Abstract
A method of producing a building material uses bast fibers and shives of bast fiber plants as a starting material. The bast fibers and the shives of bast fiber plants are loosened, are metered, and are subsequently fed to an applicator device for liquid additives and/or to a spreading system for solid additives. The bast fibers and the shives of bast fiber plants are subsequently spread in the form of a fleece or a cake.
