FAQs about MRc3 :

The credit language says “Products meeting recycled content criteria are valued at 100% of their cost for the purposes of credit achievement calculation.” How much recycled content has to be in a product for 100% of its cost to count toward credit achieve

Is there any way around the requirement that no more than 30% of the materials used to meet Option 2 be structure and enclosure items?

If Sustainable Agricultural Network (SAN) certification isn’t required for agricultural products to comply with Option 2, does the manufacturer still have to provide documentation of third-party verification?

For the manufacturer “take-back” pathway under Option 2, does the extended producer responsibility program have to be run by the manufacturer?

Are there other ways the products can contribute to Option 1?

Can Corporate Sustainability Reports from the manufacturers of the products I’ve selected help me achieve the Option 1 point for “raw material source and extraction reporting?”

Post-industrial and pre-consumer

Hi all,

On some product documentations, the manufacturer has listed 'post-consumer and post-industrial' recycled content. Can we assume post-industrial to be the same as pre-consumer or does it depend on product type? Note- this is TPO roofing that I am specifically interested in.

Thanks,

Kavita

Yes, post-industrial is the same as pre-consumer. From the LEED glossary - preconsumer recycled content: matter diverted from the waste stream during the manufacturing process, determined as the percentage of material, by weight. Examples include planer shavings, sawdust, bagasse, walnut shells, culls, trimmed materials, overissue publications, and obsolete inventories. The designation excludes rework, regrind, or scrap materials capable of being reclaimed within the same process that generated them (ISO 14021). Formerly known as postindustrial content.
