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

An unusual situation with Recycling Tickets

As the general contractor on a recently completed LEED project, all of the tickets I've received from the off-site waste separation facility listed the tonnage diverted by item, i.e., concrete, metal, wood, plastic, cardboard, etc. Then, one of our subcontractors - who provided his own containers -used the same recycling facility, the tickets I've received from them do not separate the items, the tonnage recycled was just provided, not the breakdown. The recycling facility assured me the material was 100% recycled and not landfilled - can I include that tonnage as "MIXED DRY REC." since i cannot be more specific as to the contents? Thanks!

Christine - Was this waste collected as commingled or site-separated? Based on your description of what you received from the recycling facility, it seems like your description makes sense and you'd need to also show this as commingled on the form (Diverted or Landfill Waste column) and provide backup from the recycling facility showing the overall recycled percentage.

Michelle - the waste was commingled and separated off site. Just so I understand, your interpretation is I can use the tonnage as Mixed Dry Recycled, as long as i have backup from the recycling facility showing the overall recycled percentage?

I am glad to know it was commingled. This makes this approach even more straightforward. To answer your question - yes; however, I want to clarify that the percentage from the recycling facility is for your specific job and not a facility-wide recycling rate. If it is not specific, see the last FAQ above and the reference to LI ID #10060 - http://www.usgbc.org/leed-interpretations?keys=10060 regarding facility-wide recycling rates.
