| Environmental remarks | Environmental data for the production of 1 kg crude steel from SPIN. Transport is added. The coal comes for 65% from Canada, 23% Australia, 12% from the EEC. Iron ore comes for 37% from Brasil, 21% Australia, 31% Europe and the remaining 11% from elsewhere. Lime is imported from Belgium. Metallic alloy elements are assumed to be added in the required percetages. For details on the winning and refining of the elements see [Metallic Elements]. The production and emission data are for 1989. | |

Last november was a memorable month for us at Matbase, we passed the milestone of 1000 visitors per day. So I guess we were not that far of when we thought it would be a good idea to make the material database we used as students during our stay at the Delft University of Technology accessable to other people. Apparently, people appreciate the easy way they can lookup the material properties and how we present the data.
