Post doctoral researcher: secondary Raw Material Assessment
Delft, 38 hours

Job description
The challenge:

The H2020 project ICEBERG involves 35 partners with researchers from universities, research centres and industries, working closely together to reach a common goal: to design, develop, demonstrate and validate advanced technologies for the production of high-purity secondary raw materials through 6 circular case studies (CCS) across Europe, covering circularity of wood, concrete, mixed aggregate, plasterboard, glass, polymeric insulating foams and inorganic superinsulation materials. The Delft University of Technology has developed sensing technologies like Laser-Induced Breakdown Spectroscopy (LIBS) for continuously assessing the quality of the recycled mineral products to the level of a laboratory prototype. In ICEBERG, we aim to create an industrial methodology and implementation for determining the type of EOL concrete and detecting contaminant particles at very low concentrations in recycled mineral flows. This methodology will be fully integrated with a system that will collect real-time information on the quality of aggregates and their source while being processing aggregates. This information will be stored on the web-based database, where it is accessed by potential users/buyers.

Research in the Resources and Recycling group has a reputation for moving innovative physics into industrial reality, resulting in six spin-out companies to date. The project offers the opportunity for a new post-doc to join our team and work together with innovative industries involved in the ICEBERG project.

The position:
The candidate’s research will be aimed at developing the methodology and complementary data analysis algorithm for online material identification. This research builds on preceding successful Ph.D. and Post Doc research in our group and will form a critical step to achieving industrial adaptation. To this end, the candidate should provide the know-how, data interpretation and process technology to allow for continuous and fast sensor measurements, which is required for on-site materials quality assessment and evaluation of the performance of large-scale concrete recycling processes.

Our group seeks an enthusiastic post-doc with a background in process technology and data analysis. The research involves building a set-up, performing experiments in the lab as well as in the field, and real-time data collection and analysis. The experimental part includes signal processing and mechanical process control. You are interested in the specific fields of physics to be studied and have a good comprehension of English, both spoken and written. Candidates should have an affinity for innovation and are willing to working in multidisciplinary teams. Knowledge of Laser-Induced Breakdown Spectroscopy and/or NIR will be an advantage.

Conditions of employment
Fixed-term contract: 2 years.

The TU Delft offers an attractive, customisable compensation and benefits package, including a discount for health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. An International Children’s Centre offers day care, before- and after-school care and an international primary school. Dual Career Services offers support to accompanying partners. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities. It is an option for the candidate to be employed directly by the Dutch scrap industry.

Employer - Technische Universiteit Delft
Delft University of Technology (TU Delft) is a multifaceted institution offering education and carrying out research in the technical sciences at an internationally recognised level. Education, research and design are strongly oriented towards applicability. TU Delft develops technologies for future generations, focusing on sustainability, safety and economic vitality. At TU Delft you will work in an environment where technical sciences and society converge. TU Delft comprises eight faculties, unique laboratories, research institutes and schools.

Department - Faculty Civil Engineering and Geosciences
The Faculty of Civil Engineering and Geosciences of Delft University of Technology (TU Delft) provides leading international research and education, with innovation and sustainability as central themes. Research and education are closely interwoven and address societal challenges. The Faculty consists of the departments of Transport and Planning, Engineering Structures, Materials, Mechanics, Management and Design, Geoscience and Engineering, Water Management, Hydraulic Engineering, and Geoscience and Remote Sensing.

The research focus of the department Engineering Structures is placed on the investigation and development of resilient, smart and sustainable structures and infrastructures as well as on the structures for energy transition. Within these main themes research is carried out into the dynamics of structures, mechanics of materials related to e.g. climate change, modelling and design of railway systems, multi-scale modelling of pavement materials and structures, reuse of materials, structures and parts of structures, assessment methods for structures, smart monitoring techniques, design methods, replacement and renovation of civil infrastructure and development of new materials and maintenance techniques. The groups are intensively using the unique Macro Mechanics Laboratory for full scale testing, monitoring and modelling of structures to facilitate fast implementation of innovations. The Department delivers a large number of courses both at the BSc and MSc level.

Resources and Recycling is a research group within the department Engineering Structures with strong links to the minerals processing and recycling industries. The group’s ambition is to create breakthroughs in recycling by applying fundamental science to innovative processes and implementing them in collaborations with industry. The ongoing research projects combine theoretical insights and modelling with experiments in the group’s laboratory and pilot plants.
