A college graduate by the name of Kukbong Kim has come up with an incredible new formula for indoor and outdoor paint made of recycled concrete. The amazing thing about this new paint is that it actually has two major benefits for the environment.

Firstly, it uses discarded concrete from the construction industry, which otherwise would end up at a landfill site. This has negative effects on soil pH levels, making them a lot more alkaline and limiting the ability to reclaim landfill sites.

Secondly, the paint is capable of absorbing up to 20% of its weight in CO2. Now imagine if this kind of paint made it onto all the walls and how much that could impact atmospheric CO2 levels.

DeZeen has reported some interesting facts about carbon capture capabilities.

“Cement is the most carbon-intensive ingredient in concrete and is responsible for eight per cent of global emissions. But when concrete is recycled, only the aggregate is reused while the cement binder is pulverised to create waste concrete powder and sent to landfill, where it can disturb the pH balance of the surrounding soil.”

And here’s the interesting thing about this story. If a college graduate can come up with such an idea for paint, what other construction and household materials could be coming our way that will achieve the same thing?
