1. What are rice husk pellets?

Rice husk pellets (husk pellets, rice husk pellets, rice husk pellets) are a type of biomass fuel composed of 100% rice husk - an agricultural by-product created during the rice production process.

The production process of rice husk pellets involves four main stages: grinding, crushing - pelletizing - dust screening, cooling - packaging. After sieving to remove impurities, the rice husk is sent to a grinding and crushing tank to be pulverized into husk powder. The husk powder is then fed into a high-pressure pelletizing machine through mold holes to form cylindrical pellets. Before packaging, the pellets pass through a dust filtering and cooling system to ensure the final product meets quality standards, with the required durability and hardness.

Technical specifications of rice husk pellets:

• Shape: Cylindrical, diameter 8-12mm, length 10-50mm
• Calorific value (DB): 3,800 – 3,900 cal/g
• Moisture content: < 15%
• Sulfur content: 0.07%
• Ash content: < 20%
• Fixed carbon content: 15.6%
• Volatile matter: 69.7%

2. Why use rice husk pellets?

- High efficiency: Rice husk pellets have a calorific value ranging from 3,800 to 3,900 cal/g, and with husk fiber comprising up to 75%, they ignite easily, burn efficiently, sustain prolonged combustion, and generate strong heat.

- Energy savings: With a dense and uniform structure and low moisture content, rice husk pellets minimize energy loss during combustion, ensuring optimal utilization of energy sources in the production process.

- Environmentally friendly: Derived from plant sources, burning rice husk pellets only releases CO2 equivalent to the amount absorbed during rice plant growth, reducing greenhouse gas emissions and environmental impact.

- Health safety: Rice husk pellets have low sulfur content, producing minimal emissions of foul odors or respiratory irritants during combustion. They produce less smoke and airborne ash compared to other fossil fuels, reducing air pollution and promoting human health.

- Cost-effectiveness: Abundant rice resources in Vietnam optimize raw material procurement and pellet production costs, resulting in rice husk pellets being priced 30 - 50% lower than other fuel types. Stable pricing and ample supply further aid in cost-saving for businesses, enhancing competitiveness in the market.

- Reducing dependence on fossil fuels: Amidst dwindling fossil fuel reserves, rice husk pellets offer a practical fuel alternative, reducing reliance on traditional fuel sources and ensuring production stability, thus mitigating energy crises.

- Versatility: Rice husk pellets are highly versatile and suitable for use as fuel in various traditional and modern boiler systems. Therefore, transitioning to rice husk pellets entails minimal infrastructure changes or additional investments, saving time, saving costs, and reducing production risks.

3. What is the price competitiveness of rice husk pellets?

The specific price of rice husk pellets depends on various factors such as quality, geographical location, production scale, and utilized technology. Quality is the most critical factor influencing prices.

Rice husk pellets meeting stringent standards for moisture content, ash ratio, fiber content, and environmental safety typically command higher prices than locally produced, less refined varieties.

4. Where to purchase rice husk pellets?

Currently, numerous commercial entities trade rice husk pellets. However, suppliers capable of in-house production offer more benefits to customers by ensuring product quality, guaranteeing continuous and stable supply, and providing technical support, and services tailored to customer needs.

As a reputable energy company with extensive experience, Thuan Hai leads in manufacturing and supplying rice husk pellets and various biomass fuels to the market, with an annual output of 1 million tons.
