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. However, I am unclear if this exception applies to a project I am currently working on.
I am working with a client whose family owns and operates a granite countertop fabrication shop. The process currently generates a lot of scrap pieces that are too small for countertops and are therefore currently being thrown out as garbage. Our client is interested in starting a separate company in which she would use the granite countertop scrap pieces to create different granite product lines (i.e. granite tiles for floor or backsplash) instead of them just being thrown out. Although it would be a separate company creating a different product line, the same fabrication shop and tools would be used for both the countertop pieces and the tile pieces. Eventually she would like to collect and incorporate scrap granite pieces (that would otherwise be thrown out) from other countertop fabrication shops as well.
My question is this: Would the proposed tile products made from the countertop scrap be considered as containing recycled content that would contribute to the achievement of LEED credits, since the scrap is currently being thrown out? Or would this be disqualified since it would just be using the same equipment to fabricate smaller pieces?
Thank you in advance!

Jay - In the scenario you describe I would interpret the countertop scrap being cut into tiles as having 100% pre-consumer recycled content. LEED defines preconsumer recycled material as 'diverted from the waste stream during the manufacturing process.'
I do not think the exclusion for reutilization would apply because your client would be processing the scrap into a product different from the one that produced it.

Jay - Please know that this forum is not a definitive source for answers as to what GBCI will and won't accept. That said, I think Joseph answered your question with the same information that I would convey - this would be pre-consumer material and since the end product is something different than the original product, the issue of reutilization should not come into play.
On another note, make sure your client is aware of LEED v4 changes to the M&R category and understands the impact of MRc4: Recycled Content being part of Building Product and Disclosure and Optimization - Sourcing of Raw Materials - http://www.usgbc.org/leed/v4.

Joseph and Michelle,
Thanks for the info and for sharing your feedback with me. I apologize if I should have worded my question better...I am aware this is not a definitive source as to what GBCI will or won't accept, but I was hoping to see if anyone else had experience with a similar situation or had an opinion on the matter.
Thanks again.
