Right from the initial stages, the Company has always given utmost attention to environmental care and protection. Kochi Refinery is committed to a green environment and year after year, we take up several environment centric initiatives to remain in the forefront as a Corporate Green Ambassador. Various environmental initiatives are being taken to minimize the impact of refinery operations on emission, effluents, and solid waste generation. Extensive anti-pollution measures are incorporated in the design stage of each unit. As an ISO 14001 company, Kochi Refinery’s Green Environmental Management Systems (GEMS) conform to international standards.

Kochi Refinery has advanced Effluent treatment plants (ETPs) to ensure the effluents meet Pollution Control board (PCB) norms. Additionally the RO based DM plant, ensures maximum recycling of treated water and minimum discharge to water bodies. Kochi Refinery has also developed multiple rainwater harvesting systems with a view to conserving water resources. One of the rain water harvesting systems has been developed in 18.83 acres area within the Refinery premises with a water storage capacity of 2, 87,340 (M3), making it one of the largest rainwater harvesting systems in Kerala.

Hydrotreating units along with Sulphur Recovery Units support recovery of Sulphur from the product and offgas streams. This ensures SO2 emissions are minimum from the internal fuels and minimizes the vehicular emissions. Tail gas treatment unit (TGTU) which was installed along with the Sulphur Recovery unit of IREP helps to achieve 99.9% recovery of sulphur. To reduce particulate matter emission from the Fluid Catalytic Cracking (FCC) unit, an electrostatic precipitator was commissioned in 1985 and KR is the first Refinery in India to install this facility. Advanced process control (APC) system was implemented in hydrogen network for decreasing hydrogen flaring and in process units for optimizing fuel consumption which helps to reduce emission. Reduction furnace for conversion of ammonia stream to nitrogen in order to reduce NOx emissions. The refinery has also added the MSBP facility to meet Euro VI norms. The refinery has also taken extensive care in managing the potential dust pollution from its coke handling systems (COKE DOME). From the point of generation to dispatch, systems are implemented to avoid any dust escape.

Kochi Refinery has developed wide range of lush green belts in and around the Refinery with various parks including Butterfly parks, Rainbow park and Eco park to ensure a healthy ecosystem and to maintain a cleaner and greener environment.
