FAQs about MRc7 :

The project building has a waste/recycling hauler that picks up containers for the building several times a week. However, at the time of pick up the building management does not know how full the containers are. The waste hauler is not willing to track t

Is it acceptable to use a volume metric for one waste stream (landfill waste) and a weight metric for another (recycling)?

How does the a project building track a diversion rate for recycled batteries when tracking recycling batteries is easy, but tracking batteries thrown in the trash is extremely difficult?

The recycling waste generated from the project building is comingled. To achieve MRc7, does the recycling waste need to be tracked by the categories of waste identified in MRc6 (glass, metal, paper, cardboard, etc.)?

We compost all of the landscape waste generated onsite. Can we include landscape waste in the credit calculations?

Are mercury-containing lamps included in the credit calculations?

EBOM-2009 MRc7:Solid Waste Management—Ongoing Consumables

Tracking compacted trash and loose recyclables

My project is having problems tracking their trash and recyclables by volume. The trash is compacted 4:1 in a trash compactor. This trash remains in its compacted state even when it is in the landfill. The recyclables are collected loose and not compacted. I assumed we would be tracking the loose recyclable volume vs a calculated loose trash volume, in order to compare apples to apples. But could we consider the reduction in total volume in the landfill by the compacted trash as fulfilling the credit intent and count the compacted volume against the loose recyclable volume?

I don't think that will fly Kristen. LEED allows projects the option of volume or weight because neither metric is really perfect, and because tracking by weight (which seems on balance the better measure) is very difficult for many projects which do not have appropriate scales available. But as you said - the apples to apples comparison doesn't work if you are compacting one of your streams and not the others. LEED is less worried about the actual displacement of air/space resulting from your waste than in the relative amounts of waste vs recycling. So your original assumption was accurate - you should compare your loose recyclable volume vs a calculated loose trash volume. And make sure you clearly document your method for that calculation! Hope that helps, Dan
