Reedboards are sustainable particleboards made from common reed and bound with cellulose, ideal for environmentally conscious consumers and designers who care about the Baltic Sea. Harvesting reed aids in restoring the Baltic Sea's coastal ecosystem and biodiversity. Reedboards are 100% biodegradable, free from harmful chemicals, and crafted from a highly abundant local resource. By transforming an invasive plant into a valuable resource, Reedboards promote a circular bioeconomy and reduce the carbon footprint, turning an environmental challenge into an opportunity.
