Brick construction creates lasting materials but often ends in waste when buildings are torn down early. Engineers in Austria built reusable brick walls that can be dismantled and rebuilt, cutting emissions and debris while suggesting a different future for buildings. Construction sites often begin with new materials and end with massive piles of waste. Across the world, buildings are demolished long before the materials inside them wear out. Brick walls that could last for generations are frequently crushed and discarded after only a few decades of use. Researchers at Graz University of Technology believe that cycle needs to change. Working with Austrian brick producer wienerberger, the team has developed reusable brick wall systems designed to survive beyond the life of a single building. Instead of binding bricks together permanently with mortar, the researchers created industrially prefabricated wall elements connected through reversible joints. The walls can later be dismantled without destroying the materials, then rebuilt at another site. The project, called Re-Use Ziegelwand, could help reduce greenhouse gas emissions and construction waste while giving buildings a …
