METHOD FOR PURIFYING A CONTAMINATED SOLVENT AND CONCURRENTLY PRODUCING A SEMI-FINISHED PRODUCT FOR USE IN THE PRODUCTION OF PANELS

摘要

The invention relates to a method for purifying a contaminated solvent and concurrently producing a semi-finished product for use in the production of panels. The inventive method is characterized in that it comprises following steps: a) providing a first mass of fibrous material; b) softening at least part of a second mass of plastic material by impregnating it with a contaminated solvent adapted to at least partially dissolve said plastic material; c) mixing said fibrous material with the mass of softened plastic material to produce a compound; d) pressing said compound at a temperature that is at least equal to the melting temperature of said plastic material to obtain a semi-finished panel and a fraction of evaporated solvent.
