The Caverne d'Ali Baba (Ali Baba thieve's cave) is an initiative by and for students in the art school of ESA Saint-Luc, in Brussels.

According to the Fédération des Récupérathèques, of which the initiative belongs to, the service stands as a shared and co-managed warehouse of reuse materials, available to students for any of their creative projects. Valorisation and exchanges make use of local virtual currency. These initiatives aim at promoting a sustainable model in schools, based on collective intelligence, solidarity and social interaction.

In Ghent, Belgium, the circular economy brings together companies, institutions, governments and citizens on the way to sustainability. The Old Dockyards is a waterfront housing project where closing loops at the district level is key. Approximately 1,500 housing units will be constructed through public-private partnerships (PPPs).

Water2REturn is an Innovation Action co-funded by the European Commission under its Horizon 2020 (H2020) programme.

London is among one the world’s most cosmopolitan and oldest cities, with a history spanning nearly two millennia, and one of the most cosmopolitan. As Britain’s largest city and country’s economic, transportation and cultural capital, over 8 million people live in London. The city is growing fast and its population is predicted to reach over 11 million by 2050. A more flexible and sustainable approach to products, housing, office space and critical infrastructure is crucial to London’s ability to adapt and grow.

Like many cities, Ljubljana is faced with significant overgrowth of Japanese knotweed, a plant on the list of 100 most invasive non-native species worldwide. Ljubljana teamed up with the Re-generacija collective of young designers and architects focused on issues connected to social and environmental well-being, as well as the University Botanic Gardens Ljubljana, the Pulp and Paper Institute and the public waste management company, Snaga, to prevent excessive overgrowth of the plant and reuse it.
