A method for production of cores for doors, partitions, furniture and the like. A filling material is mixed with a binding agent and the core is form-pressed in a desired shape, preferably as a plate-shaped item, where biomass is used as filling material, for instance, in the form of straw and stalks. A binding agent is used, mainly consisting of either UF-glue (urea-formaldehyde) or MUF-glue (melamin urea-formaldehyde). Preferably, the core further contains a foaming agent. A core may be provided as a form-pressed, mainly plate-shaped item, where the filling material consists of biomass, for instance, in the form of disintegrated straw and stalks, and where the binding agent mainly consists of UF-glue or MUF-glue, to which a foaming agent preferably is added.
