Polyolefins are the largest class of commodity polymers. Polyethylene and polypropylene are the most common commercial types of these polymers. The former accounts for nearly one-third of the world polymer market and it is predicted that its demand will keep growing in the foreseeable future....

Oil spills are a worldwide concern that threaten the environment, ecosystems, human health, and economy. Conventional methods to combat oil spills, such as in-situ burning, booms and skimmers, dispersants, and biodegradation are not effective enough. A more efficient technology is needed to...

Emulsion Polymerization of Poly-(Methyl Acrylate) for Flocculation and Dewatering of Oil Sands Tailings.
DownloadFall 2020
This work adds to the continuing research efforts in Alberta to manage the accumulation of oil sands tailings and reduce the environmental footprint of oil sands’ operations. Oil sands tailings are unwanted by-products of surface-mining bitumen extraction processes. They are usually held in...

Morphological Effects of Water Soluble Polymer Flocculants Synthesized by Controlled Reversible-Deactivation Radical Polymerization for Treatment of Mature Fine Tailings
DownloadFall 2020
The bitumen reserves in Northern Alberta are a valuable asset, but extracting bitumen from oil sands via the Clark hot water process produces undesirable waste tailings. These tailings are transported to tailings ponds where the sand and clay particles are left to settle slowly, creating a...

Oilsands tailings are a waste product comprising primarily a stable alkaline suspension of clay in water. This waste product of oilsands mining is environmentally hazardous to store and expensive to safely dispose of. This work presents two novel ideas for dealing with the waste. The first is...

Spring 2020
Near one billion cubic meters tailings have been released to the environment as the result of oil sands mining operations in Canada. These fluid fine tailings are alkaline slurries of water, clays, and residual bitumen that after 3 to 5 years of gradual sedimentation form a thick mud-like slurry...

Spring 2023
The extraction of bitumen from oil sands is an energy and water-intensive process that produces a tailings byproduct containing sands, clays, water, and residual bitumen. Larger particles eventually settle out of the tailings, but fine particles – stabilized by the residual bitumen – remain...
