Green Steel

CSIRO, Australia's national science agency, is working on a way to help industries produce cleaner steel. Their idea is to have steel mills use charcoal produced from trees planted to combat salinity.

The charcoal is much cleaner and burns faster than the coke currently used. Further studies have shown that this process can use 65% less CO2/tonne of iron even when including energy for growing, processing, and transport. A more in-depth exploration of the idea can be found in CSIRO Solve Magazine.
