June, 1996 - Wastespec Presentation◦ At EPA Region V seminar in Chicago
CWM Spec Attributes CWM Spec Attributes
Provide specs language & tools to implement recycling, reuse, salvage & diversion from landfills
Construction Team: Foster teamwork & partnership
Identify strategies & opportunities
CWM Spec Attributes, contCWM Spec Attributes, cont’’ddTailored to Contract Documents:◦ Includes administrative, procedural & technical
requirements
Includes editor’s notes
Includes references & resources
Documents comparative costs of recycling vs. disposal◦ Recordkeeping is more costly – offset by recycling
savings, lower tipping fees
CWM Spec Attributes, contCWM Spec Attributes, cont’’dd
Identify different types of waste & estimate relative costs of recycling
Prequalify Contractors, Subcontractors, material suppliers for recycling & CWM experience

Develop our own CWM specs◦ Specification text to communicate
requirements◦ Standard forms & worksheets to determine
feasibility & costs
Educate, inform construction personnel to implement CWM practice

landfill names, tipping fee totals, and total disposal cost◦ Communications & Motivational Plans◦ Special Programs: Identify tax credits, rebates,
or other savings
Recycling Evaluation ToolsRecycling Evaluation ToolsTracks costs & quantities of recycled and/or disposed materials
Waste audits show cost-effectiveness of recycling & waste reduction◦ Record feedback on program success or failure◦ Short Audit: Conducted monthly, taking 15 minutes
each time◦ Full Audit: Conducted once during project, at
quarter or third points, taking approx. 1 hour
Pharmacia ResultsPharmacia ResultsBuilding Demolition◦ 35,000 sq. ft., one-story warehouse◦ Recycled: 72% of total demolition debris (included
567 tons of metal)
Diverted from Landfills:◦ 690 tons of solid materials (e.g., concrete, brick)
Net Savings:◦ Approx. $53,000 savings (avoided disposal costs and
recycling revenue)
