Coffee wood materials used for producing Coffee Binchotan white charcoal in Vietnam are mainly collected from coffee plantation replanting activities, annual pruning and plantation renovation, replacement of old or low-yield trees, or conversion to other agricultural and fruit crops with higher economic value.
Vietnam is one of the world’s leading coffee-producing countries, especially well known for Robusta coffee production. According to recent USDA reports, Vietnam’s coffee production for the 2025/26 crop year is estimated at approximately 31 million bags, reflecting the enormous scale of the coffee industry as well as the significant volume of wood biomass generated annually from plantation renovation and replanting activities.
Vietnam’s coffee-growing regions are mainly concentrated in the Central Highlands including Dak Lak, Lam Dong, Gia Lai, Dak Nong, Kon Tum, and parts of Southeast Vietnam. These regions possess favorable climate conditions, rainfall, altitude, and soil characteristics suitable for coffee cultivation. Recent statistics indicate that Vietnam currently maintains more than 700,000 hectares of coffee plantations, with Robusta accounting for the majority.
After many years of cultivation, old coffee plantations gradually experience declining productivity, unstable fruit quality, and increasing maintenance costs. Many agricultural development programs recommend replanting coffee trees after approximately 20–25 years of production in order to maintain economic efficiency. As a result, the removal of old trees, replacement with new varieties, or crop conversion activities regularly take place across major coffee-growing regions.
Unlike forestry timber species used for furniture or industrial wood processing, coffee tree trunks are generally small in diameter, heavily branched, irregular in shape, and contain many knots, making them unsuitable for deep wood processing industries. Therefore, most coffee wood generated from plantation renovation is utilized as biomass fuel or raw material for charcoal carbonization, helping increase the value of agricultural by-products while reducing biomass waste.
For Coffee Binchotan white charcoal production, coffee wood materials are generally selected more carefully to ensure suitable hardness, dryness, and structural characteristics for carbonization and deep heat-treatment processes. After the initial carbonization stage, the charcoal is further refined at high temperatures of approximately 800–900°C based on Japanese Binchotan production techniques to remove most remaining volatile compounds inside the charcoal structure. This process creates a cleaner-burning charcoal product with improved heat stability, lower smoke emission, and significantly higher carbon content compared with conventional coffee wood charcoal.

Overview
White Charcoal (Binchotan) is a premium charcoal product originating from Japan and developed from the traditional charcoal-making techniques practiced by craftsmen in the Kishu region (present-day Wakayama Prefecture) during the Edo Period (1603–1868).
Unlike conventional charcoal, which only undergoes carbonization at approximately 350–400°C, Binchotan is further refined at extremely high temperatures ranging from 900–1000°C. This additional refining stage removes almost all remaining moisture, wood tar, natural oils, and volatile compounds from the charcoal structure while significantly increasing carbon content, density, hardness, and combustion performance.
In Vietnam, this technique has been adapted to produce White Charcoal from various suitable wood species, including Lychee Wood, Eucalyptus Wood, Coffee Wood, Longan Wood, Mai Tiew Wood, and other dense hardwood materials. The finished product is characterized by its dense structure, metallic ringing sound when two charcoal sticks are tapped together, high heat output, smokeless and odorless performance, low ash content (typically 1–2%), and extended burning duration of up to 4.5 hours.
The production of White Charcoal requires a high level of craftsmanship, strict temperature control, and extensive practical experience throughout the manufacturing process.

Step 1. Raw Material Sourcing
Raw materials are selected from wood species suitable for White Charcoal production, including Lychee Wood, Eucalyptus Wood, Coffee Wood, Longan Wood, Mai Tiew Wood, and other dense hardwood species.
Depending on the product category, the wood may originate from fruit orchards, plantation forests, or other appropriately managed raw material regions.

Step 2. Wood Preparation
The wood is cut into billets of suitable length and diameter according to kiln specifications.
Logs affected by decay, severe cracking, insect damage, or hollow cores are removed to ensure consistent product quality.
For White Charcoal production, freshly harvested and dense wood is generally preferred because it produces harder and more uniform charcoal after the refining process.

Step 3. Kiln Loading
The prepared wood is manually loaded into the kiln according to the kiln design and the experience of the charcoal craftsmen.
Proper stacking helps maintain efficient heat and gas circulation throughout the production cycle.

Step 4. Preheating & Moisture Removal
The kiln is gradually heated to increase the internal temperature in a controlled manner.
During this stage, most free water and moisture contained within the wood are slowly removed. Escaping water vapor typically creates the characteristic white smoke observed during the early stages of production.
This stage may continue for several days depending on the wood species and kiln capacity.

Step 5. Carbonization
The temperature is gradually increased to approximately 350–400°C under oxygen-limited conditions.
Natural oils, wood tar, minerals, and volatile organic compounds are progressively removed from the wood structure. During this stage, the wood gradually changes from its natural color to the characteristic black appearance of charcoal.
This process forms the basic charcoal structure before the final refining stage.

Step 6. High-Temperature Refining
This is the most important stage of the entire White Charcoal production process.
After carbonization is completed, the kiln openings are adjusted to increase airflow and oxygen supply to the combustion chamber. The kiln temperature is then rapidly increased to approximately 900–1000°C over a period of 24–36 hours.
At these extremely high temperatures, nearly all remaining moisture, wood tar, natural oils, and volatile compounds are removed. The carbon structure is further refined, resulting in exceptionally hard charcoal with high heat output, virtually no smoke, and almost no odor.
The timing of this stage is determined largely by the experience of the craftsmen. If the process is stopped too early, the charcoal may not reach its full quality potential. If continued for too long, excessive burn-off may reduce both yield and product quality.
The average white charcoal recovery rate ranges from approximately 8-14%, meaning that every 100 kg of raw wood typically yields around 8-14 kg of finished charcoal.

Step 7. Rapid Cooling
After the refining stage is completed, the glowing hot charcoal is carefully removed from the kiln while still at extremely high temperatures.
This operation requires considerable skill and experience, as dropping the charcoal or exposing it too abruptly to temperature changes may cause cracking or breakage.
The charcoal is immediately transferred into sealed drums, pits, tanks, or other enclosed cooling systems. Dry sand is then added to completely cover the charcoal, and the containers are tightly sealed with clay or mud mortar to isolate the charcoal from oxygen. This process extinguishes combustion and rapidly reduces the temperature while preserving the charcoal structure and appearance.
The cooling process typically takes around 12 hours before the charcoal can be handled safely.

Step 8. Cleaning & Finishing
The charcoal is cleaned to remove loose ash and surface dust. Fragile end sections may be trimmed before grading and packaging.
This stage improves product appearance and facilitates subsequent handling and packaging operations.

Step 9. Sorting & Quality Inspection
The charcoal is graded according to size, weight, color, hardness, and overall appearance.
For many Binchotan products, the metallic ringing sound produced when two charcoal sticks are tapped together is also considered one of the indicators of quality and carbonization performance.

Step 10. Packaging
Products are packed according to market requirements and customer specifications.
White Charcoal is commonly packed in cartons, PP bags, or OEM / Private Label packaging formats.

Step 11. Warehouse Storage & Final Inspection
Finished products are stored in dry and well-ventilated warehouse conditions for a minimum of 7 days before shipment.
A final quality inspection is conducted to verify product quality and packaging specifications according to the order requirements.

Step 12. Container Loading & Export
After final approval, the products are loaded into containers and transported to the port for export according to the agreed international trade terms.
Container loading capacity may vary significantly depending on the charcoal type, dimensions, and packaging format.
