Not just bullshit and complex material, but with a concrete perspective for action. In a series of podcast programmes, Meet-ups with knowledge and inspiration sessions and challenges, Het Nieuwe Nassen offers Rotterdam hospitality entrepreneurs practical tools to get started right away. Het Nieuwe Nassen has grown into a local movement of Rotterdam restaurants, food entrepreneurs, nature-inclusive farmers and sector organizations that together put the food transition on the map.

Circular Challenge
The Circular Challenge is an intensive six-week process in which multidisciplinary teams of young professionals convert a concrete residual flow into a circular product that is economically viable and scalable. During the festive finale, the teams will present a working prototype in addition to the business case. After this, BlueCity offers tailor-made guidance: within BlueCity to an independent startup or within the organization in question as a corporate startup.

Hackathons
To make the circular economy a reality, a lot of hacking can still be done in our current social system. Enter: the BlueCity Hackathons. In these three-month programs, pioneers work on a specific problem. At the end of the day, they present a concrete solution, from a prototype to a change in the law.
