Source-Separated vs Commingled Recycling

First agree what the labels mean. If both quotes use “single-stream” and “commingled” for the same mixed-material service, there may be no meaningful difference to compare.

The facts behind the comparison

City of Melbourne’s bin guidance distinguishes mixed recycling from separate cardboard and other streams, with acceptance limits for each. That local guidance illustrates why a material list is more useful than a label. Source: City of Melbourne — Waste Bin Permits: Information Pack.

What the two labels actually mean

“Commingled” consistently means one bin taking several recyclable materials together, separated afterwards at a materials recovery facility. “Single-stream” is the unreliable word: in much of the industry it describes that same mixed bin — a single stream of recyclables — while in Australian commercial quoting it is often used for the opposite arrangement, one material per bin with its own destination.

So the first question to a provider is not which one they recommend. It is: which materials does each proposed bin accept, and where does each one go? Two quotes using opposite words can describe the same truck, the same facility and the same outcome.

Separate material streams: what changes

One material per container, each with its own destination.

  • Material condition. A dedicated container keeps one material away from the others, which is what acceptance standards are written around. Ask what standard applies to each stream.
  • Clearer rejection rules. When a load fails, it is obvious which stream and which behaviour caused it.
  • More containers. More floor space, more collection movements and more lines on the invoice. This is the cost that has to be weighed against any lower processing charge.
  • More for staff to get right. Signage, induction and a bin placed where the material actually arises, not where there happens to be room.
  • Commercial terms per stream. Rebates, processing charges and minimum volumes are negotiated stream by stream. Get each one in writing.

One combined bin: what changes

One container taking the accepted recyclables together, sorted after collection.

  • One instruction for staff. The simplest arrangement to run during a busy shift, which matters more than it sounds.
  • Less space and fewer movements. One container and one collection instead of several.
  • Acceptance is narrower than people assume. The bin takes a specific list, in a specific condition. Items outside it are contamination, not optimism.
  • Rejection risk sits on the whole bin. One load, one decision. Ask what a rejected load costs and how you are told.
  • Sorting happens downstream. What is recovered depends on the facility, so if recovery is being reported, ask what evidence is specific to your load.

What a commingled bin accepts

Acceptance is set by the receiving facility, so your own collector’s list is the one that governs. As an operator example, Cleanaway lists common recyclable containers as “glass bottles and jars, aluminium cans, steel cans, and hard plastic containers that are empty, clean, and dry”, together with “packaging made from a single recyclable material or with minor mixed components such as plastic bottles with lids, metal jar lids, and cardboard beverage sleeves”.

The same source describes what happens next: collection in dedicated vehicles, transport to the materials recovery facility, sorting where “a combination of automated machinery and manual sorters remove any non-recyclable items and separate the recyclables into different streams”, then delivery to recyclers. Source: Cleanaway — Commingled services for businesses and councils.

That is one operator’s arrangement, not a national standard. Ask your provider for their accepted list in writing, including whether glass is accepted in the combined bin at your site and what happens to a load that contains material outside the list.

What actually drives the cost

Compare total service cost for the configuration your site can actually run, not a rate per bin. Ask each provider to separate:

  • Container rental or hire for every container in the proposal, not just the recycling one.
  • The collection charge per container and the minimum number of collections per period.
  • Any processing, sorting or gate charge, and the basis it is calculated on.
  • Any rebate or credit, the quality standard it depends on and what happens when a load misses it.
  • Contamination and rejected-load charges, and how a rejection is notified and evidenced.
  • What the change does to the general waste service, because that is usually where the offsetting saving is — or is not.

A separation proposal that adds three containers and three collection runs has to beat the combined arrangement on the total, including the general waste line. Sometimes it does. Run it on your own numbers.

Which setup usually fits

  • Separate streams tend to suit sites with steady volumes of one or two dominant materials — a warehouse with cardboard, a bar with glass — and the space to hold a container for each.
  • A combined bin tends to suit sites where recyclable volume is modest and mixed, space is tight, or staff turnover makes a complicated arrangement unreliable.
  • Many sites end up with both: one dominant material separated out, everything else combined.

None of this guarantees a higher recovery rate or a lower cost. It is a starting point for the quotes, not a verdict.

Before you decide

  1. Get both providers to write out their accepted materials.
  2. Check whether the proposed services are actually different.
  3. Trial staff instructions using examples from your own waste.
  4. Review contamination feedback and downstream acceptance after the change.

Frequently asked questions

What is the difference between single-stream and commingled recycling?
In everyday use, commingled means one bin that accepts several recyclable materials together, sorted afterwards at a materials recovery facility. Single-stream is used two ways: sometimes for that same mixed bin, and sometimes for the opposite arrangement, where each material has its own dedicated bin and destination. Because the words are used inconsistently, compare the accepted material list and the destination for each proposal rather than the label. If both quotes describe the same mixed service, there may be no difference to compare.
What can go in a commingled recycling bin?
Ask your own collector, because acceptance is set by the receiving facility rather than by the material in principle. As an operator example, Cleanaway describes common recyclable containers as glass bottles and jars, aluminium cans, steel cans, and hard plastic containers that are empty, clean, and dry, along with packaging made from a single recyclable material or with minor mixed components such as plastic bottles with lids, metal jar lids and cardboard beverage sleeves. That is one operator’s list, not a universal menu, and the empty, clean and dry condition applies throughout.
Does commingled recycling actually get recycled?
Material in a commingled bin goes to a materials recovery facility. Cleanaway describes the process as collection in dedicated vehicles, transport to the facility, sorting where a combination of automated machinery and manual sorters remove any non-recyclable items and separate the recyclables into different streams, and then delivery to recyclers. What is recovered depends on what went in and on the facility, so if you need to report recovery, agree the measurement basis and the evidence you will receive before you change anything.
Can my business earn money from source-separated recycling?
Sometimes, and it is quoted account by account rather than published. Whether a clean separated stream attracts a rebate, a lower processing charge or no benefit at all depends on the material, its condition, the volume and the market at the time. Ask for it in writing as part of the quote, with the quality standard the price depends on and what happens when a load fails it. Do not build a budget on a rebate figure taken from an article.
How do I set up separated recycling in my workplace?
Start from the materials you actually generate and where they arise, then check that each proposed stream has an accepted destination and enough safe space for its container. Get both providers to write out their accepted materials, and trial the staff instructions using examples from your own waste before committing. Label bins with words as well as colour, cover the arrangement in staff induction rather than a one-off briefing, and review contamination feedback and downstream acceptance after the change.
