Abstract
The invention relates to a method for separating waste polyurethane foams, wherein for each polyurethane sample () of a supply stream () comprising polyurethane samples () from waste at least one respective spectrum () is recorded, wherein the at least one respective spectrum () is recorded by near-infrared spectroscopy, wherein each polyurethane sample () of the supply stream () is classified by a classification algorithm (), which classification algorithm () is based on machine learning, based on the respective at least one spectrum () into a respective class (-) of at least two classes (-), wherein the supply stream () comprising polyurethane samples () is separated into at least two streams (-) according to the classification into the respective class (-) and wherein each class (-) corresponds to a type of polyurethane. The invention also relates to a system for separating waste polyurethane foams.
