Compass Minerals U.K. is Britain’s largest supplier of natural rock salt, which is used by winter maintenance professionals to help thaw icy roads in wintry weather. We provide a range of services and bulk deicing salt products. Our underground rock salt mine in Winsford, Cheshire, is the U.K.’s largest and oldest working mine.

Compass Minerals actively engages with the communities where we work and live. Our community engagement initiatives include charitable gifts and volunteer opportunities. From conserving ecological landscapes and volunteering with local organisations to targeting our philanthropy toward causes that align with our Core Purpose, our aim is to make sure our presence benefits those around us.

Compass Minerals U.K. is ISO14001 certified, and we pride ourselves on our commitment to the environment and sustainability in everything we do.

Onsite at Winsford, we host a protective species program with ecological management zones located in our woodlands. These areas are protected and monitored annually by a professional ecologist to ensure the wildlife is not disturbed and that they have the best possible opportunity to thrive in their natural environment. We also have seven beehives located in our wildlife garden onsite with each hive containing around  50,000 honeybees. The beehives are cared for by a local beekeeper who visits each week.

Compass Minerals U.K. is also committed to our local community through charity fundraising events ran by our dedicated charity committee throughout the year.

More information is available in our Fiscal 2023 ESG Report, which highlights our progress on the environmental, social and governance matters of greatest importance to our company and our stakeholders.
