PhD Position Modelling and Optimization of Processes to Recycle Low-grade Biogenic Waste

PhD Position Modelling and Optimization of Processes to Recycle Low-grade Biogenic Waste

As the Netherlands phases out fossil feedstocks, carbon becomes a critical raw material for everyday materials (e.g., plastics, asphalt, composites, batteries). While renewable carbon can come from biogenic waste, low-grade biowaste is often wet/contaminated and is therefore typically downcycled (e.g., low-value compost/animal feed) or incinerated, which also creates problematic bottom and fly ash residues and can spread persistent contaminants. This leaves a major gap: how to valorize low-grade waste into high-value products beyond biofuels/biogas at industrially-relevant scales? The NWA-ORC funded consortium project ABEL addresses this challenge by combining technology development with process modelling and assessment across the waste value chain. The members of the consortium include 4 other research Universities, 2 Universities of Applied Sciences, and companies across the value chain of biomass. In this PhD project, you will develop state-of-the-art methodologies to: Design and scale up novel processes for the valorization of low-grade biowaste. Model transition pathways for the ABEL technologies to integrate into existing or new value chains. Minimize energy and resource use through efficient heat exchange, waste heat recovery, and optimized process conditions. Assess and reduce environmental impacts, such as greenhouse gas emissions. Validate models with literature and consortium data and in case studies defined by the consortium. The PhD would join the Circular PSE group led by Dr. Somoza-Tornos and work together with other researchers modelling emerging technologies for the de-fossilization of the chemical industry. They would also be part of the Process Systems Engineering (PSE) section at TUDelft, that comprises a professional team dedicated to advanced computational research, with a collective focus on advancing the PSE field to bring new insights and sustainable developments.

The ideal candidate will be an ambitious, proactive, reflective, and results-driven researcher. We are looking for the following: MSc degree in chemical engineering or similar field (essential). Strong background in chemical process modelling and design (essential). Prior experience with process optimization (desirable). Prior experience with techno-economic analysis and life cycle assessment (desirable but not required). Strong collaboration, communication and writing skills.

Doctoral candidates will be offered a 4-year period of employment in principle, but in the form of 2 employment contracts. An initial 1,5 year contract with an official go/no go progress assessment within 15 months. Followed by an additional contract for the remaining 2,5 years assuming everything goes well and performance requirements are met. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities, increasing from €3059 - €3881 gross per month, from the first year to the fourth year based on a fulltime contract (38 hours), plus 8% holiday allowance and an end-of-year bonus of 8.3%. As a PhD candidate you will be enrolled in the TU Delft Graduate School. The TU Delft Graduate School provides an inspiring research environment with an excellent team of supervisors, academic staff and a mentor. The Doctoral Education Programme is aimed at developing your transferable, discipline-related and research skills. The TU Delft offers a customisable compensation package, discounts on health insurance, and a monthly work costs contribution. Flexible work schedules can be arranged. Will you need to relocate to the Netherlands for this job? TU Delft is committed to make your move as smooth as possible! The HR unit, Coming to Delft Service , offers information on their website to help you prepare your relocation. In addition, Coming to Delft Service organises events to help you settle in the Netherlands, and expand your (social) network in Delft. A Dual Career Programme is available, to support your accompanying partner with their job search in the Netherlands.

Working at TU Delft means contributing to solutions that really make a difference. For over 180 years, we have been training engineers who make an impact worldwide in companies, government bodies, or as entrepreneurs. Our alumni turn knowledge into concrete solutions for the challenges of today and tomorrow. These challenges are changing rapidly. That is why we focus on themes such as energy, climate, digitalisation, artificial intelligence (AI), and smart mobility every day. Our education and research are directly aligned with what society needs now and in the future. At TU Delft, our people make the difference. With their knowledge and curiosity, our staff provide a high-quality education and conduct pioneering research that extends beyond the campus. You will have the opportunity to take the initiative, work with others, and grow as a professional. Working at TU Delft means join an international community of professionals and students. Together, we create knowledge, innovations, and solutions that help move the world forward.

With more than 1,100 employees, including 150 pioneering principal investigators, as well as a population of about 3,600 passionate students, the Faculty of Applied Sciences is an inspiring scientific ecosystem. Focusing on key enabling technologies, such as quantum- and nanotechnology, photonics, biotechnology, synthetic biology and materials for energy storage and conversion, our faculty aims to provide solutions to important problems of the 21st century. To that end, we educate innovative students in broad Bachelor's and specialist Master's programmes with a strong research component. Our scientists conduct ground-breaking fundamental and applied research in the fields of Life and Health Science & Technology, Nanoscience, Chemical Engineering, Radiation Science & Technology, and Engineering Physics.
