Cape Town is running out of water, but professor Sue Harrison might have a solution. Most bioprocess engineers wear crisp lab coats and work in ultra-clean stainless-steel reactors. While professor Sue Harrison, from the University of Cape Town’s chemical engineering department, is familiar with this sterile world, she’s increasingly drawn to muckier, less controlled environments. For the past 15 years, her focus has been on melding bioprocess engineering skills with nature-mimicking processes to challenge the very definition of waste. Harrison is a pioneer of both bioprocess engineering (putting nature, often in the form of algae or bacteria, to work in industry, cities, businesses and elsewhere) and transdisciplinarity (she’s worked at the interface of chemistry, engineering and the life sciences for more than 30 years). Now, as the director of the Future Water Institute, UCT’s interdisciplinary research center, she is taking both obsessions to their logical extremes in a quest to improve the prognosis for water-starved South Africa, a country that, according to doomsday predictions, could run out of water by 2030. |
