If you care about reducing landfill waste, avoiding recycling contamination, and getting more of your plastics actually recycled, this matters. Knowing what plastics does Denver recycle saves you time, reduces curbside rejection, and keeps recyclables out of the trash. Think rinsing yogurt cups, removing metal lids, and never stuffing plastic bags into the blue bin. Take bagged film back to grocery drop offs instead.
In this guide you will get a clear, practical roadmap. First, a quick list of commonly accepted plastics and resin codes. Next, simple prepping rules that cut contamination. Then, a list of items Denver does not accept and where to take them instead. Finally, real world tips for tricky items so you can recycle with confidence.
Quick answer: The short list Denver accepts
If you searched "what plastics does Denver recycle" the short answer is simple, Denver accepts mostly plastic bottles and jugs labeled 1, 2, and 5 at curbside. That means things like PET 1 water and soda bottles, HDPE 2 milk jugs and shampoo or detergent bottles, plus many PP 5 items such as yogurt cups, margarine tubs, and some medicine bottles.
Quick, practical rules, rinse and empty containers, remove pumps and straws, and toss plastic bags in store drop offs instead. Look for the resin code number inside the recycling symbol when you are unsure. For anything not a bottle, jug, or tub, check Denver Recycles online before you toss it, to avoid contamination that can ruin a whole bin.
How Denver recycling works, and who sets the rules
When you ask what plastics does Denver recycle, the first step is to know the players. Denver Public Works sets the rules for city run curbside service, while dozens of private haulers set their own lists for customers they serve. That matters, because curbside programs tend to accept a limited set of rigid containers, bottles and jars, while drop off sites and retail take back programs accept film, bags, foam and odd items.
Why the variation, in plain terms? Processing equipment, market demand, and contamination risk. The city’s contract with processors may only accept certain resin types, private haulers may pay for extra sorting, and stores will take back soft plastics that curbside trucks cannot handle.
Concrete actions: look up the Denver Public Works recycling guide, check your hauler’s website or call, and use local drop off points for plastic bags, wraps and foam.
Plastics Denver accepts, by resin code and examples
If you want a quick, practical answer to what plastics does Denver recycle, here is a clear roster by resin code, with real examples and things to watch for.
#1 PET or PETE, examples: water bottles, soda bottles, salad dressing bottles. Rinse and replace caps if they screw back on.
#2 HDPE, examples: milk jugs, detergent bottles, shampoo bottles, rigid household tubs. These are widely accepted.
#3 PVC, examples: vinyl plumbing pipe, some clear food wrap, shrink wrap. Usually not accepted in curbside recycling, avoid putting these in your bin.
#4 LDPE, examples: squeezable condiment bottles, grocery bags, bread bags. Plastic film is not accepted curbside; take clean bags and film to grocery store drop off.
#5 PP, examples: yogurt tubs, deli containers, ketchup bottles, some takeout containers. Many Denver programs accept PP tubs and rigid containers; lids are sometimes accepted.
#6 PS, examples: foam cups, foam takeout containers, packing peanuts. Foam is not accepted in most curbside programs.
#7 Other, examples: multi layer packaging, compostable PLA cups. Acceptance varies; assume not accepted unless labeled and listed by your local program.
Special cases: remove pumps and metal springs, do not bag recyclables, and never place foam or plastic film in the curbside bin. When unsure consult RecycleDenver or your hauler before tossing.
Plastics Denver does not accept, and why
Denver’s program excludes several common plastics because they break equipment, contaminate loads, or have no viable market. Know these so you do not accidentally ruin a recycling bale.
Plastic bags and plastic film, like grocery bags and sandwich wrap, are a top culprit. They tangle in sorting machines, stop conveyors, and force expensive shutdowns. Solution, take them to retailer bag drop off locations or reuse them for trash liners.
Polystyrene foam, often sold as packing peanuts or clamshell takeout containers, is mostly air. It costs more to collect and ship than it is worth, so recycling centers usually reject it. Look for specialized foam drop off programs or avoid it when possible.
Food soiled plastics and greasy takeout clamshells contaminate otherwise clean loads. A single greasy container can lower the value of a whole bale. Rinse rigid containers before recycling; compost or trash oil‑soaked items instead.
When in doubt about what plastics does Denver recycle, check the City of Denver recycling guidelines or a local recycling app before tossing an item.
How to prepare plastics for Denver recycling
When you think about what plastics does Denver recycle, how you prepare items matters as much as what you toss. Follow these steps.
-
Empty and scrape. Remove food, leftover liquids, and sticky residue. Use a spoon or paper towel for yogurt or peanut butter, then give a quick rinse. You do not need to make containers spotless.
-
Rinse lightly. A quick swirl and shake is enough. For greasy containers, hot water and a small squirt of soap helps. Save water by rinsing several items at once.
-
Caps and lids. Screw caps back on small bottles to keep them from falling through sorting equipment, unless the Denver Recycles page says otherwise. Large lids from tubs can stay on.
-
Labels. Paper labels can stay, they peel off during processing. No need to spend time removing glue.
-
Pumps, sprayers and metal parts. Remove and trash pumps that contain springs or metal. Plastic only pumps can be recycled if Denver accepts that item; otherwise place them in the trash.
-
Flatten bottles. Crush tall bottles to save space, but leave the neck so sorting and emptying still work efficiently.
Special programs and drop off options in Denver
When you ask what plastics does Denver recycle, remember curbside is only part of the picture. For soft film, bread bags, and produce bags, bring clean, dry pieces to grocery store drop off bins at major chains like King Soopers and Safeway. For rigid items that curbside rejects, check Denver Recycles for seasonal drop off events and special collection days where clamshells, tubs, and lids may be accepted. Brand take back programs are growing, so search your product maker for a take back or mail back option. TerraCycle runs free and paid programs for things like coffee pods, beauty packaging, and snack wrappers, and many are available nationwide. Quick tips, rinse plastics, remove food, flatten to save space, and always verify acceptance rules before hauling a load.
Common mistakes that contaminate your recycling and how to avoid them
When you look up what plastics does Denver recycle, the biggest problem is contamination, not confusion. Common errors wreck batches, here are quick fixes you can use today.
Loose plastic bags and film, like grocery sacks or produce bags, clog sorting machines. Solution, stash them in a reusable grocery bag and drop them at store collection bins, not the curb.
Greasy or food filled containers, such as pizza boxes or pasta tubs, spoil other recyclables. Solution, scrape, soak briefly if needed, then air dry. A quick rinse is usually enough.
Mixed materials, like plastic containers with metal lids or paper liners, confuse sorting. Solution, separate parts when possible; if pieces cannot be separated, toss them in the trash.
