Performance of pallet parts recovered from used wood pallets

The flexural modulus of elasticity (MOE), flexural modulus of rupture (MOR), and density of used pallet parts were measured and compared to the same properties of new parts. Seventy-four percent ofused pallet parts sampled were hardwoods, and 26 percent were softwoods. The average mixed hardwood par...

Description
Summary:The flexural modulus of elasticity (MOE), flexural modulus of rupture (MOR), and density of used pallet parts were measured and compared to the same properties of new parts. Seventy-four percent ofused pallet parts sampled were hardwoods, and 26 percent were softwoods. The average mixed hardwood parts were 41 percent stronger and 40 percent stiffer than the mixed softwood parts. The mixed eastern oaks were the most common species sampled, and reflected the relative volume of these species used to make new pallets. The average dry used oak deckboards were 47 percent stronger and 23 percent stiffer than green new oak parts, due primarily to the difference in moisture Content (MC). However, when adjusted to the same MC, the predicted average MOR deckboards. Without sortation, used parts dimensions were more variable than that of for use in future versions ofthe Pallet Design System program dealing with repaired and rebuilt pallets.
