Teaser Text

Are you an enthusiastic early career researcher who is keen to work on the European steel transition and life cycle assessment (LCA)? Are you interested in developing ex-ante models for material flows and LCAs? Then this could be the ideal PhD position for you!

The European steel industry is undergoing a major transition to achieve climate neutrality while maintaining global competitiveness. Central to this transition is the replacement of conventional blast furnace–basic oxygen furnace (BF-BOF) steelmaking with lower-carbon electric arc furnace (EAF) production based on recycled scrap and direct reduced iron (DRI/HBI). Ensuring sufficient availability of high-quality feedstocks for these production routes is a key challenge, as future demand will increasingly require the use of more diverse and lower-quality material streams.

This PhD position is embedded in the Horizon Europe project DiversEAFy, an interdisciplinary consortium that aims to make future EAF steelmaking more resilient through feedstock upgrading, flexible mix design, AI-supported process steering, and valorization of EAF slags. The PhD candidate will contribute to understanding how future changes in material availability, steel quality, recycling systems, and technology deployment affect the environmental performance of the European steel sector and its transition towards a circular and low-carbon economy.

What you will do

The PhD is expected to cover:

Developing dynamic material flow analysis (dMFA) models to quantify steel stocks, flows, scrap generation, and scrap quality across the EU27, including the tracking of key impurities and tramp elements throughout the steel life cycle.
Assessing how product lifetimes, collection systems, sorting technologies, and recycling strategies influence the future availability and quality of scrap for electric arc furnace steelmaking.
Coupling material flow models with prospective life cycle assessment (LCA), market analysis, and technology deployment scenarios to evaluate future steel production pathways and circular economy strategies up to 2050.
Quantifying the environmental impacts of primary and secondary steel production under different future scenarios, including climate change, energy and resource use, water consumption, waste generation, and emissions, while conducting sensitivity and uncertainty analyses to assess the robustness of results.

The work will involve close collaboration with researchers working on metallurgy, industrial ecology, circular economy, life cycle assessment, and sustainability transitions within the DiversEAFy consortium.

Where you will work

The PhD candidate will be employed at Leiden University’s Institute of Environmental Sciences (CML) and will work closely with partners in the DiversEAFy project.

The research combines expertise in industrial ecology, material flow analysis, life cycle assessment, circular economy, and sustainable industrial systems. Through DiversEAFy, the PhD candidate will collaborate with leading academic and industrial partners across Europe working on the future of low-carbon steel production.

Leiden University offers an inspiring interdisciplinary research environment with strong collaborations across academia, governmental organizations, and industry stakeholders working on sustainability transitions, circular economy strategies, and environmental assessment.

The position provides an excellent opportunity to contribute to cutting-edge research supporting the decarbonization and circular transformation of one of Europe's most important industrial sectors

What you bring

The successful candidate should have:

A completed MSc degree in environmental sciences, industrial ecology, sustainability science, engineering, materials science, systems analysis, or a related field;
Strong analytical and quantitative skills;
Interest in interdisciplinary environmental assessment, circular economy, and sustainability transitions;
Interest in material flow analysis, life cycle assessment, environmental modelling, and scenario analysis;
Experience with programming and/or data analysis (e.g. Python, R, MATLAB, GIS);
Excellent written and spoken English skills;
Ability to work both independently and collaboratively in an interdisciplinary research team.

What we offer

We offer an initial one-year contract, with an option to extend for up to 4 years based on performance, following the pay scale P in accordance with the Collective Labour Agreement for Dutch Universities. Salary ranges from € 3.059 in the first year to € 3.881 gross per month in the final year based on a full-time position .

At our institution, we believe in flexibility and work-life balance! With a full-time position (38 hours per week), you are entitled to 232 vacation hours per year , which is equivalent to 30.5 vacation days (based on a 38-hour work week). If you value flexibility, you have the freedom to adjust your working hours. For example, you could choose to work 40 hours per week, earning extra compensation hours. Alternatively, if you prefer a shorter work week, you can work 36 hours per week by using some of your vacation days to create more time for yourself. You’ll work closely with your supervisor to tailor your schedule in a way that suits both your needs and the team’s.

In addition, we offer a comprehensive benefits package, including:

Holiday allowance (8%) and an end-of-year bonus (8.3%)

An attractive pension scheme with ABP, ensuring your financial well-being both now and in the future

Extensive options for secondary employment conditions: You can explore options such as sabbaticals, paid parental leave, and the individual choices model, which allows you to exchange leave days and/or salary for benefits like an advantageous sports subscription, bicycle scheme, and childcare options

Hybrid working options: If your role allows, you can enjoy the flexibility of working from home within the Netherlands

Home-working allowance: You’ll receive a home-working allowance (for both workdays and internet), and the university will provide you with a laptop and support for creating a comfortable home office

PhD student support: As a PhD student, you’ll be part of the Graduate School of Science, which offers a variety of training courses at three levels: professional courses, skills training, and personal effectiveness

We are committed to offering a flexible, supportive, and rewarding work environment, designed to help you grow both professionally and personally.
