Our story
A Texas manufacturer with a public-benefit mission.
We’re a Texas-headquartered chemical manufacturing company and a chartered Public Benefit Corporation centered on planet, people and profit. Hoigen-C™ is designed to perform like petrochemical acrylonitrile—and in some applications, outperform it.
We’re building a future where using carbon-negative technologies is a lower-cost alternative to today’s standard CO₂-generating processes.
