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.
