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. Earthstone processes the earth through a series of cleaning, drying, and compressing steps, creating a stable, moldable medium. This medium is then shaped into items such as planters, coasters, lighting fixtures, and even furniture components. Each piece retains the unique texture and color of its source location, giving users a tangible connection to the landscape from which the material originated.

Beyond its visual appeal, Earthstone addresses several environmental challenges. First, it reduces the volume of construction waste, a major contributor to landfill overload. Second, it cuts the demand for virgin raw materials, lowering the carbon footprint associated with mining and manufacturing. Third, the project promotes local sourcing, shortening supply chains and supporting community resilience. The design’s modular nature also encourages repair and reuse, extending product lifespans and further decreasing waste.
Earthstone has this blend of sustainability, innovation, and cultural relevance. By valorizing soil, which is a resource often overlooked, the project reframes how we perceive “waste” and invites a broader conversation about responsible consumption. The objects have found homes in boutique stores, design fairs, and online platforms, where they are marketed as limited‑edition, eco‑conscious accessories. Testimonials frequently mention the calming effect of the natural textures and the pride in supporting a product that actively reduces waste.
Earthstone’s success also inspires other designers to explore material upcycling. The project serves as a case study in design curricula, illustrating how thoughtful material selection and processing can generate both aesthetic value and environmental benefit. Workshops and talks featuring the Earthstone team have been organized at design schools and sustainability conferences, spreading the methodology to a new generation of creators.
Looking ahead, Earthstone plans to expand its material palette, experimenting with other locally sourced by‑products such as recycled glass and reclaimed wood. The studio aims to develop a scalable production model that can be adopted by municipalities and construction firms worldwide, turning urban excavation sites into hubs of creative reuse. Earthstone’s soil‑to‑product journey offers a compelling narrative that blends design beauty with tangible environmental impact. It signals a growing appetite for products that tell a story of sustainability, locality, and thoughtful craftsmanship.
