Abstract

SE MUESTRA UN PROCESO PARA EL TRATAMIENTO DE PRODUCTOS DE PAPEL SANITARIO ABSORBENTE PARA SEPARAR DICHOS PRODUCTOS EN COMPONENTES DERIVADOS PARA SU RECLICADO O REUTILIZACION. LOS PRODUCTOS DE PAPEL SANITARIO ABSORBENTE INCLUYEN PAÑOS HIGIENICOS DESECHABLES, PRODUCTOS UTILIZADOS EN CASO DE INCONTINENCIA, PRODUCTOS DE HIGIENE FEMENINA, COMPRESAS DE CAMA Y OTROS PRODUCTOS ABSORBENTES Y ADSORBENTES. EL PROCESO COMPRENDE EL PASO DE TRATAR DICHOS PRODUCTOS EN AL MENOS UN BAÑO DE UNA SOLUCION ACUOSA PARA ELIMINAR LA MATERIA SOLUBLE Y/O PARTICULADA DE LOS PRODUCTOS. EL BAÑO SE EJECUTA BAJO CONDICIONES QUE LLEVAN A UNA SEPARACION NO DESTRUCTIVA DE DICHOS PRODUCTOS EN COMPONENTES DERIVADOS. EN REALIZACIONES PREFERIDAS, EL PRODUCTO TRATADO OBTENIDO SE TRATA CON AL MENOS UNA SOLUCION LIMPIADORA ACUOSA Y CON AL MENOS UNA SOLUCION ACUOSA DE AL MENOS UN AGENTE BLANQUEADOR Y AGENTE ANTIMICROBIANO, Y SE RECUPERAN MATERIALES CELULOSOS Y PLASTICOS SEPARADOS. EL PROCESO PERMITE LA RECUPERACION DE PRODUCTOS UTILIZABLES A PARTIR DE PRODUCTOS DE PAPEL SANITARIO ABSORBENTES.
