Advanced Waste-Splitting by Sensor Based Sorting on the Example of the MT-Plant Oberlaa

Waste management is playing a significant role in efforts to combat the anthropogenic climate change and environmental pollution and is therefore continuously changing from land filling to other options, such as material reuse and recycling all over the world. If waste will be used as a substitution for primary resources, it has to be processed to meet the required material or quality criteria. Sensor-based sorting is a state-of-the-art technology for the treatment of separately collected recyclables, such as plastic, paper and glass, in order to secure the compliance with given quality standards.

Heterogeneous wastes, which cannot be material-recycled easily are used forenergetic 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.

Combining laser cleaning and LIBS: fast and precise recycling of metal alloys
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
In respect of a limited amount of raw material, costs, CO2 and waste reduction, high precision metal recycling is getting more and more important these days. Contaminations of the melt with unwanted or outright detrimental elements (e.g. C, S, P, Cu or Pb in steel, Cr or Ni in low-alloy steels, Li in aluminium and so forth) are a huge liability toward the ‘‘alloy-to-alloy’’ recycling goal and essentially the only option in this case, is either costly dilution with clean raw materials, downgrading or worst case scenario discarding.

Reporting of food waste in the EU – Results of current estimates in Germany
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
In February 2019, the German Federal Cabinet adopted the 'National Strategy for Reducing Food Waste', setting a framework for the future direction of this initiative. Among other things, it stipulated that an inter-ministerial "Indicator 12.3 Working Group" should prepare the data bases and methods for nationwide balancing of food waste generation (baseline). Based on existing 2015 data, this status quo analysis will be used as a starting point to agree on milestones for the respective sectors.

Anforderungen an den emissionsarmen Betrieb von Kompostanlagen im Hinblick auf das BVT-Dokument
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Im Rahmen eines Projektes des Umweltbundesamtes mit der Stadt Wien wurden unter Einbindung von Stakeholdern und Anlagenbetreibern wesentliche Anforderungen an einen emissionsarmen Betrieb von großen Kompostierungsanlagen formuliert. Diese Anforderungen wurden unter Berücksichtigung der Richtlinie zum Stand der Technik der Kompostierung und auf Basis von Best-Practice-Beispielen österreichischer Kompostierungsanlagen zusammengestellt.

Klimaschutzkonzept+ Energieautarke Deponiegasbehandlung mit Wärmenutzung und Eigenstromversorgung am Beispiel der Deponie Bengelbruck
© Universität Stuttgart - ISWA (3/2016)
Auf der Deponie Bengelbruck wurden seit der Inbetriebnahme im Jahr 1972 ca. 1.230.000 m³ Abfälle eingebaut. Bereits ab dem Jahr 1995 wurden keine Bioabfälle (Beginn der Getrenntsammlung) und Klärschlämme mehr abgelagert, so dass das Gasbildungspotenzial deutlich reduziert wurde.

The relevance of the context for greenhouse gas emissions from residual municipal solid waste management
© Wasteconsult International (5/2015)
Given the current EU legislation, the assessment of greenhouse gas emissions related to the treatment of residual municipal solid waste is relevant. As to a lack of models that allow for comparing the climate impact of different treatment options (incineration, mechanical biological treatment, landfilling), a model adequate for such comparisons is developed. Due to the impact of background conditions on the climate performance of waste treatment, the model is adaptable to different EU context situations. Exemplary calculations conducted with the developed model reveal, that the context of residual municipal solid waste management is of such importance that it even impacts the order of treatment technologies when assigning them according to increasing climate impact.
