Kemira, a global leader in sustainable chemical solutions for water-intensive industries, with its global innovation center onsite at EriCa Green Chemistry Park, is the lead industry partner for EriCa Reactor and its first program cohorts.
Aligned with Kemira’s strategy and the UN Sustainable Development Goals, EriCa Reactor focuses on solutions that accelerate decarbonization, enable circularity, and secure clean water, ensuring prosperity for both people and the planet.
Startups bring agility and fresh ideas. Kemira brings scale, industry insight and R&D expertise. Together, solutions can reach markets faster.
According to the UN and WHO, lack of safe water impacts over two billion people worldwide, leading to disease, child mortality, and stunted development. Climate change, population growth, urbanization, and new contaminants like microplastics increase the urgency for new solutions in treatment, scarcity management, and responsible water use.
Kemira, a global leader in water treatment and sustainable chemical solutions, seeks to explore breakthrough solutions and help promising companies scale globally, leveraging Kemira’s long experience and deep expertise in water-intensive processes.
Startups, scaleups, and spinoffs developing clean water solutions are invited to apply. Examples include new technologies and chemical solutions in water treatment and purification, or digital tools such as AI and IoT for sustainable water management. The program welcomes a wide range of approaches from around the world.

Climate change and resource depletion are forcing industries to rethink how materials are sourced and used. Enabling circularity and replacing fossil-based raw materials are essential to reduce emissions, secure long-term resilience, and meet growing regulatory and market pressures. Enabling circularity should go far beyond recycling. It requires fundamental changes to the way materials are sourced and how products are designed, produced, sold, used, and disposed of.
Kemira is committed to enabling a biobased circular economy and adopting best practices across our operations and along our value chains. Examples of potential solutions include new technologies and chemical solutions in raw material refining, material circularity and value creation, or digital tools such as AI and IoT for renewable processes.
