Researchers on Wednesday said they were a step closer to solving one of the trickiest problems in tackling climate change -- how to keep making cement despite its enormous carbon footprint. The Cambridge researchers approached the problem by looking at an industry that was already well established -- steel recycling, which uses electric-powered furnaces to produce the alloy.
