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.

Until now, the data on CRMs has been produced by a variety of actors and lies scattered in different databases, formats and reports which makes it difficult to compare or aggregate. The ProSUM project - Latin for ‘I am useful’ - aims at producing the EU Urban Mine Knowledge Data Platform (EU-UMKDP) providing user friendly, seamless access to data and intelligence on mineral resources from extraction to end of life products. The project will be addressed to a wide range of end-users, including the recycling industry, producers and producer compliance schemes, and policy makers.
