Summary: 

This project focuses on enhancing hydrochar/biochar production for environmental applications, including water remediation and soil improvement, using innovative thermochemical processes like torrefaction and hydrothermal carbonisation (HTC). Char, derived from biomass, has the potential to capture excess nutrients from water bodies, preventing eutrophication, and can later be applied as a soil amendment to improve soil health and crop yields. 

 

The project aims to optimise char production techniques by investigating key factors such as feedstock types, pyrolysis temperatures, and activation agents. It will assess char’s effectiveness in removing nutrients (e.g., nitrogen, phosphorus, potassium) from freshwater and explore its ability to recycle these nutrients into nutrient-deficient soils. A comprehensive techno-economic evaluation will determine the feasibility of scaling up char production for industrial applications. 

In addition to advancing scientific understanding, the project offers comprehensive training opportunities. The PhD student will gain essential skills in engineering, materials science, data analysis, laboratory techniques, and public engagement. They will participate in research seminars, conferences, and public engagement programs while developing teaching and supervision experience. This interdisciplinary project provides a solid foundation for a successful career in research and development within the growing bioeconomy sector.
