Inquiry

Methodology #1 Each co-mingled load of construction debris is weighted at the MRF and visually inspected then the percentage of each recyclable material is tallied. The recyclable materials are then processed for sale on the secondary market. The tallied data is documented in a running monthly report created by either the MRF or the Hauler and is submitted to the contractor for the project. Methodology #2 The MRF\'s self-reported recycling percentage rate (for the entire facility) is applied toward specific LEED projects\' delivered co-mingled tonnage brought to that facility. We are aware of the CIR ruling dated 12.2.05 stating that a project can use this methodology if a facility has government oversight over a facility\'s recycling rate calculations. In our case we have government oversight of the MRFs overall recovery rates but the reporting methodology required by the oversight agency doesn\'t account for C&D debris - asphalt, gypsum wallboard, and concrete tonnage which is processed through those facilities. LEED NC v2.2 accepts and credits concrete towards MRc2 but this disconnect between how the oversight agency tracks materials versus what is actually processed in a facility doesn\'t allow for accurate reporting and subsequent award of LEED credit in our local market. Please let us know if one or both methods are acceptable for tracking and documenting co-mingled boxes for MRc2.
