Tech4Regen field visit: meet CompPair, Windworks & Sunaxer
Join us for an exclusive tour at the forefront of startup labs industrializing next-generation materials and energy solutions for the circular economy.
On April 23, three startups from the Tech4Regen accelerator program—Windworks, CompPair, and Sunaxer —will host visits to their labs at Ateliers de Renens. This unique event offers participants the opportunity to explore real prototypes and industrialization processes, see technologies in action, and engage directly with disruptive startup teams.
CompPair develops repairable composite materials, enabling damaged high-performance components—such as those used in sports equipment, mobility, or energy—to be easily repaired rather than replaced. Their technology helps extend product lifetimes and reduce waste in industries that traditionally rely on difficult-to-recycle materials.
Windworks focuses on small-scale wind energy solutions, designing and building wind turbines adapted to local and decentralized use. Their approach aims to make wind power more accessible, modular, and suitable for urban or off-grid environments.
Sunaxer was created to accelerate the decarbonization of industrial heat. It accelerates the adoption of solar process heat through its innovative receivers for concentrating solar collectors.
