Western Disposal offers contractors, builders, and homeowners construction waste recycling services to assist in meeting LEED, BuildSmart, and city of Boulder construction waste recycling requirements. Choose from source-separated 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.
Our Materials Management Center is home to Boulder County’s only semi-automated construction waste recycling sorting center. Funded in part by a FRWD grant awarded by the Colorado Department of Public Health and Environment, this service supports customers in attaining their construction waste recycling goals while protecting the environment, conserving resources, and creating jobs.
