Coffee and hydrogen the key to green steel - UNSW

The University of New South Wales (UNSW) has released three research papers showcasing that waste coffee grounds and hydrogen could be used in the fabrication of green steel.

Under its Sustainable Materials Research and Technology (SMaRT) Center, the UNSW published the three papers on its Green Steel Polymer Injection Technology (PIT), noting that industrial trials with partner Molycop have shown various wastes can be used to more sustainably make steel in electric arc furnaces.
