Material vs. Energy Recovery – An Assessment Using Computational Tools NERUDA and JUSTINE
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
The paper describes a continuing work on a unique approach of a Waste-to-Energy (WtE) Project assessment and related risk analysing. It is based on long time developed computational tools NERUDA and JUSTINE which support decision making in the field of waste Management.

New Trends of Circular Economy in the City of Velika Gorica
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
For a number of years, the city of Velika Gorica has been developing waste management projects, and the actual waste management system situation of the city of Velika Gorica is the result of its gradual and strategical development since the late 1990s. The waste is a very important resource in the concept of circular economy and the construction of infrastructure in Velika Gorica will ensure foundations for circular economy.

Society and legislation are focusing more and more on sustainability due to ecological and economic reasons. This means that materials in general have to be used in a more sustainable way and that waste has to be turned into a valuable resource again. Searching for sustainable approaches the resource efficiency has come into play.

Assessing the Resource Efficiency of Biorefineries Using Organic Residues - Methodology and Examples
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
The IEA Bioenergy Task 42 “Biorefining” has the following definition on biorefining: “Biorefining is the sustainable processing of biomass into a spectrum of bio-based products (food, feed, chemicals, and materials) and bioenergy (biofuels, power and/or heat)”. Various types of organic residues are a sustainable resource that offers great opportunities for a comprehensive product portfolio to satisfy the different needs in a future BioEconomy.

Is an Effective Recovery of Heavy Metals from Industrial Effluents Feasible?
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Metallic elements and their compounds represent, depending on their concentration and bioavailability, a potential hazard to the health of humans, animals, plants and other living organisms. Large volumes of water contaminated with heavy metals or radioactive elements are generated e.g. during mining processes or industrial productions. In general, legal limits are low and strict to ensure purifying of wastewater.

European Harmonization of Methods to Quantify Methane Emissions from Biogas Plants
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
In the past years, attempts were undertaken to quantify single emission sources as well as overall emissions from biogas plants using on-site (direct) and remote sensing (indirect) methods. While measurements on site often focus on one type of CH4 sources, remote sensing methods cover the overall emission plume. Among the current available emission measurement techniques, none is in a position to be recognized as the best international reference. Therefore, the establishment of a scientifically based standardization and harmonization of methods would greatly contribute to the assessment of the fugitive emissions from biogas plants.

Changes in the Solid Waste Composition of Metropolitan Cities: A Case Study for Izmir
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Knowledge of municipal solid waste amount, composition and characterization in an area plays a key role for the decision makers to determine the proper waste management system and final disposal options. Depending on various factors such as population increases, climatic changes, lifestyle habits, and socio-economic developments, the solid waste amount and composition continuously change in time. Lack of waste data is a big problem in Turkey which is a developing country with young population and rapid industrialization. There are numbers of composition and characterization studies conducted in different districts in Turkey by independent researchers. Nevertheless, continuous regular data is necessary for proper solid waste management.

Solid Recovered Fuel – Optimization of Plants in the Polish Economic Reality
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Waste management and district heating systems, especially in scope of smaller facilities, require a thorough modernization. In addition, the existing model of these systems, especially for small and medium-territorial units, is not able to meet new requirements of the EU policy in the field of resources and energy efficiency. It is therefore necessary to seek for the new model which quality will be closer to the requirements of the overall strategy of the European Commission, whose key elements includes the impact of the project on the social prosperity and the preservation of the principles of sustainable development.

Recycling of Phosphorus - Application of Slag and Ashes in Agriculture
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Phosphorus is of essential importance in plant growth and yield. For many decades Thomas slag from basic steelmaking has been a highly appreciated phosphorus fertilizer in agriculture. In the 1960s changes in steelmaking were the reason for declining amounts of phosphorus slag in steelmaking until in the midst 1990s no phosphorus slag was any longer available for agriculture purposes.

Effect of Organic Carbon in MSWI Bottom Ash on the Mobilization of Heavy Metals
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Nowadays municipal solid waste incinerators (MSWI) are playing a major role in waste Management activities. Especially in Switzerland, where the morphology of the country is quite disadvantageous, burning the municipal waste material seems to be the most favorable way to handle These types of waste.
