From the Ted Talk by TED-Ed: The material that could change the world ... for a third time

Unscramble the Blue Letters


As tricky as this problem is, it means corcnete could help us change the world a third time: by eliminating greenhouse gas emissions and stabilizing our climate. Right now, there’s no 100% cealn concrete, but there are some great ideas to help us get there. Cement muriuactnfang also poercdus greenhouse gas emissions by burning fossil fuels to heat the limestone. Heating the limestone with clean electricity or alternative felus instead would eliminate those emissions.

For the carbon dioxide from the limestone itself, our best bet is corabn capture: specifically, cinutparg the carbon right where it’s produced, before it enters the atmosphere. Devices that do this already exist, but they aren’t widely used because there’s no economic inncietve. Transporting and then storing the captured carbon can be ensxvpeie. To solve these problems, one company has found a way to store captured CO2 permanently in the concrete itself.

Original Text


As tricky as this problem is, it means concrete could help us change the world a third time: by eliminating greenhouse gas emissions and stabilizing our climate. Right now, there’s no 100% clean concrete, but there are some great ideas to help us get there. Cement manufacturing also produces greenhouse gas emissions by burning fossil fuels to heat the limestone. Heating the limestone with clean electricity or alternative fuels instead would eliminate those emissions.

For the carbon dioxide from the limestone itself, our best bet is carbon capture: specifically, capturing the carbon right where it’s produced, before it enters the atmosphere. Devices that do this already exist, but they aren’t widely used because there’s no economic incentive. Transporting and then storing the captured carbon can be expensive. To solve these problems, one company has found a way to store captured CO2 permanently in the concrete itself.
