We have an existing demolition project in which some of the concrete foundations/concrete slabs/block/brick debris can be taken to a recycling facility which will weigh each load, but some of the same debris cannot be taken to the recycling facility (mostly the brick and some painted block) and must be diverted to either a clean fill facility or a brick re-use company. Both the clean fill location and the brick re-use company do not have weighing capabilities. Could we take the weighed loads that we took to the recycling facility and average the weight of each load and use that calculation to determine approximate weights per load of the loads taken to the clean fill site and brick re-use company? OR do we need to utilize the v2009 MR Credit 2 Table 2 Solid Waste Conversion Factors to determine the weight per load of the hauls that could not be weighed? If we need to use the table, do we use the unit for Mixed Waste or Rubble? My thought is that since all of these loads are essentially the same materials and we have a way to verify what an accurate weight per load is based on the averages we received at the recycling facility, that this unit would be more accurate than those in the table, but I need some advice from those of you more familiar with a similar issue. Thanks!

Jennifer - I have not had experience with your specific situation. We have utilized a truck scale at another facility (like a local feed store) when a scale is not available at the facility our vendor is hauling to in order to get the weight.
The LEED Reference Guide on page 359 (first edition) states that “if exact material weights are not available, use the conversion factors from Table 2 or another defensible conversion metric to estimate the weight of construction waste.” I think that your suggested methodology could be considered justifiable - although I would suggest comparing it to Table 2 (Rubble) to ensure it appears reasonable.

Whoa, are you saying here that an off-site, clean landfill project is considered legitimate waste diversion for MRc2? I know that if the material is used for alternate daily cover, that qualifies, but otherwise, I was not aware that there is a distinction in the Reference Guide between Clean Fill and ordinary fill. This could help with many of our projects. Can you please explain this further?
Thanks!

Susan - Last year I was replying only to Jennifer's question about weight and conversion. I did not dig in further to discuss her diversion locations. Please see http://www.leeduser.com/credit/NC-2009/MRc2?all-comments=true#comment-43338 for additional information.

Thanks for your reply, but I have searched this page in single page display and have not found that specifically addressed. I want to explain that I have always dissallowed it and want to correct myself if I am wrong. SO is a clean fill landfill project a legitimate recycling use for concrete?

IMHO, No. Despite the ADC loophole, I don't think that disposing of material in any landfill is considered diversion from the landfill, which is this credit’s intent. How would that be recycling? I never condoned the 2013 information conveyed above as a legitimate diversion strategy.
Don’t question your previous assessment.
