Lena Fritsch presenting her semester project Graded Biofoam Systems for Responsive Architectural Assemblies at die Angewandte for the Circular Strategies Symposium 6: Cultivating Matter. Is the future alive? - This project explores biofoam as a circular, responsive material system that is co-formed, biodegradable, and derived from accessible ingredients. Conventional PU-foam is a closed-end material:once used, it becomes waste. The biofoam developed here uses a simple, low-tech recipe based on gelatin, glycerin, and water. The resulting foam is castable, and its stiffness and texture can be tuned through proportion changes. Unlike PU, this foam is compostable, remeltable, and recyclable within its own system, enabling a regenerative material loop.
