1. The working principle of wet wood pallets biomass pellet processing equipment

The overall principle of wood pallet pellet processing equipment is essentially to transform "irregular, high-impurity, high-moisture" waste wood pallets into "regular, impurity-free, high-density, and easy-to-store" biomass pellets through the continuous physical processing of "dismantling and impurity removal → crushing and volume reduction → crushing and refinement → drying and moisture control → high-temperature and high-pressure molding → cooling and stabilization." No chemical agents are added throughout the process, and molding is achieved by relying on the adhesiveness of the wood's own fibers. This not only solves the problem of environmentally friendly disposal of wood pallet waste, but also achieves resource recycling (the pellets can be used as fuel, feed carrier, etc.).

2. Characteristics of wet wood pallets biomass pellet processing equipment

(1) High-strength crushing/smashing system to cope with "large block + hard" raw materials

Wood pallets are mostly whole boards (usually 1.2m×1.0m, 1.1m×1.1m in size), and some are plywood and solid wood hard materials. The crusher needs to have high torque and wear resistance

(2) High-efficiency impurity removal device to accurately separate "metal + non-metal" impurities

The key pain point of wood pallet processing is "containing metal nails and plastic accessories". The equipment usually integrates a multi-stage impurity removal system to ensure the purity of the particles

(3) Wide range of moisture content adaptation to reduce drying energy consumption

Wood pallets have different storage environments and large differences in moisture content (15%-30%). The drying system of the equipment (mostly a drum hot air dryer) can achieve precise temperature control (80-120℃) and humidity adjustment, stabilizing the moisture content of wood chips at 10%-15% (the optimal humidity for pelletizing)

(4)Wood pallet pellet processing requires multiple steps: crushing → impurity removal → pulverization → drying → pelletizing → cooling → screening. Equipment typically comes in the form of a complete production line, with core features including a consistent process flow and a high degree of automation.

(5)Wood pallet raw materials (especially plywood and hardwood) subject equipment components to significant wear and tear, making durability a key feature.

(6)Wood pallet processing is prone to dust and noise, and poses significant risks to mechanical safety. Therefore, the equipment features specific environmental and safety design features.

(7)Wood pallet pellet production equipment can be flexibly adjusted based on the user's production capacity, site, and intended use of the finished product, meeting diverse needs.

3. Application scenarios of wet wood pallets biomass pellet processing equipment

(1) Civilian solid fuel: Wet pallet pellet fuel has a high utilization rate, is easy to store and use, is hygienic and safe, and can be used for home heating.

(2) Main solid fuel for industrial boilers: It can replace raw coal, heavy oil, and gas, reducing air pollution. Every 10,000 tons of biomass fuel burned can replace 7,000 tons of standard coal, reducing sulfur dioxide emissions by 165 tons, smoke emissions by 80 tons, and carbon dioxide emissions by 14,400 tons.

(3) Thermal power generation: The fuel calorific value can reach 3,400-6,000 kcal.

In short, wet wood pallet biomass pellet fuel can be described as "environmentally friendly", "energy-saving", "renewable", and "zero-carbon emission", and is the best renewable energy source to replace coal. From the perspectives of cost, energy saving, and environmental protection, biomass fuel is a better alternative to coal.

TONY Brand32-40 Ton/Hour Wet Wood Pallets Pellet Manufacturing Plant can take wet wood pallets, various types of wood - related biomass materials, such as branches, small - diameter logs, and wood shavings, with wet wood as the main raw material. After pretreatment and processing, it is solidified into high - density wood pellet fuel. This fuel is an ideal substitute for coal and oil and plays a role in energy conservation and emission reduction. At present, it has been widely used in regions rich in wood resources.

Three Fundamental Supports for the Feasibility of Processing Wooden Pallets into Biomass Pellets

The success of this project hinges critically on the maturity of three key factors: raw material supply, policy guidance, and market demand. These factors are also the core focus of preliminary research.

1. Raw Material Supply: Stable and low-cost raw material supply is a prerequisite.

The source, supply volume, and cost of discarded wooden pallets directly determine project profitability and require critical assessment:

Raw Material Source Scenario:

Core Channels: E-commerce logistics warehouses, manufacturing factories (auto parts, home appliances, machinery), ports/bonded areas (discarded IPPC pallets from cross-border trade), and pallet rental companies (damaged and retired pallets).

Supply Characteristics: Discarded pallets in these scenarios are typically generated in bulk and are often recycled for free or at a low price, resulting in extremely low raw material costs.

Suitability of Raw Material Processing:

Wooden pallets (especially solid wood pallets) have a high wood fiber density, resulting in pellets with a calorific value of 4200-4800 kcal/kg (similar to medium-quality coal), surpassing agricultural waste such as straw and rice husks. Removal of metal (nails, clips) and minimal oil contamination is required, eliminating the need for complex pre-treatment and making them highly suitable for processing. 

2. Policy Direction: Dual Benefits of Environmental and Energy Policies

Biomass pellets, as a compliant alternative fuel, have low market entry barriers. This project falls under the "solid waste resource utilization" category, meeting the "reduction and resource utilization" requirements.

3. Market Demand: Strong demand in both industrial and residential applications

The market demand for biomass pellet fuel has stabilized, eliminating the need to worry about "selling out":

Industrial (Core Customers): Small and medium-sized boilers (1-10 tons) in food processing, textile, and building materials factories, ceramic kilns, and biomass power plants (for co-firing).

Residential (Supplementary Customers): Home heating stoves, cooking energy in southern farmhouses and small restaurants, and home fireplace users.

1. Resource Recycling: Solving the "Solid Waste Problem"

Waste-to-Resource: Used wooden pallets are a common source of solid waste in the logistics and warehousing industries. If they are discarded or incinerated without proper treatment, they can lead to resource waste and environmental pollution. Pallet pellets transform them into high-value products.

2. Excellent performance: Suitable for multiple scenarios and easy to use.

As biomass pellet fuel or industrial auxiliary materials, pallet pellets offer stable physical and chemical properties, providing a superior user experience compared to traditional bulk wood, coal, and other materials.

3. Outstanding environmental performance: Low pollution.

The clean nature of pallet pellets is a core competitive advantage.

4. Significant economic value: Low cost and stable returns.

From production to application, the economic advantages of pallet pellets permeate the entire supply chain. Demand for biomass pellets is strong, and revenue is stable.

The core advantages of pallet pellets are their triple combination of environmental protection, cost-effectiveness, and practicality. They solve the solid waste disposal problem of used pallets and provide a clean and efficient alternative energy source. They balance low production costs with convenient application. Therefore, they have broad application prospects in logistics waste recycling, biomass energy, and clean heating. They are also a "circular economy + green energy" project encouraged by current policies.
