Feeding of Refuse Derived Fuels in the Cement Industry

In the energy-intensive industries of cement production, the use of refuse derived fuels (EBS) is in common since several years especially to decrease costs.

Whilst an additional contributionor at least free of charge EBS found their way to the rotary kiln in the last years, nowadays a market pricing is taking place. This situation leads to recognizing more and more the Problems coming along with the use of EBS in the cement industries. Beyond the problems with transport and storage EBS generating challenges to the feeding technologies and to the staff. Among others one reason is that the term “EBS” neither is standardized nor normalized. EBS can be biogenous origin e.g. coffee or rice husks as well as a mixture of different kinds of waste. The user often sees the energy production combined with the reduction of costs only.

Material Flow Analysis of Specific Nanomaterials in C&D Waste in Japan

The objective of this study is to clarify the material flow of specific nanomaterials with focus on construction materials to deviate its release scenarios for the end-of-life phase. The waste stream of construction and demolition (C&D) waste is very challenging because it is generated by both households and industry. Furthermore, the volume of C&D waste in Japan or in Austria is very high. Regarding nanotoxicity, the content of engineered nanomaterials (ENMs) in paints for construction materials is considerable. Chen et al. (2008) pointed out that SiO2 nanoparticles can easily be airborne because of their size. Kaegi et al. (2008 & 2010) have also shown that the nano-fraction of the whitening pigment (TiO2) and nano-Ag was released into surface water under real weather conditions from facade coatings.

In the course of the complete teardown of the area of the former southern and eastern railway stations of Vienna and its complete redesign as a new central railway station of Vienna a substantial diesel contamination was detected. In the perspective of a sustainable solution ÖBB decided to eliminate this spill. For this purpose, initially around 4,500 m³ pollutant-containing soil were excavated and disposed. The remaining area was cleaned by an in situ remediation.

Angepasste Deponieentgasung an veränderte betriebliche Bedingungen

Die meisten heutigen Deponieentgasungsanlagen dürften aus den Jahren ab 1985 bis 1995 stammen, sind also heute ca. 20 bis 30 Jahre alt. In dieser Zeit hat sich nicht nur die Intensität der Gasbildung verändert, sondern auch die Deponietechnik und die Anlage selbst.
