The Chemours Company announced that Joseph Martinko, President of Thermal & Specialized Solutions, has been awarded the 2025 Winthrop-Sears Medal by The Chemists’ Club. The recognition highlights his team’s role in advancing sustainable thermal management technologies through the commercialization of Opteon low global warming potential (GWP) refrigerants.
The Chemists’ Club noted that Martinko and his team have demonstrated vision, innovation, and entrepreneurial contributions in developing refrigerants and solutions used across multiple industries. “Joe and his team have been instrumental in positioning Chemours as a global leader in sustainable refrigerants and thermal management solutions,” said Dr. Roland Stefandl, president of The Chemists’ Club.
Martinko has more than 30 years of experience in the chemical industry, including over 20 years in Chemours’ former fluoroproduct business. Under his leadership, the Opteon portfolio has been expanded with low GWP refrigerants and thermal solutions applied in air conditioners, heat pumps, food storage, medical devices, data centers, and transportation.
The award will be presented during The Chemists’ Club’s annual Egg Nog Dinner on December 11 at the New York Players Club. The Winthrop-Sears Medal, established in 1970, is given annually to individuals whose achievements have significantly contributed to the chemical industry and society.
“I’m honored to receive this recognition from The Chemists’ Club on behalf of the entire Opteon team,” said Martinko. “At Chemours, we believe in putting our customers first, working together as one team, and doing what’s right for people and the planet.”
