Excavation material – produced in house and infrastructure construction – is the largest material flow in Switzerland at an annual rate of 40 to 60 million tonnes. A substantial part of it is today deposited.
In her exploration of design approaches to this little-used material, Silvana Emmenegger created a series of stools made or rammed earth. The excavation material – a mixture of clay, gravel and sand – comes from various local building sites. Using a rammed-earth method, the stool becomes a stamp that absorbs the quality of the on-site ground into the object.
The project focuses on SDG 12, “responsible consumption and production”.
