A lot of steel manufactures are providing a "LEED" letter that includes both recycled content values for Electric Arc Furnance (EAF) and Basic Oxygen Furnance (BOF) method of producing steel. If they don't state which was was used for the steel on our project, do I have to ask them to tell me which method was used for the steel on our project and if they don't know should I use BOF, which always has significantly less recycled content than EAF? Is one method more common than another? Also, I am seeing a lot of steel suppliers state that they recover approx. "95-100% of the steel scrap within 500 miles" from their facility. In this case, the only way around this is we would need them to provide an actual location in order to count as regional material, correct? Thanks!
