What Happens to Old Pallets? The Full Lifecycle Explained

Every pallet starts as a tree and ends as something useful — whether that's another pallet, a garden bed, or energy for an industrial boiler. Here's the complete lifecycle of a wood pallet, from creation to final disposition.

Stage 1: Manufacturing

A new pallet begins at a sawmill, where logs are cut into boards and stringers. The cut lumber is assembled into pallets using pneumatic nail guns. A standard GMA pallet (48" x 40") uses approximately 12 board feet of lumber.

Most new pallets in the U.S. are made from hardwoods (oak, maple) or softwoods (pine, spruce). Hardwood pallets are heavier and more durable; softwood pallets are lighter and less expensive.

After assembly, export pallets undergo heat treatment to meet ISPM-15 standards.

Stage 2: First Use

The new pallet enters the supply chain carrying its first load — maybe a pallet of canned goods leaving a manufacturing plant for a distribution center. Depending on the supply chain model, this pallet might travel 50 miles or 5,000 miles on its first trip.

Stage 3: Reuse Cycles

After its first delivery, the pallet's journey depends on the supply chain model:

Open loop: The pallet stays with the receiver and gets used for their own shipping needs or accumulated for recycling pickup.

Closed loop: The pallet is returned to the original shipper or a pooling company for cleaning, inspection, and redeployment.

A well-maintained pallet can go through 15-20 reuse cycles before it needs repair, and many more after that with proper maintenance.

Stage 4: Repair and Refurbishment

When a pallet sustains damage — a cracked board, a popped nail, a split stringer — it enters the repair stream. At a pallet recycling facility like ours, skilled workers assess each pallet and perform targeted repairs:

A pallet can be repaired multiple times over its lifetime. Each repair extends the useful life of the original lumber by another full use cycle.

Stage 5: Dismantling

Eventually, a pallet reaches the point where repair isn't economical — too many broken boards, weakened stringers, or accumulated damage. At this stage, it's dismantled. Usable boards are pulled for use as repair stock in other pallets. Hardware (nails, screws) is recovered for recycling.

Stage 6: Grinding

Wood that can't be reused as boards goes to the grinder. Industrial wood grinders reduce pallet lumber to chips of various sizes, which find new life as:

Stage 7: Energy or Soil

At the very end of the chain, pallet wood either converts to energy (through biomass burning) or returns to the soil (through composting or natural decomposition of mulch). Either way, the carbon captured by the original tree during its growth is eventually released — but only after the wood has served productive purposes for years or even decades.

The Circular Reality

The pallet lifecycle is one of the most successful examples of circular economy in industrial materials. With recycling rates above 95% industry-wide, wood pallets demonstrate that reuse, repair, and material recovery can work at massive scale. The key is having a network of recyclers, like Stockton Pallet Co., that keep the cycle turning.
