South African Invents Green Alternative to Concrete

A thick, grey blanket covers the world’s cities, speeding global climate change. But it isn’t smog. It’s concrete.

Though cities from Houston to Shanghai rely on traditional Portland cement-based concrete, Jannie van Deventer has a better idea — just don’t ask him to tell you the exact details.

He keeps the formula of his Zeobond E-crete secret, but the South African entrepreneur thinks his greener alternative can make a huge impact on a planet where concrete production is responsible for a surprisingly large share of global greenhouse gas emissions.

“We’ve constructed dozens of buildings in Australia and South Africa with Zeobond E-crete,” says van Deventer, “and they’ve all been successes.”
