What Is URCO (Waste No More) in Denver?

The Universal Recycling and Composting Ordinance and Initiated Ordinance 306, explained in plain language.
URCO is Denver's Universal Recycling and Composting Ordinance. It requires apartment buildings with 8 or more units, food service businesses, and hotels to provide recycling and composting service alongside trash. It came from the voter-approved Waste No More initiative, and enforcement begins September 1, 2026.
If you have heard both names and wondered whether they are two different rules, they are not. This post explains where the ordinance came from, who it covers, what it requires, and what happens if you skip it.
Where did URCO come from?
In November 2022, Denver voters passed Initiated Ordinance 306, better known as Waste No More, with roughly 70 percent approval. It was not close.
The ballot measure established the principle: if a building or business generates waste in Denver, it should give the people inside it a way to recycle and compost, not just throw everything in one dumpster.
Denver City Council then passed Council Bill 25-0628 to implement the measure, which set the compliance framework and the September 1, 2026 enforcement date. The city's overview lives at denvergov.org.
Why is it called both URCO and Waste No More?
Same rule, two names.
Waste No More is the campaign and ballot-initiative name. URCO, the Universal Recycling and Composting Ordinance, is the operational name the city uses in its rules and enforcement documents.
If you hear either one, you are hearing about the same obligation.
Who does URCO cover?
Three categories carry the composting requirement:
Multifamily residential properties with 8 or more units. Apartments, condos, student housing, senior living, manufactured home communities.
Food waste producers. Restaurants, cafes, bars, breweries, grocery stores, caterers, ghost kitchens, commissaries, food halls.
Hotels. Including their kitchens, banquet operations, and in-house restaurants.
Non-residential buildings generally carry recycling obligations. The composting requirement centers on the three categories above, because that is where the food waste is.
What does URCO actually require you to do?
Four things, and they are more operational than people expect:
Provide the service. Composting collection has to exist on site and be reachable by the people who generate the waste.
Use a licensed hauler. Your hauler has to be licensed by the City and County of Denver. An unlicensed hauler does not satisfy the ordinance regardless of price.
Label and educate. Container identification plus accepted and prohibited materials signage, in English and Spanish at minimum.
Document it. A Waste Diversion Plan and ongoing records that show the program is real.
The last one is where most properties are weakest, and it is the one an inspector can check in ninety seconds.
Why does URCO exist?
Denver diverts less than 30 percent of its solid waste and has set a target of 70 percent by 2032. Organics are the biggest single lever available.
Statewide, Colorado buries about two million tons of food scraps and yard trimmings in landfills every year, and organic materials make up roughly 37 percent of the waste stream, according to the 2025 Eco-Cycle and CoPIRG Foundation report on recycling and composting in Colorado.
You cannot move a diversion number that large without touching food waste. URCO is how Denver decided to touch it.
What happens if you ignore it?
Denver Municipal Code §48-47 sets an escalating fine structure: $150 for a first citation, $500 for a second, and $999 for a third and each one after that.
The multiplier is §1-13, which treats each continuing day as a separate offense. A problem left unfixed does not stay at $150.

Frequently asked questions
Is URCO the same as Denver's residential compost program? No. Denver Solid Waste Management's residential composting serves single-family and small residential customers on city collection. URCO applies to covered buildings and businesses on private hauling service.
Does URCO apply to my office building? Offices generally carry recycling obligations. The composting requirement centers on multifamily properties with 8 or more units, food waste producers, and hotels.
When does enforcement start? September 1, 2026.
