Sunlight-activated nanoparticles could clean up oil sands pollution on the cheap

Researchers say they have found a cheap and practical way to treat polluted oil sands wastewater

Last year around 2.3 million barrels of oil were pulled each day from tar sands in Alberta, Canada, the third largest oil reserve in the world. This mining process is hugely water-intensive, and though much of it is recycled, it still results in massive pools of polluted wastewater which are difficult to treat and pose a threat to the environment. Canadian researchers have developed a new approach to removing the contaminants using sunlight and nanoparticles, an approach they say will prove much more effective and cheaper than existing methods.
