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.

Harmful Microbes Found on Sewer Pipe Walls

Can antibiotic-resistant bacteria escape from sewers into waterways and cause a disease outbreak? A new Rutgers study, published in the journal Environmental Science: Water Research & Technology, examined the microbe-laden “biofilms” that cling to sewer walls, and even built a simulated sewer to study the germs that survive within.

‘Nature’s antifreeze’ provides formula for more durable concrete

Secrets to cementing the sustainability of our future infrastructure may come from nature, such as proteins that keep plants and animals from freezing in extremely cold conditions. CU Boulder researchers have discovered that a synthetic molecule based on natural antifreeze proteins minimizes freeze-thaw damage and increases the strength and durability of concrete, improving the longevity of new infrastructure and decreasing carbon emissions over its lifetime.
