Recycling 40 x 40 plastic pallets: who retires them and how a load is sorted

Last reviewed Nov 12, 20269 stages
The short answer

A retired 40 x 40 in plastic pallet is sorted by resin, colour and condition, then reused or ground into regrind. Plastic availability is not sourced here.

Got a load like this?

Five questions and a photo. We say what we think happens next once the pallets have been seen.

What a 40 x 40 in pallet is

The sixth most produced pallet size in the US across all materials, per Wikipedia. Plastic availability for this size is not sourced here, so treat any claim about it with care.

Who retires it

Dairy, paint and specialty product shippers who run square pallets. These sizes are retired when a customer changes the standard.

How the sort goes

Describe what you have rather than relying on the size name. A 40 x 40 may be nestable or solid. Check the resin code and any maker mark.

What a 40 x 40 in load needs to describe

Send a close-up of a runner, because unusual sizes are easier to identify from the part. Then the count, the resin, the colour, any marks and the ZIP.

Size matters for the trailer. Deck area here is 11.1 sq ft, and Euro 48 x 32 is next closest at 10.3 sq ft, so check you have not got the two mixed together.

Reading the measurements

The deck is 40 inches by 40 inches, which is 1016 by 1016 millimetres, 1,600 square inches or 1.032 square metres. The diagonal is 56.6 inches. In shape it is square, with a long side 1.00 times the short one.

A tape across the diagonal, 57 inches or 1437 millimetres, is a quick check that a pallet is the size you think it is.

Edges and corners of the 40 x 40 deck

Walk the 13.3 feet of edge on a 40 x 40 in pallet and look at the corners first. Rounded, chipped or cracked corners are where a 40 by 40 deck gives up, and a photograph of each of the four corners tells a buyer more than a paragraph. Sound corners suggest reuse; broken ones suggest regrind.

Describing a 40 x 40 lot

A 40 x 40 in lot is described by count, resin, colour and condition, with a note on whether it sits banded or loose. Add the pickup ZIP, and photograph one underside so the maker marks and any metal are visible before anything is quoted.

Where 40 x 40 piles turn up

Dairy, paint and specialty product shippers who run square pallets. The size is the sixth most produced in the US across all materials, but the sources do not give a plastic share, so we say nothing about how many are plastic.

Photograph the part

Odd square sizes are easiest to identify from a close-up of a runner or a corner. Put a tape on the deck in the picture. A recycler can then tell a 40 x 40 from a 42 x 42 without a visit.

Terms on this page

Reuse cycle
One trip out with a load and back again. Some pallets are rated for a number of them.
Regrind
Plastic ground from used or scrap parts into flakes for moulding again.
Nestable
Empty pallets stack inside one another, cutting empty storage space by up to 75 percent.
Resin code
The number inside the triangle on a plastic part. HDPE is 2, PP is 5.
Resin identification code
Number on a plastic part for the resin, which does not itself say whether it is recyclable.
Deck
The flat surface that carries the load. A pallet may have a top deck, a bottom deck or both.
Runners
Bottom rails that touch the floor or rack and carry the load.
Ownership check
Our first step with any pallet that carries a name, logo, tag or colour that suggests another owner.
Trailer fill
How much of a trailer a load takes: a quarter, half or full. It sizes the freight job.
Euro pallet
800 x 1200 mm footprint.
Footprint
The length and width of a pallet’s deck, for example 48 x 40 inches.

Questions people ask

What is a 40 x 40 in pallet used for?

Rank: Sixth most produced pallet size in the US (all materials).

Can I recycle 40 x 40 in plastic pallets in bulk?

Yes. Describe the count, the resin and the condition, and say how the pallets are stacked. We say what we think happens next.

How do I tell 40 x 40 in from a nearby size?

Measure the deck. This one is 40 x 40 in, 1016 x 1016 mm. Euro 48 x 32 is 10.3 sq ft, against 11.1 here.

Is a 40 x 40 the same as a 48 x 40?

No. A 48 x 40 is 8 inches longer on one side. Measure both ways before you count.

Why do square pallets get retired?

Usually because a customer changes its standard to 48 x 40 or a different square size.
