Utilization of bottom ash from the incineration of separated wastes as a cement substitute
Filip Kokalj, Niko Samec, Bernardka Jurič, 2005, original scientific article

Abstract: Waste incineration is still an essential technology in the concept of integrated waste management. Most of the combustion residues are incinerator bottom ash. It has been discovered that incinerator bottom ash from the incineration of separated waste in the primary chamber of the modular two-stage incinerator mainly consists of metal oxides, especially SiO2 and CaO, in proportions that are quite similar to those in cement and so the feasibility of its application as a substitute for cement in concrete was investigated. It was found that after 28 days, the flexural and compressive strengths of the binder using bottom ash were practically comparable with those of a pure cement mixture. The results show that it is reasonable to use a binder containing incinerator bottom ash for applications in which an early-stage lower strength of concrete element is acceptable.

3D-CO2-modelling for waste management in Styria/Austria
Wolfgang Fischer, Danko Simic, 2016, original scientific article

Abstract: The paper in hand focuses on a calculation model which had been developed for calculating the CO2 production of a garbage truck during a waste collection tour. The challenge is the integration of not only the distance and loading weight but also the different petrol consumption and therefore CO2 production in regard to the topography of the whole collection tour. Additionally the increase of waste load at each stop during the whole collection tour has to be taken into account for the calculation. The model has been developed on basis of Excel. In order to get the real data from the collection tours these had been accompanied. There not only the whole tour but also all waste bins and stops for loading the waste had been registered. Both GPS (Global Positioning System) and RFID (Radio-Frequency Identification) had been used. The huge amount of data had to be scrubbed. This process of amending or removing data in a database that is incorrect, incomplete, improperly formatted, or duplicated was an important step to have reliable data for further calculation processes. The identification of the CO2 production during a waste collection tour including the topography and continuous revenue load had not been done so far and allows the identification of tour segments with lower but mainly higher or very high ecological impact. However, this is the basis for further discussions about options for optimizing the actual tours and habits of waste collection. That approach is part of a more comprehensive investigation of waste collection tours with general focus on economic, ecologic and social potentials for optimization.

Environmental management & audit 4: Environmental assessment - featured articles
2016, scientific monograph

Abstract: The present scientific monograph, entitled “Environmental management & audit“, is the result of three years’ work on an international project entitled “Environmental management in Russian companies – retraining courses for the sensibilization for and integration of Eco-Audit programs in corporate decision-making (RECOAUD)”. Within its more than 600 pages, the monograph features interesting texts written by 31 authors from the European Union and the Russian Federation, edited by dr. Borut Jereb, Darja Kukovič and dr. Daria Meyr. The monograph “Environmental management & audit“ is composed of four books: “Scarcity and Introduction of Environmental Management”, “Management Systems”, “Controlling and Stakeholders”, and “Environmental Assessment” (Featured Articles). These four topics reflect the complexity, heterogeneity and multidisciplinary of the project Tempus RECOAUD. The reader of the monograph gets a comprehensive overview of theoretical perspectives of environmental management and audit in the chosen areas. Furthermore, the monograph also highlights the results of research in the field of environmental management and audit as well as trends and challenges in the development of this field. Providing insight into theoretical and research findings, the monograph will prove useful to both practitioners and researchers in the field of environmental management and audit; it can also be used for study purposes.
