NUS Engineers Repurpose Excavation Waste to Produce Greener, Stronger Concrete

NUS researchers have taken a waste product from construction sites in Singapore and upcycled it into a raw material for ultra-high-performance concrete. Their method could help reduce the carbon footprint of concrete and also cut the cost of production. This is the first time low-grade waste clay has been used as fillers in concrete.

Building cities with wood would store half of cement industry’s current carbon emissions

Shifting to wood as a building construction material would significantly reduce the environmental impact of building construction. If 80% of new residential buildings in Europe were made of wood inside and out, they would store the equivalent of about half of the cement industry’s annual emissions.
