Enjoying a settled academic position in a highly dynamic and successful department, I define my research and teaching interests by the multiple challenges of sustainable development in developing country settings, esp. as these pertain to resource flows. My interests span topics in the fields of Environmental Systems Analysis, Renewable Fuels Processing (biogas, biodiesel and bio-ethanol), Waste Management and Sustainable Consumption. Since joining the University of Cape Town in 1998, 42 Masters and 4 PhD students have completed their theses under my supervision, and we have published some 45 papers in peer-reviewed journals. I have taught in 7 different courses in the undergraduate curriculum and have introduced sustainability into the curriculum at both the undergraduate and postgraduate level. In 2009, I led a team that hosted the 4th international Life Cycle Management conference in Cape Town. I currently chair the Voluntary Advisory Forum of South Africa’s Chemical and Allied Industries Association.
From 1995 until May 1998 I was employed at the Chair for Mineral Processing, Beneficiation and Waste Treatment at the Aachen University of Technology in Germany. There, I also completed my doctoral dissertation, in which, I developed an extension of the sampling theory of particulate solids for applications in recycling operations. The doctorate in engineering was awarded summa cum laude in 1999.
With my roots in South Africa's Eastern Cape and in Namibia, I commenced my academic career with a BSc in Chemical Engineering (first class honours) from the University of Cape Town in 1990. After two years as a process engineer on a PVC production plant, I returned to UCT in 1993, obtaining an MSc.Eng. in 1994.

My research interests are inspired by the multiple challenges of sustainable development in the resource industries esp. in developing country settings, and span topics in the fields of Environmental Systems Analysis, Bio-Fuels Processing, and Waste Management. Sustainability in resource processing requires: The closure of substance cycles in the economy, and the minimisation of environmental impacts by wastes and emissions: here I concentrate on the minerals beneficiation industries. The powering of such closed substance cycles by renewable energy: Here I limit myself to work on biofuels. A scientific assessment tool to enable the measurement of progress in complex industrial systems: here I work mainly with environmental Life Cycle Assessment.
