Example CWMP
• There is no standard or required format• LEED projects should include a ‘target recovery rate’

Making a difference by recycling
• By Recycling an Average Roof of 240 Squares, you can divert:– Approx 4000 cubic feet of
insulation– About 6000 pounds of
membrane
• This amount of material would fill three average swimming pools

Landfill
Average Roof of 30-35 squares
3.5 tons or 7000 lbs of roofing
5 cubic yards of landfill space
The equivalent of more than one year of a typical family’s trash
Instead, used at 5%, this could help pave over 50 feet of typical road!

WILL IT SLOW DOWN THE JOB?
Not because of labor You can make recycling easier than disposal
Not because of service Hauling recyclables is the same as hauling waste
Not because of logistics Recycling can be coordinated specifically to the job
site, to fit in the project schedule

KEYS TO SUCCESS OF YOUR RECYCLING EFFORT
100% Support from Crew + SubsGet the paperwork right
Adequate space on siteGood recycling partners

Source Separating Saves
16
Waste” is an asset. Treat it like one.Separation captures the full economic value of the asset.Mixing together creates a waste.
Mixed debris recycling rates are < or << than rates achievable with separation.
Mixed debris costs are = or > than disposal costs.

What to look for in a Recycling Partner
• Service– Distance from jobsite– On-call pickups?– References
• Pricing– $/load, payment terms– Size of load, extra charges

What to look for in a Recycling partner (cont’d):
• Safety– Citations? Accidents?– Insurance Certificate
• Documentation

Things to Watch Out For
• Code Issues• Hazardous Materials
– Lead– Asbestos– Usually start with an engineering survey to help avoid – Note: Hazmat not counted in LEED
• Lack of End markets for salvaged materials• Design for reuse/deconstruction
– Make it easy for the next user
• Problem Recyclers

Quick Notes on Problem Recyclers
• 100% diversion rate is claimed• Lack of documentation, signed by ‘Bob’• Hesitant to give you a tour• Won’t give you a straight answer if you ask
where material is going.– ‘Chain of Custody’ for disposed material – where it ultimately ends up is
also important– If you ever got audited by USGBC you could get those points taken away

CWMP ON THE JOB
• Recycling containers must be at least as convenient to use as trash bins.
• If your jobsite is large, make certain that bins are centrally located and easily accessible.
• Effort should be made to see that containers do not become over full.
• To prevent unwanted drive-by dumping, locate recycling containers away from public sight and access.
• Make the signs on the bins removable – so they can be taken off and exchanged when the bins are emptied.
• And put the General Debris bin the farthest away from the work area – make it easier to recycle materials than it is to throw them away – a classic real-world tip.
• Place trash and recycling bins for the crew at the site entrance.

SUMMARY
• You can reduce costs by recycling• You can market your recycling activities• Roofing recycling can positively impact the
environment• Source separating saves• Retain your documentation• General Contractors prefer to work with Subs that
know CWMP
