Circular economy, the new concept for attaining sustainable consumption and production, will not be implemented without multisectoral and international cooperation. INNOWO, Circular Change, INCIEN Czechia, and INCIEN Slovakia are launching the International Circular Week this year to promote circular economy across countries. This International Circular Week will take place from 7 to 13 October 2019, and aims to engage all circular stakeholders in central Europe and beyond.
