How can we reduce concrete’s hefty carbon footprint? Ensia

Yet another way to reduce the carbon footprint of concrete is to recycle it. Researchers at the University of Notre Dame are developing a cost-effective method by which producers of precast concrete — concrete formed into a mold and brought to building sites — can effectively recycle their waste concrete

How can we reduce concrete's hefty environmental footprint ...

27/04/2016  Production of cement — and by extension, concrete — has a large environmental footprint, mostly due to the huge amount of energy it takes to heat limestone, cement’s key ingredient, and the subsequent chemical process it undergoes. The process of creating cement emits upwards of 80 per cent of the cement’s weight

Environmental impact of concrete - Wikipedia

Carbon dioxide emissions and climate change. The cement industry is one of the two largest producers of carbon dioxide (CO 2), creating up to 8% of worldwide man-made emissions of this gas, of which 50% is from the chemical process and 40% from burning fuel. The CO 2 produced for the manufacture of structural concrete (using ~14% cement) is estimated at 410 kg/m 3 (~180 kg/tonne @ density of 2 ...
