The city of Denver put sustainability talk into action and made reducing waste a legal requirement.
The City and County of Denver’s Universal Recycling and Composting Ordinance went into effect in September 2026 as the result of a voter-approved ballot initiative called “Waste No More” that nearly three in four Denver residents backed. The ordinance expands recycling and composting access across the city and is designed to keep valuable materials out of landfills and in circulation.
How Recycling and Composting Are Being Implemented
The ordinance requires buildings like residential buildings, non-residential buildings and food businesses to provide recycling and composting resources. This means that people have access to contributing to diverting waste that previously would have gone into a landfill.
The ordinance also covers permitted events and construction and demolition projects. For construction and permitted events, no permit will be issued without a submitted Waste Management Plan.
The city is taking an education-first approach and is focused on providing guidance and support to help Denver adapt.
“Now that the Universal Recycling and Composting Ordinance is in effect, our focus is on providing clear guidance, practical tools, and real support so every covered entity can confidently reach compliance,” said Elizabeth Babcock, Executive Director of Denver’s Office of Climate Action, Sustainability and Resiliency.
Over the past year, the city has engaged thousands of building owners, restaurants, event organizers and contractors as the policy was refined. The first week of September, the office held a resource fair at McGregor Square attended by more than 100 businesses, property managers and haulers preparing to meet the new requirements.
Communities Care About Recycling
Denver is not the first city to mandate composting and recycling — San Francisco has had a similar ordinance since 2009. Considering that approximately 70-71% of voters were united in the initiative, it shows a wider trend of environmental awareness, a dwindling tolerance for waste, and a united community against crowding landfills.
Communities across the country are moving toward waste diversion not as an optional program but as a civic expectation. The new legislation in Denver is demonstrating a shift in how Americans think about what happens to their trash.
For Green Living readers already composting at home or supporting organizations like Waste Not Arizona — which diverted over 2.9 million pounds of food from Arizona landfills in 2025 — Denver’s ordinance is a glimpse of what policy can look like when communities join together and environmental values become the norm.
