John began his career in 1982 in heavy industrial engineering design leading to project management and department head with prestigious design and construction and consulting organisations including John Holland, Maunsell, Parsons Brinkerhoff, Minenco, Clough and Kinhill. He formed his own engineering design and construction consultancy in Australia known as The Project Office in 1988. TPO has completed more than 300 significant projects to date in almost every industry including mining, petrochemical, military, manufacturing, energy, water treatment, pharmaceutical, aquaculture and agriculture. TPO has designed, constructed, and supported every major algae farm and processing plant in Australia. In 2006 John created an organisation known as Enesys to specifically apply the capabilities with high-end control systems found in large industry to create novel and sustainable links between waste, energy and agriculture (enabling circular economies).
Johns broad engineering background involving detailed electrical, mechanical and process control design enables him to bridge technical gaps between disciplines and create innovative technical and economic links. He applies computer modelling to every repeatable component of engineering and economic design and more recently linked these models to create extensive Waste to Energy to Growing models called Enesys WEG. Enesys WEG technically and economically demonstrates the ability to create energy and resources from almost any waste and divert those resources to grow fruit and vegetables or to aquaculture.
