Roxia Oy separates its environmental technology business into a new company: Roxia Plasma Oy

Lappeenranta, Finland – 27.3.2024


Roxia Oy separates its environmental technology business into a separate company called Roxia Plasma Oy. The new company was created by combining Roxia’s environmental technology business with Wapulec, a company specializing in cold plasma technology. In addition, the Vartiainen family’s investment company Capillary Oy and the North Savo Startup Fund have become owners.

Roxia Plasma Oy focuses on the development and commercialization of cold plasma oxidation technology. This innovative technology offers an effective solution for the removal of harmful ingredients from wastewater, and it is particularly suitable e.g. for the removal of pharmaceutical residues from the pharmaceutical industry and municipality wastewaters. In addition, the technology has proven to be a promising alternative in the removal of forever chemicals such as PFAS compounds.

“The founding of Roxia Plasma Oy reflects our commitment to the development of environmental technology and a sustainable future,” says Timo Vartiainen, chairman of the board &CEO of Roxia Oy. “We are proud to offer an innovative solution to help solve major environmental problems in the world.”

“The investment in Roxia Plasma Oy supports our vision to invest in innovations with high growth potential and offer value to our investors. We strongly believe that this investment responds to growing environmental challenges and opens up new opportunities in the growing global market. In particular, the startup’s know-how and ability to process harmful compounds from wastewater makes it a significant addition to our portfolio.” says Nora Tuikka, CEO of Nostetta Ventures.

With the establishment of Plasma Oy, Roxia Oy focuses even more on the solid-liquid separation and related after-sales service. Roxia Automation Oy continues as a subsidiary specializing in industrial automation.
