Renewable Biomass Pellet Plant in Vietnam

RICHI MACHINERY

overview

RICHI Machinery, as a professional manufacturer of feed equipment, biomass pellet equipment, organic fertilizer systems, and cat litter production lines, was commissioned to supply and engineer a 5t/h renewable biomass pellet plant in Vietnam for a local clean energy investor.

This renewable biomass pellet plant in Vietnam is designed with a production capacity of 5 tons per hour, operating 8 hours per day, 300 days per year, achieving an annual output of 12,000 tons of biomass pellets. The project is located in northern Vietnam, within an established industrial land area of 2,544 m², with a total building area of approximately 4,500 m².

The client utilized an existing factory building and carried out internal renovation and equipment installation without constructing new buildings. This significantly reduced investment risk and shortened project implementation time.

The total project investment is approximately USD 285,000, of which the core production line equipment supplied by RICHI Machinery accounts for approximately USD 165,000, including pelletizing system, crushing system, dust collection system, conveying system, and auxiliary equipment.

This renewable biomass pellet plant in Vietnam processes agricultural and forestry residues into high-density solid biofuel pellets for industrial boilers and commercial heating markets.

Project Background and Client Profile

The client is a privately owned renewable energy investor engaged in agricultural resource recycling and biomass fuel trading in Vietnam. Northern Vietnam has abundant agricultural by-products such as rice straw, corn stalks, tobacco stems, and wood residues from furniture factories. However, large volumes of these residues were previously burned in open fields or left unused.

With Vietnam’s growing demand for industrial heating fuel and export-oriented biomass markets, the client decided to invest in a renewable biomass pellet plant in Vietnam to convert low-value agricultural waste into standardized 8mm diameter fuel pellets.

The biomass pellet project is strategically located near major agricultural villages and woodworking workshops, ensuring stable raw material supply. The pellets are mainly supplied to:

Industrial steam boiler users
Textile and food processing factories
Local brick kilns
Commercial heating applications
Export traders

The biomass pellet production line operates as a renewable energy conversion facility that supports Vietnam’s clean energy transition and rural income enhancement.

Raw Materials

Vietnam is one of Southeast Asia’s largest rice producers, with significant agricultural residues generated annually. In addition, furniture manufacturing clusters generate large volumes of wood offcuts and sawdust.

For this renewable biomass pellet plant in Vietnam, the raw materials are locally sourced and carefully controlled in moisture content to reduce drying requirements.

Raw Materials and Consumption

No.	Raw Material	Annual Quantity (t)	Average Moisture	Source
1	Wood offcuts, sawdust	6,150.9	15–20%	Furniture factories
2	Straw, tobacco stems	14,352.1	18–25%	Local villages
3	Electricity	13,000 kWh	—	National grid
4	Water	240 t	—	On-site well
5	Packaging bags	0.7 t	—	Purchased

The biomass pellet manufacturing plant does not add any adhesives or chemical binders. Pellet formation relies purely on mechanical compression and lignin binding.

Moisture of incoming materials is controlled below 30%. If moisture exceeds 20%, materials are pre-dried naturally before processing.

Production Process Description

The renewable biomass pellet plant in Vietnam adopts a physical compression pelletizing process without thermal drying or chemical additives.

Process Flow

Raw Material Collection → Natural Drying (if needed) → Crushing → Grinding → Cyclone Separation → Bag Filter Collection → Pelletizing → Cooling → Screening → Packaging

Detailed Process Explanation

1. Raw Material Collection and Moisture Control

Agricultural residues are collected through designated village collection points. Moisture is monitored before processing. Materials above 20% moisture are naturally dried.

2. Crushing

Large wood pieces and stalk bundles are processed by the crusher into smaller chips. Dust generated is collected by a bag filter system.

3. Grinding

The hammer mill reduces particle size to below 5 mm. Dust passes through a cyclone and bag filter system and is recycled back to production.

4. Pelletizing

Two 2.5 t/h ring die biomass pellet mills compress the biomass into 8mm pellets. The process is purely mechanical, relying on natural lignin binding.

5. Cooling and Conveying

Fresh pellets are conveyed via bucket elevators and screw conveyors. Natural cooling reduces pellet temperature before storage.

6. Screening and Packaging

Qualified pellets fall into the finished product bin. Unqualified materials are recycled back to pelletizing. Final products are packed in 15–25 kg bags.
