Reuse systems and reuse methods

Abstract

To provide a recycling system and a recycling method that are able to evaluate the cushioning properties of a cushioning material.SOLUTION: An arithmetic processing system 100 for cushioning-material recycling, as a recycling system, includes: a cushioning- material thickness evaluation device 11 to which a measurement result of a thickness of a cushioning material is input; an evaluation module 17 that calculates remaining cushioning properties, which is a remaining degree of cushioning properties of the cushioning material, based on the input thickness of the cushioning material; and an arithmetic processing device 4 that, based on the calculated remaining cushioning properties, determines whether to recycle the used cushioning material or not.SELECTED DRAWING: Figure 1

Claims
