Selective Hauling understands the importance of earning every possible point when our clients are seeking LEED certification. We can help you achieve your goals by helping you understand what you need to accomplish from a LEED construction waste management standpoint.
According to the LEED guidelines, a project can earn either one or two points from construction and demolition waste management. Calculations can be made by weight or volume.
Under the one-point option, the project needs to divert at least 50% of the total construction and demolition material, and the diversion must include at least three material streams. Under the two-point option, the diversion rate is 75%, with four material streams. It is important to note that those streams must be hauled from the project directly to each of their final destinations in order for it to be count as one material stream, and therefore commingled materials count as only one stream.
“Commingled materials that are processed in the same way (i.e. over the same recycling line) are counted as one “stream” in LEED, even if the processing facility separates the output into multiple materials for recovery after processing.” – Guide to LEED Certification: Commercial
The LEED Guide also offers methods to add more material streams:
“Since commingled recycling counts as one stream, projects are encouraged to seek additional material streams through waste prevention and diversion. Successful projects have implemented the following strategies to count as material streams in LEED:
- Quantify waste prevention design and construction techniques that result in source reduction.
- Stage collection bins onsite to correspond with construction phases and contractor schedules. If one trade is onsite for a defined period that has a recyclable waste stream, consider having a single bin for that type of waste instead of—or in addition to—a commingled bin (examples include a bin for concrete recycling during demolition, or separate bins for drywall, wood framing, or roofing waste during those phases).
- Salvage components from the project renovation and reuse them in the project or for other projects.
- Donate surplus materials.
- Participate in manufacturer take-back programs for products like ceiling tiles or flooring.
- Work with subcontractors and/or finish material suppliers to eliminate or recycle packaging waste and take-back extra materials.” – LEED Guide to Certification: Commercial
