Are you passionate about understanding the composition of the footwear we use, while exploring more circular options for design for recycling? At the Technical University of Denmark (DTU), we are offering a fully funded PhD position focused on understanding and mitigating the environmental and health impacts of footwear materials. This research sits at the cutting edge of waste and material characterization , material flow analysis and material recycling .

This PhD opportunity is part of the Marie Skłodowska-Curie Doctoral Network SCARPA , a European training network committed to circularity and sustainability in the footwear industry. Through advanced experimental work and modeling, you will help uncover how the composition of shoes will affect the circularity potential, and advice for further improvements. Your research will directly support the transformation of the footwear sector toward safer, more sustainable practices, while equipping you with advanced interdisciplinary skills and international research experience.

Responsibilities and qualifications
You will develop sampling and characterization methods to analyze the composition of current footwear. This includes applying advanced analytical techniques to assess materials in both pre- and post-consumer shoes.

The project aims to:

• Map footwear waste flows in Europe by building a database of common materials in selected footwear categories.
• Provide a foundation for Life Cycle Inventories (LCI) by identifying typical materials and constructions.
• Use Material Flow Analysis (MFA) to explore optimal treatment pathways based on material composition.
• Collaborating with fellow doctoral researchers across the SCARPA network, including those focused on life cycle assessment (LCA).
• Participating in secondments at industry partners and conducting a research stay at the University of Maastricht (UM), which is the double degree partner

You will combine laboratory-based analytical work with modelling approaches to identify trends in material composition, chemical presence, and contamination across the product lifecycle. The candidate will work with state-of-the-art FTIR and XRF equipment in DTU’s Waste Lab and handle large-scale disassembly and sampling.

If feasible, the project will also include Life Cycle Assessment (LCA) in collaboration with DC15.

We consider the following qualifications advantageous:

• You have a solid understanding of environmental assessment and are comfortable working in a laboratory environment. 
• A background in compositional analysis and characterization of materials is an advantage, but not an absolute requirement.
• You are at home in a laboratory environment and not afraid of end-of-life shoes. 
• Most importantly, we are looking for someone eager to translate fundamental scientific knowledge into solutions with real societal impact.

As a person, you are creative, open-minded and can work independently, while also being pragmatic, curious and driven in your research. Collaboration is central to your work, and you bring strong social and team skills. You can communicate scientific topics clearly and effectively to both experts and non-specialists. Proficiency in English is required. 

You must be compliant with MSCA mobility rule: not have resided or carried out your main activity (work/study) in Denmark for more than 12 months in the 3 years immediately prior to recruitment.

You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.

Approval and Enrolment  
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU's rules for the PhD education . 

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.

Salary and appointment terms 
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union. 

The period of employment is 3 years. Starting date is preferably 1 February 2026 or soon thereafter. The position is a full-time position.

Application procedure 
Your complete online application must be submitted no later than 31 October 2025 (23:59 Danish time) . 

Applications must be submitted as one PDF file containing all materials to be given consideration. To apply, please open the link "Apply now", fill out the online application form, and attach all your materials in English in one PDF file . The file must include:

• A letter motivating the application (cover letter)
• Curriculum vitae 
• Grade transcripts and BSc/MSc diploma (in English) including official description of grading scale

You may apply prior to ob­tai­ning your master's degree but cannot begin before having received it.

Applications received after the deadline will not be considered.

All interested candidates irrespective of age, gender, disability, race, religion or ethnic background are encouraged to apply. As DTU works with research in critical technology, which is subject to special rules for security and export control, open-source background checks may be conducted on qualified candidates for the position.
