Abstract

Heterogeneous wastes, which cannot be material-recycled easily are used for energetic utilization. Certain quality criteria need to be met in this context, addressing especially the chlorine content due to the product quality as well as to environmental and safety issues. In regard of current issues in climate policy concerning emission trading, also an increased biogenic content in these waste fractions is desirable. Therefore, experiments with a sensor-based sorting technology at pilot scale as well as large scale have been conducted to analyse the technical feasibility of this technology for its application on heterogeneous wastes to gain products with desired material and quality criteria. The results of pilot scale experiments show that the sensor-based sorting technology is generally technically feasible to gain waste fractions with the required characteristics, if the technology was adjusted to the specific waste stream. Due to restrictions during the large scale experiment a number of further issues need to be addressed in
further experiments to allow for a concluding evaluation of that treatment concept.
