Extracted Content
Source-separated materials are considered 100% diverted for credit calculation purposes. These include:
-
Recovered materials sent to a single-material recycler.
-
Recovered materials sent for off-site salvage/reuse.
-
Materials sent to a qualifying manufacturer or industry take-back program.
-
Salvaged materials are valued at twice the diversion rate (200%) of other diverted materials for credit calculation purposes. Salvaged materials include recovered materials sent off-site for reuse. NOTE: Materials reused on-site contribute to MRc1: Interior Materials Reuse .
-
Mixed C&D materials sent to a processing facility for recovery must take the facility average recycling rate. Recycling rates not verified by a third party must assume a maximum of 35% recovery rate.
-
Materials destined for alternative daily cover or incineration/energy recovery are considered waste (0% diverted).
-
Exclude hazardous waste from calculations. Exclude on-site reuse from credit calculations (include in MRc1: Interior Materials Reuse credit).
-
Exclude excavated soil and land-clearing debris from calculations.
Table 1. Points for C&D diversion
Meet any criteria up to a total of 4 points:
| Pathway | Thresholds | Points |
|---|---|---|
| Path 1 | Divert at least 35% of the total construction and demolition materials. At least 10% of diverted materials must be salvaged or source-separated and sent to a single-material recycler(s). | 1 |
| Path 2 | Divert at least 50% of the total construction and demolition materials. At least 20% of diverted materials must be salvaged or source-separated and sent to a single-material recycler(s). | 2 |
| Path 3 | Divert at least 65% of the total construction and demolition materials. At least 30% of diverted materials must be salvaged or source-separated and sent to a single-material recycler(s) | 3 |
| Path 4 | Salvage or source-separate and recycle these targeted materials: clean gypsum, carpet, ceilings, and furniture. Targeted materials diversion must exceed 10% of the total construction and demolition materials. | 1 |
REQUIREMENTS EXPLAINED
This credit encourages projects to plan and make design changes that reduce waste during construction. It rewards behavior change that leads to increased quality of recycling and a higher potential for materials to be recovered during construction.
