Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben Current Practices and Future Management Options of Medical Waste Management in TurkeyAssist. Prof. Dr. Hasan Sarptaş, Bırcan Dındar, B. Sakız, Prof. Dr. Ertugrul Erdin
Medical wastes constitute a larger portion of infectious wastes that are potentially dangerous since they contain pathogenic agents. While sustainable management of municipal solid waste, wastewater sludge and construction and demolition waste gain significant attention, medical waste has not attracted the same level of attention as other types of wastes, especially in developing countries. Therefore, medical waste management is still a critical issue in many countries due to ist potential environmental hazards and public health risks.
Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben Improved Eco-Design of Lithium-Ion Battery Packs for Simplifying the Recycling ProcessMag. Therese Schwarz, Bettina Rutrecht, Alexander Curtis, P. Handel, J. Worschech
Due to the increasing numbers of lithium-ion batteries in electric cars as well as in electric and electronic equipment, the design and recycling of batteries is gaining increasing importance. This fact demands for an efficient and holistic battery concept as well as a future concept for recycling and treatment.
Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben New Sampling Technique for Coarse Waste Materials from BalesDr. Martin Wellacher, T. Berto
Environmental analysis has to deal with the possible sources of error. It is known that the process of sampling is the major source of error (up to 90 % of the total error). The sampling error is scarcely considered, while the insignificant analysis error is included with up to three decimals. However, there are not yet any effective methods to reduce the sampling error, mainly because of the inhomogeneous properties of waste.
The aim of the project was to improve the sampling process with the same or an even higher accuracy of the analysis results.
TK Verlag - Fachverlag für Kreislaufwirtschaft Fully Automated Sorting Plant for Municipal Solid Waste in Oslo with Recovery of Metals, Plastics, Paper and Refuse Derived FuelDr.-Ing. Benjamin Eule
In order to treat household waste Romerike Avfallsforedling (ROAF) located in Skedsmorkorset north of Oslo, Norway required the installation of a mechanical Treatment facility to process 40,000 tpa. Together with a Norwegian based technical consultancy Mepex and German based technical consultancy EUG the project was tendered and the plant build against a technical specification. In 2013 the project was awarded to Stadler Anlagenbau and since April 2014 the plant is in operation with an hourly throughput of thirty tons. The input waste contains specific green coloured bags containing food waste which is collected together with the residual waste from the households. The process recovers successfully the green food bags before the remaining waste is mechanically pre-treated and screened to isolate a polymer rich fraction which is then fully segregated via NIR technology in to target polymers prior to fully automated product baling. Recoverable Fibre is optically targeted as well as ferrous and non-ferrous metals. All food waste is transported off site for further biological treatment and the remaining residual waste leaves site for thermal recovery. In 2015 the plant has been successfully upgraded to forty tons per hour and remains fully automated including material baling.
TK Verlag - Fachverlag für Kreislaufwirtschaft Plastics Recycling and Energy Recovery Activities in Poland – Current Status and Development Prospects –Dr.-Ing. Kazimierz Borkowski
The waste disposal system in Poland is one of the least advanced in Europe. Despite great efforts over the last 20 years municipal waste landfilling has only reduced from 95 percent in 1991 to 73 percent in 2010. This still means that millions of tonnes of post-consumer waste continue to be landfilled.
TK Verlag - Fachverlag für Kreislaufwirtschaft Disposal of Carbon Fiber Reinforced Polymers – Problems During Recycling and Impacts on Waste IncinerationMarco Limburg, Prof. Dr.-Ing. Peter Quicker
Carbon fiber reinforced polymers (CFRPs) are becoming increasingly more ubiquitous in our daily lives. CFRPs are composite materials, consisting of carbon fibers with high mechanical capabilities and a formative polymer matrix. The production process of carbon fibers is complex and energy intensive, thus making CFRPs more expensive than comparable metal materials. The advantage of CFRPs lies in their weight; metal materials of the same properties weight up to five times as much. This makes CFRPs especially valuable in areas, where weight and cost directly correlate, but high mechanical properties are still essential.

Sorting of Black Plastics Using Statistical Pattern Recognition on Terahertz Frequency Domain DataChristian Brandt, Michael Kieninger, Andries Küter, Dirk Nüÿler, Robin Gruna, Thomas Längle
The sorting of used plastics is an ever-growing market eld which is further pushed by new EU regulations in, e.g., car recycling. Modern recycling techniques require pure or almost pure fractions
of polymers. These pure fractions can be generated from waste using modern sorting technologies
based on specic mechanical, electrical and chemical material properties such as density, conductivity
and melting point.
TK Verlag - Fachverlag für Kreislaufwirtschaft Treatment of Bottom Ashes of Waste-to-Energy Installations – State of the Art –Frans Lamers
Waste-to-Energy installations generate around 25 percent bottom ashes, that may be considered non-hazardous waste. On a total of 76 million tonnes of incinerated waste, this means a total of roughly 19 Million tonnes of bottom ashes.
Wasteconsult international The dry anaerobic DRANCO technology applied to the organic fraction of MSWWinfried Six, Luc de Baere
The DRANCO technology was developed in the eighties as one of the very first anaerobic digestion technologies for municipal solid waste (MSW). A first demonstration plant was erected in 1984 in Ghent, Belgium. At present about thirty DRANCO installations are constructed in about fifteen different countries. This paper describes these DRANCO installations treating the organic fraction of MSW, integrated in a mechanicalbiological treatment plant (MBT). It does not describe DRANCO installations dealing with source separated biowaste.
Wasteconsult international Application of paper sludge for co-fermentation in MBTMeike Walz, Dipl.-Ing. (FH) Corinna Hentschke, Prof. Dr.-Ing. Achim Loewen, Dipl.-Ing (FH) Christian Bienert
During the production of paper and packaging materials, various paper sludges are producedas waste material. This research project, funded by the DBU, investigates cofermentation in the digesters of mechanical biological treatment plants (MBT) as an ecological and economical solution for the use of these residuals. Three types of paper sludge from different ways of paper production were analyzed. The slurries were checked for possible inhibition effects upon the biogas process in MBT and their Biogas yield. First results have shown that the co-fermentation of paper sludges in digesters of MBT plants could be useful. The results found so far do not show definite inhibition effects.
IWARU, FH Münster High efficient recycling route of WEEEFabian Diaz, Professor Dr.-Ing. Dr. h.c. Bernd Friedrich
A novel Pyrometallurgical recycling route is being designed to recycle complex metallic materials containing plastics such as waste electric and electronic equipment (WEEE). The new proposed methodology overcomes huge challenges like improved recovery of valuable metals, better control of hazardous substances, improved process control and recycling capacity. The recycling process for E-Scrap would be developed in such way that no waste would be obtained and all products and byproducts could be saleable materials.
