Construction Waste Sorting & Recycling

Western Disposal offers contractors, builders and homeowners construction waste recycling services to assist in meeting LEED, BuildSmart and city of Boulder recycling requirements. Choose from source-separate containers for each material (you sort the materials at your job site) or a mixed box, where all recyclable material noted below can be combined, and Western will sort it for an additional fee. Please note only de minimis amounts of non-recyclable materials are allowed in mixed boxes.

Our Materials Management Center is home to Boulder County’s only automated construction waste materials sorting center. Funded in part by a grant from the Colorado Department of Public Health and Environment, this service supports customers in attaining their waste diversion goals while protecting the environment, conserving resources and creating jobs.

Waste Report Icon

Construction Waste Diversion Reporting

  • Western Disposal and authorized 3rd party hauler roll-offs will be sorted individually. A diversion report unique to that load will be sent to the email address on file.
  • Self-haul loads will be aggregated on the tipping floor then sorted. An aggregated diversion percentage will be posted below.
  • Western reserves the right to reject, or dispose of as trash, loads containing more than de minimis amounts of non-recyclable material.

Hazardous Materials Icon

Hazardous Materials Strictly Prohibited

The WASTE DEFINED clause in your roll-off contract with Western Disposal prohibits hazardous or toxic wastes as defined by local, state or federal laws or regulations. These wastes include but are not limited to: asbestos-containing material, contaminated soil, wood with lead-based paint, oil-based paints or solvents, florescent lamps, mercury-containing devices.

Self-haul customers will be required to sign an affidavit of non-hazardous materials and provide Western Disposal with a copy of their CDPHE-approved Demolition Notification Application Form prior to tipping.
