The Department of Waste Management and Material Flow of the University of Rostock has been active in Arab countries for over 20 years, and has initiated, carried out and scientifically supervised numerous projects. Waste management and material flow is an important theme in the field of German development cooperation in the MENA regions and has gained in significance in recent years.
The current set of issues and suggestions for improvement are the optimisation of waste collection and the introduction of appropriate treatment concepts, for example, but notlimited to, the automatized biological treatment of residual waste. In the Arab regionthe trend is moving away from the production of compost from mixed waste collectionand towards the production of substitute fuels for the cement industry. In Jordan,Tunisia and Egypt appropriate MBA-projects are planned. In these regions only simpleMBA-concepts with treatment costs of circa 25 to 30 EUR/Mg can be implemented.Waste to Energy is an appropriate concept for the Gulf States. The necessary technicaland financial framework must be clarified. The sustainability of the projects, which will be financed by international donors, is a current theme and can only be achieved through the integration of local infrastructure, such as universities, vocational training centres, local engineering firms and waste disposal contractors.

Verbrennungsrückstände – Herkunft und neue Nutzungsstrategien
© Veranstaltergemeinschaft Bilitewski-Faulstich-Urban (3/2010)
Die Nutzung von Verbrennungsrückständen wird bei Holzaschen seit Generationen praktiziert. Auch für die Rückstände aus der Abfallverbrennung ist diese Idee nicht neu. Frühere Entwicklungen zur Behandlung von MVA-Rückständen zielten zunächst darauf ab, von diesen Substanzen ausgehende Umweltbeeinträchtigungen weitestgehend zu vermindern. Nimmt man aber eine Inertisierung von Verbrennungsrückständen beispielsweise durch reduzierendes Schmelzen vor [Faulstich 1992], so sind damit auch eine verbesserte Stofftrennung und in der Folge erweiterte Nutzungsmöglichkeiten für die abgetrennten Stoffströme verbunden.

Optimierte Konzepte zur Klärschlammtrocknung bieten hohe Energieeinsparpotentiale und einen flexibel einsetzbaren Ersatzbrennstoff
Development of local municipal solid waste management in the Western Transdanubia region of Hungary

Hungarian municipal solid wastes (MSW) management has developed tremendously over the past 15 years. More than 3,000 landfills and dumps had been closed, just to mention one improvement. However, still, lots of work is necessary to accomplish the EU’s ambitious aim of decreasing landfilling and increasing recycling and composting.
Environmental-economic impact assessment of business models in the Austrian waste economy

The dynamic macroeconomic one-region and multi-sector model WIFO.DYNK (dynamic new-Keynesian) was adapted to model the employment and value-added impacts of the Austrian waste economy in this respect. It is based on the most recent input-output tables of Statistics Austria.
The circular packaging design guideline and holistic sustainability assessment in circular economy
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
The FH Campus Wien Circular Packaging Design Guideline provide recommendations for circular design for the whole supply chain. Circular design is a necessary prerequisite to achieve the goals of the European Circular Economy Package which requires full recyclability of packaging by 2030. Circular packaging should re-duce resource consumption and environmental impacts of packaging. The assessment of packaging sustainability requires the calculation of direct and indirect environmental impacts and circularity at the same time. A method for holistic sustainability assessment of packaging has been proposed by FH Campus Wien and developed in an ECR-working group (Efficient Consumer Response) with the participation of a number of companies along the whole supply chain (brand owners, retailers, packaging manufacturers and packaging systems).
