What a Fort Collins trash cart may not take, and where it goes instead

Field notes · Checked against Colorado Department of Public Health and Environment, City of Fort Collins and Larimer County pages on October 4, 2026 · About an 8-minute read

Three rulebooks, stacked

Most arguments about a cleanout come from reading only one of them. The state bans certain materials from any solid waste site. The City separately requires some materials to be recycled inside city limits, whether or not the state cares. And the facility at the end of the trip keeps its own list, which is why a refrigerator is turned away at a recycling yard that happily takes a stove.

The state list, as the health department writes it

The Colorado Department of Public Health and Environment publishes a short list of residential materials prohibited from disposal in a solid waste site or facility: lead-acid batteries, liquid wastes or wastes containing free liquids unless the facility is specifically approved to accept them, used oil, waste tires unless an individual has done due diligence and established there is no other option, and waste electronic devices and computers.

Two of those come up in almost every garage. Larimer County’s electronics recycling page says that per state statute electronic devices must be recycled and cannot be discarded in Colorado landfills, and the City’s A to Z entry for electronics puts it in one line: in Colorado it is illegal to dispose of electronics in the trash. The tire entry says the same about tires anywhere in the state. Our TV and electronics guide lists what each screen costs to recycle at Timberline.

What the City requires on top

The City’s code compliance page lists the materials that must be recycled in Fort Collins: electronic equipment, cardboard, household hazardous waste, and construction and demolition debris including aggregates and concrete, metal, untreated wood and cardboard. The cardboard rule has its own history. Per a 2013 City ordinance it is illegal to throw cardboard in the trash here, as the A to Z entry explains, with an exception for cardboard that cannot be recycled, such as waxed produce boxes or a greasy pizza box.

Preparation is part of the rule. Boxes are flattened, large pieces are cut down to fit loosely in the curbside bin, and anything taken to a drop-off is cut to about four feet square. After a move that is a few minutes of work, and it keeps the recycling cart from being passed over.

Paint, the thing most cleanouts get wrong

Liquid paint is both a banned liquid and a required recyclable, and the City’s guidance is blunt: liquid paint should never be put in the trash, poured down a drain or dumped on the ground. The latex paint entry explains the test for which kind you have, since paint that cleans up with water is latex and paint that needs thinner or mineral spirits is oil-based.

Latex and other water-based paints are taken free of charge through PaintCare at the listed drop-offs, which include the Timberline yard and two Ace Hardware stores in town, each with its own restrictions. The oil-based entry sends enamels, varnishes, shellacs, lacquers, stains, epoxy bases, sealers and anything containing cadmium or lead to household hazardous waste instead. Cans still in reusable condition can go to the county’s Drop ’N’ Swap, where they are offered back to residents for nothing, and quantities above 50 gallons need a call to the commercial recycler the City names.

Larimer County’s household hazardous waste facility takes paint, chemical and liquid wastes, flammables, household cleaners, aerosols, fluorescent bulbs and batteries free from county residents, and it is closed to the public on Wednesdays. That single trip clears most of a shelf.

Batteries, by type

Only one kind is simple. Because alkaline batteries have not been made with heavy metals since the late 1990s, the City says they may be thrown away, though recycling is preferable; its alkaline entry adds that every other type is made with heavy metals and must be recycled, and that treating any battery as hazardous waste is the safest route. Residential batteries are free to recycle at the Timberline yard.

Lithium-ion cells are the dangerous exception, and the City’s entry does not hedge: they should never be put in curbside recycling or the trash, they are highly flammable when mishandled, and they have caused multiple fires at recycling facilities in recent years. Tape the ends with clear tape before dropping them off. Anything with a rechargeable pack counts, which in a garage means the cordless drill, the hoverboard, the e-bike battery and the old laptop.

Pressurised, oily and mercury-filled

Propane is a container problem rather than a chemical one. The City’s propane entry says canisters must not go in the trash or curbside recycling because any pressurized container can be hazardous, and the county facility accepts canisters and tanks under 20 pounds while advising on bigger ones.

Used motor oil has its own etiquette. The City entry asks for oil free of gasoline, antifreeze, solvents, dirt and water, in a clean container with a tight cap such as a milk jug, and notes the plastic bottles it came in belong in the trash rather than the recycling. Fluorescent tubes and compact bulbs contain mercury, so the bulb entry keeps them out of curbside recycling and sends them to a drop-off, where fees may apply.

Anything with refrigerant

A fridge is not simply a heavy appliance. The City’s appliance guidance says state law requires an appropriately licensed company to remove the refrigerant before disposal, and the Timberline yard accepts no Freon items at all. The federal rule puts the duty on whoever disposes of the unit last and expects a signed statement naming whoever recovered the refrigerant. At the county gate the charge is $36 with Freon and $20 without, per the 2026 fee schedule; the appliance removal guide goes through the questions to ask.

Addresses that have not caught up

Several City entries still send readers to 5887 S. Taft Hill Road, the old landfill site. For hazardous waste and electronics recycling that is still correct: the county kept both there when public disposal moved to the Central Diversion & Transfer Station on West Trilby Road in August 2026, as the county’s page sets out. For anything else at that address, call first. The guide to where Fort Collins junk goes now follows the whole change item by item.

What happens if the pile just stays

Code compliance is the other half of the rule. The same City page treats accumulated junk or debris as a public nuisance, along with overgrown vegetation and dangerous structures, and when a violation outlasts its deadline the City may hire a contractor to clear it and bill the property owner for the work plus administrative fees. Trash carts also live out of sight on non-collection days and may go out no more than 12 hours before pickup.

The sort that makes a cleanout cheap

1. Chemicals and cylinders. Paint, solvents, aerosols, cleaners, propane and every battery except alkaline go in one box for the county facility, closed on Wednesdays.
2. Electronics. Screens, computers and anything with a circuit board go in a second pile for a recycler, not into the load.
3. Required recyclables. Cardboard flattened, metal and untreated wood set aside, since the City counts all three as recycling rather than trash.
4. Everything else. What is left is ordinary junk a hauler prices by volume, and it is a smaller load than it looked an hour ago.

The garage cleanout guide runs the same sort shelf by shelf, and a contractor taking the job should be able to say which recycler and which gate each pile is going to.
