Larimer County Recycling Guide

Breaking It Down: How Larimer County Actually Handles Your Recycling

Most people in Larimer County don't realize their recycling doesn't go to a local facility. It gets hauled somewhere around 80 miles south, usually to a materials recovery facility outside Denver, and a lot of it comes back out if it's contaminated. That's why the Larimer County Recycling Guide isn't just suggestions — it's basically a set of rules to keep your stuff from getting trashed at the MRF. I've been dealing with this system for years, and the thing that trips people up most isn't the obvious stuff like food containers. It's the smaller items. Number 5 plastics, thin film, and anything that doesn't fit through the screening holes at the sorting facility gets rejected. I learned this the hard way when I spent three years putting coffee cups and small plastic clamshells in my blue cart, only to find out they were contaminating entire batches. Now I just toss those in the trash and recycle what I actually know sorts correctly.

What Goes in the Bin (and What the Larimer County Recycling Guide Says)

Cardboard and paper are your safe bets. Flattened boxes go in. Junk mail goes in. Paper towels and napkins go in the trash — they're contaminated with food and oils and the sorting equipment can't separate them efficiently. Glass is accepted in the county, which surprises a lot of people because not every municipality takes glass in curbside programs. But here's the catch: put glass in a sealed container before tossing it in the bin. Loose glass breaks and shreds the paper and cardboard around it, making both unrecyclable. I started putting my glass in a old cereal box, sealing it with tape, and then tossing the whole box into my cart. It's an extra step, but it keeps the whole load clean. Plastics number 1 and 2 — that's water bottles, milk jugs, detergent bottles — go in. Plastic number 5 sometimes goes in depending on the current market conditions, and honestly the county updates this periodically. The best approach is to check the website before you make assumptions, because plastic recyclability changes when markets shift. Plastics number 3, 4, 6, and 7 generally do not go in the bin. Metal cans, aluminum, and steel go in without issues. Paperboard like cereal boxes need to be empty and dry. Nothing else needs to be rinsed out beyond a quick shake — food residue is the real contaminant, not a little leftover sauce.

Common Mistakes That Ruin Batches

Plastic bags are the biggest problem. They wrap around the sorting equipment and shut down entire lines. You cannot put them in the recycling bin. Take them back to the store drop-off points instead — most grocery stores near me take them at the front entrance. This isn't a suggestion from the guide, it's a hard rule and it exists for a reason I've seen on the news multiple times when facilities had to halt operations. Things labeled "recyclable" or "made from recycled materials" don't automatically belong in your bin. That's marketing language, not a sorting instruction. If the item isn't a standard number 1 or 2 plastic bottle or jug, check first. I found out too late that my compostable cups, despite being labeled eco-friendly, actually contaminate the recycling stream because they don't break down the same way and require different processing. They go in the trash unless you have access to commercial composting, which most Larimer County residents don't. Hazardous materials absolutely do not go in the recycling bin. Paint, chemicals, batteries, electronics — these are all taken to special drop-off events or facilities. The county holds hazardous waste collection events a few times a year, usually in spring and fall. Mark your calendar for those.

The One Thing the Guide Doesn't Tell You

Here's something nobody seems to mention: the county's recycling program changed its accepted materials list after 2022 when contract renewals shifted which MRF they use. Some items that were accepted before are no longer accepted, and vice versa. I went through this when the new rules came out and I had to learn the hard way that my old mental list was obsolete. The workaround was calling the county's sanitation department directly and asking them to read me the current accepted materials list over the phone. No website update had caught up at that point, and the staff member was able to clarify exactly what was still acceptable. If you're ever unsure, a phone call to Larimer County Public Works at (970) 498-4400 is faster than guessing and risking contamination fines or rejected loads. The bottom line is that the Larimer County Recycling Guide works when you follow it precisely, and it breaks down when you assume things based on guesswork or wishful thinking. The county provides their official materials on their website, and I'd recommend downloading or printing the most recent version rather than relying on memory. The rules shift based on market demand and facility capabilities, and the only reliable source is the current publication from the county itself. If you want the direct link, it's under the Sanitation and Recycling section of larimer.gov, and it gets updated whenever the MRF contracts change — which happens more often than people expect. I know this is tedious, and I'm not going to pretend it's easy. But the alternative is having your entire bin rejected by the hauling company, or worse, having your recyclables end up in a landfill because they contaminated a batch. The effort of checking once before you toss something in is about 30 seconds and it saves a lot of frustration later.
