The hauler left a tag on the recycling cart. Or a custodian held up a clear bag of coffee cups, pods, and half-eaten lunch pulled from the paper bin. You've sent the reminder email and run the training twice, and the bins look the same a month later.

Much of the recycling contamination at work gets decided at the bin, in the moment someone stands over it with a cup in hand. The opening shape, the label, and where the station sits are things you can specify, and they stay in place after the training is forgotten.

America Recycles Day falls on November 15, and many facilities use it as a reason to look at their programs again. A good place to start is the station itself: which recycling receptacles stand in each room, and how their openings and labels steer the person in front of them.

What Recycling Contamination Means at Work

Recycling contamination is anything in a recycling container that your hauler or the materials recovery facility (MRF) can't accept. That includes items that aren't recyclable in your program and recyclable items that arrive dirty, wet, or full. Acceptance of items like pizza boxes and coffee cups varies by program, and liquid left in any container causes problems at the sort. Your commercial hauler's accepted-materials list is the reference for what your stations should take.

At work it shows up in two forms. Trash in the recycling bin is the familiar one. The other is a recyclable in the wrong recycling bin, like office paper dropped in with bottles and cans, and it matters wherever your hauler collects streams separately.

The reverse problem, recyclables thrown in the trash, counts as lost material. In U.S. residential recycling, about 76% of recyclables are lost to household trash, roughly 3% are lost at MRFs, and about 21% get recycled, according to The Recycling Partnership's 2024 State of Recycling report.

Those are household figures, but in an office the same poorly placed or poorly labeled station drives both problems.

Commercial recycling also runs on a contract. Your hauler sets the accepted-materials list, may inspect loads, and can bill your business when a container misses its terms. That list can differ from the residential one in your town.

Wishcycling is a common source at work: someone drops in a padded mailer or a coffee cup hoping it's recyclable. If the item isn't on your hauler's list, it gets pulled at the sorting line or counts against the load it came in with.

What Contamination Costs the Facility

Hauler agreements can include several responses to a contaminated container: a warning tag on the cart, a contamination fee on the invoice, or a refused pickup where the entire load is sent to the landfill at the trash rate. Check your contract for the threshold and the charges.

Contamination also shows up in reporting. If your organization tracks a diversion or recycling rate, a rejected load moves that tonnage into the landfill column. For broader numbers on what businesses generate and recover, see our commercial waste statistics and trends for 2026.

Some states require businesses to recycle. California's Mandatory Commercial Recycling law, AB 341, has applied since July 1, 2012, to businesses and public entities that generate four cubic yards or more of commercial solid waste per week and to multifamily residential dwellings of five units or more, and local ordinances can set different thresholds. Requirements vary by location.

Inside the building, the cost lands on custodial staff. Someone has to re-sort a contaminated bag, double-bag a wet one, or decide it isn't worth the time and combine it with trash. Once employees see recycling and trash going into the same cart, many of them stop sorting.

At the MRF, plastic bags and film can tangle sorting equipment, and paper and cardboard need to stay dry and free of debris to be made into new paper.

Contaminated recycling can result in additional charges or rejected pickups, depending on your hauler's contract. Clear labels, suitable openings, and correctly placed stations help employees sort materials according to the program's requirements.

The Usual Workplace Contaminants, by Room

Contaminants differ by room, and so should the label and openings on each station. Acceptance of items like pizza boxes, glossy paper, coffee cups, and lids varies by program, so treat the lists below as common problem items to check against your commercial hauler's accepted-materials list.

• Break room and kitchen: Poly-lined paper coffee cups, single-serve pods (plastic, aluminum, and paper), bottles with liquid left inside, takeout containers with food residue, greasy pizza boxes, used napkins, and plastic utensils.

• Copy and print area: Loose shredded paper, laminated or glossy coated sheets, plastic sheet protectors, binder clips, and toner cartridges, which belong in a return program.

• Desks and workstations: Tissues, snack wrappers, and plastic bags used to line deskside recycling bins.

• Lobby and common areas: Takeaway cups with lids and straws attached, leftover drinks, and mixed packaging from visitors who don't know your site's rules.

