Which pallets belong here
EPAL's classification lists the faults that make a Euro pallet not fit for use: missing or broken parts, a block twisted out by more than about 1 cm, visible nail tips, contamination such as oil, paint, mould or odour, repairs outside the licensed system and no legible EPAL mark. The defects index covers each one. Sound pallets are usually worth more sold than recycled, so sort first if you can.
Tell the recycler about contamination
If pallets carried chemicals, oil or food that spoiled, say so in the notes. It changes how they can be handled and processed.
