I can't seem to find a minimum threshold for the amount of reused / salvaged materials required to be able to achieve all (4) points within Opt 2 Path 4.
Does anyone know if GBCI has internal thresholds they require of project teams?

Hi David,
There is no threshold at present. Since LEED v4.1 is a beta rating system, the intent is to see what types of projects we get so that we can review and see if a threshold is appropriate. I hope this helps.

Does slag count as a reused or recycled material since it is a by-product of steel manufacturing? We have achieved a substantial reduction in GWP in concrete mixes by replacing cement with slag, and are hoping to achieve the 4th point in version 4.1

Would be interested to hear if there is an answer to Rachel's question? i.e. could cement replacement count as salvaged material?

To be considered "salvaged" I believe it needs to be recovered from an existing building or construction site. By-products of a manufacturing process are considered "pre-consumer recycled content". It is my understanding that slag would probably more closely align with a pre-consumer recycled content product.
