Why Mattress Recycling Matters in Sydney (And What Happens to Your Old Mattress)

Every year Australians send millions of mattresses to landfill — yet most of a mattress can be recycled. Mattresses don't compact in landfill, and the steel, foam and timber inside take decades to break down. Here's what actually happens when one is recycled instead.

What's inside a mattress?

A standard mattress is a stack of separate, individually recyclable materials that just happen to be sewn together:

• Steel springs — baled and melted down for re-manufacture. This is the highest-value component by a distance.
• Foam layers — shredded and re-bonded into carpet underlay, acoustic insulation and gym matting.
• Timber frame — chipped into mulch, particleboard feedstock or biomass fuel.
• Fabric and fibre — recovered for industrial filler and padding where the material quality allows.

In landfill, all of that is wasted at once. Recycled properly, the materials re-enter the economy and displace virgin resources.

What happens step by step

1. Sorting. Mattresses are graded by type — innerspring, pocket-spring, memory foam, latex — because each is dismantled differently.
2. Cutting. The outer cover is slit and peeled away from the core.
3. Separation. Foam and fibre layers are pulled off the spring unit, mostly by hand, because no machine yet does it cleanly.
4. Spring recovery. The steel unit is compressed, baled and sent to a metal recycler.
5. Foam processing. Foam is shredded, cleaned and re-bonded into sheet product.
6. Timber processing. Frames are de-nailed and chipped.

It is deliberately labour-intensive work, which is the honest reason mattress recycling costs money rather than paying for itself.

Why a mattress is so bad in landfill

Mattresses are the classic example of a product landfills hate. They're mostly air, so they consume enormous volume for very little mass. They don't compact — the spring unit springs back, and it can damage compactor equipment. They trap pockets of air and water in the fill, which interferes with how a landfill cell settles and drains. And they take decades to break down, if they ever really do.

Some landfills now charge a penalty rate for them, or refuse them outright, precisely because of the volume and equipment damage.

Sydney's mattress problem

Sydney generates a huge volume of mattress waste, and it's growing for three compounding reasons: population growth, an unusually mobile rental market, and cheap mattress-in-a-box brands that have cut the average replacement cycle dramatically. A mattress that cost $400 online and lasted four years doesn't feel worth transporting or repairing.

Council collections can't always absorb the volume, so mattresses end up on nature strips, in laneways and on vacant blocks. Illegal dumping creates hazards and costs councils — and ultimately ratepayers — millions to clear.

Memory foam and mattress-in-a-box

Worth knowing if yours is a newer foam mattress: they're recyclable, but differently. There's no steel to recover, so the value sits entirely in the foam, which gets shredded into underlay. All-foam mattresses are lighter to handle but bulkier to store, and they can't be compressed back into the box they arrived in. We take them either way at the same price.

How Recycle Corp handles it

We make the responsible option the easy one: book online, arrange for the mattress to be placed outside at the kerbside before collection, and we collect across Sydney, Monday to Friday, 6am–4pm — often the same day if you book before noon, otherwise within 24–48 hours on service days. Every mattress we collect goes to recycling. Our flat $80 fee covers kerbside pickup, transport and full recycling — any size, any condition.

We collect mattresses, sofas and lounges, appliances (fridges, freezers, washing machines and TVs), e-waste and cars. That's deliberate — they're the streams that can genuinely be recovered. Here's the full picture.
