Alexandra Pehlken is the head of Working Group 1, which focusses on data gathering, collation and assembly related to WEEE, assisted by Clayton Burger.
New Study: Cascade Use complements the Management of Product Lifecycles
CCU has published their approach on cascade use in the recently published paper: Cascade Use and the Management of Product Lifecycles (Authors: Matthias Kalverkamp, Alexandra Pehlken, Thorsten Wuest) and was selected as cover story from the mdpi publisher (out of 176 submitted articles): http://www.mdpi.com/2071-1050/9/9/1540. The study explores the challenges related to the End-Of-Life phase of products in circular systems within the commonly established frameworks of product lifecycles. The researchers criticize that the current focus on producer-centric supply chains neglects the real complexity at the end-of-life. They argue in favor of the ‘cascade use methodology’ as an extension to current product lifecycle models which would support the identification of additional value-add and resource conservation at the end-of-life of products and materials. They analyze and discuss their approach using case studies.
The study is published in the open access journal Sustainability.
Yuan Shi, a master student of the School of Automotive Engineering from Wuhan University of Technology, China, was studying for 3 months at CCU. She was involved in the research topics of the Cascade Use group and did research on Chinese data for scrap tires and new energy vehicles in China. Her research and study visit was possible through funding within the IPID4ALL program of the DAAD. It was an ongoing research exchange, following up of a short visit of her tutor Prof. Jinsheng Xiao in 2016.

The team from Cascade Use collaborates with Professor Chen Ming from Shanghai Jiao Tong University since the beginning of the research group. In April 2017 both institutes organized an international conference AARTI 2017 „International Symposium on Cascade Use of Automotive Parts 2017“. The jointly organized conference followed by a knowledge exchange workshop for doctoral students. Providing a wealth of insight and research discussions on the complex socio-political differences between the Chinese economy and Western economies, these events were very well received and benefited all participants.

The conference took place on April 21st 2017 and was hosted at the Blue Palace Hotel in the historical district of Jiading, near Shanghai, China. Chaired by Professor Chen Ming of STJU, the international conference gleaned a valuable cross-section of China’s economic landscape for recycling through various international presentations. The plenary sessions were presented by a keynote of Deputy Professor Alexandra Pehlken of Cascade Use and Professor Steven Young of Waterloo University, Canada. International perspectives on remanufacturing and recycling were investigated, focusing on the “three continent” approach led by Professors Pehlken, Chen and Young, representing Germany, China and Canada respectively. Other presentations at the conference included innovative technologies and prospects from Japan with the theme of IT in recycling, critical reflection on reuse and regulation of critical materials from Canada with a discussion of batteries as a case study, ELV recycling and the current E-Mobility landscape, and finally closed-loop marketing strategies. The symposium provided useful partnerships and presented networking opportunities which would be extremely difficult to have initiated outside of China.
The knowledge exchange workshop took place on April 24th with invited stakeholders from Cascade Use and STJU. The key focus was to facilitate interdisciplinary and international insight transfer between Germany and China in the car recycling and remanufacturing domains. With each doctoral research theme presented, the workshop gave participants an opportunity to develop soft skills while simultaneously opening channels for further collaboration and communication. Useful insights into the infrastructure in China were discussed, with emphasis on data and reporting requirements of private enterprises and governmental regulations. Key outcomes of the workshop are new contacts, data exchange and a common research interest which will culminate in a publication, further expanding on the “three continent” approach between Europe (Germany), China and Northern America (Canada).
Starting April 1, 2017, the head of the Cascade Use research team has been appointed as the head of the Department of Resource Management and Waste Technology at the University of Kassel as a supervising professor.
The Department of Resource Management and Waste Management at the university of Kassel is located in the Faculty of Civil Engineering and Environmental Engineering and was founded by Prof. Dr.-Ing Arnd and was led until his retirement in March 2017.
The subject area deals with pre- and post-treatment processing of waste and residue treatment with disposal procedures. The focus is placed on buildings and plants through process engineering, while also investigating the landscape from the individual process steps to the high level processes of each facility.

The true energy consumption of data centres is an open question. The “TEMPRO” project takes the entire life cycle of the infrastructure into consideration.
With this goal, project “Total Energy Management for Professional Datacentres” (TEMPRO) was launched in January 31st, 2017. The initial kick-off meeting took place in Oldenburg. Instead of analysing current operations of a data centre, the TEMPRO team has taken a holistic approach of investigating the entire lifecycle of the devices under consideration, from raw material to recycling opportunities.
Head of the collaborative project with several research, municipal and industrial partners, Dr. Alexandra Pehlken, who also leads the Cascade Use research group is supported by the federal ministry of economics and energy. The project runs for three years with funding of 2.2 million Euros, of which 600 000 is directed to Oldenburg. With the help of these resources, the CCU team is bolstered by a new doctoral student: Fernando Penaherrera. The cascade utilization strategies developed in the research group are thus expanded from cars to the IT industry.
