Rubber latex drying cost reduced sharply by using rice husk instead of oil

TMr. Nguyen Duy Linh, General Director of Chu Se - Kampong Thom Rubber Joint Stock Company (Kampong Thom province, Cambodia), said since the price of diesel oil (DO) keeps highly increasing in recent years, the company has invested in a furnace heat system with the use of rice husk to replace the DO.

The results show that using rice husk instead of DO in drying rubber latex has helped the company reduce costs by 20-25% while increasing its product quality.

The rice husk source that Chu Se - Kampong Thom Rubber JSC uses in drying rubber is purchased right in the local area. Linh said it was very large but the company still signed contracts with local rice mills to proactively get adequate supply for production.

To dry 1 ton of rubber latex, the company has to use nearly 150kg of rice husk. In 2021, It consumed a total of nearly 4,000 tons of rice husk. Chu Se-Kampong Thom Rubber JSC is a member of the Vietnam Rubber Industry Group (VRG) in Cambodia.

It has two investment projects in Cambodia, C.R.C.K.2 and Bean Heack with a total area of ​​​​nearly 16,300ha, located in the triangle area that includes three provinces of Kampong Thom, Siem Reap, and Preah Vihear. Its rubber latex processing factory is the largest of Vietnam's rubber industry with a total capacity of 32,400 tons/year.
