Same as credit MR 2.2, except for percentage diverted (75% in Materials and Resources 2.2)

Divert 50%

Intention:

1. Divert construction and demolition debris from landfills and incinerators
2. Redirect recyclables back to manufacturing process
3. Redirect reusable materials to appropriate sites

Implementation:

• Develop a construction waste management plan to at a minimum, identify materials to be diverted:
  • salvage, refurbish, recycle, reuse
  • Include:
    • doors and windows
    • salvaged flooring, paneling, cabinetry, beams
    • recycled cardboard, metal, brick, acoustical tile, concrete, plastics, clean wood, glass, gypsum board, carpet and insulation.
    • MEP (mechanical, electrical, plumbing) updated
  • Exclude:
    • soil, rocks, vegetation
    • hazardous material
• Designate site in construction area for separation process
• Track recycling through construction process (general contractor to keep records i.e. receipts, of recyclable and waste diversion pickups)
• Diversion can include donation to charitable organizations as well.
• Calculation:
  • Based on WEIGHT (lbs.) or VOLUME (cubic ft.)

Codes/Standards Applied:

1. none

Extra Credit:

• divert 95% (instead of 50% or 75% as in MR2.2)

Submittal Phase:

• Construction (tip: all Materials and Resources credits are submitted in the construction phase except MRP1)
