NEW DELHI. To mark World Environment Day 2026, IndianOil’s Refineries Division showcased the successful operation of its first-of-its-kind Green Sewage Treatment Plant at the Haldia Refinery, presenting it as a sustainable blueprint for potential replication across its national network. The facility, which has been fully operational since January 26, 2026, was highlighted in New Delhi through an audio-visual presentation by Arvind Kumar, IndianOil Director of Refineries. Developed in collaboration with the Society for Innovation and Entrepreneurship at IIT Bombay, the plant utilizes Integrated Wetland Technology to treat wastewater using natural processes like wetland vegetation, filtration media, and microbial activity. Over its first four months of continuous performance, this nature-based system has proven highly effective, delivering significantly lower power consumption, reduced greenhouse gas emissions, minimal maintenance requirements, and recycled water that is immediately reused for local horticulture.
