Our Journey

  • 1990

    Thar is founded by Dr. Lalit Chordia.

  • 2007

    Thar built and commissioned the world’s largest industrial scale supercritical chromatography system, SFC-600. The system is currently being used in Malaysia to separate and purify micronutrients from palm oil.

  • 2008

    Thar was awarded a $2 million grant by the National Institute of Standards and Technology Alternative Technology Program for the development of a novel biodiesel technology that reduces that use of toxic substances and offers a clean, continuous, and economically viable production process.

  • 2012

    Thar announced the opening of its CO2 supercritical toll processing plant in the Pittsburgh Facility (as defined below). The primary focus of this new plant was the nutraceutical and functional food industries, providing customers with natural solvent-free products that could potentially meet organic market requirements. Thar expects to transition the majority of the plant’s utilization to the cannabis industry.

  • 2014

    Thar’s toll processing plant received kosher and halal certifications for the extraction and purification of astaxanthin, an ingredient for nutraceutical products. Thar expanded its toll processing plant so as to create the largest algae extraction plant in the United States used for the production of astaxanthin.

  • 2015

    Thar’s toll processing plant received GMP certification with respect to the production of astaxanthin.

  • 2017

    Dr. Chordia is awarded the EY Entrepreneur of the Year award for Western Pennsylvania and West Virginia with respect to his entrepreneurship and role at Thar. Thar expanded its purification offerings to include supplying process-scale low, medium and high-performance liquid chromatography equipment and related services.

  • 2017

    Thar further expanded its purification offerings to include supplying process-scale supercritical fluid chromatography equipment and related services. Thar manufactured and delivered one of the largest high-performance liquid chromatography plants ever made, having a 600 millimetre internal diameter DAC column, in the United States. Thar Extract enters into its first joint venture with Plant Science with respect to the NY Joint Venture for toll processing.
