About Us

Separation Technologies was founded in 1989 to develop commercial applications for a proprietary electrostatic separation process. By 1994, Separation Technologies was focusing on applying its separation technology to processing fly ash that could be used in high value commercial applications rather than being disposed of in landfills.

Since 1995, Separation Technologies has commercially operated the most successful worldwide fly ash separation systems producing ProAsh®. Separation Technologies leads the industry through innovation in technology, marketing, and commercial success.
