To reduce carbon emissions from cement manufacturing, emission-heavy steps of the process can be replaced with alternative techniques. Researchers from the Massachusetts Institute of Technology experimented with using electrolysis to create cement and found that in addition to reducing carbon emissions, byproducts from the process can be reused.
