Our research partnership is international in scope involving companies and researchers in Canada, the United States, Finland, Sweden, Brazil, New Zealand, and United Kingdom.

Most industrial plants, especially those in the pulp and paper, steel, mining, petroleum and tar sand industries, require large amounts of power, high pressure steam, water and chemicals to operate. Effective utilization, generation and regeneration of these essentials are of vital importance to the productivity, economy and environmental sustainability of the plants. Our “Energy & Chemical Recovery” research has evolved greatly since its initiation in 1987. The goals have been to obtain fundamental information on the equipment and process involved, and to use the information to develop viable technologies/strategies to increase the energy production and chemical recovery efficiencies of the process, particularly that in the pulp and paper industry. Over the years, we have successfully conducted ten industrial research consortia on problems encountered in kraft pulp mills. Our current research activities are in three main areas: energy and chemical recovery in the kraft pulping process, alternative fuels for lime kilns, and combustion characteristics of biomass and mixed fuels. These fields of research are interdisciplinary, involving chemical engineering, combustion, reaction kinetics, heat transfer, fluid mechanics, computer modelling (thermodynamic, dynamic and CFD), and bioengineering. There are presently over 30 researchers involved in the research program including 15 graduate students, 5 research staff and 12 professors in the Department of Chemical Engineering and Applied Chemistry, the Department of Mechanical Engineering and Industrial Engineering, and the Pulp & Paper Centre at the University of Toronto. Students often have opportunities to visit plants, conduct field trials, present their work at industrial meetings and conferences, and interact directly with other faculty and industry on problems of economic and social importance.
