Sweden

Umeå University in Sweden is advertising a 2-year postdoctoral position in Environmental Chemistry at the Department of Chemistry. The project focuses on hydrothermal carbonization (HTC) , especially the recovery of carbon and organic material from HTC filtrates. The successful candidate will study how self-generated carbon (SGC) forms in process water and what filtrate chemistry controls its formation. The work sits within the RE-FIL project, which aims to turn HTC filtrate from a waste stream ...

About this position

This postdoctoral project is based in the Environmental Chemistry group at the Department of Chemistry, Umeå University. The successful researcher will investigate how carbon and organic material can be recovered from hydrothermal carbonization (HTC) filtrates, with a particular focus on the formation of self-generated carbon (SGC)—low-ash carbon microspheres with promising surface and morphological properties for energy storage and environmental uses.

The project examines a practical resource-recovery challenge: while HTC produces a carbon-rich hydrochar from wet residues, much of the carbon remains dissolved in the process water and is typically discarded. Here, the filtrate is treated as a resource rather than waste. The postdoctoral researcher will study what controls SGC formation and how the chemistry of the filtrate shapes the products that form spontaneously.

The work is part of RE-FIL, a broader project that also explores microbial production of biodegradable plastics from the same filtrate stream in collaboration with Karlstad University. A key aspect of the research is therefore the interface between two recovery routes and whether they compete or can be combined. The postdoc will contribute to this by characterizing filtrates and products using chromatographic, spectroscopic, and microscopic techniques.

The position offers access to the Trace Analysis Platform and the Vibrational Spectroscopy Core Facility, within a collaborative and international research environment. The main advisor is Prof. Stina Jansson, with Assoc. Prof. Maria Sandberg of Karlstad University as co-advisor. Some work may be carried out at Karlstad University.

What's required

Applicants must have completed a doctoral degree or equivalent by the appointment decision, preferably within the last three years unless special reasons apply. The doctoral degree should be in chemistry, environmental chemistry, materials chemistry, chemical engineering or a closely related subject. Candidates must have documented experience designing and performing experimental laboratory work in chemistry and using instrumental analytical techniques for chemical or material characterization. Experience with at least one of chromatography–mass spectrometry (e.g. LC-MS/MS, GC-MS), elemental analysis (e.g. ICP-MS), or surface/material characterization (e.g. BET, FTIR, XPS, SEM) is required, and the application should clearly state which techniques were used, for what purpose, and to what extent. Very good spoken and written English is required, along with a documented ability to publish scientific results, normally shown through first-author papers in peer-reviewed international journals. Merits include experience with hydrothermal carbonization or other thermochemical conversion techniques, elevated-temperature/high-pressure experiments, pilot-scale work, surface chemistry, aqueous-phase organic chemistry, and interdisciplinary or international research environments.

How to apply

Prepare a full application in English or Swedish including a cover letter, CV with publication list, verified doctoral degree documentation, other diplomas and grades, and any additional supporting documents. Submit the application through Umeå University’s electronic recruitment system via the application button on the posting page.
