This Concrete-Eating Robot Can Recycle An Entire Building On The Spot

Knocking down a concrete building usually takes brute force: Wrecking balls, huge excavators, or explosives rip apart walls while fire hoses spray water to keep the clouds of dust down. It’s an energy-intensive process, and after everything’s been torn apart, the concrete often ends up in a landfill or has to be trucked to a recycling facility. But a new concrete-erasing robot may eventually transform the messy business of demolition.
