What this episode covers

Ken Rasmussen, Operations Director at Imerys, explains how the company mines and processes diatomaceous earth at its Lompoc, California facility, the world's largest diatomite mine. He details the material's critical role in high-purity filtration for pharmaceuticals, vaccines, and beverages, as well as its use as a filler in paints and plastics. Rasmussen discusses the site's century-long history, its integration with the local community, and how automation from partners like Royal Wholesale and Cyclone Air has improved process efficiency and purity control.
