The project "Municipal Knowledge Transfer Maghreb-Germany" between the German waste management company of the district of Böblingen and the Tunisian municipality of El Guettar is part of the CoMun program and strengthens the cities as key players in national, regional, and local development. Furthermore, it reinforces their capacities, structures, and urban services through exchanges among cities in the Maghreb region.

The project consists of several key objectives: Raising awareness of the population for waste separation, construction of a recycling centre, promoting awareness for biodiversity and circular economy through a pilot project on in-house composting and construction of a composting station which started in 2020.

The municipality of El Guettar is an oasis settlement with approximately 20,000 inhabitants and is located in the centre of Tunisia. Moreover, it is an important green lung for the local population. Therefore, environmental protection is a central issue for the community.
