13. Using Polymer Reaction Engineering Principles to Help the Environment: The Case of the Canadian Oil Sands Tailings
The Canadian oil sands reserves are an important national resource with a large impact on the Canadian economy. Unfortunately, oil sands extraction processes generate toxic by-products called mature fine tailings that need to be stored in disposal ponds for a very long time before the land can be reclaimed. This serious environmental liability needs to be ad
