We focus on circular innovations!

Our Circular ClimAccelerator Programme accelerates advanced start-up teams with innovative solutions fostering the circular economy.

The Circular ClimAccelerator offers grants for start-ups combined with a tailor-made accelerator programme with circular focus and climate impact. We connect start-ups with the largest climate-focused community in the world powered by EIT Climate-KIC ClimAccelerator as well as investors, partner cities, corporates and ecosystem partners.

The programme will be run virtually, free of charge, and in English.

We are looking for innovations that integrate circularity approaches and footprint indicators: (e.g. water usage, land use, biodiversity loss, chemical pollution, energy demand, CO2 emissions, among others), to reduce the pressure on the Earth’s biophysical limits and promote a circular socio-economic transformation.

Thematic Areas

Circular Construction
Renewable Energies
Construction Material
Waste Management
Mobility & Logistics

Beyond these thematic pillars we are welcoming additional circular innovations in any other relevant area for circualr transformation within cities and the built environment.

Changing the linear production system through technologies that are aligned with circular practices, such as modularity, upgradability and prolonged use are currently helping industries to benefit from new services associated with the value retention of product components and materials.
