Taking it to the bank: Dozens clean up litter along Winnipeg's Assiniboine River

Taking it to the bank: Dozens clean up litter along Winnipeg's Assiniboine River

The banks of Winnipeg's Assiniboine River are a little bit cleaner after dozens of people helped pick up litter near Assiniboine Park on Saturday afternoon. The effort was part of the Great Canadian Shoreline Cleanup, a long-standing national conservation initiative that teaches people about the harmful effects of shoreline and riverbank litter and encourages them to get involved in stopping it. Marc Brandson, curator of animal care at the Assiniboine Park Zoo in Winnipeg, said the group focused on cleaning up any waste found along the banks of the Assiniboine that might eventually find its way into the river system.

How liquid salt could be the answer to oilsands tailings ponds

How liquid salt could be the answer to oilsands tailings ponds

Wastewater from oilsands mining operations have long been a challenge for Canada's energy industry, much of it ending up in industrial tailings ponds. But scientists and engineers at the University of Calgary are taking aim at eliminating watery tailings from the oilsands production process with the help of specialized liquid salt. Hot water is used in oilsands mining operations to extract the oily bitumen from the sand, with the resulting wastewater ending up in tailings ponds to settle and later be reused. Alberta has an estimated 1.3 trillion litres of fluid tailings sitting in tailings ponds.
