A New Methodical Approach for Environmental Impact Assessment (EIA) Related to MSW Landfills in Russia
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Nowadays, the most widespread method of MSW disposal in Russia is landfilling, using the most primitive landfilling technology. On an average, only 3-4 % of municipal solid waste is recycled, but the majority of waste is taken to dumps — there are about 11 thousand in Russia with an area of more than 11,000 hectares of land. About 82 billion tons of waste is buried in them. This fact requires that a full-fledged and accurate assessment of this activity and its influence on Environment has to be carried out before its implementation.

New Sampling Technique for Coarse Waste Materials from Bales

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.

A Common Framework for Assessing Life Cycle Impacts of Food Waste Prevention, Valorisation & Treatment
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
The European Waste Framework Directive 2008/98 EC mandates that member states should take measures to encourage waste prevention and management options which deliver the best overall environmental outcome from a life cycle perspective, even if these differ from the waste hierarchy. Life cycle assessment (LCA) is a well-established tool to compare and evaluate such environmental life cycle impacts of food (waste) systems. However, as a tool, LCA leaves a lot of freedom to the assessor to determine key aspects. Notable aspects can be found mainly as part of the goals and scope definition, such as the functional unit, the system boundaries or the handling of multiple outputs. This influences the outcome of the assessments.

Improved Eco-Design of Lithium-Ion Battery Packs for Simplifying the Recycling Process
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
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.

Reducing Leachate Treatment Costs, But How?
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Leachate processing at landfills places significant demands on process technology. Landfill leachate contains a cocktail of various pollutants. In addition to biodegradable nitrogen compounds, this also includes a large number of other organic and inorganic pollutant groups that are fully or partially non-biodegradable. These substances have to be removed from the landfill leachate through cost-intensive physicochemical treatment. The requirements placed on the treated leachate depend on the way it is discharged. Legal framework specifications define the limits for direct or indirect dischargers.

A System Model of the Recycling of Critical Raw Materials from Wastes and By-Products in Austria
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
The development of the high-technology industry plays an important role for the economic growth particularly in industrialized countries. This industry has a big demand on raw materials which are considered critical due to their economic importance and their associated supply risk (e.g., REE, gallium, germanium, PGE and tantalum). Subsumed under the collective term critical raw materials (CRMs), 14 of these materials were first defined by the Resource Initiative of the European Commission in 2010 and have been updated to 20 in 2014, since the supply with CRMs is crucial for European economies. In consequence the Austrian economic location, being part of the European economic area with a developing high-technology industry also depends in CRMs. Therefore also the Austrian Ministry for Transport, Innovation and Technology defined a specific list of materials that are critical or potentially critical for the country and the future manufacture of technological products as well.

Lessons Learned on the Way to Realize and Operate MBT Plants
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Under aspects of climate protection the fermentation process in AD-sections of an MBT should be favoured for the separated organic (wet) fraction. Best performing plants are not only separating some recyclables – in addition to separate collection systems – and producing electricity form the biogas but are also utilizing the heat produced in water cooling circuits and exhaust gas heat. MBT-plants are regarded as a suitable solution to reduce methane-emissions from landfills, if such plants are constructed and operated well and using state-of-the-art emission reduction equipment.

Current Practices and Future Management Options of Medical Waste Management in Turkey
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
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.

Practices and Problems in MSW Management for Bio-Waste in Turkey
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Regarding the integrated solid waste management in Turkey, tremendous efforts have been given to the transposition and implementation of related EU directives. The “By-law” on General Principles of Waste Management (05.07.2008), the “By-law” on Landfilling of Waste (26.03.2010) and many others have been enacted and the management of municipal solid wastes and other special and hazardous wastes has been improved.

Current State of Biowaste Management in the Czech Republic
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
The Czech Republic currently strives to comply with its obligations towards EU biowaste management requirements. The decisive Council Directive 1999/31/EC on the landfill of waste obliges all the EU member states, including the Czech Republic, to drastically reduce landfilling of biodegradable wastes or biodegradable municipal waste.
