FAQs about MRc2 :

How is construction waste accounted for when utilizing off-site construction, like modular construction or pre-fabrication of assemblies?

How does MRc2 work for projects pursuing a campus approach, or any project where waste management will be shared with other construction projects?

Can materials that have been unused and returned to the manufacturer as part of a “take-back” program contribute to the credit?

Should I include hazardous material such as lead-based paint in MRc2 calculations?

Should household-type trash from workers' lunches and office use be included in MRc2 diversion and calculations?

Can sending material to waste-to-energy plants count toward MRc2?

The requirements of this credit say that land-clearing debris does not contribute to the percentage of materials diverted from the landfill. What exactly is considered "land clearing debris"?

Oops! Our trash was measured by both weight and volume at different times. How do I standardize this?

The waste management facility we are using is providing us with monthly documentation specific to our waste, showing 80% diversion. They also have a published, facility-wide rate of roughly 20%, and they have no published rate for construction waste. Will

NC-2009 MRc2:Construction Waste Management

Commingled or Source Separated

Could someone please help define the meaning of 'source separated' in terms of the Material Stream credit calculator? The project I'm working on collects all of its recyclable waste in a single container due to site area constraints. The waste is then taken to a recycling facility where it is separated into its constituent components, weighed by material, and recycled accordingly. Are we allowed to claim credit for each of the materials within our commingled load since they are sorted before they are weighed, or is this still considered a single waste stream since it is commingled on the site?

Risto - As I see it, materials streams are part of the LEED v4 version of this credit. If your question does pertain to LEED v4, consider reposting at http://www.leeduser.com/credit/NC-v4/MRc5. But first, review that forum as there might already be a similar question under that credit. Also, as a guest and not a LEEDuser member, you can't see the Bird's Eye View information that explains material streams in more detail and might be additionally helpful.
