Dr Daniel Gapes is an environmental engineer with an impressive record of developing innovative technologies. He is currently leading Scion’s environmental technology research, aimed at developing new ways of managing and deriving value from organic waste.
- PhD (Chemical Engineering), University of Queensland, Australia - 2003
- Masters of Technology (Hons)(Environmental Engineering), Massey University, New Zealand - 1994
- Bachelor of Chemical Technology (Hons) Massey University, New Zealand -1992
- Bioreaction engineering and environmental biotechnology, with particular emphasis on the development of advanced tools for bioreactor analysis, and the transport and reaction phenomena which occur within such systems.
- Hydrothermal processing for conversion of waste biomass for value-added opportunities.
- Production of valuable materials from waste precursors, with particular emphasis on the bacterial production of polyhydroxyalkanoate biopolymers.
- Research Leader of pilot plant development programme, focussed on hydrothermal processing of waste biomass via wet oxidation technology. This programme targets the identification and design of a new process (TERAX™) for solid waste conversion.
- Responsibility for leading the research direction for the development of new and emergent environmental biotechnologies. Over the last 5-10 years, our group has overseen the development of a patented nitrogen fixation-based biotechnology platforms, including a biopolymer production technology (N ViroPol®)
- Co-inventor of a high-end fermentation research instrument, the TOGA sensor, and leading the technical development of this through a commercialisation stagegating process at Scion. This has attracted co-investment through PSAF, industry and RFI funding to the value of $310K, and has been the subject of a current patent application. To date, two pre-commercial sales have been achieved.
- Responsible for developing and maintaining a key strategic relationship with a number of leading environmental biotechnology research laboratories, including the Department of Biosystems Engineering at the University of Manitoba and the Advanced Water Management Centre at the University of Queensland, Australia. These relationships focus both on fermentation research as well as the commercial development the TOGA sensor.
