|Title:||PROCESS FOR RECYCLING PRODUCTS HAVING COMPOSITE MATERIALS, COMPOUNDS OR RESINS CONTAINING ABSORBENT POLYMERS|
The used absorbent products, such as diapers and sanitary napkins, containing cellulose pulp and other polymers, are submitted to the steps of: immersion in a solution with controlled pH range and radiation for sterilization of the products; crushing; washing with the use of washing liquid under agitation to separate the cellulose pulp from the other materials of the absorbent products; and forced drying/dehydration. According to the process, the different materials resulting from the drying step can be further submitted to the steps of: mixing homogeneously and in the necessary proportions, the different materials resulting from the drying step; melting in a new blend or composite material; processing the blend or composite material into granules; and molding the granules in final products/test bodies.
