Our main sources of non-hazardous waste include soil from excavations and drill cuttings (materials removed from the ground during drilling such as rock and soil). Where possible, hazardous waste – such as process water from our chemical plants and refineries – is treated on-site or removed for treatment or safe disposal.


When we decommission a refinery onshore, we safely remove our equipment and restore the land. Decommissioning an offshore facility can be more complex, so we take time to identify an appropriate solution that balances environmental, safety and economic factors.

If possible, we recycle platform components so they can be reused on land. We have set a target to recycle 97% of the above-water components of our Brent field platforms in the North Sea, our largest decommissioning project to date.
