Thanks to the permanently increasing potentials of data processing, the fields of application and the breadth of application of near-infrared technology in the waste industry have continued to expand. The application of near-infrared technology for real-time quality assurance for substitute fuels is relatively new. In contrast to the established (offline) laboratory analytics, this facilitates a direct impact on the quality in the process. A system developed by TOMRA Sorting GmbH is being further developed within the framework of joint research in the IWARU at the University of Applied Sciences, Muenster. The potential applications of the system are determined by various underlying conditions. Thus, a representative measurement is only guaranteed after a certain minimum quantity has been processed. Here, the material flow is represented by the substance groups entered in the system. At the same time, black or relatively small particles cannot be identified by means of near-infrared technology. The comparatively shallow penetration depth of the near-infrared radiation into the material surface also has a great impact on the accuracy of the analysis. As a result, e.g. inaccuracies in the measurement of the water content and in the determination of the substance groups in composite material can arise. This and other underlying conditions highlight the ongoing need for research.
