A call to address business challenges from the field of Circular Economy. From PATIO Campus, an association founded by BMW Group España, Cepsa, Iberia, Inditex, L’Oréal, Mahou San Miguel, Merlin Properties and Pascual, we call on the entrepreneurial ecosystem to present us with solutions and ideas that address the following challenges:


Waste management and recovery

Sustainable water management

Sustainable water management is crucial to minimize the water footprint and ensure efficient use of this vital resource. We are looking for innovative technologies and methods that facilitate water management, facing increasing regulations and expectations of sustainability.


Circular value chain

Integrating circular economy principles throughout the value chain represents a significant challenge. We need solutions that improve traceability and transparency in the use of recycled and sustainable materials, facilitating collaboration between suppliers and partners and promoting sustainable practices at every stage of the production process.


Zero Emissions

The energy transition is an urgent priority to meet global sustainability decarbonization objectives. Companies need innovations that help them implement new processes towards sustainable models and promote innovative solutions for the management of their emissions.
