MIT researchers find a way to eliminate carbon emissions from cement production — a major global source of greenhouse gases. The process involves using an electrochemical process, instead of fossil-fuels. Although the process is cost-effective, easier to scale, and an overall cleaner option, breaking into an already established industry has been a huge challenge. The approach is to replace portions of the industry over time, and try not to overhaul all at once.
