Title
(EN) METHOD FOR RECYCLING COMPOSITE MATERIAL
(PT) MÉTODO PARA RECICLAGEM DE MATERIAL COMPÓSITO
Abstract
(EN)
The method for recycling composite material comprising cellulose, plastics material, aluminium and water and obtained by a pulping process, comprises the phases of: - introducing the material into a tank full of water to allow settling of heavy foreign bodies and separation of the residual solid fraction, - contrifuging the residual solid fraction, so as to reduce its moisture content, - shredding and drying the solid fraction, so as to obtain a dried material having a water content of less than 2% and a cellulose content of less than 2%, - compacting the dried material, and - extruding the compacted material and subdividing it into granules.
