Tailings to the rescue

摘要

In order to avoid an increase of the global temperature by two and half degrees by 2100, the scientific consensus is that society must achieve net negative emissions - in other words, pull more planet-warming carbon dioxide (C02) from the air than we produce. According to University of British Columbia Bradshaw Initiative for Minerals and Mining professor Greg Dipple, the mining industry could become a major player in helping society achieve this goal. For over a decade, he has been researching a process in which tailings waste naturally draws C02 from the air and traps it into new stone formations.
