Most people wouldnât guess it, but concrete is the single most widely used material in the world. And both production and consumption are on the rise. The amount of energy used to produce all of this concrete is mind-numbing, as is its impact on the climate. This weekâs guest on Sea Change Radio is Brent Constantz, the founder of Blue Planet, a company that has developed innovative carbon-capturing methods for concrete production. We discuss Blue Planetâs latest projects, look at the industry as a whole, and examine some encouraging concrete recycling solutions.
