Big tasks usually require perseverance, persuasiveness and a broad-based and well-coordinated team. This is also the case when it comes to establishing a sustainable circular economy in the construction industry in the northwest metropolitan region. 

On January 17, 2025, as part of the Bremer Altbautage and hanseBau 2025, an intensive exchange between the participants took place in the Bremen exhibition hall. The "bau circle" project is entering its second half and took this opportunity to analyze the tactics used so far, best practice examples and the opportunities for further development for the remaining project term. 

Martin Grocholl, Managing Director of energiekonsens, Nicola Illing, Managing Director of Metropolregion Nordwest, Ute Dechantsreiter, Project Manager, and Andreas Lieberum, as moderator, as well as several colleagues from MPA Bremen were also present.
