Karnataka Urban Infrastructure Development and Finance Corporation (KUIDFC) gives an insight on their initiatives towards the establishment of solid waste composting facilities for BBMP
The Government of Karnataka (GoK) has proposed to establish Solid Waste processing, treatment and disposal facilities with an objective to improve the quality of Solid Waste Management (SWM) services in the Bruhat Bengaluru Mahanagara Palike (BBMP) area. An Empowered Committee (EC) under the chairmanship of ACS (UDD) and MD, KUIDFC as Member Secretary, has been constituted. The Government has allocated `.440 crore for this project. The civil works are to be implemented through Karnataka Rural Infrastructure Development Ltd. (KRIDL) on Deposit contribution basis.
The Solid Waste processing, treatment and disposal facilities are established in six sites and upgradation of KCDC plant. These plants can handle about 2300 TPD of waste. All necessary waste processing equipments, machineries and waste handling vehicles are procured. KUIDFC has engaged National Institute for Interdisciplinary Science and Technology Council of Scientific and Industrial Research, Thiruvananthapuram as consultants, for providing tailor made solution for controlling odour inside and outside the sheds. Also, a pilot leachate treatment plant with reverse osmosis technology was taken up at Doddabidarkal plant and commissioned.
In order to operate and maintain these plants, private operators are appointed through a “Performance Based Management Contract” for carrying out day-to-day operations in an efficient and effective manner.
The state-of-the-art facilities are created with the following features
• Closed shed for year-round operations to arrest environmental pollutants and reduced leachate generation
• Odor control measures – provision for air ventilation system and bio filters
• Pit system for collection and emergency storage of waste during emergency, reduced littering & spillage and reduced waiting time of the tipping vehicles.
• Compound wall (3 m High + 2m Barbed Wire Fencing)
• Pre-engineered building (PEB) sheds designed for potential solar panel installation
• Windrow turning by grab mounted excavator for better aeration
• A curing section with multiport distributor for enhanced compost production
• Chain conveyors for transport to prevent waste spillage
• Automation of equipment to minimize human intervention
• Hydraulic Tippers and Tractors to ensure no material spillage happen on the floor of the plant
• Installation of Air Density Separators for separating non-biodegradable, recyclables and inert from the oversized rejects
• Land development for better aesthetics and plantations / green belt development for creation of buffer around the plant to aid greater acceptability among nearby residents
• Rainwater harvesting and recycling of leachate
• Provision for leachate treatment plant
• Approach road and internal concrete roads with drains, lighting facilities, parking areas
• Groundwater monitoring wells for regular water quality monitoring
• Compacting and baling units for RDF
• Establishment of laboratories for testing
Waste to Energy
The Government of Karnataka has proposed to set up four regional power generating plants out of solid waste at Mysuru, Hubballi – Dharwad, Mangaluru and Kalaburgi on Public Private Partnership basis. KUIDFC is appointed as the Nodal Agency for the project. A committee has been constituted under the chairmanship of DMA for monitoring the same. Infrastructure Development Corporation (Karnataka) Limited are the project consultants. The preparation of feasibility reports is underway.
