Green hydrogen

IndianOil is making significant strides in the green hydrogen sector and will be setting up its first ever Green Hydrogen plant at Panipat Refinery having 7 KTA capacity. Additionally, the Company has installed a facility for hydrogen dispensing at the Gujarat Refinery using hydrogen from the refinery unit.

Through a recent collaboration with NTPC Green Energy Limited, we are poised to significantly augment our renewable energy capacity by approximately 2 GW.

Water Management

Efficient management of water resources play a crucial role in building a sustainable future. By adopting sustainable practices, we can address water scarcity, protect aquatic ecosystems, support agriculture, and ensure reliable water supply for both human and environmental needs. In line with these objectives, IndianOil Refineries have been actively monitoring their fresh water consumption on a monthly basis.

Yearly targets for specific fresh water, treated effluent reuse, and specific effluent discharge have been strictly adhered to, resulting in an 89% recycling of treated wastewater in Financial Year 2022-23.

Reuse and Conserve

In an effort to promote water reuse, a notable project has been initiated at Mathura Refinery in the year 2022-23. The project focuses on utilising treated effluent from city municipal Effluent Treatment Plants (ETPs) for non-drinking purposes within the refinery. Currently, the refinery is replacing 8 Million Litres per day (MLD) of fresh river water with treated water. The project is currently undergoing final trials, and once fully operational, it will significantly contribute to reducing freshwater consumption and promote efficient use of water.

Similar efforts are being made at Gujarat Refinery, where a project for reuse of sewage treatment plant (STP) water is in its final stages. In the first phase, 21 MLD of treated water from Rajiv Nagar STP in Vadodara will be utilised within the refinery for non drinking and sanitation purposes. This project is aligned with the Government of Gujarat Policy and is expected to further enhance water conservation and reuse efforts in the region. Additionally, plans are underway for the commissioning of a second phase, which will result in a total reuse of 40 MLD of treated wastewater by 2025-26.

Keeping water consumption in check

Recognising the importance of efficient water management, a comprehensive water consumption study was undertaken for all IndianOil Refineries, including CPCL, in collaboration with the Centre for High Technology, under the Ministry of Petroleum and Natural Gas. The study, conducted in 2019, involved an extensive survey to assess consumption patterns and identify opportunities for enhanced water reuse. Based on the findings, short-term and long-term measures were developed, along with reduction targets and time bound action plans. These concerted efforts resulted in significant freshwater savings of 360 m3 /hr in 2022-23, against savings of 446 m3 /hr in 2021-2022.

Waste Management

To promote conservation of resources and minimise our imprint on the planet, it is essential to adopt efficient waste management practices across our operations. We strictly adhere to the Hazardous & Other Wastes (Management and Transboundary Movement) Rules, 2016, during the storage, recycling, transport and disposal of hazardous wastes generated within our facilities. By adhering to regulatory norms, we effectively reduce emissions and hazards associated with waste generation.

Mechanical and Chemical Recycling

Our emphasis on a circular economy allows us to actively manage waste through mechanical, chemical and biological recycling methods. Our research on mechanical recycling explores innovative applications for waste plastic-based bituminous roads, crumb rubber modified bitumen, poly bags for bitumen packaging, and paver blocks.

Additionally, our chemical recycling efforts involve the conversion of various categories of single-use waste plastic including thin carry bags, multi-layer packaging, thermocol and mixed plastic into liquid hydrocarbon oils, waxes, value-added chemicals, petrochemical feedstock and high-quality fuels compliant with BS-VI standards.

Reducing Plastic Waste

Furthermore, we have made significant strides in reducing our environmental footprint. For instance, we have increased the packaging capacity of our PTA plant bags from 1100 kg to 1150 kg, resulting in the reduction of approximately 11,000 jumbo bags and 30.8 MT of plastic per year, for recycling purposes.

IndianOil has launched an initiative called ‘Unbottled,’ which aims to promote the use of recycled PET bottles as a raw material for creating fabric, rather than sending them to landfills. This program has played a vital role in supporting the introduction of sustainable and environment friendly uniforms for around 3 Lakh IndianOil Retail Outlet Customer Attendants and Indane LPG Delivery Personnel. It is estimated that this initiative will annually recycle around 20 Million discarded PET bottles, making a significant contribution to reducing waste and promoting sustainability.

Effective Treatment of Hazardous Waste

When it comes to the disposal of hazardous waste, we adopt various methods. Spent catalysts containing recoverable metals are sold to authorised recyclers approved by local SPCBs (State Pollution Control Boards). Non recyclable spent catalysts are either sent to approved TSDFs (Treatment, Storage, and Disposal Facilities) or deposited at common Hazardous Waste Disposal sites. Silicate containing spent FCC (Fluidised Catalytic Cracking) unit catalysts are disposed of to cement industries, where they are utilised as feed admixture.

To handle oily sludge, we employ heat treatment and centrifugation techniques to separate the oil, which is then reprocessed within the refinery. The remaining sludge undergoes bioremediation to achieve an oil content of less than 1%. The bioremediated residual sludge is either disposed of for horticultural purposes or used within the refinery for construction purposes.

IndianOil has taken a pioneering step to contribute towards a circular economy by commissioning Wet Sulphuric Acid Plant at Haldia Refinery. This innovative initiative adds value to the elemental sulphur that refineries typically produce, promoting more sustainable and efficient utilisation of resources.

E-Waste Management

We also engage in e-waste management to ensure its proper disposal through buyback schemes, ensuring efficient recycling of electronic equipment. These initiatives help to fulfil our commitment to drive a circular economy and promote sustainable practices.
