Environment Initiatives & Measures at Nayara Energy

India has approximately 250 MMTPA of refining capacity, making it the 2nd largest in Asia. More than 60% of crude docks in the Gulf of Kutch, Gujarat make it one of the most strategic locations. Within the Gulf of Kutch, there is a small coastal town called Vadinar, which is home to one of the most complex refineries in the world, the cornerstone of Nayara Energy's existence

Nayara Energy's Vadinar refinery is India's second-largest, single-site refinery with an annual capacity of 20 MMTPA. It can process a diverse range of crudes and producing high-quality Euro IV, and Euro VI grade products and Bharat Stage (BS-VI) compliant fuels that meet international standards. This brings us at par with global emission standards.

Nayara Energy owns and operates an integrated, state–of–the–art Marine Oil Terminal located at Vadinar coast, Gujarat within the conservancy of Deendayal Port Authority, the largest port in the country. The Terminal has a capacity of 41 MMTPA and can handle both crude oil and petroleum products. The facilities include an off-shore single point mooring (SPM) capable to handle crude tankers up to size 350,000 DWT and two berths capable of accommodating tankers up to 100,000 DWT. It is located close to India's first Marine National Park. This area serves as nature's laboratory for studying the complexities and integrity of living and non-living organisms, with over seven varieties of mangroves, 52 coral species, 80 bird species, and other abundant resources, making the area rich in biodiversity.

The key initiatives for safe and robust operation and maintenance regime include:

  • Well-defined ship acceptance criteria.
  • Ship shore environment Checks.
  • Strict compliance with OCIMF, OISD and ABS guidelines.
  • Highly experienced, trained, and motivated Human resource

Nayara Energy is aware of its vast responsibilities, which include social and environmental duties and has developed a well-defined Environmental Management System for mitigating the impacts on the environment. Some of the important measures include:

Mangrove plantation

The plantation of mangroves covers an area of 175 hectares, and another 200 hectares are in the final stage of plantation in the Marine National Park/Sanctuary area.

Oil Spill Preparedness and Response

We strongly believe that prevention is better than cure. Therefore, our offshore assets comply with strict retirement criteria under ABS classification, and we have a robust oil spill management mechanism in place with OSDCP, Tier-I OSR equipment, and trained manpower. We also have a Mutual Aid Agreement for resource pooling with the Port Authority and nearby oil handling agencies.

Air Pollution Prevention / Control Measures

Refinery fuel gas, natural gas and fuel oil containing low Sulfur are used in heaters and furnaces. We have installed various systems and equipment in process units for emission control across the refinery.

Hazardous Waste Management

We are committed to the effective management of waste generated in our refinery. To this end, we have implemented documented management procedures for both hazardous and non-hazardous waste management. Our waste management procedure is strictly followed, and we strongly believe in the maximum utilisation of waste. Therefore we adopt the principles of reduce, reuse, recycle, co-processing, preprocessing, and so on for the disposal of any kind of waste

Greenbelt Development

The main objective of setting up a green belt is to mitigate fugitive emissions or accidental releases, control soil erosion, facilitate wastewater utilisation, control noise pollution, and improve the aesthetic view of the refinery. Nayara has developed a well-established greenbelt in the 410 Ha area having more than 300,000 plants.

Marine Environment Monitoring

Comprehensive annual ecology monitoring through the CSIR- National Institute of Oceanography (CSIR-NIO) has been conducted since the commissioning of the facilities. The monitoring includes water and sediment sampling and analysis at identified stations. Coral, Mangroves, and other biota monitoring are also covered under the annual monitoring. The monitoring covers an area of approximately 200 km2, spanning seven coastal stations as well as Kalubhar, Narara Island, and the intertidal areas of Vadinar. The annual monitoring is compared with the baseline data. To date, no gross changes have been observed due to our operations for more than 16 years. In addition, monthly marine environment monitoring is done through the Gujarat Institute of Desert Ecology (GUIDE) for water, sediment quality and biological characteristics

Wastewater Management

The wastewater from different production units of the refinery is collected and treated at the wastewater treatment plant. The entire quantity of treated wastewater is reused/recycled for various purposes, such as cooling towers, fire water make-up, green belt, and feed to the RO plant. More than 95% of Treated wastewater is reused inside the Refinery.

Environment Quality Monitoring

Nayara Energy has installed two Continuous Ambient Air Quality Monitoring Stations. Continuous stack emissions, ambient air quality, and effluent monitoring are connected to CPCB. Nayara has also implemented Leak Detection and Repair Program for monitoring fugitive emissions. Groundwater quality monitoring is also carried out within and outside the refinery.

Rainwater Harvesting

Nayara has also developed six reservoirs/ponds within refinery premises to store and recharge groundwater. The total capacity of these ponds is 625,000 m3

Due to its incredible location and highly complex refinery, Nayara Energy Marine Terminal leverages its assets and experience to operate most efficiently and effectively. It has completed over 6000 days of safe operations and has handled more than 5400 ships without any incidents of oil spills. This speaks volumes about our perseverance towards Environment Protection. We are dedicated to meticulous work to keep our coast and waters among the safest and purest in the world, taking into account the incredible biodiversity of the area
