Research on green-waste-based construction materials for Brussels was presented at SBE25 in Zurich. The presentation reports regional material-flow and life-cycle work assessing the use of urban green waste in lower-impact construction products. The discussion centres on Urban biowaste, Construction materials, Life-cycle assessment, and Circular economy.

The contribution is developed through Regional material-flow analysis, life-cycle assessment, and construction-material assessment. The geographical or conceptual scope is Brussels-Capital Region, Belgium. It was presented at Sustainable Built Environment Conference 2025, Zurich during 2025.

The contribution reflects the Lab’s interdisciplinary approach, combining quantitative and qualitative evidence to translate urban-metabolism research into planning, design, governance or policy.
