Where is Wood Waste from?

Forest Planting

Wood Waste from Forest Plant

Wood Waste from Forest Planting

In forest planting, wood waste mainly consists of trunks and branches from trees. They are usually produced during the daily maintenance of forests.

Forest Harvest

Wood Waste from Forest Harvest

Logging and timber harvesting operations produce these wastes, which include materials unfit for commercial use. They include small trees, tree tops, and un-merchantable wood left in the forest after harvesting.


Waste Wood from Sawmill

These wastes are generated during the processing of sawn timber in sawmills. They’re by-products and residues from the sawing process, including wood scraps, including logs, wood chips, bark, sawdust, and shavings.

Wood Processing Factory

Waste Wood from Wood Processing Factory

Wood processing waste refers to materials generated during the production of wood products. They encompass a range of by-products from all aspects of the wood industry.

Wood Board Processing: This kind of wood waste involves the waste generated during the cutting, shaping, and finishing of wood board manufacturing.

Furniture Production: It includes the offcuts generated during the furniture manufacturing process. In addition, it also includes wooden parts of used furniture.


Wood Waste from Gardening

Garden waste is a biological type of waste. They are collected during municipal garden maintenance activities. It typically consists of branches, sticks, trimmings, and various multiple woody organic wastes.

Limitation of Existing Treatment of Wood Waste

Accumulation & Landfilling

Accumulation & Landfilling:

Greenhouse Gas Emissions: Greenhouse gases such as methane can be released during the accumulation and decomposition of wood waste.

Limited Space: Landfill space is limited, and excessive accumulation of wood waste can lead to the depletion of available landfill space.

Fire Risk: Wood waste that is stockpiled or landfilled is often left unattended. As a flammable material, it may pose a fire hazard.

Burn Directly

Burn Directly

Air Pollution: Burning releases particulate matter and harmful gases, such as sulfur dioxide, nitrogen oxides, and volatile organic compounds.

Incomplete Combustion: Moisture and volatile matter are present in wood. Even as a fuel, burning wood directly does not fully unleash the combustion performance of the wood.

CO/CO2 Emissions: Although wood is considered a renewable resource, burning it releases CO/CO2, resulting in greenhouse gas emissions.



Slow Decomposition: Wood materials decompose slowly compared to other organic waste. This results in large amounts of waste wood facing short-term disposal challenges.

Greenhouse Gas Emissions: During the composting process breakdown of wood waste may lead to the release of methane, a potent greenhouse gas.

How to Make Charcoal From Wood Waste?

Wood to charcoal machine uses wood resources as raw materials. After pyrolysis, the carbon and hydrogen elements in the raw materials are converted into mixed combustible gases with high calorific value. It also produces charcoal and by-products, including wood vinegar and tar. The following is the specific wood charcoal making process for your reference.

Wood Pretreatment
Through dryer and crusher, the size of the wood is less than 20mm (5-8mm is optimal), and the moisture content is less than 15%.
Wood Feeding
Pre-treated wood is transported to the pyrolysis reactor by a large inclination belt conveyor.
Main Furnace Preheating
Start the burner to heat the main furnace for 60-90 minutes. Different fuels match different burners.
Wood Pyrolysis

This process takes place in the wood carbonization furnace. The reaction temperature is 380℃to 450℃ in a hypoxic and micro-pressure environment.

  • Step 1- Dehydrate: Remove internal water;
  • Step 2- Demethylation: Remove hydrogen, methane, ethane, carbon monoxide and other mixed biogas;
  • Step 3- Volatile release: Remove tar, methanol, ethylene, and other substances.
Combustible Gas Recovery
The combustible gas is subject to dust removal and condensation treatment. The combustible gas obtained after treatment enters the combustion system for reuse. It provides a heat source for equipment operation.
Wood Charcoal Collection
High-temperature charcoal from the reactor enters the discharging system. The heat of the charcoal is taken away by the cooling water flowing in the slag discharge spiral. Its temperature will be reduced to below 45℃. Finally, the finished charcoal will be collected for storage or awaiting further processing.

Application of Wood Charcoal

Wood from forests and wood processing can be recycled by wood biomass pyrolysis plant. Meanwhile, charcoal comes back to serve these sectors in a sustainable cycle. What’s more, because of application versatility, charcoal finds widespread use across various industries.

Circular Application of Wood Charcoal

Soil Remediation or Improvement in Foresty Industry

Wood charcoal produced by pyrolysis is a kind of biochar. So it can be returned to the forest industry for soil remediation or improvement purposes. Wood charcoal’s porous structure helps the soil retain water and aeration. Its alkaline nature helps reduce soil acidity. This improved soil structure helps forest plant roots grow deeper into the soil. Consequently, forest plants have increased access to nutrition and improved resistance to fire, drought, wind, and cold.

Providing Fuel for Wood Processing Industry

Freshly cut wood contains a lot of water. To ensure the quality of wood products, drying the wood is essential. The sawdust charcoal making machine can convert wood processing waste into charcoal. It can serve as a fuel to dry the logs. This self-sufficient fuel supply reduces the use of traditional fossil energy. Through the recycling and reuse of waste wood, the wood processing industry realizes a closed loop of the circular value chain.

Suggestions for Choosing Wood Species to Make Charcoal

In theory, almost any type of wood can be processed by wood charcoal manufacturing machine. However, since common applications have specific requirements for combustion performance, wood selection becomes critical. Generally, hardwood and softwood are common classifications, and here are some of the wood species commonly used in charcoal production.

Hardwood Suitable for Making Charcoal

This kind od wood usually comes from deciduous trees that shed their broad leaves in winter, such as oak and maple. In terms of burning efficiency, due to higher density, hardwood generally has a longer burning time and can release more heat. Moreover, it produces less smoke during combustion. Therefore, hardwood is well-suited for charcoal production.

Beech: Its high carbon content and uniform texture contribute to the production of high-quality wood charcoal.

Oak: Oak’s wood fiber structure is robust and capable of yielding sturdy and durable charcoal. Oak charcoal exhibits excellent burning performance, producing a stable and long-lasting flame.

Eucalyptus: It has a short growth cycle, high wood density, and no distinctive odor. Additionally, eucalyptus charcoal has low ash content, with a carbon content that can reach up to 90%. These characteristics make it an excellent raw material for making wood charcoal.

Cherry wood, hickory wood, and walnut: They possess the advantages of hardwood mentioned above. Moreover, their slightly fruity flavor makes them ideal for grilling and smoking foods.

Softwood Suitable for Making Charcoal

Softwood usually comes from evergreen trees which have needle-like leaves, like pine and spruce. Such kind of wood often contains more resin. Therefore, this means that it tends to produce more smoke and less pleasant odors when burned. However, softwood is usually cheaper than hardwood, thus some people choose it for wood pyrolysis.
