The JC ECOMET Group is an international Greentech company with headquarters in Lucerne / Switzerland and Hamburg / Germany. It was created as a joint venture by experienced companies that have long focused on sustainability and responsible business practices in their respective areas.

JC ECOMET has developed a disruptive concept to use efficient plasma furnaces to produce high-quality metals and alloys on environmentally friendly and from today’s raw materials of civilization. In the spirit of the circular economy, the company uses used metals for their recovery and refinement.

Metals and rare earths are available in the form of electronic waste such as smartphones, packaging waste such as espresso capsules or components such as catalysts and batteries in much higher quantities than a few years ago. The recycling of such metals by ECOMET technology is real recycling, with the side effect that it produces 98 percent less CO2, does not use any water and about 50 percent less energy than traditional metal production.

The first production site is located in Finland, the global pioneer in circular economy. Further locations in Europe as well as Central and North America are under development.
