Ways for increased material recycling of material flows from MBT
Dr.-Ing. Matthias KĂŒhle-Weidemeier
By implementing modern thermal and non-thermal waste treatment technologies, waste management hast made a big leap forward. In the last two decades, Central Europe has been the motor of the development. The first decade of this century has been a period of development and installation of new processes in numerous locations. This was followed by nearly a decade of minor progress. This article will analyse the current situation and show how higher recycling rates even from mixed and residual waste can be achieved.
Mechanical biological waste treatment plant for Bangalore west zone
Dr.-Ing. Matthias KĂŒhle-Weidemeier, Dr. rer. nat. Karsten Kanning, Dr.-Ing. Ketel Ketelsen
Proper solid waste management is a problem in many developing countries, especially in their big cities.

EuGH und Vergaberecht – Aktuelle Rechtsprechung
Natalie Hildebrandt
In den EU-Mitgliedstaaten ist das Vergaberecht stark europarechtlich geprĂ€gt. Eine einheitliche Auslegung wird dadurch sichergestellt, dass die Gerichte Vorabentscheidungsersuchen zur Auslegung an den EuGH stellen können bzw. (letztinstanzliche Gerichte) mĂŒssen. Außerdem kann zum Beispiel die EU-Kommission Vertragsverletzungsverfahren einleiten, wenn ein Mitgliedstaat EU-Vergaberecht verletzt hat.

Trocknungsanlagen in Recyclingprozessen
Dr. Mathias Trojosky
Zur Aufbereitung und zum Recycling ist in vielen FĂ€llen eine Trocknung der Grund- und Ausgangsstoffe erforderlich. Entweder werden weitere Aufbereitungsschritte erst durch eine Trocknung ermöglicht, oder das durch den Recyclingprozess gewonnene Produkt bzw. der aufbereitete Reststoff mĂŒssen zur Lagerung getrocknet werden.
Störstoffmanagement in biogenen AbfÀllen
Mag. Dr. Martin Wellacher, Andreas Kunter
Störstoffe in biogenen AbfĂ€llen begleiten die Abfallwirtschaft seit Beginn der getrennten Sammlung vor etwa 25 Jahren, z.B. im österreichischen Bundesland Steiermark seit 1989. Da biogene AbfĂ€lle innerhalb der SiedlungsabfĂ€lle die grĂ¶ĂŸte Wertstofffraktion darstellen, ist fĂŒr diese Abfallfraktion zur Erhöhung von Recyclingquoten in SiedlungsabfĂ€llen vielerorts in Europa eine Zunahme der getrennten Erfassung zu erwarten. Damit steigt aber auch die Störstoff-Problematik aller Marktteilnehmer.
Effektive Geruchseliminierung durch das CSO TerminodourTM System
Dr.-Ing. Jörg Stockinger, Colin D. Froud
Unangenehme GerĂŒche sind bei bestimmten Anlagen (u.a. Abfallbetriebe und Biogasanlagen) immer wieder einer der Hauptstreitpunkte bei der Diskussion mit Anwohnern, aber auch mit Mitarbeitern dieser Anlagen. Hier kann TerminodourTM Abhilfe schaffen. Dieses Ionisationsverfahren bekĂ€mpft die GerĂŒche bereits am Entstehungsort und kann so nicht nur eine BelĂ€stigung der Anlagennachbarn verhindern, sondern auch zu einem deutlich verbesserten Arbeitsklima beitragen.
