Requires state agencies and contractors to recycle 50% of the waste generated on public works construction and demolition sites

S 6293 requires New York state agencies and contractors working on public construction or demolition projects to recycle or reuse at least 50% of the construction and demolition debris generated on-site, measured by weight. This applies to projects starting one year or more after the law takes effect (January 1, 2026), with a lower 25% requirement for projects starting within the first year. Contractors must submit documented proof of compliance, including notarized affidavits from the agency, contractor, and waste hauler, to the state comptroller within 30 days of project completion. The law excludes hazardous materials like lead or asbestos-contaminated debris from the recycling mandate.
