Research Interests

Green technology Laboratory
The research in the Green Technologies Research Group applies sciences (e.g., chemistry and mathematics) and engineering principles (e.g., transport phenomena) to address environmental problems related to sustainable energy. Our projects address global issues such as clean air, clean water and climate change. Through our efforts, new technologies are developed for minimizing industrial emissions while maximizing the values of natural resources. We also seek to understand the fate, transport and impacts of pollutants in the natural environment.

In the past few years, we’ve worked on a series of problems related to applied sulphur chemistry – a foundation of our research program, including the properties of sulphurous acid as a leaching agent to selectively extract valuable metals from non-ferrous metal smelter slag and to reduce the leaching potential of metals in the slag. Recently, our group initiated a study on the carbothermal reduction of sulphur dioxide (an air pollutant) using petroleum coke, a byproduct of upgrading bitumen to synthetic crude oil that is being produced and stockpiled in large quantities (over 50 million tonnes) in Alberta. Our work on oil sand petroleum coke directly addresses the environmental issues associated with the oil sands industry, such as water quality and consumption and air quality.

While most pollutants are generated locally, they can travel and become global in scale. A better understanding of pollutant behaviour in the environment is essential to the protection of the natural environment. In collaboration with Environment Canada, our group’s research on the effects of aerosols on climate change contributes to a more accurate assessment of the issue, particularly global warming, and helps researchers to devise a strategy to deal with the challenge.
