Where Old Wetsuits Go: A Million Suits a Year, and Almost Nowhere to Put Them

Open the shed. There is probably a wetsuit in there you have not worn in two years. Slightly baggy, one dead seam, still too expensive looking to throw out.

You are not alone, and the bin is not the answer. Here is what actually happens to old suits, and what you can do with yours.

The scale

Circular Flow, a company working on neoprene recovery, estimates that around 10,500 tonnes of wetsuits reach end of life globally every year. They get there by taking a market of roughly 7.3 million units, an average suit weight of 1.5 kg, and a five year lifespan. That works out at more than a million wetsuits a year.

Other estimates put the figure at 8,380 tonnes. Neither includes boots, gloves, hoods or vests, and neither counts the far larger volume of neoprene used outside water sports.

Nearly all of it is landfilled. Less than 1 percent of textile waste globally gets recycled, and wetsuits are among the hardest items in that category.

The UK, which tracks this better than most, sends more than 380 tonnes of neoprene to landfill or incineration each year, over half of it from Cornwall. Australia has no equivalent number. Nobody has counted, which tells you roughly how much attention the problem gets here.

Why nobody recycles wetsuits

Three problems, and each one is genuinely hard.

The suit is a laminate. Neoprene foam is bonded to a nylon or polyester jersey across its entire surface. That bond is what stops the foam tearing when you pull the suit on. It also means you cannot separate the rubber from the fabric without destroying both. No commercial process does this at a cost anyone would pay.

The rubber cannot be remelted. Polychloroprene is a thermoset. Heating it does not return it to a workable state the way heating a plastic bottle does. It can be shredded into crumb and used as filler in gym mats, carpet underlay and playground soft fall. That is downcycling. The material goes down a grade and never comes back.

The logistics do not work. Wetsuits are bulky, heavy and spread across thousands of garages up and down the coast. Collecting them costs more than the recovered crumb is worth. Freight is what kills most schemes before they start.

What is being tried

Progress is real, and small.

Circular Flow operates a recovery facility in Bulgaria. The University of Plymouth has been funded to assess whether a UK neoprene recycling plant would be viable. In Cornwall, The Wave Project and waste company SUEZ have put wetsuit collection bins in council waste centres, with suits going to a repair workshop in Newquay, cleaned, mended and resold at £20 to £60 against an average new suit price of £420. Anything beyond repair becomes bags, mats and pillows.

That last model is the one worth watching, because it puts repair first and recycling last. That order matches the actual environmental maths.

What to do with your old suit, in order

1. Get it repaired. This should be the default and it usually is not. Most suits that get retired have one specific failure: a split seam, a blown zip, a worn knee, a fin cut through a panel. The rest of the suit is fine. A repair costs a fraction of a replacement and keeps 1.5 kg of neoprene out of the ground.

WRAP found that extending a garment's active life by nine months cuts its carbon, water and waste footprints by 20 to 30 percent. Wetsuits do better than average on this, because nearly all of a suit's footprint is created before you ever put it on.

2. Pass it on. A suit that no longer fits you fits someone else. Boardriders clubs, nippers, surf schools and local buy and swap groups all move second hand suits constantly. Rinse it, dry it, be honest about its condition.

3. Repurpose it. Old neoprene makes good drink coolers, tool rolls, kneeling pads for the garden, dog coats and boot liners. Panels from a dead suit also make ideal patch material, which is exactly what we use ours for.

4. Keep it as a spare. A tired suit is still a suit. It works for a mate who is having a go, for a cold shore dive, for anything where you would rather not wreck the good one.

5. Landfill, last. If a suit is delaminating across multiple panels and the foam has gone hard, it is finished. That is the honest end of the line in Australia right now.

What we do with suits beyond saving

When a suit comes to us and it is genuinely past repair, we say so. We do not invoice people for work that will not hold.

We then ask whether we can keep it. Salvageable panels come off and go into our patch stock, so the next fin cut gets fixed with neoprene that has already been made rather than neoprene that has not. It is a small loop, and it is the only one available to us at the moment.

Frequently asked questions

Can you recycle wetsuits in Australia? Not currently. There is no kerbside or commercial neoprene recycling stream here. Repair, resale and repurposing are the practical options.

How long does neoprene take to break down in landfill? Estimates run into the hundreds of years. The material was designed to resist water, salt and UV, which is exactly what makes it persistent in the ground.

Is it worth repairing an old wetsuit? Usually yes, if the foam is still supple and the damage is localised. Send a photo and we will tell you either way.

What can I make from an old wetsuit? Drink coolers, tool rolls, dog coats, kneeling pads, boot liners and patch material. The neoprene stays useful long after the suit stops keeping you warm.
