In general, the explosive growth of the population, high industrial development, pollution of the environment and changes in the climate of the earth are becoming increasingly wasteful. In particular, in the case of a tree which is a raw material of paper, the poverty phenomenon is prominent, and the poverty of the tree has a great influence on air pollution as well as environmental pollution.

In order to prevent the above-mentioned trees from being tainted, countries around the world are making efforts to develop technologies that can recycle and use waste coated paper. As one of the prior arts, vinyl and paper fiber separation technology of waste coating paper currently used is continuously supplied from the pretreatment process, and the paper fiber and vinyl (PVC, etc.) are separated and sorted by blowing and attached to the vinyl by washing water. The technique of dropping the papermaking fiber down is used.

However, the conventional technique as described above separates and sorts the papermaking fibers attached to the vinyl through the wash water, causing excessive wastewater to contaminate the water quality. Therefore, there is a problem in that it requires a subsidiary facility such as a wastewater treatment facility for purifying the generated wastewater.
