Does URCO Composting Apply to Denver Offices and Non-Food Businesses?

URCO's composting requirement centers on multifamily properties with 8 or more units, food waste producers, and hotels. Offices and other non-residential buildings generally carry recycling obligations rather than a composting mandate, though a building with a food service operation inside it changes the analysis.
The answer is usually no on composting and usually yes on recycling. This post explains where the line sits and the situations that move an office building across it.
Do offices have to compost under URCO?
Generally, no. The composting requirement is aimed at the three categories that produce meaningful food waste: multifamily properties with 8 or more units, food waste producers, and hotels.
A conventional office building without a food service operation is not the target of the organics mandate.
What do offices have to do?
Provide recycling access. Non-residential buildings carry recycling obligations under URCO, including container provision and labeling.
That is a real requirement, not a nominal one. Containers, signage, and a licensed hauler still apply on the recycling side.
When does an office building get pulled into the composting requirement?
Three common situations:
1. There is a food service tenant. A ground-floor cafe, a restaurant, or a licensed food operation inside the building is a food waste producer in its own right, with its own composting obligation.
2. There is a full food service operation on site. A staffed corporate cafeteria that prepares and serves food is functionally a food service operation, not a break room.
3. The building is mixed-use. Residential units above and commercial below means both rule tracks can apply on the same premises. See how mixed-use buildings comply.
A coffee maker and a microwave do not create a composting obligation. A kitchen that prepares meals is a different conversation.
Should an office compost anyway?
Often worth doing, for reasons that have nothing to do with the ordinance.
Break room organics, coffee grounds, and lunch scraps are a meaningful share of an office waste stream. Tenants increasingly ask about it during lease negotiations, and building sustainability positioning is a real leasing factor in Denver.
If you go voluntary, run it exactly like a mandatory program. Correct signage, correct accepted materials, correct hauler. A poorly run voluntary compost program produces contaminated loads and rejected material, which helps nobody.
What can go in it if you do?
The same rules apply regardless of whether the program is mandatory. Food scraps and yard trimmings only, with 3-gallon CMA-certified compostable bags as the only permitted liner.
Break rooms are contamination-prone precisely because people assume paper towels and compostable cups qualify. They do not. See what can go in a Denver compost bin.
Frequently asked questions
Does a corporate cafeteria trigger the composting requirement? A staffed operation preparing and serving food functions as a food waste producer. A vending area does not.
What about coworking spaces? Depends on whether food is prepared and served on site. A coffee bar is different from a kitchen.
Do we still need signage for recycling? Yes. Container labeling and accepted-materials signage apply on the recycling side.
Our tenant is a restaurant. Who is responsible? The food waste producer carries its own obligation, and the building may carry obligations of its own. Sort this out in writing between landlord and tenant.
Does URCO apply to warehouses? Non-residential recycling obligations generally apply. Licensed food processing, commissary, and wholesale operations are treated as food waste producers.
Find out what actually applies to your building
Melly's Recycling is a Denver URCO compliance company, not a hauler. The first thing we do is determine exactly what your premises is on the hook for, which for mixed-use and tenant-occupied buildings is rarely obvious. From there we build capacity in gallons, bilingual signage, education, the Waste Diversion Plan, and the records file, and coordinate licensed Denver haulers through a sealed-bid process.
You finish what you started.
