CI-2009 MRc4: Recycled Content
Hi,
I'm working on LEED CI project, which has used products such as panels which are made of steel (20%) which has reycled content (50%) and particle board (80%) which is FSC certified(100%). I wanted to check if I can use this poduct in both MR c4 and MR c7credits?
Thanks

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

Méabh, you can use this content for MRc4, for only "new wood" is applicable to MRc7, not recycled wood.

Thanks Tristan, but my query is regarding a product(panel) that is made of new wood and steel. The new wood in the panel has FSC-certified board at its core. The steel casing part of the panel has reycled content in it. Can this product contribute to both credits?
Thanks

Yes but the only the percentage by weight of the wood will count towards MRcc7. See the equation on pg 397 of the Reference Guide.

Thanks for the clarification Susan, my confusion arose from the birds eye view description for this credit where is says "Materials used to earn this credit cannot also be counted for MRc3: Materials Reuse, nor for MRc7: Certified Wood,"
