Working group "Digital Waste Technology"

The working group "Digital Waste Technology" is concerned with research into sensor-based sorting and material flow analysis and their efficient use in waste management for the classification and separation of waste material as well as process digitalization in the sense of an efficient circular economy.

Sensor-based sorting enables non-contact and imaging detection of optical and spectral solid properties as the basis for application-specific object classification and separation. Sensor-based sorters are complex mechatronic systems. The development and use of sensor-based sorting therefore requires interdisciplinary knowledge, from the fields of solid-state spectroscopy, sensor technology, mechanical engineering, control engineering, image data processing and process engineering.

Sensor-based sorters already perform a variety of functions in waste processing.  They will also play a key role in solving new challenges associated with increased value-based recycling and digitalization in waste processing.

The working group "Digital Waste Technology" and the chair have dedicated themselves to this research and teaching task.

The Chair of Waste Processing Technology and Waste Management (AVAW) has extensive analytical equipment for raw material and sample analysis and has a compact sensor-based test system available for application and contract research projects. It is designed as a two-way chute machine with pneumatic separating device. A particle size range from 3 to 200 mm can be processed. The test system is equipped with three industrial sensors (NIR spectral imaging sensor, high-resolution RBG line sensor with incident/transmitted light mode and induction sensor).

This enables the sorting of a wide range of secondary raw materials, such as waste glass, paper and cardboard, plastic flakes, light packaging, electronic scrap, construction waste, compost and waste wood. By means of sensor fusion, the test system offers the possibility to combine flexibly several sensors in order to solve even very complex or new research tasks.

In addition, a large-scale pilot plant with integrated belt sorter will be available from May 2022 in the Institute's own "Digital Waste Research Lab" in St. Michael. This is equipped with extended multi-sensor technology and can be operated in combination with other processing units. In particular, this enables cycle simulation and material flow analyses in connection with research focuses in the field of process digitization.
