About Thar Process

Providing CO2 extraction and purification solutions since 1990, Thar follows the 3 P’s Principles: People, Planet, Profit. Utilizing and recycling up 1000 times before losing it back to the atmosphere, CO2 is Thar’s choice of solvent because it is non-toxic, non-flammable and actually sterilizes the products that it touches when in a supercritical state. It's better for the people who operate and consume these products while generating profits for Thar and its clients/partners.


cGMP Certified and employing more than 120 people in 3 countries, Pittsburgh-based Thar is the global leader in CO2 technology and equipment for the hemp industries.  Thar’s expertise includes engineering headed up by Dr. Chordia, Jeff Wright and Sashi Ramesh plus chemistry and formulations, headed up by Drs. Shaikh and Lupoi.   Chief Revenue Officer Todd Palcic and CFO Greg Imberlina round out the team with operations managed by Rick Mascara and Keith Douglas.

With its proprietary technology, continuous R&D and toll processing services complementing its expertise in the bench to production-scale equipment, Thar offers its customers a single-point-of-access for process-scale, CO2 extraction, and purification solutions.
