Dr Kameron Dunn is a Senior Research Fellow in the QUT Centre for Agriculture and the Bioeconomy (CAB) and has worked within an R&D and consulting environment for over twenty-two years. Dr Dunn is a subject matter expert for sugar milling process modelling and technoeconomic assessments associated with cogeneration and sugar industry product diversification. Dr Dunn’s consultancies typically include biomass utilisation and biofuel scoping studies, technical audits of sugar factories, energy efficiency optimisation, design of process equipment and process modelling.
In 2009, Dr Dunn was awarded an industry PhD scholarship from the Sugar Research Development Cooperation (SRDC) for a thesis titled "Conversion of sugarcane lignin into aromatic products and the fractionation of products for industrial use", which received a QUT 2014 Outstanding Doctoral Thesis Award (Executive Dean’s Commendation Award). In 2016 Dr Dunn was awarded an Advanced Queensland Fellowship by the Queensland State Government to continue an R&D focus on transforming waste products via the thermochemical technologies, hydrothermal liquefaction and pyrolysis, to minimise and transform agricultural, petrochemical derived and sewage waste feedstocks, into value-adding products. The Fellowship project also advanced recovery and fractionation of derived products via supercritical fluid techniques. The research is now used to drive the diversification of renewable biomass (lignin) into biocrudes, chemicals, phenolic resins, nutraceuticals, sugarcane lignin thermoplastics, carbon products (fibre and composites) and ceramic research.
During 2020 Dr Dunn was elected as a Chartered Chemical Engineer from the Institution of Chemical Engineers and received Registered Professional Engineering in Queensland (RPEQ) certification.
In 2021/2022 Dr Dunn is supporting the engineering upgrades at QUT's existing Mackay Biocommodities Pilot Plant Facility, to enhance the facilities capability in biomass processing, fermentation and downstream processing, and to develop the technologies and products in these growth areas that improve upon current capability that support research in synthetic biology, future foods, biomaterials, food and feed supplements, biofuels and biochemicals. In addition, in 2022 Dr Dunn is supporting efforts at QUT to commission, develop and demonstrate mineral processing and refinement capacity at pilot scale at the Redlands Research Facility.
