Euro 1.4 million for research project on “Contribution of material cascade utilization to sustainable resource management”
A car tire at first, in a second life maybe an insulating board or the sole of a shoe, then floor covering in a third life – if a raw material made from crude oil, which to this day remains the main constituent of car tires, is used several times and in multiple stages it is called “cascade use”.
This will be the focus of a new junior research group at the Carl von Ossietzky University Oldenburg, which is led by Dr.-Ing. Alexandra Pehlken and will commence work in the coming days.
The interdisciplinary junior research group is called “Contribution of material cascade utilization to sustainable resource management” or short “Cascade Use” and will be sponsored by the Bundesministerium für Bildung und Forschung (BMBF)’s “Global Change” programme with nearly Euro 1.4 million over a period of four years, with the possibility of adding another year if necessary.
The research group is part of the School of Computing Science, Business Administration, Economics and Law of the University of Oldenburg and consists of five co-workers. In addition to the project leader and adjunct, the group will give three doctoral students the opportunity to do research and obtain their doctorates.
One of the junior scientists is from the Shanghai Jiao Tong University. “Through our close cooperation with the Chinese university we will be able to gain valuable impulses”, Pehlken asserts. “We are going to collaborate with Professor Chen Ming, one of the most well-known Chinese recycling experts. Among other things, analyses of this exploding market in Asia will very much enhance our research. Moreover, we hope that together we can contribute to increasing the acceptance of recycling in China.”
The aim of the “Cascade Use” research is to utilize raw materials within the economic cycle for as long as possible and thus protect the environment. “This not only offers ecological benefits, but also very large and so far mostly untapped economic potentials” says Pehlken.
The group deals with the question of how materials are integrated into product life cycles and when they become available for reuse or remanufacturing.
With this issue in mind, the group develops a tool to assist decision-makers in economics, administration and politics in recognizing and evaluating the potentials for optimal resource use with the least possible environmental impacts. To do so, the scientists employ material flow analyses with reference to technological, ecological and economic aspects. Developing a method for estimating the life cycle-spanning material availability, they also, for example, determine the CO2 emissions within the recycling hierarchy.
The group particularly focuses on primary resources, such as iron, copper, aluminium and magnesium, as well as on the valuable and often critical rare earth metals. These include europium, which is needed for fluorescent lamps and plasma screens, and neodymium, which is part of the strong, small permanent magnets, high performance microphones, high-efficiency speakers, wind power turbines and high performance electric motors. Hardly any of today’s key technologies could function without the use of rare earth elements.
About Alexandra Pehlken:
Alexandra Pehlken (42) studied mining at the Rheinisch-Westfälische Technische Hochschule Aachen (RWTH Aachen) where she also gained her doctorate as engineer in 2002. The scientist, who was born in Oldenburg, has carried out research in Germany,, South Africa and China. Furthermore, a Lise-Meitner-Scholarship brought her to the ‘Natural Resources Canada’ Institute in Ottawa (Canada), where she dealt with the recycling of used car tires. Pehlken also led several research projects, for example, a project on feed production at the ‘Institute for Integrated Product Development’ (BIK) at the University of Bremen. Since 2012, the engineer has been working as a project leader in the field of energy and society at the Center for Environmental and Sustainability Research (COAST) of the University of Oldenburg. Besides, she is involved in national and international panels. In 2011, Pehlken was appointed Associated Junior Fellow at the Hanse-Wissenschaftskolleg Delmenhorst (HWK).

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
