Slide 1
Why Use A Construction Waste
Management Plan?
• Increase profits
• Increasingly Specified or Required
• Reduce disposal costs
• Cleaner jobsite
• Improve relationship with General Contractor

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

Setting up A CWMP
Set a Diversion Goal
Identify Recyclable Products
Estimate Quantities and Seek Bids
Select Recyclers
Train Crew
Monitor the Program
Calculate Final Diversion Rate and Savings

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

MAKING A DIFFERENCE BY RECYCLING
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!

Transportation Cost Per Ton
Compared to disposal (bottom bar), recycling costs less for
nearly all construction and demolition materials.

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
14
KEYS TO SUCCESS OF YOUR
RECYCLING EFFORT
Adequate space on
site
Good recycling
partners

100% Support from
Crew + Subs
Get the paperwork
right
Source Separating Saves
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.
16
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
17
What to look for in a Recycling partner
(cont’d):
• Safety
– Citations? Accidents?
– Insurance Certificate
• Documentation
18
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

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
21
• 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
Summary: Benefits of Construction
Waste Management
• Trim Costs
• Create Environmental
Benefits
• Win More Bids
• Assist Charitable
Organizations
• Meet Codes

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
