Sawdust Extruder in Cambodia Transforming Biomass into High Quality Charcoal

Meeting the Growing Demand for Sustainable Biomass Solutions in Cambodia

В последние годы, Cambodia’s agricultural and forestry sectors have witnessed a surge in byproduct generation—particularly sawdust from timber processing and agricultural waste from rural communities. As the global push for renewable energy intensifies, these residues are no longer seen as “waste” but as valuable raw materials for producing eco-friendly charcoal. В машине Weiwa, we’ve been at the forefront of this transition, providing tailored biomass solutions to Cambodian clients.

The Market Potential for Sawdust-Based Charcoal Solutions

Cambodia’s unique economic and environmental landscape makes it an ideal market for ​sawdust extruder machinesимашины для производства древесного угля. The country boasts vast forest resources, with timber processing being a significant industry—yet traditional charcoal production (often from native wood) contributes to deforestation and air pollution. Тем временем, sawmills generate substantial sawdust that is typically burned or discarded, creating both waste management challenges and missed economic opportunities.

Our on-site demonstration was conducted for a client in Kampong Cham Province, a hub for small-to-medium timber enterprises. The client, who previously relied on imported charcoal for local cooking fuel markets, sought a sustainable alternative that could convert their abundant sawdust into high-quality, densified charcoal briquettes. This case study not only highlights the ​sawdust extruder in Cambodia​ but also underscores the broader demand for efficient, low-cost ​sawdust extruder machines for sale​ that align with local operational conditions.

How Our Машина для изготовления древесного угля Works in Cambodia?

The heart of our solution lies in a two-stage process: ​sawdust densification via the extruderиcarbonization into charcoal. Let’s break down how each component performed during the on-site trial.

Этап 1: Sawdust Extrusion – Turning Loose Waste into Fuel-Ready Briquettes

Нашsawdust extruder machine​ is designed to compress loose sawdust into dense, цилиндрический “Брикеты” without the need for binders. During the demonstration, the client provided raw sawdust with a moisture content of approximately 12% (ideal for extrusion). The machine, powered by a diesel engine (adaptable to local electricity constraints), processed the sawdust at a rate of 80–100 kg/hour.

What set our extruder apart was its ​high-pressure screw mechanism, which generates sufficient frictional heat (up to 150°C) to soften the lignin in the sawdust naturally. Lignin, a natural polymer in wood, acts as an organic binder when activated, eliminating the need for chemical additives. The client observed how the extruder smoothly transformed fluffy sawdust into solid, однородные брикеты (diameter: 50 мм; length: 5–8 cm) with minimal clogging—a common issue with lower-quality machines.

“The extruder was surprisingly efficient,” noted the client’s operations manager. “We expected some downtime for adjustments, but it ran continuously for 4 hours without a single blockage, even with slight variations in sawdust particle size.”

Этап 2: Carbonization – Transforming Briquettes into Long-Lasting Charcoal

The extruded briquettes were then transferred to our ​Машина для изготовления древесного угля​ (a continuous carbonization furnace), where they underwent pyrolysis at temperatures of 450–600°C in a low-oxygen environment. Over a 6-hour cycle, the briquettes were converted into black, high-density charcoal with a fixed carbon content of 85%+ (tested on-site using a portable analyzer).

The client was particularly impressed by the ​low ash output (меньше, чем 3%)​​ and the charcoal’s ​burning time—up to 4 hours per briquette, compared to 2–3 hours for traditional wood charcoal. “This means our customers get more heat per unit, and we can sell it at a competitive price while maintaining healthy margins,” the client explained.

Key Metrics and Client Feedback

To quantify the success of the demonstration, we tracked three critical metrics: ​production efficiency, operational cost, and end-product quality.

• ​Production Efficiency: The combined system (extruder + карбонизация печи) processed 320 kg of raw sawdust into 280 kg of finished charcoal over an 8-hour day (accounting for minor losses during handling). This translates to a conversion rate of ~87.5%, exceeding the industry average of 80–85%.
• ​Operational Cost: The client’s total daily operating cost (including electricity/diesel for the extruder, furnace fuel, and labor) was approximately $45.Wiтhтhefinishedcharcoalsellinгfor$0.18–$0.22perkгinlocalmarkeтs,тhepoтenтialdailyrevenuefroм280kгis$50.40–$61.60—a net profit margin of 12–37%.
• ​End-Product Quality: Independent testing confirmed the charcoal’s high calorific value (5,800–6,200 kcal/kg), low smoke emission (meeting Cambodia’s environmental guidelines), and consistent size, making it ideal for household cooking and small-scale industrial use.

The client summarized their experience: “We’ve tested other machines before, but Weiwa’s combination of durability, ease of use, and output quality is unmatched. The extruder’s simple design means our workers can operate it with minimal training, and the charcoal’s performance gives us confidence to scale up.”
