POLY4 Production

POLY4 Production

The Anglo American Woodsmith Project is setting a new standard for sustainable mining.

Anglo American’s Woodsmith Project is a deep mine and associated transport, processing, and shipping infrastructure development under construction in North Yorkshire, England, UK.

It will extract polyhalite to produce the nutrient-rich POLY4. Bringing this world-class mine to fruition will help meet the world’s ever-increasing need for food from ever-decreasing areas of available land, with a highly efficient, effective, and low-carbon fertilizer.
