A Cherished Legacy
Denis Randall – Former Chief Technical Officer

From little things, big things grow. This has certainly been the case with GDT and its Destructive Distillation process, which was built and developed on the dedication of an Australian named Denis Randall, who was GDT’s Chief Technical Officer (CTO).
Denis was a passionate inventor of waste-to-energy and renewable energy technologies. He invented and refined GDT’s Destructive Distillation technology, based on thirty years of practical research.
Denis started his career while obtaining degrees in Metallurgy, Mathematics, and Chemistry, plus a doctorate in the Biodegradation of Subsurface Phenols. After leaving school, he secured a scholarship from BHP. After obtaining a BSc in Chemistry, he switched to Metallurgy where he also obtained a BSc. He moved to Southeast Asia and worked in the petrochemical and palm oil industries in Indonesia, Singapore and Malaysia for the next 35 years. He was awarded a PhD in microbiology from the University of Virginia while he was working with Conico.
His development of the Destructive Distillation process began during his work in Indonesia over a 15-year period. He then returned to Australia and was working on wood-to-gas technology (as well as converting agricultural waste to oil) when he was first asked if he could convert old car tyres to oil and carbon.
Denis put his broad experience to work – and the rest, as they say, is history.
GDT’s technology has been diligently recorded and stored for posterity. After his passing in 2022, this is the legacy Denis Randall has left behind, which we at GDT will always cherish.
