Construction Waste & Recycling
Construction waste is one of largest waste streams in U.S. It takes up 25%- 45% waste in national landfill.
According to national Association of home builders study (NAHB), 8000lbs of waste are typically thrown into the landfill during the construction of a 2000 square ft house.
8000lb of waste can take up 50 cubic yards of space in landfill. It is about the size of bedroom.
It is about 130 million tons building construction waste per year. 10% from new construction waste, 40% from renovation, and 50% from demolition.

Source separation Vs. Commingled Recycling
Recycle Method Advantages Disadvantages
Source Separation
Higher recycling rates Lower costs; revenues paid for some material Often a cleaner, safer work site
Multiple containers on site Workers must separate materials for recycling More complex logistics Multiple markets; more information to manage
Commingled Recycling
Only one or two containers on site No need for workers to separate materials for recycling Easier logistics One markets; less information to manage
Lower recycling rates Higher recycling costs
Waste management Plan
Estimate type and quantities of C&D waste generated during each phase of the job
Identify how each waste will be managed and market
Provide an estimate of overall job recycling rate
Lay out plans for training, meetings and other communications related to job-site waste management
Provide troubleshooting instruction and contact information
