Particle boards from paper recycling for the production of furniture and other accessories. The invention relates to a process for recycling paper to produce furniture and thereby reducing human pressure on forests. The panels are, in fact, a component of paper (1) and cardboard (2) crushed after wetting to which yarns (3) cut into thin strips are added, thus forming a homogeneous substrate. This substrate is added to various types of binder (Hot Glue Off (4), Top Bond Glue (5), Starch paste (6), Gypsium (7) previously prepared to consolidate the ground paper. The dosage is done in 80% of ground material and 20% of binder. The 20% of binder is divided as follows: Starch paste (6) 10%, Slaked lime glue (4) 5%, Top bond glue (5) 2% and Gypsium (7) 3%. After mixing the substrate (1 + 2 + 3) and composite solution (4 + 5 + 6 + 7) of binder at the temperature of 100 ° C, a homogeneous paste is obtained, subject to cooling. This dough is then pressed in a mold using a multi-axis presser at a pressure of between 5 and 10 tonnes for 10 to 20 minutes then demolded, dried. The dimensions of the panels depend on that of the molds used. The particle panels (Fig. 1) easily obtained be sawn, sanded, vice or nailed and able to support existing coating forms. The panels are in this case coated with formicas (8). The method according to the invention is intended to provide an alternative to wood by producing furniture from recycled paper.
