As the globe ’s cities amplify at faster and quick speeds , so does its use of cementum . Oneoft - quoted statisticshows that China alone used as much cementum in the last three years as the US used in the last 100 . Just one job : Cement is responsible for pushing a hell of a lot of carbon dioxide into the man .
The process of realize cement is imagination - intensive and heat - intensive — that ’s why it creates so much CO2 . And that ’s why research worker are concerned in finding manner to trap or sequester that CO2 , and why the inquiry project of a University of Arizona student in the early 2000s is collect so much interest . Arecent PBS reportintroduced us to Stone — now Ph . D — whose product was made in a science laboratory by stroke , while he was experimenting with iron :
It was bubbling and spitting . And I thought , well , that — that did n’t puzzle out . The next twenty-four hour period , when I come in and I chance it and rescued it from the scraps , I realize , this just did n’t get hard . It make very arduous , glassy hard .
For the past 13 years , he ’s built a business around the glassy stuff he calls Ferrock . It ’s made from the waste of brand John Stuart Mill ( steel dust ) and does n’t practice the same heat - intensive production process of cement . It ’s also more long-lasting and stronger than cement .
But that ’s not actually braggart merchandising item . That would be the fact that this potpourri of chemical actually sucks up CO2 and ensnare it , asUniversity of Arizona explains :
Conversely Ferrock ™ only hardens when scupper to high concentrations of carbon copy dioxide , which is take in and trapped , making it a carbon negative material . This greenhouse gas diffuse into the wet mix and reacts with the iron , create branding iron carbonate and becoming part of the material ’s mineral matrix .
Sounds great , right ? What ’s stopping the world from take up Ferrock to supplant cement ? Well , making a monolithic epitome shift in one of the large industries on Earth is n’t as easy as demonstrating a breakthrough . We ’re speak about an industry that accounts for as much as$250 billion in profitsa year . Check out the fullPBS mini - Commerce Department above for more .
