• BENTU Design 3D Prints Street Furniture From Demolished Urban Village Waste March 17
Additional Context
Chinese design studio BENTU Design has developed a method for turning construction rubble from demolished urban villages into 3D printed public furniture, with the resulting material containing up to 85% recycled solid waste. The project, called Inorganic Growth, has produced two pieces so far: a chair called PU and a stool called YOU, both fabricated from crushed concrete, brick rubble, and mortar.
The material preparation process is technically demanding. Demolition debris gets processed through a jaw crusher for primary crushing, then through an impact crusher for secondary shaping. Multi-layer vibrating screening separates aggregates by particle size. The fine powder fraction, which makes up roughly 30 to 35% of the waste stream, undergoes mechanical and chemical activation before bei
