Proposal: Require general contractors who pull permits to prepare a Waste Management Plan for all projects valued at more than $50,000.
Goal: The Waste Management Plan shall identify means and methods to effectively manage demolition and construction waste material by reuse, salvage, or recycle to the extent economically
feasible. Waste disposal in landfills or incinerators shall be minimized, thereby reducing transport costs, transport emissions, transport traffic, landfill volume, and disposal costs.
Ideally, 95 percent by weight of construction and demolition waste shall be salvaged/recycled.
Specifically, the construction team shall salvage and recycle as much non- hazardous demolition and construction waste as possible, including the following materials:
Demolition Waste:
Asphaltic concrete paving
Concrete
Concrete reinforcing steel
Brick
Concrete masonry units
Wood studs
Wood joists
Plywood and oriented strand board
Wood paneling
Wood trim
Structural and miscellaneous steel
Rough hardware
Roofing
Insulation
Doors and frames
Door hardware
Windows
Glazing
Metal studs
Gypsum board
Acoustical tile and panels
Carpet
Carpet pad
Demountable partitions
Equipment
Cabinets
Plumbing fixtures
Piping
Supports and hangers
Valves
Sprinklers
Mechanical equipment
Refrigerants
Electrical conduit
Copper wiring
Lighting fixtures
Lamps
Ballasts
Electrical devices
Switchgear and panelboards
Transformers
Construction Waste:
Masonry and CMU
All untreated wood, including lumber and finish materials
Wood sheet materials
Wood trim
Metals
Roofing
Insulation
Carpet and pad
Gypsum board
Unused (leftover) paint
Piping
Electrical conduit
Packaging: Regardless of salvage/recycle goal indicated above, salvage or recycle 100 percent of the following uncontaminated packaging materials:
Paper
Cardboard
Boxes
Plastic sheet and film
Polystyrene packaging
Wood crates
Plastic pails
Beverage and packaged food containers
Recycle & reuse locations: The Waste Management Plan should identify possible recipients of the diverted materials.
Local reuse centers: The City of McCall could support a central location to filter recycled construction materials that could be reused (Construction Thrift Store).
Local recycle/reuse vendors: The City of McCall can prequalify local entities to receive and reap benefits from co- recycling materials.
Wood: use a centrally located industrial hopper grinder to chip waste framing, sheathing, wood crates, and pallets.
Drywall: gypsum board can ground into dirty gypsum powder and used as a soil stabilization additive.
Glass: glass can be crushed and reused as a fine aggregate stream at the concrete batch plant
Cardboard: collaborate with local businesses who already flatten, bind and transport recycled cardboard to Boise recycling facilities.
Plastic: identify businesses with potential waste heat (asphalt plant) that could be used to produce steam that softens plastic to make plastic cubes for easier transport to recycle/reuse
centers.
Steel: collaborate with local steel fabrication businesses to co-recycle waste rebar, steel pipe, and other steel scraps.
Concrete, rock, masonry block: Waste concrete can be crushed and reused as aggregate
Cleared slash and similar organic material: transport to the local sewer plant where wood chips can be mixed with sewer sludge for non-garden landscaping applications.
Incentives: The City of McCall could incentivize contractors to divert for reuse or recycle construction materials by offering building permit discounts via rebates issued upon receipt
of verifiable waste diversion documentation.
Waste Reduction Calculations and documentation:
Before request for Substantial Completion, submit calculated end-of-project rates for salvage, recycling, and disposal as a percentage of total waste generated by the Work. Complete
a table similar to the example below.
Recycled/Salvaged/Diverted Materials
Hauler or Location
Quantity of Material (tons)
Total Construction Waste Diverted
Landfilled Materials
Total Construction Waste Landfilled
Total Construction Waste
Total Construction Waste Diverted + Total Construction Waste Landfilled
Percentage of Construction Waste Diverted from Landfill
(Total Construction Waste Diverted / Total Construction Waste) * 100
