Westminster, CO Trash & Recycling: Recycling Requirements (2026)

requires that "all collectors providing solid waste collection services to residential customers shall offer and provide curbside recycling collection services to all such customers who desire such services" for materials the City Manager designates under Section 5-7-9. Collection of recyclable materials must also be offered to every multifamily and commercial customer, though collectors handling only large bins for short-term projects like construction roll-off dumpsters are not required to offer recycling for that activity. Frequency is fixed: residential curbside recycling must run at least once monthly and on the same day the collector picks up solid waste from that customer, while multifamily and commercial recycling frequency must be enough to prevent the bins from overflowing.

Once a customer sets out recyclables, the collector cannot dispose of properly prepared material by any means that results in it not being recycled, and ownership of the material passes to the collector only once it is actually collected. The City Manager sets the list of designated recyclables after consulting licensed collectors and the environmental advisory board, weighing factors like market price, availability of markets, and transportation safety risk, and that list is kept on file for public inspection at the City Clerk's office. Collectors must also submit an annual recycling report to the City by March 31 describing volumes and services from the prior year, which the environmental advisory board reviews for compliance.
