Construction / Demolition

Construction & Demolition

Construction and demolition activity accounts for nearly 30% of the waste generated in California! The California Green Building Code, or CALGreen, requires all permitted residential and non-residential construction, demolition and addition/alteration projects to recycle or salvage at least 65% of nonhazardous project construction materials.

ReGen recycling and reuse programs help contractors, builders and residents meet CALGreen requirements – and work toward LEED Building standards – without breaking the budget.

Contractors are responsible for maintaining weight receipts for the duration of the project. Separated materials are indicated on the weight receipts. Loads are subject to inspection. To maximize your cost savings and diversion rate, separate your loads by material type and do not mix materials together.

Save Money With Source Separated Loads

To cut costs and boost recycling rates, try source-separating materials at your job site. ReGen Monterey offers discounts for clean loads separated into categories like wood, concrete, asphalt or soil. When you can’t maintain separate dumpsters, our Materials Recovery Facility can sort your recyclables from mixed construction waste at the basic solid waste rate.

CALGreen Diversion Requirements

ReGen Monterey makes monthly calculations of the construction and demolition materials diverted at the Materials Recovery Facility – including the tonnage of material entering the facility, the tonnage diverted from the landfill, and the tonnage disposed in the landfill. Diversion is not tracked on a load-by-load basis.

Please keep Your Scale Receipt as Proof of Diversion. When arriving at our scales, be sure to communicate your needs with ReGen staff. This will ensure all proper information is included on your receipts. Labels on your scale receipt outline the materials brought across ReGen scales and where those materials are directed.

  • Receipts labeled as “15-C&D-MRF” certifiy at least 65% diversion for tonnage delivered on that receipt.
  • Receipts labeled with the following codes mean 100% diversion of that load.
    • 17-KD-Green
    • 372-Clean Sheetrock
    • 91-Aggregates-Clean Asphalt
    • 94-Aggregates-Clean Concrete
    • 101-Clean Oversize/Rebar
    • 95-Clean Soil
  • Receipts labeled as “13-Bulky/Public Accepted at MRF” or “10-MSW” indicate 0% diversion.

You can view ReGen’s CALGreen Diversion figure in our monthly Board agenda under Finance, Operating and Recycling Reports. The “12-month rolling average diversion, C&D diversion” figure is the diversion percentage you can use for your project reporting.

For residential and commercial recycling, including collection bins, please contact the curbside service provider in your area.
