Material made of agricultural residual biomass and a core of mycelium composite, coated with exemplary bio-based resins and a transparent topcoat, contributing to ensure the high quality of their technical performances as well as their long-lasting durability. The coating is 90% bio-based, replacing traditional industrial pigments with low-value biomasses, such as corn crops, rice straw, spent coffee grounds, discarded algae and clam shells. It is designed as modular elements for the creation of indoor resilient flooring solutions.
