Environmental Remediation

Science and practice behind why bioaugmentation accelerates the remediation of chlorinated solvents in groundwater

Prof. Elizabeth Edwards (U of T)

Dr. Elizabeth Edwards is a Professor in the Dept. of Chemical Engineering and Applied Chemistry at the University of Toronto and is also the Director of BioZone which is a Centre for Applied Science and Bio Engineering Research within the Faculty of Applied Science and Engineering. The focus of Professor Edwards’ work is to harness and en­hance the innate ability of anaerobic microbes to biologi­cally transform common toxic pollutants or to convert waste products to more valuable products. She has been involved in the release of a commercially successful bioproduct which biodegrades common industrial groundwater pollutants more quickly and at a lower cost than conventional methods.  Professor. Edwards’ work also involves working on anaerobic digestion of municipal organic wastes with tremendous potential to address the environmental pressures facing most industries and municipalities.

Cleaning-up Mining Industry Wastes: The Social, Environmental and Economic Benefits

Paul Miller (BacTech Environmental)

Paul has a doctorate in chemical engineering and is a chartered engineer by profession with extensive knowledge and practical experience of mining and metal extraction acquired over a career span of 40 years. He has held senior positions within mining companies as Vice President of Technology and Engineering, and is also a recognized expert in applying bioleach processing for treatment of difficult ore types. Bioleaching Technology is used in minerals processing as an environmentally responsible and economic alternative to roasting or smelting for treating a variety of commodities. Projects are now underway by BacTech Environmental Corporation to apply their proprietary bioleaching technology to clean up toxic mine waste, in which the residual metal values present in mine
waste are recovered and sold to create project value, while toxic elements, such as arsenic, are stabilised as benign residues. The talk will focus on the technology and business approach used by BacTech to create this world-wide contribution to sustainability in cleaning-up mine sites in a profitable manner, which has both social economic and environmental benefits.
