Earthstone, a Belgian design studio, captured global attention when its “Earthstone” project earned a top prize at the 2025 Seoul Design Award . The concept is simple yet powerful: soil excavated from local construction sites is transformed into functional, aesthetically appealing objects for daily use. By turning what is usually waste into valuable design pieces, Earthstone demonstrates how circular economy principles can be woven into everyday life. The project begins with the careful collection of soil from urban digs, a material that traditionally ends up in landfills. First, it reduces the volume of construction waste, a major contributor to landfill overload.
