1st Scientific Congress "Waste and Resource Management" 2011 - March 29-30, 2011 in Straubing

Prof. Dr. Gerhard Rettenberger, DGAW board member and initiator of the congress, welcomed the over one hundred participants on behalf of the DGAW on 29.03.2011 and emphasized in his speech the need to offer young scientists working in the field of waste management a platform where they can present the results of their theses. The congress thus not only serves the scientific exchange, but also the practitioners who want to get an idea of the state of science and future developments.

After Prof. Dr.-Ing. Martin Faulstich, Head of the Chair of Raw Materials and Energy Technology at the Technical University of Munich, introduced the work of the chair and gave a brief overview of the topics covered at the congress, the 25 speakers, moderated by professors from German-speaking chairs, presented their specialist papers on topics from the fields of material flows, waste management in developing and emerging countries, recycling, organic waste and landfills.

Parallel to the lectures, a poster exhibition was held in the foyer of the Science Center, where almost 30 young scientists presented their concepts for the further development of waste technology and resource management.

At the end of the first day, the approximately 110 interested participants had the opportunity to exchange experiences and ideas in an informal atmosphere at an evening event with a buffet and background music.

At the end of the event on March 30, 2011, a jury of the Advisory Board selected the best three contributions in each of the categories "Presentation" and "Poster".
In the "Poster" category, the Science Prize for Waste and Resource Management and a cash prize of EUR 500 were awarded to Ms Marlies Hrad from the University of Natural Resources and Life Sciences, Vienna for her work entitled "Investigations into the methane oxidation performance of different cover layers before and during in-situ aerobization".

Ms Gülsen Öncü from the University of Stuttgart was awarded in the same category for her work "Influence of Aerobic In-Situ Stabilization of Old Landfills on Leachate Quality and Quantity" and Mr Thomas Schnellert from the Bauhaus University Weimar for the poster "Development of a separation process for gypsum-contaminated concrete rubble".
The Scientific Award for Waste and Resource Management for the best presentation and a cash prize of 1000 euros went to Ms. Eva Hamatschek from the Technical University of Munich for her presentation "Thermal utilization of municipal waste in emerging countries".
Awards in the "Lecture" category went to Ms Han Zhu from the University of Stuttgart for her lecture entitled "Evaluation of Landfill Methane Emission rates using Tuneable Diode Laser Absorption Spectrometer" and Mr Dennis Blöhse from the Ostwestfalen-Lippe University of Applied Sciences for his lecture entitled "Energy recovery of organic municipal and industrial waste through hydrothermal carbonization (HTC)".

The cash prizes were made possible by the sponsorship of numerous private and municipal companies in the industry, who also supported the event with their presence.
With closing remarks by Mr. Thomas Obermeier, President of the DGAW, the congress ended on 30.03.2011 at around 4 pm. According to Obermeier, March 29 and 30, 2011 will go down in the history of waste management as the days on which the 1st DGAW Science Congress took place. An important aim of the congress was to strengthen cooperation between science and industry. In his address, President Obermeier also emphasized the new demands on the raw materials and resources industry in light of the new draft legislation and the important role of science in its further development.

The next Science Congress will take place at the University of Rostock in 2012.
