Carbon-negative biochar augmented concrete
Biochar makes concrete stronger and more watertight
“1 tonne biochar can trap 2.0-2.6 tonnes of CO2” It is well-established that the concrete industry and use of cement is one of the most emission-intensive industrial processes on Earth. Concrete is the most widely used human-made material on the planet shaping most of the built environment; however, it also has an immense carbon footprint. […]
A team of researchers from the National University of Singapore (NUS) has developed a novel new method to recycle wood waste [as biochar] by incorporating it into cement and mortar mixtures, making the resulting materials both stronger and more watertight.
