If you’ve ever walked into an office kitchen and seen a commingle bin overflowing with coffee cups and chip packets, you’re not alone. Getting the commingle bin setup right is one of the most common questions we hear from small businesses, and it’s genuinely trickier than it looks. A workplace kitchen seems simple enough on the surface, but it’s actually one of the highest-risk spots in any office for waste contamination. People are in and out quickly, juggling a lunch container in one hand and a coffee cup in the other, and they’ll go straight for whichever bin is closest rather than the right one.
That’s the problem this guide is here to help you fix. A well-set-up commingle bin station in your kitchen helps your business meet its state and council environmental obligations while making the sustainable choice the natural one for your team. The goal is a setup that largely looks after itself, without you needing to remind staff about recycling every other week.
We’ll cover everything from picking the right bin for your kitchen layout and understanding what actually belongs inside it, through to getting your team on board and staying on the right side of Australian waste regulations. We’ll also show you how Waster fits into the picture once your internal setup is sorted.

Choosing the Right Commingled Recycling Bin for Your Kitchen Layout
The physical bin you choose shapes everything else. Get this part wrong and even the best signage in the world won’t save you.
When it comes to capacity, think about foot traffic rather than headcount alone. A 20-person office with one shared kitchenette might get by with a 60L or 80L commingled recycling bin emptied a few times a week. A larger workplace with several break-out kitchen areas might need 120L bins in each zone. If the bin is overflowing before the next collection, it’s too small. Overflow is one of the quickest ways to end up with recyclables tipped onto the floor or stuffed into general waste out of pure frustration.
Lid design is worth paying attention to. A commingled recycling bin with a restricted aperture, like a slot-style opening rather than a fully open top, does two things well. It stops the bin being used as a catch-all for everything, and it slows people down just enough to make them think before tossing something in. Open-top bins are much easier to contaminate because there’s nothing to create even a moment’s pause.
Go for a bin made from durable materials that are easy to wipe down. Kitchens are wet, often sticky environments, and a bin that holds odours or shows stains will get avoided or generate complaints fairly quickly.
How about placement?
On placement, the rule is straightforward: your commingled recycling bin needs to sit right next to the general waste and organics bins, not across the room or tucked away in a corner. When recycling feels even slightly inconvenient, most people, even those who genuinely care about the environment, will default to the nearest bin. This is what’s sometimes called convenience dumping, and it’s the leading cause of contamination we see in office kitchens. Line the bins up side by side, at the same height, facing the same direction. Take the thinking out of it at the point of disposal.
What Can and Can’t Go into Commingled Waste Bins?
This is where most workplace kitchens come unstuck. Not because people don’t care, but because nobody has actually told them clearly what goes where.
Generally accepted in commingled waste bins
- Rigid plastic containers and bottles, such as yoghurt tubs, sauce bottles and takeaway containers, as long as they’re free of food residue
- Aluminium and steel cans
- Glass bottles and jars
- Clean paper-based cartons, like empty milk or juice cartons
Common kitchen items that don’t belong
- Soft plastics, including cling wrap, chip packets and bread bags
- Anything with food residue still inside, such as a yoghurt tub that hasn’t been rinsed out
- Coffee cups, which are lined with plastic and not accepted in most standard commingled streams
- Paper towels and napkins, especially when wet or greasy
- Greasy pizza boxes or oily takeaway packaging
- One greasy pizza box or a half-full coffee cup can be enough to contaminate an entire bin load, and that has real financial consequences we’ll cover in the next section.
Clear signage carries a lot of weight here. In Australia, commingled recycling bins use a yellow lid as the standard colour code. Pair that lid colour with simple, image-based signage placed directly above or on the bin, at eye level. Word-heavy signs get ignored in a busy kitchen. A quick visual showing a bottle, can and jar with a tick alongside a coffee cup with a cross does far more work than a detailed list of instructions ever will.
Simplifying Commingled Waste Recycling with Staff Education
The right bins and signage get you most of the way there. The final stretch comes down to behaviour, and that’s where contamination either gets sorted or keeps getting worse.
The single habit worth genuinely drilling into your team is the empty-and-rinse rule. A container with sauce, milk residue or food scraps still inside doesn’t just contaminate itself. It can contaminate everything else in the bin around it. This isn’t about a thorough wash under hot water. A quick rinse and shake before it goes in is enough to make a real difference.
A few ways workplaces build this habit without it feeling like a chore:
Run a five-minute briefing when the new bins are set up, rather than relying on an email that gets buried in the inbox
- Put up simple, visual posters near the bins themselves, not pinned to a noticeboard in the hallway
- Nominate a sustainability champion on each floor or team who can answer questions and keep an eye on things day to day
- Do a quick audit every month or so, check the recycling bin before collection and flag anything that shouldn’t be there
That last point is more effective than most businesses realise. If contamination is creeping up, staff generally don’t know about it unless someone tells them. A short note on the kitchen noticeboard, something like “we found a few coffee cups in recycling this week, here’s why that matters,” tends to do more for long-term commingled waste recycling habits than any poster campaign on its own.
