Five Delft architecture students have developed innovative circular construction methods to promote sustainability:

• Larissa Götze revived the ancient rammed earth technique, using excavated soil to create prefabricated, low-CO2 walls.
• Frank Vahstal explored topping up apartment buildings with biobased materials like hemp and straw to reduce climate impact.
• Preksha Rautela designed a circular chain for neodymium magnets, ensuring efficient recycling.
• Elena Grimbacher proposed circular systems for post-war neighbourhoods, integrating water, energy, and food solutions.
• Lara Neuhaus developed rainproof façade panels from walnut shells, using food waste to create sustainable building materials.

These projects highlight scalable, eco-friendly construction solutions.
