Wood or plastic: it comes down to whether you get it back
The comparison is usually framed as a materials argument. It is really a logistics argument, and the deciding number is how many trips the pallet survives under your control.
Request pricing
Everything marked with a star is required. The rest helps us quote faster.
Wooden pallets cost $5.50–$13.50 and are cheap to repair; plastic pallets cost $18–$160, are hygienic, washable and exempt from ISPM 15, but rarely repairable.
Plastic breaks even against wood at roughly 35–60 trips in a closed loop. If your pallets leave your control and do not come back, wood wins decisively on both cost and carbon.

| Repairable | Yes, $1.75 – $4.50 | Yes | Rarely |
| Hygiene | Porous, cannot sterilise | Porous | Washable, sterilisable |
| Dimensional consistency | ±10 mm | ±5 mm | ±2 mm |
| ISPM 15 | Required | Required | Exempt |
| Fire behaviour | Combustible | Combustible | Combustible, melts and flows |
| Cold chain | Good to any temperature | Good | Some resins embrittle below −20 °C |
| End of life | Repair, reuse, mulch | Same | Regrind, where a route exists |
| Typical lives | 6 – 8 with repair | 8 – 12 with repair | 40 – 120 |
The break-even arithmetic
Cost per trip is the only fair comparison, and it depends entirely on trip count. Take a $10.75 recycled hardwood pallet against a $52 rackable plastic pallet, with wood repaired once at $3 mid-life.
| Trips completed | Recycled wood | Plastic | Winner |
|---|---|---|---|
| 1 | $10.75 | $52.00 | Wood, decisively |
| 5 | $2.75 | $10.40 | Wood |
| 8 (wood's practical limit) | $1.72 | $6.50 | Wood |
| 20 | n/a — buy again | $2.60 | Plastic |
| 40 | n/a | $1.30 | Plastic |
| 80 | n/a | $0.65 | Plastic, decisively |
Where each genuinely wins
Wood wins when
- The pallet leaves your control on outbound freight.
- Upfront cost or cash flow matters.
- Loads are irregular and pallets get damaged.
- You have access to a recycler who repairs rather than grinds.
- You want the lowest carbon footprint per trip in an open loop.
Plastic wins when
- The environment demands washdown or sterilisation.
- The loop is closed and tracked.
- Automation needs millimetre consistency.
- You export frequently and want to sidestep ISPM 15 entirely.
- Weight matters — air freight or manual handling.
Many operations end up running both: plastic inside the plant where hygiene and automation matter, wood outbound where the pallet will not return. That is not indecision, it is the correct answer.
The carbon question
This is closer than either industry's marketing suggests, and it turns on the same variable as the cost case. Wood carries low embodied carbon and sequesters carbon while in use, but a shorter life. Plastic carries high embodied carbon — most published figures put a new HDPE pallet somewhere in the range of 90–130 kg CO₂e — amortised over many more trips.
Per trip, a repaired recycled wooden pallet is very hard to beat: roughly 0.6–0.9 kg CO₂e depending on how the repair lumber is counted. A plastic pallet reaches similar territory only after several dozen circuits, and immediately loses the comparison if it is lost early or if no regrind route exists at end of life.
We sell both and we will not pretend the answer is always wood. But if you are choosing plastic for environmental reasons rather than hygiene or automation reasons, look hard at your real-world trip count first. The full factor list is on our methodology page.
Hygiene, regulation and the food-safety question
This is where the argument for plastic is strongest and most often misstated. Being precise matters, because the wrong decision here is a regulatory problem rather than a cost problem.
| Environment | Wood | Plastic | Notes |
|---|---|---|---|
| General warehousing | Yes | Yes | Cost decides |
| Secondary food packaging | Yes | Yes | Dry, clean wood is widely accepted |
| Open food handling | No | Yes | Porous surfaces cannot be sanitised |
| Washdown areas | No | Yes | Wood absorbs and holds water |
| Pharmaceutical | No | Yes | Documented cleanability required |
| Cleanroom | No | Yes | Particulate shedding |
| Cold storage, stable | Yes | Yes | Check resin cold limit |
| Cold storage, cycling | Marginal | Yes | Moisture cycling halves wood life |
| Export | Yes, with ISPM 15 | Yes, exempt | Plastic sidesteps the standard |
The loss-rate calculation nobody does
Every plastic pallet business case we have seen assumes a return rate. Almost none of them measure it afterwards. It is the single variable that decides whether the case was right.
| Annual attrition | Effective life | Trips delivered | Cost per trip | vs. $10.75 wood at 5 trips |
|---|---|---|---|---|
| 0% | 5 years (wear-limited) | 120 | $0.43 | Plastic wins comfortably |
| 3% | ≈ 4.2 years | 101 | $0.51 | Plastic wins |
| 8% | ≈ 3.1 years | 74 | $0.70 | Plastic wins |
| 15% | ≈ 2.1 years | 50 | $1.04 | Plastic wins |
| 30% | ≈ 1.1 years | 26 | $2.00 | Roughly level |
| 50% | ≈ 0.7 years | 17 | $3.06 | Wood wins |
| Open loop (100%) | 1 trip | 1 | $52.00 | Wood wins decisively |
The break-even sits somewhere around 30% annual attrition. That sounds like a wide margin of safety until you realise that open-loop shipping is effectively 100% and that most operations have never measured which of their loops is which.
How to measure it
Mark 200 pallets with a visible number, release them into the loop, and count how many are still in circulation after twelve months. It costs an afternoon and it is the only number that makes a plastic business case defensible.
Running both, deliberately
Most operations that get this right end up with two pools, and it is not a compromise — it is the correct answer to two different problems.
Plastic inside
Closed internal loops, washdown areas, automation and anywhere hygiene is regulated. High unit cost amortised over many controlled trips.
Wood outbound
Anything leaving your control. Cheap, repairable, recyclable at the far end by whoever receives it, and no tracking burden.
A transfer point
The one thing that needs designing: where product moves from a plastic pallet to a wooden one. Usually a transfer station or a slip sheet at the despatch bay.
- Colour-code the two pools so nothing plastic leaves the building by accident.
- Put the transfer point at despatch, not at goods-in, so the plastic never reaches a trailer.
- Count the plastic pool quarterly. Attrition is a leak, and leaks are cheapest to fix early.
- Buy wood on a programme, which is where the pricing is and where the reporting comes from.
- Tell your recycler about both. We buy sound plastic back too, and cracked units go to resin rather than landfill.
