Economical and Environmentally production process
JIC is the first and the only one that succeeded in inventing theproduction process using rice husk. Rice husk is used as energies forreaction of raw materials and drying formed products. The rice husk ash
is used for as a raw material instead of Silica rock. This unique process
is certificated as an environment-conscious business by Viet NamGovernment. The process contributes to reduce 4,200 ton CO2 / year.
