Abstract:
1. A process comprising the steps of: a) feeding waste paper into a pulper with water to yield a pulp, the waste paper having a consistency between 15 and 20%, wherein the waste paper comprises ashes between 15% and 40% and cellulosic fibers between 60% and 85%; b) diluting with recycled water the pulp obtained from step a) until a consistency between 5 and 10% is achieved; c) enzymatically treating the diluted pulp obtained from step b); d) adding one or more inorganic salts and one or more glues to the enzymatically treated diluted pulp obtained from step c) to determine variability in mechanical properties of a final material of the process, wherein the one or more glues comprise at least one of resin acids, salts thereof, and esters thereof; e) diluting with water material obtained from step d) until a consistency between 1 and 3% is achieved; f) filtering material obtained from step e) by vacuum and optional press; g) drying material obtained from step f); wherein there is a feedback of residual water suspension after step f) into containers where steps b) and e) take place; and wherein any residues resulting from the process are reused in the process itself.
