6K has developed a microwave-based plasma process called UniMelt to eliminate "forever chemicals" (PFAS) from various environments. The technology uses extreme heat (6,000 degrees) and reactive radicals to break down PFAS in just two seconds. It can be applied to clean water, firefighting foam, and semiconductor plants. UniMelt's process ensures no emissions or fluorine loss, addressing issues of cost and expandability that have challenged other plasma technologies.
