Negative Carbon Concrete

The most popular construction material on the planet is concrete and it turns out that the way we use it is not environmentally friendly. What if we changed that?

A company has created a great concrete variation that actually beneficial for the environment as it removes excess carbon!

While it functions much like commonly used Portland cement, boasting the same level of performance and the same average cost, Novacem’s concrete mixture uses magnesium silicate instead of calcium carbonates. The slinging of chemistry jargon might make this seem complicated, but the concept is simple: the creation of magnesium carbonates from magnesium silicates absorbs carbon dioxide. In other words, the production process is carbon negative. Furthermore, the production process of Novacem’s concrete is low-energy, allowing it to be sustained on biomass fuels.

Carbon Cloth to Wipe Away Toxic Stuff

This is a pretty neat reuse of knowledge of material science from one of violence to one of saving the environment. Carbon cloth meant for the battlefield can be used to clean up toxic spills.

The textile is composed of tiny pores that adsorb organic molecules through weak Van der Waals forces. By adding ozone to the process, the fabric becomes even more effective at catalyzing the conversion of unwanted content into smaller molecules—or even carbon dioxide and water. In other words, the activated carbon cloth breaks pollutants down into less-harmful compounds.
