Refuse Derived Fuel consists of material which is not easily biodegradable such as Paper, Plastic, Coir Pith, Jute, Textile Material, Fibrous Material and other combustible material. These materials are segregated specifically for use as alternate fuel material in boilers, cement kilns and other energy intensive industries where conventional/fossil fuels are a costly affair. |
RDF Processing |
Segregated material is dried, crushed, screened and packed/bailed, used as substitute to conventional fossil fuels in boilers.
- Total moisture
- Ash
- Chlorides
- Sulphur
- Volatile matter
- Gross Calorific Value
- Av. Concentration of PM (mg/NM3)
- SO2 concentration (ppm)
- NOX concentration (ppm)
|
RDF can be used by |
- Cement Industries; alternate fuel to coal/fossil fuels for reducing carbon footprint
- Biomass Power plants
- Energy intensive, fossil fuel consuming industries can use this as alternate fuel.

Reception of Waste
- Vehicles, drivers and payload weight logged
Tipping Floor/ Pre-sorting
- Vehicles directed to displace the waste on a secure platform in specified piles.
- Via cranes, bobcats, dozers and the staff, waste fed to the trommels for separation.
- On separation smaller particles sent to the Windrow platform.
- The larger particles sent to the refuse derived fuel (RDF) bunker.
Windrow Platform (Aerobic Composting)
- Organic waste composted for a month via the help of EM culture.
- Continuous overturning & transfer of the compost via cranes.
- Different heaps signifying different maturation levels.
Monsoon Shed (Aerobic Composting)
- The composted material is fed through two successive trommels for further separation.
- The Smaller particles are moved to the curing shed.
- The larger particles are either sent to the landfill or to the RDF bunker.
Curing Shed (Aerobic Composting)
- The material is spread out to cure
- The material is then passed through a final trommel as well as a de-stoner.
Storing & Packing facility:
- The composted material which is of a consistent fine texture is now stored in heaps.
- The EM culture coupled with the well timed process yields a nutrient rich, safe byproduct
- The material is packed and sent to fertilizer companies.
Recycling Shed:
- Segregation at source is not always carried out by, resulting in mixed solid waste.
- Hyderabad Integrated MSW Limited secondary segregation at the site to ensures removal of part of the plastics.
- Plastic Granulation is also carried out.
Leachate management Systems:
- Prior to the handing over of the Jawaharnagar site, the acreage was used as a dumpsite which spawned unknown amounts of leachate and outflow into the local water bodies.
- Lake Malkaram for example has been contaminated with said leachate.
- Over time Hyderabad Integrated MSW Limited, has brought down levels of leachate in the lake through cleaning efforts and created barriers to prevent the leaching out of liquids.
- The site mapping has provided us with the gradation and the general flow of the leachate from the past dump to begin damage control.
- Several solar evaporation ponds are used to maintain and check the flow of leachate along with concrete reinforced channels.
Leachate Treatment Plant:
- Leachate treatment facility.
- Through Curing, Reverse Osmosis and UV treatment, the leachate generated can be converted to a usable form of water.
Projects
- RDF bunker
- RDF fluff, or briquettes, to be used as fuel.
- Waste to energy plant, to feed energy back into the grid.
- Given our extensive knowledge with waste management, HiMSW has a proposal to start a training school, to equip future employable individuals with MSW training.
Landfill
- Prior to the setup of Hyderabad Integrated MSW Limited, the Jawaharnagar site was used as a 350 acre dumping grounds.
- All of the city's garbage was essentially brought to the site and piled high.
- After a few years of dedicated effort by our committed staff and worker, we are proud to say that the site and the intended infrastructure & facilities are coming along as schedueled.
- Currently a fraction of the material bought to the site is disposed of in a landfill.
- The landfill follows all of the MSW 2000 rules, including multiple liners, compacted soil and leachate monitoring wells to assess the nature of the landfill & the safety of the surrounding land.
