Re-Claim is a Danish material innovation company developing circular building materials from residual bark generated by the timber industry. Today, more than 90% of bark produced at sawmills is treated as waste and burned as low-value biomass. Re-Claim works to change this by transforming bark into high-value architectural materials that can be used in construction.

The company has developed a method for pressing bark into durable panels using a bio-based binder derived from natural wood resin and grey water. This process allows the natural properties of bark, its closed cell structure, UV resistance, durability and distinctive color, to be translated into façade cladding and architectural surfaces.

Re-Claim’s primary focus is the development of exterior façade cladding panels designed to function as a circular and biogenic alternative to conventional façade materials such as aluminum, brick and composite panels. By utilizing an existing sidestream from the timber industry, the material contributes to extending the lifecycle of wood resources while reducing the need for energy-intensive materials.

The company collaborates with architects, developers, engineers and sawmills to bring the material from prototype to scalable construction applications. Through pilot projects and material testing, Re-Claim is working to document the product’s performance, fire classification, durability and environmental impact.

Re-Claim’s ambition is to introduce bark as a new category of building material within the construction industry, one that combines architectural quality with resource efficiency and circular material flows. By turning an overlooked natural resource into a valuable building component, the company aims to contribute to a more regenerative and climate-conscious building sector.
