Title: METHOD FOR RECOVERING AND PRODUCING PLASTICS CONTAINED IN SANITARY PADS AND DIAPERS
Abstract:
The present invention patent relates to a method for recovering and producing plastics contained in sanitary pads and diapers, belonging to the chemical sector, more particularly relating to sanitary pads and diapers for personal use, producing PE (polyethylene) and PP (polypropylene) pellets, with the aim of re-using the material discarded during the production of sanitary pads and diapers, since the industrial applicability of PE and PP in the production of sanitary pads and diapers is extremely important and their cost extremely high, requiring a strict control, any losses in the production system caused by the high speed of the machines, as well as processing losses, being considered high losses for the industry. The present invention patent relates to a continuous and closed-loop process for recovering and producing plastics contained in sanitary pads and diapers, comprising the following steps: a) feeding the system; b) grinding in a cutting mill; c) agglutinating; d) extruding (the plastics); e) conveying the pellets; and f) centrifuging.
