    Abstract:

    Sensor-based technologies, such as sorting, have become state of the art in many branches of solid waste treatment. As solid waste has been recognized as an important deposit of secondary resources economically and politically, sensor-based technologies help to increase the width and depth of solid waste treatment. For example, massive throughputs as well as recovery of residual materials are made possible and feasible. Nevertheless, there are opportunities for innovation to ultimately expand our useable resource basis even further.
    This paper highlights the experimental development of a spectral inductive analyzer to be incorporated into a testing method. The goal of the method is to detect residual metals of low concentration at three levels of increasing complexity: indicative, qualitative and quantitative. A conductive coil at close proximity to a moving material stream is electrically charged with a sinusoidal waveform between 0 and 100 kHz. By crossing this frequency spectrum, different responses are created from different materials and recorded to be analysed. This paper presents initial results that allow for positive conclusions regarding the above mentioned levels of detection. An outlook is given on further developments and goals.
