Canada’s response to President Barack Obama’s challenge to reduce emissions of global-warming gases from the oil sands starts with sewage and algae.
The paste-like crude extracted from oil sands is softened by heat and steam to make it flow though pipelines. Burning natural gas to process the fuel creates carbon dioxide that researchers say can be mixed with waste water and fed to algae, which can be processed into cattle feed and other products.
