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.

I realize that actual material invoices are not required for upload, but I am on a project right now where many of the subs are giving me a percentage of the contract amount.

What is the % of recycled content steel rebar needs to have to qualify to get the MR credit on recycled content?

Hi, I have read the LEED requirements and comments regarding the exclusion of things like glass and aluminum scrap that are reincorporated into the same manufacturing process.

The LEED online V3 form of MR Cr 4 requires to type item by item sustainable materials on the form while V4 form requires only to upload material calculator worksheet and then type the total cost

Hej! Do ready made concrete elements that are delivered on site count as assembly while in concrete that is cast on site the concrete and steel are two materials? Thanks!

Can anybody suggest way of reuse of concrete generated from slump cone test of concrete and its debries to be reused with in the project site.

I accidentally posted this in the Certified Wood section...If I take the default 45% of contract price for divisions 3-10 just in the concrete and steel my totals are 80% plus for recycled content

I've just learned of a company that remediates contaminated soil and aggregate and then sells the material (for cheaper than virgin material).

Three question regarding recycled content in concrete: *If the concrete contains brick chips from reused bricks will it count towards recycled content.
