At Santos, we aim to keep waste generation to a minimum through greater efficiencies, reuse and recycling, thereby reducing our environmental impacts.
Efficient waste management can present opportunities to improve environmental outcomes, increase product recovery and reduce operating costs.
Our Environment, Health and Safety Management System waste standard defines the minimum acceptable standards for managing waste generation, transportation, storage, handling and disposal at all our sites and for all our activities. We use a waste management hierarchy approach to minimise waste production and disposal and ultimately reduce environmental impacts. The waste management hierarchy identifies waste management methods ranging from most to least preferable (avoid, reduce, reuse, recycle, treat and dispose). The standard also defines the process we use to identify and mitigate potential risks associated with waste management and develop and implement site-specific waste management plans. We also work closely with our suppliers to reduce waste in our supply chains.
Santos is focused on ensuring a consistent approach to waste management at all of our facilities so that improvements extend to all sites and can be measured with confidence.
Projects are ongoing to improve recycling and minimise waste volumes across all our operating areas.
We publicly report our waste volumes in our annual sustainability report.
FAIRVIEW DRILLING FLUID RECYCLING
An innovative system for drilling fluids is helping to minimise the disposal of waste water and cut consumption of surface water requirements for drilling, completions and construction at Fairview.
MOOMBA SLUDGE TREATMENT PLANT
At Moomba, we completed work on a permanent, fully enclosed sludge treatment plant to replace temporary facilities. The new plant will operate more efficiently, enabling oil from cleaning out vessels and pond skimming to be captured and recycled.
Management of Moomba landfill has also been upgraded, including installation of an impermeable lining at the base to prevent potential leakage.
