"Recycled Wood" specifically refers to the use of discarded wooden materials that have been previously used or processed, eliminating the need to harvest from natural or planted forests.
Its primary sources include:
1. Demolition & Construction Waste: Wood reclaimed from old buildings and structures, such as beams, columns, and planks.
2. Industrial & Commercial Waste: Used logistics pallets, packaging crates, and construction formwork.
3. Wood Processing Residues: Off-cuts, shavings, and sawdust from furniture and sawmills (typically larger off-cuts are relevant for this line).
4. Urban Wood Waste: Tree trimmings, discarded wooden furniture, etc.
Key Characteristics: Complex sources, irregular shapes, and high impurity content (e.g., metals, paint, sand, plastic). Therefore, a production line using recycled wood must be equipped with a powerful pre-treatment and purification system.
The core of this production process lies in the complex front-end raw material treatment stages, which are essential for ensuring final product quality.
1. Raw Material Reception & Primary Size Reduction:
Recycled wood is delivered to the plant for initial inspection and sorting.
A heavy-duty shredder breaks down large, irregular wood waste into smaller, manageable pieces.
2. Deep Purification & Sorting:
Magnetic Separation: Uses powerful magnets to remove ferrous metals like nails and screws.
Air Separation / Aspiration: Utilizes air flow to separate light impurities such as plastic, paper, and dust.
Washing / Mechanical Cleaning (Critical Step): Removes sand, stones, and adhesions through friction and rinsing.
Intelligent Sorting (Optional): Employs near-infrared or AI vision technology to separate non-wood materials.
3. Stranding / Flaking:
The purified wood pieces are fed into a flaker to produce wood strands that meet OSB specifications.
4. Drying & Screening:
Wet strands enter a dryer to reduce moisture content to the required level.
Dried strands are screened to remove oversized and fine particles, retaining the合格 strands.
5. Blending & Resin Application:
Qualified strands are uniformly mixed with MDI Resin, wax, and other additives in a large blender. MDI resin is the preferred choice for recycled wood OSB due to its superior bonding strength and formaldehyde-free nature.
6. Oriented Forming:
The resinated strands are spread by an advanced forming machine onto a moving belt to create a multi-layered mat. The surface strands are oriented parallel to the production direction, while the core strands are oriented crosswise, giving the board high strength and dimensional stability.
7. Hot Pressing:
The mat enters a continuous hot press. Under high temperature and pressure, the MDI resin cures rapidly, bonding the recycled wood strands firmly into high-strength OSB panels.
8. Cooling, Trimming & Packaging:
The pressed panels are evenly cooled on a cooling conveyor.
They are cut to standard sizes by cross-cut and trim saws, then stacked, bundled, and sent to storage.
1. Raw Material Pre-treatment Section:
Heavy-Duty Shredder: For initial size reduction of large recycled wood.
Magnetic Separator: Removes ferrous metals.
Air Separator / Aspirator: Separates light impurities.
Washing System: Cleans strands, removing sand and dirt.
Intelligent Sorter (High-end configuration): Uses optical or AI technology to enhance sorting precision.
2. Strand Preparation & Treatment Section:
Flaker / Strander: Produces specification strands.
Rotary Drum Dryer: Dries the strands.
Strand Screening System: Classifies dried strands.

3. Forming & Pressing Section:
Measuring Bins & Blender: Precisely meters and mixes strands with resin.
Oriented Forming Machine: A core component, creates the oriented mat structure.
Continuous Hot Press: The most critical equipment, enables continuous high-pressure panel forming.

4. Finishing & Support Systems:
Cooling Star / Turnover Cooler: Cools the panels.
Cross-Cut & Trim Saws: Cuts panels to length and width.
Sanding Machine (Optional): Provides surface finishing.
Central Control System: Automates and controls the entire production line.
Dust Extraction & Environmental Protection System: Handles dust and exhaust gases generated during production.

1. Ultimate Environmental Sustainability, Creating Green Value:
Zero Forest Footprint: Consumes no forest resources. Every cubic meter of OSB produced saves several cubic meters of timber.
Waste Reduction: Effectively addresses the disposal problem of urban and industrial wood waste, turning trash into treasure.
Low Carbon Footprint: The entire production process has a significantly reduced carbon footprint compared to conventional OSB manufacturing.
2. Exceptional Product Performance Without Compromise:
Through advanced process control, the OSB produced maintains high strength, stiffness, and excellent nail-holding capacity.
Capable of producing No-Added-Formaldehyde (NAF) boards compliant with international standards (e.g., Euro E1, CARB NAF), meeting requirements for green building certifications (e.g., LEED, BREEAM).
3. Significant Economic Benefits:
Extremely low raw material costs, primarily sourced from waste procurement, offering a clear cost advantage.
The "green" attribute of the finished OSB often commands a market premium, leading to higher profit margins.
4. Intelligence & High Efficiency:
The line is highly automated, featuring intelligent detection and sorting systems to ensure stable and efficient operation.
Integrated energy recovery systems minimize overall energy consumption.
1. Source Environmentalism: Resource Circulation & Waste Reduction
Substitution for Virgin Forest Resources: By using 100% recycled wood as raw material, the production line completely replaces the conventional model that requires tree felling. This directly protects forest resources and ecosystems, preserving biodiversity.
Reduction of Urban & Industrial Waste: It "rescues" construction waste, used pallets, and wood waste from landfills or incinerators, achieving resource recovery and high-value utilization of waste. This effectively addresses the challenge of waste management and aligns with the core principles of the circular economy.
2. Process Environmentalism: Energy Saving & Clean Production
Energy Recovery and Reuse: The line is designed with integrated energy recovery systems. For instance, waste heat from the hot press is captured and used for drying strands, significantly reducing external energy consumption (e.g., natural gas, coal) and the associated carbon emissions.
Low-Energy Consumption Equipment: Employs high-efficiency motors, variable frequency drives, and intelligent control systems to optimize energy use and avoid waste.
Dust & Emission Control: Equipped with high-efficiency baghouse dust collectors and central dust extraction systems that capture wood dust and particles generated during production. This collected material can often be used as fuel, preventing uncontrolled emissions. Furthermore, the use of environmentally friendly MDI resin ensures no emission of formaldehyde, phenol, or other harmful VOCs during production or from the final product, guaranteeing a safe workplace and clean exhaust emissions.
3. Product Environmentalism: Safety & Green Certification
Health and Safety: The use of MDI eco-friendly adhesive enables the production of OSB panels that are "No-Added-Formaldehyde" (NAF). Their formaldehyde emissions are extremely low, typically meeting the world's most stringent standards like CARB NAF or China's ENF level. This makes the panels safe for human health, ideal for spaces with high indoor air quality requirements, such as schools, hospitals, and residences.
Contribution to Green Building: This product is a significant contributor to achieving international green building certifications like LEED, BREEAM, and DGNB. Construction projects using these panels gain credits in categories such as "Materials & Resources" and "Indoor Environmental Quality," facilitating higher ratings.
4. Systemic Environmentalism: Minimizing Overall Life-Cycle Impact
Water Circulation: Wastewater generated from washing strands can be treated and recycled, reducing freshwater consumption and sewage discharge.
Closed-Loop Design: Process waste generated by the line itself (e.g., screened-out fines, trim ends) can be collected and used as fuel or recycled back as raw material, creating an internal "small loop" within the production system.
This production line is ideal for investors worldwide in the green building, sustainable furniture manufacturing, and eco-friendly packaging sectors. We provide comprehensive "turnkey" services, from planning and design, equipment integration, to installation and training, making it your premier partner for entering the circular economy and building a green brand.
