Repair & ReuseKielMatch excavated soil through the BodenbörseKeep soil in the economic loop Construction and road works generate large volumes of excavated soil. Kiel’s Bodenbörse connects builders, planners, and disposal firms so fill finds a nearby site instead of long hauls to distant deposits. What changed locally - Launched inside city administration in 2023; opened to third parties in 2024. - By end of 2025 roughly 6,600 tonnes of soil and boulders were successfully matched. Who can use it Developers, planning offices, civil-engineering firms, and waste carriers with surplus or demand, contact via the Zero Waste programme pages. Why it matters Matching soil locally cuts long truck hauls and keeps excavation material useful on nearby sites.
