Effect of rice husk ash on the physiochemical properties of compost

The production of rice husk (RH) in Malaysia kept on increasing due to high demand of rice. In order to dispose the RH, it was utilized as industrial fuel through incineration process in the boiler to generate steam to provide electricity. Through incineration process, rice husk ash (RHA) was produc...