• Restrooms: Paper towels are typically not part of the recycling stream (some organics programs accept them). Hygiene waste goes in a covered sanitary napkin disposal receptacle, such as the TD1000 or TD9200 we manufacture. Both keep discarded products out of view, and an internal support frame holds the liner securely open.

Some items need their own route: batteries, e-waste, ink and toner, and used gloves and other PPE. EPA's recycling guidance sends plastic bags to store drop-off and handles batteries and electronics outside the curbside bin, and batteries are a fire risk on a truck or sorting line.

EPA's analysis of lithium-ion battery fires at waste and recycling facilities identified 245 fires at 64 facilities between 2013 and 2020 that were caused or likely caused by these batteries. EPA notes the count is incomplete. Set up battery collection with a battery recycler, and use the collection system and handling procedures that recycler approves, so batteries stay out of both streams.

In each of these rooms, the choice gets made quickly by someone thinking about their next meeting.

How to Reduce Recycling Contamination With Station Design

A station steers behavior before anyone reads a word on it. Pairing, openings, labels, placement, capacity, and liners are all decided at purchase, and each can make sorting correctly take less effort than sorting wrong.

1) Pair Every Recycling Bin With a Trash Bin

A recycling bin with no trash can nearby often ends up collecting trash, because it's the only container in reach. Trash cans standing alone tend to collect bottles and paper for the same reason. Wherever you place one stream, place the other beside it.

Connected stations hold that pairing in place. Separate bins set next to each other can drift apart when custodial staff move them to clean, and units joined into one footprint can't.

The Glaro RecyclePro Value Connected Recycling Stations we distribute join two 23-gallon units in one satin aluminum station, and the Value Connected RecyclePro collection shows the other finishes.

Centralized stations, with fewer deskside trash cans, are one option to evaluate. Weigh accessibility, employee needs, and your custodial arrangements before deciding. Where deskside cans stay, pair each with a small recycling container so neither stream becomes the default.

2) Restrictive Lid Openings

The opening is often the first instruction a person sees, and it works as a physical filter as well. Match each shape to its stream:

• Round hole: Bottles and cans. A bag of trash, a takeout box, or a lidded cup won't fit easily.

• Narrow slot: Paper. Containers and food stay out.

• Mixed or multi-purpose opening: Commingled containers, where your hauler collects them together.

• Large opening or open top: Trash.

Size the trash opening generously. A person holding a balled-up sandwich wrapper at a station with a tight trash opening will look for the next hole that fits, and that's often the recycling side.

Tight openings make bulky items, such as flattened shipping boxes and large cups, awkward to get rid of. Set up a separate cardboard point near receiving or the mailroom so boxes don't get forced into the nearest container.

The RecyclePro Value receptacles we distribute come in 15- to 41-gallon sizes with lids built on these shapes: a paper slot, a 5.5" round opening for bottles and cans, a multi-purpose opening for mixed recyclables, and a large opening for waste.

3) Labels, Colors, and Images on the Station Itself

Put the label where people look: on the lid and at eye level. Use words and photos of the items people throw away at your site, like the cup from the coffee shop downstairs or the packaging your deliveries arrive in. A generic chasing arrows symbol doesn't tell anyone what goes in.

Limit the "no" side of the label to three items: the contaminants you pull out of that station most often.

Bin colors are a common convention: blue for recycling, green for organics or compost, gray or black for landfill. California builds them into its organics rules. Under SB 1383 regulations, Title 14 of the California Code of Regulations (14 CCR) §18984.9 requires commercial businesses to provide recycling and organics containers wherever they provide disposal containers for customers (restrooms excepted), with a body or lid matching the colors of the local collection service or labels that meet §18984.8. Section 18984.10 also requires businesses to give employees, contractors, tenants, and customers access to an adequate number of properly colored or labeled containers, and local jurisdictions can adopt stricter rules.

CalRecycle's container color and labeling guidance explains that the color rule applies to the container's exterior. Under 14 CCR §18984.9(d), a business doesn't have to replace functional containers that don't meet the rules, including containers bought before January 1, 2022, until the end of their useful life or January 1, 2036, whichever comes first.

Whatever colors you use, keep them the same on each floor, and pick one word for the trash stream (trash, landfill, or waste) for each station. A habit formed in the break room then carries into the lobby. Permanent printed messaging outlasts stickers, which peel and get swapped between bins.

