ClearCharacterization of Energy-Relevant Liquid Products from Vacuum Pyrolysis of HDPE Microplastic
Billions of tonnes of plastic waste, including HDPE microplastics, could potentially be converted back into liquid fuels through a process called pyrolysis. This study tested vacuum pyrolysis of HDPE microplastics at 550°C and characterized the resulting oil, finding it is dominated by alkanes and alkenes similar to light petroleum — suggesting real potential as an alternative fuel or chemical feedstock. While plastic-to-fuel pyrolysis is not a complete solution to the microplastics crisis, this work contributes to understanding the technical feasibility of one pathway for recovering value from plastic waste.
Analytical Methods and Devices for Bioenergy and Global Change Science
This thesis describes analytical methods and devices for studying global change processes including carbon dioxide emissions and microplastic pollution, connecting multiple environmental challenges through their measurement and monitoring needs. Developing better measurement tools is foundational to understanding and addressing microplastic contamination.
Combined use of vibrational spectroscopy and mass spectrometry techniques for the study of manuscripts and painted surfaces
This is a doctoral thesis focused on analytical chemistry methods for studying historical manuscripts and painted surfaces, not a microplastics research paper; microplastics appear only briefly as a minor biomonitoring application in a heritage-site survey, not as the primary subject.

Microplastics in the environment and the analysis: fulfil knowledge gap of research size covering, methodology and analytical technologies
This PhD study addresses knowledge gaps in microplastic research by developing improved methods for detecting small microplastics (below 200 µm) and working to harmonize analytical approaches, enabling more consistent comparisons of microplastic data across environments and studies.
The Rock‐Eval Method
This paper is not directly about microplastics; it introduces the Rock-Eval thermal analysis method, which was originally developed for characterising oil source rocks but is now also applied to characterise microplastics and monitor environmental pollution remediation, among other emerging uses.
A New Chemometric Approach for Automatic Identification of Microplastics from Environmental Compartments Based on FT-IR Spectroscopy
