At present, Khai Nguyen Company is procuring sawdust to make pellets for export to foreign countries. According to technical analyses, sawdust pellets produce heat equal to 70 per cent of coal but prices equal only 45 percent. Compared with diesel oil (DO), sawdust generates an equivalent of 48 per cent heat but the price is less than 30 per cent. On average, two kilograms of sawdust pellets equal one kilogram of diesel oil. Thus, with the same amount of energy generated, the use of sawdust pellets will help save some 50 per cent of product cost. Sawdust pellets cause less pollution than coal. For this season, this product is very popular in Europe and other advanced countries such as Denmark, Italy, Thailand, South Korea and Japan. According to some export companies, compressed sawdust has export value 2-3 times greater than unprocessed sawdust.

Because sawdust pellets do not contain impurities such as in coal, the amount of discharged carbon dioxide is very low. Wood pellets meet European air standards. For 1,000 kg of wood pellets burned, the remaining ash weighs 10-15 kg and is a kind of biomass used to fertilize crops. European people used sawdust pellets to heat and cook instead of gas, firewood and wood. The use of wood pellets not only brings in revenue but also helps deal with waste in production, environmental pollution, fire and explosion. In light industries, wood pellets are used for heating boilers, and for dryers in the garment, food industries.

Currently, in Vietnam, many companies are using wood pellets for cooking, including Royal Hotel (Quang Ninh province) and Lightweight Brick and Concrete Company (Hanoi). Ms Nguyen Huynh Nguyen Thuy, Director of Khai Nguyen, said the company is trying to introducing wood pellets to domestic users after conquering the world because Vietnamese people should know and use good Vietnamese products.

In the coming time, Khai Nguyen will upgrade its production capacity. Currently, many businesses are purchasing and using sawdust as materials for combustible production.
