The Dilemma of Plywood Mill Residues: Plywood Scrap, Waste and Offcuts Disposal
（Plywood scraps）
The stringent quality requirements for premium plywood—fine, uniform, straight-grain timber free of knots, bends, cracks, decay, or scars—inevitably lead to the rejection of defective logs and the generation of large volumes of scrap, offcuts, and mill residues at every stage of production. High-grade timber yields high-value plywood products — top European plywood can reach 500 EUR per cubic meter.
To solve solid waste problems and boost secondary revenue, recycling plywood mill residues for presswood pallet production has become a proven high-value business solution for plywood factories worldwide.

Traditional Plywood Waste Recycling: Value Released but Underexploited
Plywood residues are recycled into particleboard/MDF/fiberboard or processed into biomass fuel for industrial use.

Traditional recycling of plywood scrap offers low returns, while using it to produce ISPM 15-compliant presswood pallets creates far higher value—fumigation-free for simplified export, with superior eco-friendly and economic advantages over conventional pallets.
Why Factories Differ Greatly in Plywood Waste to Presswood Pallet Production
Many factories use identical plywood scrap raw materials but achieve completely different production results — some struggle with low efficiency and slim profits, while others secure stable long-term export orders.
The performance gap depends on three core factors: scientific raw material proportioning, advanced MDI gluing technology, and a fully automated production line.
1. Scientific Grading & Proportioning of Plywood Scrap
A common misconception in the industry is that all plywood waste can produce qualified presswood pallets. In fact, plywood waste to presswood pallet quality relies not on the scrap itself, but on precise particle matching and gluing craftsmanship.
Coarse particles build pallet skeletons; fine particles fill gaps to boost density and water resistance. Pure coarse reduces compactness; pure fine weakens toughness. Improper ratios cause cracking, poor load-bearing, and lower competitiveness.
ThoYu customizes particle grading ratios according to clients’ specific plywood scrap types and sizes, ensuring stable pallet performance and maximizing raw material utilization and profit margins.
2. Advanced MDI Gluing Technology for Superior Durability
Gluing technology is the core of high-quality presswood pallet manufacturing. ThoYu’s cooperative MDI adhesive solution, developed with Wanhua Chemical, adopts modified MDI (Methylene Diphenyl Diisocyanate) for plywood waste to presswood pallet production.
Under high temperature and high pressure, the adhesive reacts with moisture in wood fibers to form a stable polyurea cross-linked structure, delivering three key enhancements:
Surface Film Formation: MDI reacts rapidly with water to form a dense waterproof polyurea film on wood fiber surfaces, greatly improving water resistance.

Hydroxyl Crosslinking: Wood hydroxyl groups crosslink with MDI molecules to form high-toughness structural bonds, strengthening pallet impact resistance.
3D Skeleton Integration: Thermal pressing integrates wood fibers and polyurea networks into a gap-free compact structure, ensuring overall structural stability.
3. High-Stability Automated Production Line
Manufacturing qualified export presswood pallets is not simple compression molding. It requires precise, full-process industrial control. ThoYu’s professional plywood scrap recycling line for presswood pallets features full PLC automatic control from glue mixing and hot pressing to pallet stacking, achieving a stable output of 13 pieces per hour with consistent product quality.
Front-end Raw Material Processing: The integrated production line includes crushing, metal removal, and fine pulverization, processing plywood offcuts into uniform 2mm fine particles with zero impurities, fully meeting subsequent drying, gluing, and pressing standards.

ISPM 15 Compliance: Fumigation-Free Advantage for Global Export
During high-temperature (180℃) and high-pressure molding, all pest eggs and bacteria in recycled plywood scrap for pressed wood pallets are completely eliminated. Finished products fully comply with ISPM 15 international phytosanitary standards, requiring no fumigation treatment for global export. This saves quarantine costs, shortens delivery cycles, and greatly simplifies cross-border logistics procedures.
Our presswood pallets made from plywood offcuts processing machine for pressed pallet feature outstanding comprehensive performance:
Strong Load Capacity: Dynamic load up to 1.5 tons, static load up to 6 tons, stable performance after water soaking and drop tests.
Wide Environmental Adaptability: Mildew-proof and moisture-resistant, suitable for high-humidity warehouses, cold storage, and other harsh scenario
Space-Saving Design: 20 stacked pallets only occupy 0.75 meters in height, saving 70% of warehouse and shipping space to reduce logistics costs.
Customization Support: Multiple mature styles and customized shelf pallets are available, serving global clients and meeting diverse supply chain needs.
