Machinery for preparing different qualities of RDF

The present situation in waste management in the European Union shows dynamic development of waste treatment technology. To accomplish the European Waste Directive waste treatment is essential for enhancing recycling and recovery and reducing disposal. The work was performed by means of visits to RDF plants, interviews of operating personal followed by calculations of mass balances and economical indices. Three
types of RDF were defined according their qualities, “RDF light”, “RDF classic” and “RDF premium”. Each type was defined by summarizing three applications. A design recommendation for a ballistic-separator dominated RDF plant is given. Due to the reduced and different machinery this plant shows advantages related to a wind-sifter dominated plant. The differences in energy demand run up to -27%, in investment -23% and in operating costs -22%. Meanwhile two new RDF plants are built in Hagenbrunn, Lower Austria, A, and in Bernburg, Saxony, D, according the proposed technology.

In the course of implementing the circular economy package of the European Union, the Waste Framework Directive was amended recently. Textiles are no longer the poor relation of waste management but have come to the fore.

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.

Tex2Mat: The recycling of towels and laundry made from PET and cotton

The project “Tex2Mat” was a cooperation between companies working in the field of recycling or textiles and universities specializing in the field of polymer engineering and recycling. There were two polymers (PET and PA) examined and the whole project divided into two subprojects.

State-of-the-art and future perspectives in textile recycling
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
Today, the blending of materials within textiles is an asset in the design of protective clothing and various technical applications, but material mixes and blends also found their way into retail trade. The rise in end-of-life items is thus putting pressure on waste management to develop suitable recycling processes. Still, in the textile sector, waste prevention claimed by policy seems to be a pious wish.

Residual municipal waste composition analysis – New methods for Czech waste management
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
Relevant information about MW composition and proper forecasting of MW composition is crucial for relevant technical and economical modelling and business planning in the field of waste management. These include techno-economical models of MW treatment units, e.g. sorting line, transfer station, energy recovery, waste collection and transport or a regional waste collection and treatment system modelling (Kropáč et al. 2018) and complex business models concerning specific investments in waste management. In this context, there is a project under the Ministry of Environment of the Czech Republic.
