Bengaluru airport gets integrated solid waste management centre

The Kempegowda International Airport (KIA) in Bengaluru on Wednesday inaugurated its in-house Integrated Solid Waste Management Centre (ISWMC). As one of India’s busiest airports, KIA generates approximately 24–26 tonnes per day of solid waste across terminals, airside operations, commercial outlets, and allied facilities currently.

The Bangalore International Airport Ltd. (BIAL) said that the ISWMC enables scientific, end-to-end waste processing at source, enhancing operational control, reducing reliance on external handlers, minimising transportation-related environmental risks, and contributing to lower emissions, improved compliance, and greater operational resilience.

“With the facility in place, the airport expects to reduce landfill disposal to 2–3% of total waste, enabling 97–98% of waste to be recycled or recovered through in-house processes and authorised partners,” BIAL said.

Designed with a total processing capacity of 77 tonnes per day (TPD), the ISWMC is designed to manage both organic and inorganic waste streams. Organic waste, up to 50 TPD, is treated through bio-methanation technology, converting biodegradable waste into compressed biogas (CBG) for use in airport kitchens, along with liquid organic manure and compost to support landscaping requirements. The remaining 27 TPD of inorganic waste is processed through advanced segregation systems, with recyclables directed to authorised recycling partners and recoverable material utilised for co-processing in the cement industry.
