ICL Growing Solutions Boulby

The World's Only Polyhalite Mine

ICL Growing Solutions Boulby is situated on the picturesque Northeast coast of Britain, within the North York Moors National Park, and is the site of ICL’s polyhalite mine. Polyhalite is the unique, natural, multi-nutrient mineral that is mined, crushed and screened to produce Polysulphate fertilizer for the agriculture, turf, and ornamental horticulture sectors.

Mine construction commenced in 1969, with potash and salt production starting in 1973. Following the discovery of polyhalite at Boulby, the mine transitioned from potash to Polysulphate in 2018. Production has increases as demand grows for this new product. In 2023 the mine processed 1,000,000 tonnes of Polysulphate.

The Source of Polysulphate

Three distinct grades of Polysulphate are produced at Boulby: Polysulphate Standard, Polysulphate Granular, and Polysulphate Mini. In addition, ICL Boulby also produces ICL PotashpluS, a granular product that consists of an equal blend of Polysulphate and ICL Potash. All these products are transported by direct rail link to Teesport, where they are shipped to growers worldwide.

Activities at ICL Growing Solutions Boulby

ICL Boulby: the Source of Polysulphate

From 1.2 km below the North Sea, off the northeast coast of the UK, ICL mines and extracts Polysulphate for processing and global distribution. The minimal processing results in a very low carbon footprint fertilizer.

Technologically Advanced

ICL Boulby is a technologically advanced mine. Located within a national park means the mine must meet stringent environmental conditions, holding multiple internationally recognized certifications, including ISO 9001, ISO 14001, ISO 45001, and ISO 50001.

UK’s Deepest Mine

The mine at ICL Boulby is the deepest in the UK and the second deepest in Europe, mining Polysulphate from the ancient dried-up Zechstein Sea at around 1,200 meters below the North Sea and 8 km off the UK coast.

Unique Research Opportunities

ICL Boulby also houses the Boulby Underground Laboratory, a multi-disciplinary deep underground science facility operated by the UK’s Science & Technology Facilities Council (STFC) and working in partnership with ICL UK.

Focus on Sustainability

A series of significant efficiency improvements at the mine has recently reduced the already low carbon footprint of Polysulphate by more than 90%. With a carbon footprint of just 0.0029 kg CO2e per kg of product, Polysulphate stands out as a prime eco-friendly choice for farmers.

Global Connections

The direct rail link from the mine to ICL’s deep-water berth at Teesport ensures excellent connectivity. Polysulphate can be loaded and shipped to our customers around the world so they can benefit from ICL’s Polysulphate fertilizer.
