  • Patent number: 12214391
    Abstract: An absorptive article quick decomposition system and operating method thereof is provided. The absorptive article quick decomposition system is mainly constructed by a cutting separating module, a liquid proof reclaimed material filtering module, a recycling module, a salt slurry processing module, a plastic raw material manufacturing module, a hygroscopic raw material manufacturing module, and a fluff fiber raw material manufacturing module. The absorptive article quick decomposition system and operating method make the recycled absorbent articles become possible to be decomposed into plastic raw materials, hygroscopic raw materials and fluff fiber raw materials. In addition, organic pollutants on absorbent articles are decomposed. The purified and treated water thus recovered and the recycling is realized for good.
