FAQs about MRc4 :

I have recycled content information for a product, but it doesn’t specify whether it is pre-consumer or post-consumer. What should I do?

The recycled content percentage on the product data sheet is given as a range. What should I do?

The manufacturer can't give me product-specific recycled content data, but they say that they fall within the national industry average. Can I use that?

Is the default average recycled content value of 25% for steel still allowed?

Can site materials, such as soil, be included in the MR credit calculations?

Are there recycled content claims that I should be wary of?

Can I count FSC-certified MDF toward both MRc4 and MRc7?

If I have one cut sheet that meets the LEED 2009 requirement to upload 20% of cut sheets by cost, for this credit, is that acceptable?

Schools-2009 MRc4:Recycled Content

Rebar

I have a question about tracking the recycled content for rebar. Considering the various metal components included in rebar, can you include letters from all relevant manufacturers with their percentages of recycled content and then use the lowest percentage for the line item for the formula? I know there is the default percentages, however, on average the various percentages are in the 90s. Thanks for any advice. Nell

Nell, I am a little confused on whether you are talking about rebar from different suppliers, or different metals included in rebar. If the latter, it seems more complicated to me, more math involved--if the former, your approach sounds reasonable.

Hi Tristan, Thanks for following up. It's one manufacturer, but the steel mill source includes two different companies with different recycled content values for the steel. Would it still be reasonable and acceptable for LEED for this credit to take the lower of the two? Thanks so much, Nell
