摘要

Process of recovery of organic matter in the treatment of urban solid waste and the necessary system for this purpose. Procedure of recovery of organic matter of urban solid waste (rsu) that makes it possible to increase the percentage and quality of the recovered organic matter (mor) in plants of biological mechanical treatment (tmb). Said method is characterized by including at least the following steps: a granulometric separation by means of a drum screen, a separation of organic matter by means of optics, a conditioning of the organic matter recovered by a crushing-separation process by means of a hammer mill. This process can be completed with the following additional stages: magnetic separation, vibrating screen, sand trap, sand washing and/or hydrocyclone. The system comprises at least one optical separator of organic matter and a hammer crusher being able to have a drum screen, a magnetic separator and a vibrating screen. An organic material of higher quality is obtained, the material destined for the final elimination is reduced and the efficiency of the anaerobic digestion and/or any gold process of later valorization is improved.
