If prevention or elimination of waste is not possible, we minimize waste by applying our waste hierarchy principles. Our waste management approach is built on the mitigation hierarchy principle of source reduction, reuse, recycling/recovery, treatment and responsible disposal. This principle is incorporated into the design and operation of all our facilities and includes the elimination, change or reduction of operating practices which result in discharges to land, air or water. In 2023, we developed our Waste Management Reduction 2030 Roadmap, which aligns with new federal and local authority strategic objectives in the UAE. As part of our roadmap, we are exploring the use of technology to reduce waste, manage resources efficiently and deliver cost savings. We are working towards a comprehensive circularity strategy. Waste generation 2022 2023 Non-hazardous waste generated (kilotonnes) 115 96 Hazardous waste generated (kilotonnes) 40 46 An ecological alternative to landfill Dealing with waste offshore is an industry challenge due to the limited space to treat and store waste. Decomposing waste builds up bacteria and germs that could potentially be harmful to the health of our workers and the environment. Weather conditions can make it difficult to transport waste safely. Together with Inventive Environmental Solutions — a joint venture focused on waste processing systems and initiatives — we have piloted technology to reduce the volume and weight of non-hazardous waste generated offshore. The technology uses friction to generate heat that causes moisture to evaporate as steam. This sterilizes the waste, killing any harmful germs and bacteria and simultaneously reduces its mass. The processed waste is dispensed into a holding chamber containing a vacuum bag. The pilot at one of our offshore artificial islands resulted in an 80% volume and 45% weight reduction in the treated waste, leading to environmental and health benefits as well as cost savings. Spills prevention Preventing hydrocarbon leaks and spills is a key priority for ADNOC. We focus on prevention, preparedness, incident reporting and response, underpinned by robust health, safety and environmental standards. We proactively maintain the integrity of our assets throughout their lifecycle. We have procedures in place that set out the requirements for effective inspection and maintenance of equipment, risk management and competence. Across our operations in 2023, two hydrocarbon spill incidents (>1 barrel) were recorded. When an onshore spill is reported, we deploy immediate measures to contain and recover the spill. We remove any contaminated sand and transfer it for treatment and safe disposal. We remediate any contaminated soil using a number of onsite technologies such as soil vapor extraction and air sparging. In the case of an offshore spill, we immediately deploy oil spill response resources and vessels. Oil spill trajectory modelling informs our decision making and guides response operations. For more information on our emergency response and crisis management approach, refer to the Emergency Response and Crisis Management section and the Process Safety section in the Keeping our people safe chapter of this report. Our operations generate non- hazardous and hazardous waste streams. We are committed to treating and managing both types safely, from generation to disposal. Any hazardous waste is sent to a BeAAT facility (a central environment protection facility in Abu Dhabi) which uses proven technology for the safe treatment and disposal of hazardous waste. Where applicable, a proportion of this waste is sold to approved third parties for recycling and/or reuse. All non-hazardous waste is classified and segregated as per the requirements of the EAD and Tadweer (the Abu Dhabi center of waste management). Recyclable waste is sent for recycling or composting. Spill incidents Waste management and circularity In 2023, 19,929 tonnes of waste were diverted from landfill sites. The remaining non-hazardous waste was sent to municipal landfill. Waste transfer is overseen by the Bolisaty system, a smart, integrated waste database developed by the Tadweer Group. We undertake a combination of targeted initiatives to increase the amount of waste diverted from landfill sites. These initiatives include the recycling of waste oil and electronic waste, sending waste offsite for reuse and recycling, composting, and converting cooking oil to bio-diesel. Through Borouge, a joint venture with Borealis, we are progressively implementing a sustainable plastic waste management model, which we expect will result in a greater net positive impact on business, society, and the environment. 54 55 Energy for Life
