ABSTRACT:
A building material includes shives, previously considered to be a waste material. Shives of bast fibers are added to bast fibers and a binder. The shives may contain fibers which are still partially attached to the shives with their natural bond. These partially attached fibers project laterally from the shives in an irregular fashion and are between 2 mm and 100 mm long. The shives and the loose fibers and/or the shives with the partially attached fibers are fed into a coating device for liquid additives and/or into a spreading system for solid additives, and subsequently form a fleece or cake. An air flow may be used for performing a mechanical felting of the fleece. A method and an apparatus for producing the building material are also provided.
