The term “biomaterial” was created as a generic term for materials that are based entirely or mainly on renewable raw materials (natural products or wood). The term "biomaterial" is not regulated by law and the term "bioplastics" is not protected and is therefore not used uniformly.
The proportion of raw materials of biological origin in the final product can fluctuate depending on the production and processing process. A fixed limit of the bio-based component of biomaterials does not exist.
Biomaterials are divided into bioplastics, natural fibre-reinforced plastics (NFK) and WoodPlasticComposites (WPC, wood-plastic composites). In addition to these innovative materials also traditional materials such as chipboard and blockboard (wood materials) are biomaterials.
