Over the years, HAL has proactively undertaken various initiatives to support community development and minimize its environmental footprint.
Water Conservation
- Rainwater Harvesting (RWH) systems have been installed at all HAL locations, with suitable buildings identified for rainwater collection and storage. The harvested water is utilized for gardening and other non-potable applications.
- The company actively promotes water conservation through measures such as fixing leaks and raising awareness.
- HAL ensures that its operations remain environmentally responsible. Sewage and effluent treatment plants have been set up, with treated water being reused for gardening and non-potable purposes, in full compliance with local Pollution Control Board regulations.
- Afforestation is a continuous effort across various HAL divisions, including those in Bangalore, Lucknow, and Hyderabad, contributing to green spaces within urban environments.
- As part of its CSR initiatives, HAL has collaborated with the International Association for Human Values (IAHV) to rejuvenate the Kumudvathi River in Tumkur District, Karnataka. Around 25,000 saplings have been planted in the catchment area to enhance water retention.
Energy Efficiency and Renewable Energy
- Energy conservation is an ongoing priority at HAL. Numerous initiatives have helped reduce energy intensity, including:
- Refurbishing furnace insulation
- Installing Variable Frequency Drives (VFD) in air compressors and ventilation systems
- Using solar water heaters
- Enhancing the efficiency of air compressors and HVAC systems
- Replacing reciprocating compressors with screw compressors
- Upgrading old air conditioners to energy-efficient models
- HAL is actively transitioning to LED lighting across all its locations, with approximately 65% implementation completed.
- In addition to improving operational energy efficiency, HAL is investing in renewable energy. The company has committed to installing 50 MW of renewable energy capacity to reduce its carbon footprint. So far, 46 MW of wind and solar power plants have been commissioned, generating approximately 775 lakh units of electricity in 2019–20 and preventing about 73,000 tons of CO₂e emissions.
- Key solar and wind power initiatives include:
- A 3.5 MW solar power plant at HAL Airport, Bangalore, equipped with a single-axis tracking mechanism for enhanced efficiency and reduced glare for aircraft.
- Ground-mounted solar plants of 15 MW and 6 MW capacity at Nasik and Koraput divisions, respectively.
- A 6.3 MW wind power plant at Harapanahalli, Karnataka, commissioned in March 2016.
- An 8.4 MW wind power plant at Ilkal, Bagalkot District, operational since December 2018.
- Rooftop solar installations across various HAL divisions, contributing over 7 MWp capacity.
Waste Management
- As part of its Municipal Solid Waste (MSW) management efforts, HAL has installed Organic Waste Converters (OWCs) in Bangalore townships to convert kitchen and organic waste into garden manure, supporting the goal of zero waste disposal.
- To further enhance solid waste management, two biogas plants (500 kg/day and 1000 kg/day capacity) have been installed at the Central Test House (CTH) area in Bangalore, processing canteen waste to generate biogas for cooking.
- Waste segregation at source has been implemented across all HAL locations to ensure efficient waste management.
- HAL operates a Paper Recycling Unit in Bangalore, processing up to 75 kg/day of waste paper to produce files, folders, and stationery items—an initiative aimed at tree conservation.
- The company actively promotes waste management awareness within the community through activities such as drawing and essay competitions, skits, and mini-marathons under the Swachh Bharat mission, with top management participating in these campaigns.
- HAL has been recognized by the National Productivity Council with a Certificate of Appreciation for its commitment to the principles of Reduce, Reuse, and Recycle.
Through these initiatives, HAL continues to integrate sustainability into its core operations, reinforcing its commitment to environmental stewardship and responsible corporate citizenship.