The Deluxe stations we distribute, for example, take pre-set recycling messages such as BOTTLES & CANS, MIXED RECYCLING, and TRASH.

For the signage rollout and introducing stations to staff, see our guide to setting up an office recycling program.

4) Placement and Capacity

Put stations where waste is created: the break room, copy room, conference rooms, and lobby exits. Use one station design throughout the building, and skip lone bins in corridors, which collect whatever people are carrying.

Size each stream from what you see in the bins. An overflowing recycling container pushes the extra into the trash or onto the lid. Print areas usually need more paper capacity, and kitchens need more room for containers. Set service frequency by how fast each container fills.

Keep stations out of walking paths. Under the 2010 ADA Standards, an accessible route generally needs a clear width of at least 36 inches (§403.5.1), and a station placed along the route shouldn't narrow it below that. The facility or installer makes that determination for the final layout.

For a lobby or break room that needs three streams in one footprint, the Glaro RecyclePro Deluxe 3-unit modular station we distribute holds 48 gallons across three 16-gallon units, with satin brass funnel lids and a custom base, and is made in the USA. For sizing trash receptacles by environment, see how to choose a commercial waste receptacle.

5) Lids, Liners, and Servicing

Clear liners on the recycling side and dark liners on the trash side let custodial staff see contamination before bags are combined on a cart. That bag is the last check before material leaves for the dock. Some haulers want recyclables loose, so confirm whether bags can go out with the material or need to be emptied first.

A lid that hides the liner keeps the station looking clean, and a tidy station often gets more careful use than one with a bag edge hanging over the rim. Bags sized to the can stay put and don't bunch.

On the RecyclePro Value receptacles we distribute, the recommended custom-fit bag folds over the receptacle body, and the cover's extra-long overlap conceals the bag and holds it in place, which keeps the station neat and makes liner changes easier for custodial staff.

Rigid inner liner cans can make emptying quicker than lifting a loose bag out of a cabinet. Glaro offers inner liner options that provide a neat, removable container for easier servicing and waste removal.

What's included depends on the model. RecyclePro Value Connected stations use the concealed-bag design above, so no inner liner can is included; optional plastic inner liner cans are available upon request. Deluxe Connected models such as the 3-unit 48-gallon station include removable plastic inner liners.

Station Setups for Common Office Spaces

Build each station around the streams your hauler collects. With single-stream collection, a multi-stream station adds sorting the hauler undoes at the truck, and a two-stream station (recycling and trash) is enough. The setups below assume your hauler collects paper and containers separately.

Checking Whether the Design Is Working

Lift the lids once a week and log a photo of each station by location. Track one number: the share of stations with visible contamination, broken out by room type.

Your hauler's contamination tags or reports are the outside check. When a station keeps failing, change the opening type first, then the label, the placement, and the capacity. Retraining comes after those, since staff see the station daily and a refresher rarely.

Our office recycling program guide covers the full waste audit and hauler review.

Turning a Contamination Tag Into a Station Spec

Start with the room that produced the tag or the bag. Write down which streams your hauler collects, the three items you find most often in the wrong container there, and how much floor or wall space the station has to fit. Those three answers give you the opening types, the label content, and the footprint.

A connected two- or three-stream unit suits break rooms and lobbies, a slot-and-trash pair suits the copy room, and a half-round dual unit fits a tight wall.

Buyer Checklist for Recycling Stations

Before you request a quote, settle these for each station:

• Accepted materials: what your commercial hauler's list takes and excludes

• Number of streams: one, two, or three, plus organics if your program composts

• Openings: round, slot, multi-purpose, or large, matched to each stream

• Labels: words and photos of your site's items, one trash term, consistent colors

• Capacity: gallons per stream, based on how fast each container fills between service rounds

• Finish: matched to the room and consistent across floors

• Liner requirements: bag size, clear or dark, and whether an inner liner can is included or optional

All Glaro products are custom-made to order, so include them early in your project planning. Allow approximately 14 business days for production, plus shipping time, and confirm dimensions, finishes, and quantities before ordering. Color chips are available to assist with finish selection.
