Omya gets full waste permit

Vermont’s Agency of Natural Resources on Friday issued a solid waste permit to Omya Inc. that allows the company to dispose of its calcium carbonate waste. The full certification allows Omya to dispose of its marble tailings in a lined “tailings management area” on its Florence property. Omya will build a disposal facility that includes an engineered plastic geomembrane liner and leachate collection system placed over the existing tailings material. The system will collect any water and recycle it back into the plant through a dewatering process.