Navigating Australian Compliance and Waste Stream Regulations
Here’s the part that turns commingle bin setup from a nice idea into something with genuine financial and legal weight behind it.
Waste regulation in Australia sits primarily at the state and local council level, and the rules are tightening across the board. In NSW, the EPA’s Bin Trim program offers rebates for businesses that upgrade bin infrastructure and signage. From July 2026, NSW is also phasing in mandatory food waste separation for larger commercial premises under its FOGO business mandate, starting with sites generating the equivalent of 16 or more 240-litre bins of waste per week. In Victoria, the Circular Economy (Waste Reduction and Recycling) Act 2021 provides for mandatory sorting of recyclables and organics for certain businesses, with Recycling Victoria overseeing the rollout. Queensland’s framework leans more on landfill levies and council-level requirements, but the direction is the same everywhere: better separation at the source, or wear the financial consequences.
Consequences?
And those consequences are real. Contamination across Australia’s recycling stream runs at roughly 14 per cent nationally, according to the National Waste Report. Kitchen and break-room bins tend to be among the worst offenders, mostly because of food residue and coffee cups. When a load is contaminated beyond what a Materials Recovery Facility can process, waste collectors can reject it outright, and that rejection typically means a fee passed straight back to the business. In the worst case, a contaminated bin gets redirected to landfill, meaning you’ve paid for a recycling collection and ended up with a landfill levy for your trouble.
There’s also a supply chain angle worth knowing about. Clean, well-separated commingled material has real market value. It gets processed and sold back into manufacturing as recycled glass, aluminium and plastic. Contaminated loads often have no buyer at all. Properly separating your kitchen waste isn’t just a compliance exercise. It helps protect the market for recycled materials more broadly, which is worth something too.
Why Waster is the Smart Choice for Your Workplace Commingled Recycling Bin Setup
Once your internal setup is right, with bins sorted, signage up and staff on board, you need a collection partner who won’t undo all that effort with a clunky contract or a service that can’t keep up as your office evolves.
Here’s why small businesses choose Waster:
- Flexible, no lock-in contracts. We run on 30-day agreements rather than the multi-year contracts most of the industry still defaults to. If your office grows, downsizes or moves locations, you’re not locked into a bin size or service frequency that no longer fits.
- Transparent, flat-rate pricing. No hidden fees, no surprise landfill levy increases buried in the small print. Facilities teams can budget for kitchen waste the same way they budget for any other recurring cost.
- Bin sizes for any kitchen, nationwide. From 120L and 240L wheelie bins for a smaller office kitchen through to 660L and 1100L options for high-density workplaces, we service major metro areas right across Australia.
- Support that goes beyond collection. We provide downloadable bin labels and educational signage kits, plus online portal access so you can track collection schedules and pull waste reports when you need them. That comes in handy whether you’re reporting on sustainability internally or to a building landlord.
Sorting out the kitchen is the internal half of the job. Finding a reliable, cost-effective pickup partner is the other half, and that’s where we come in.

Frequently Asked Questions
Do you have the same questions as the ones below? Waster answers all of the below:
Are books allowed in the commingled recycling bin?
No. Books are made from mixed materials including paper, glue and sometimes hard covers, and these don’t process well through a standard Materials Recovery Facility. Books in good condition are better off donated. Damaged ones can usually go through a dedicated paper recycling stream, or into general waste if they’re beyond use.
What can go in a commingled bin?
Rigid plastic containers and bottles, aluminium and steel cans, glass bottles and jars, and clean paper-based cartons like empty milk or juice cartons. Everything should be empty and free of food residue before it goes in.
Can takeaway coffee cups go into the workplace commingled recycling bin?
In most cases, no. Standard takeaway coffee cups have a thin plastic lining that most commingled recycling facilities can’t separate from the paper, so they belong in general waste. The exception is if your workplace has set up a dedicated coffee cup recycling program, which some specialist providers offer.
Do employees need to wash containers before putting them in the commingled bin?
Not a full wash, but a quick rinse to remove food or liquid residue makes a significant difference. A container with sauce or milk still inside can contaminate everything around it in the bin, which can put the whole load at risk of being rejected or redirected to landfill.
What happens if a commingled recycling bin gets contaminated with general waste?
If contamination levels are too high, the waste collector may reject the entire load and charge a rejection fee. Alternatively, the whole bin can be redirected to landfill rather than recycled. Either way, you’ve paid for a recycling service and got a landfill outcome instead. A solid bin setup and a consistent staff routine are the most reliable ways to avoid that happening.
