3. Wissenschaftskongress „Abfall und Ressourcenwirtschaft“ 2013, 21.-22. März 2013 in Stuttgart

The 3rd Scientific Congress "Waste and Resource Management" took place in March 2013 under the direction of Prof. Dr.-Ing. Martin Kranert at the University of Stuttgart. The almost one hundred participants were welcomed to the event by Prof. Dr.-Ing. Gerhard Rettenberger on behalf of the DGAW e.V.

For the first time this year, there was a keynote speech at the beginning of the event. Frithjof Finkbeiner, from the Global Marshall Plan Initiative, introduced the Plant for the Planet project to those present. Finkbeiner argued that it is particularly important in times of globalization that each individual fulfills their social responsibility: "Plant trees because that is the easiest way to reduce CO2! If every person planted just 150 trees, that would be a total of 1,000 billion trees." Numerous participants took the opportunity to make a tree pledge during the science congress. You can find more information about this initiative here.

A total of 22 speakers presented papers on the topics of plastics recovery, biological processes, international waste and resource management, recycling, thermal recovery and logistics.
As in previous years, the congress was also accompanied by a poster exhibition. This also gave young scientists the opportunity to present their current research work to an interested specialist audience.
At the beginning of the second day of the congress, Ministerial Director Helmfried Meinel (Ministry for the Environment, Climate Protection and the Energy Sector Baden-Württemberg) awarded three scholarships thanks to the generous support of the ministry and numerous other sponsors. This year, Elisa Seiler (Fraunhofer ICT), Maksim Akhmadiev (University of Perm, Russia) and Agata Rymkiewicz (University of Stuttgart) received funding. Ms. Seiler received a grant of 3,000 euros to fund her doctorate on the topic of "High-quality utilization of fiber composite components from wind turbines". Mr. Akhmadiev is investigating the development of biotechnological processes for the remediation of contaminated sites and will receive a scholarship of 2,500 euros. Ms. Rymkiewicz, who is doing her doctorate on the spatial modelling of waste management data in urban centers, will receive a grant of 1,500 euros. Her case study focuses on the Ethiopian capital Addis Ababa.

Furthermore, a jury of the Advisory Board selected the winners of the Science Prize for Waste and Resource Management in the categories "Lecture" and "Poster". In the "Poster" category, the Science Prize for Waste and Resource Management and a cash prize of 500 euros were awarded to Christian Wolf from the Cologne University of Applied Sciences for his work entitled "Optimizing the operation of waste fermentation plants using online measurement technology and data analysis". In the same category, Helmut Adwiraah from the Technical University of Hamburg-Harburg was also awarded for his work "Foliage as a substrate for fermentation - potential study for Hamburg deciduous trees" and Benjamin Brinkmann from the University of Duisburg-Essen for the poster "Energetic optimization of biowaste recycling in a fermentation plant based on material flow separation into a solid and liquid phase".

The Science Award for Waste and Resource Management for the best lecture and a cash prize of 1,000 euros went to Ann Sophie Kitzler from Hanover University of Applied Sciences and Arts/University of Rostock for her lecture entitled "Cascade utilization of biopolymers - basic investigation into the disposal of biopolymers". Marko Burkhardt from BTU Cottbus for his presentation entitled "Combined material and energy recycling of incontinence material" and Kathrin Weber from RWTH Aachen University for her presentation entitled "Influencing the ash melting behavior of biogenic residues through leaching and additivation".
The congress ended on March 22, 2013 with closing remarks by Prof. Wolfgang Klett, Vice President of DGAW e.V. and Prof. Martin Kranert (University of Stuttgart).

The next Science Congress will take place on March 27 and 28, 2014 under the direction of Prof. Dr.-Ing. Sabine Flamme at Münster University of Applied Sciences.
