heterogeneous, low calorific and high moisture content MSW is the most critical part of the technology, which may appear as a simple process. One-decade of efforts including four years of operational experience paved the way for the production of good quality of RDF. This nascent technology of RDF production has stabilized and commercial replication started in the country indicating the success achieved.

20 Benefits MSW processing technology offered to several companies in India. Major Cement Industries are coming forward to set up MSW processing plants for using the RDF in their cement plants as alternate fuel. Sufficient technical data for the design & development of second generation WTE plants. Another source of alternative energy Social upliftment of the Rag pickers as semi skilled workers
