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?

Paving, Site Improvements, & Planting—Yes. Irrigation & Constructed Wetlands—No. LEED-2009 limits MR Credit materials to those specified in CSI MasterFormat 2004 Divisions 03-10, Foundations Sections 316000-316999, Paving Sections 321000-321999, Site Improvement Sections 323000-323999, and Planting Sections 329000-329999. This is a change since LEEDv2.2, which used an older version of MasterFormat and included irrigation and site utilities.
