The highlights of Vietnam wood pellet

Vietnam’s emergence as the second largest wood pellet producer globally, trailing only the United States, marks a significant development in the country’s renewable energy sector. The majority of Vietnam’s wood pellet production is destined for export, with over 95% of the volume shipped to South Korea and Japan, where it is used as an input material for power generation. This upward trend in exports underscores the increasing demand for renewable energy sources in Asia, particularly in South Korea and Japan, and Vietnam’s growing role in supplying this demand.

Wood pellet: Solutions for Green environment

Wood pellets are products made from natural wood materials, normally are sawdust, wood shavings, and other wood processing byproducts. These materials are compressed under high pressure to create compact, durable pellets that are convenient to use and store.

Composition

• Wood Material: Produced from wood by-products such as sawdust, wood shavings, wood chips, and other waste parts from wood processing.

Characteristics

• Moisture Content: Below 10%
• Ash Content: Usually below 1%
• Size and Shape: Industrial wood pellets are typically cylindrical, with a diameter ranging from 6 to 10 mm and a length of about 10 to 30 mm.
• Compression: Wood pellets need to have high compression to ensure optimal burning time and storage space.
• Calorific Value: Usually from 16.5 to 19 MJ/kg.

The Highlights of Vietnam wood pellet

Wood pellets are considered a clean and sustainable energy source, replacing traditional fuels. This renewable, environmentally friendly fuel has high combustion efficiency and is widely used in industrial boilers, biomass power plants, and household heating systems. As a result, wood pellets are increasingly popular, encouraged by scientist for several reasons:

• Renewable Resource: Wood pellets are manufactured from compressed sawdust and other wood waste generated by the lumber industry. Using these by-products reduces waste and makes better use of natural resources.
• Carbon Neutral: When burned, wood pellets emit the carbon dioxide that the trees absorbed throughout their growth, making them a carbon-neutral energy source. This contrasts with fossil fuels, which emit carbon that has been locked away for millions of years, contributing to atmospheric CO2 levels.
• Lower Emissions: Wood pellets burn cleaner than fossil fuels, emitting fewer pollutants like sulfur dioxide, nitrogen oxides, and particulates. This improves air quality and reduces the health risks linked with air pollution.
• Sustainable Forestry Practices: Wood pellets can be a component of sustainable forestry practices that guarantee ongoing tree planting and growth if they are supplied ethically. This contributes to the upkeep of healthy forests, which are essential for retaining biodiversity and absorbing carbon dioxide.
• Energy Efficiency: Wood pellets burn and travel more efficiently because of their low moisture content and high energy density. When weighed unit for unit, they yield more energy than raw biomass.
• Economic Benefits: By generating jobs in forestry, production, and transportation, the wood pellet business can boost rural economies. Additionally, it offers a market for waste products from other wood-working companies.
• Energy Security: By reducing reliance on imported fossil fuels, the use of domestically generated wood pellets improves a nation’s energy security and stability.
• Combating Climate Change: By replacing coal and other fossil fuels in power generation, wood pellets can significantly reduce greenhouse gas emissions, contributing to global efforts to mitigate climate change.

The manufacture process of wood pellet

The production process of wood pellets requires strict control at each stage to ensure the quality of the final product, optimize efficiency, and minimize production costs.

Collecting and Preparing Raw Materials

• Collection: The main raw materials for producing wood pellets include sawdust, wood shavings, and other wood waste from sawmills, wood workshops, or the wood processing industry.
• Sorting and Cleaning: The raw materials are sorted to remove impurities such as metals, stones, and non-wood materials.

Processing Raw Materials

• Grinding: The raw materials are ground into uniformly sized particles to facilitate more efficient compression.
• Drying: The moisture content of the raw materials must be reduced to about 10-15% to ensure high compression efficiency and good pellet quality. Drying can be done using equipment such as drum dryers or fluidized bed dryers.

Pelletizing

• Compression: The ground and dried materials are fed into a pellet mill. Under high pressure and temperature, the wood particles bond together without the need for additional binders. The pellet mill can be either ring die or flat die.
• Shaping: The compression process produces pellets of uniform size and shape, typically cylindrical with a diameter of 6-10 mm and a length of 10-30 mm.

Cooling and Surface Treatment

• Cooling: The pellets are hot after compression and need to be cooled to stabilize their structure and durability.
• Surface Treatment: The pellets are polished to remove sharp edges and smooth the surface, making them easier to transport and use.

Screening and Grading

• Screening: The pellets are screened to remove small particles, dust, and broken pellets. The small particles and dust can be reused in the production process.
• Grading: The pellets are graded by size and quality to ensure the uniformity of the final product.

Vietnam: The Second largest wood pellet exporter globally

In 2023, Vietnam’s wood pellet market exported a total of over 4.6 million tons, generating nearly 680 million USD in revenue. The two largest importers of Vietnamese wood pellets were Japan (2.8 million tons) and South Korea (1.47 million tons), accounting for 96% of the total volume and 96.6% of the country’s total export revenue. Despite making up a modest portion of global exports, the EU market expanded significantly in 2023, exporting over 155,000 tons and earning over 26 million USD. In comparison to 2022, this indicates an almost three-fold rise in volume and a 3.7-fold increase in value.

The statistics underscore the significant and continuous increase in both the volume and value of Vietnam’s wood pellet exports, driven by rising demand from major markets such as Japan and South Korea, as well as growing interest from the EU.

• 2022: Vietnam exported 4.9 million tons of wood pellets, generating a turnover of 0.79 billion USD.
• First Five Months of 2023: The export volume reached 1.57 million tons, with an export value of approximately 256.5 million USD.

In summary

For many aspects of life, industrial wood pellets offer an affordable, sustainable, and clean energy source. These items offer remarkable benefits and a wide range of uses, which not only contribute to environmental preservation but also yield substantial financial gains for their consumers. In addition, wood pellets offer a future-proof, cost-effective energy option in addition to helping to address the problem of wood waste.
