Byproduct Of Steel Shows Potential In Carbon Dioxide Sequestration

Summary:
With steelworks around the world emitting huge amounts of carbon dioxide, scientists are reporting that a byproduct of steel production could be used to absorb that greenhouse gas to help control global warming.

With steelworks around the world emitting huge amounts of carbon dioxide, scientists are reporting that a byproduct of steel production could be used to absorb that greenhouse gas to help control global warming.

Professor Mourad Kharoune and colleagues point out that production of one ton of steel releases up to one ton of CO2. With global steel production standing at 1.34 billion tons in 2007, that adds up to a substantial contribution of carbon dioxide.

Kharoune suggests a new method to sequester, or capture, carbon dioxide so that it does not contribute to global warming – using steel slags, which are complex mixtures of compounds produced during the separation of the molten steel from impurities.

In the study, Kharoune suggests that electric arc furnace (EAF) and ladle furnace (LF) slag suspensions could be used for greenhouse-gas sequestration.

According to the report, the ladle furnace slag suspension's capacity to sequester emissions was 14 times higher than that of the EAF suspension, possibly due to the LF's higher content of a rare mineral called portlandite.

Goma Cheese Brings Whiff of New Hope to DRC

Reuters - Business Video Online (July 24, 2014) The eastern region of the Democratic Republic of Congo, mainly known for conflict and instability, is an unlikely place for the production of fine cheese. But a farm in the village of Masisi, in North Kivu is slowly transforming perceptions of the area. Known simply as Goma cheese, the Congolese version of Dutch gouda has gained popularity through out the region. Ciara Sutton reports. Video provided by Reuters
