At Clean, we work on various projects that strengthen innovation, water and environmental technology. Below you can see the types of projects we have and read more about each one.

Innovation projects enables small and medium-sized enterprises to drive green transformation by developing, demonstrating, and testing their water and environmental technology in collaboration with other actors such as another company or knowledge partners, making it possible to put technology into practice and drive innovation.

Partner projects are collaborations where Clean works closely with partners to create synergies and solve water and environmental challenges through joint projects and initiatives.

Knowledge bridge projects brings knowledge from knowledge institutions to businesses, where experts advise companies and enable continuous innovation and development, even when the technology is not yet fully mature.
