At SO4, environmental responsibility isn’t a checkbox. It’s at the core of everything we do. Our operations at Lake Way focus on extracting and processing naturally occurring brine using one of the lowest-emission methods for producing commercial Sulphate of Potash (SOP) anywhere in the world.
Unlike the conventional Mannheim process, which supplies 40% of global SOP and emits significantly more carbon, our brine-based technique cuts emissions by over a third. It's cleaner, smarter, and built for a more sustainable future.
We back this with a robust Environmental Management System (EMS) that ensures full regulatory compliance while driving continuous improvement in key areas:
Every part of our environmental performance is actively monitored through comprehensive, state-aligned management plans. These plans include clear outcomes, contingency measures, and regular tracking to ensure we're always on course, or adjusting when needed.
We also collaborate closely with Traditional Owners, regulators, and environmental experts to safeguard the unique ecosystems of Western Australia's Goldfields region. Our commitment goes beyond compliance. We aim to set a new benchmark for environmental leadership in the global potash industry.
