Composting process by using palm oil mill effluent (POME) aerobic sludge, decanter cake and rice husk ASH

Palm oil mill industry had contributed to significant pollution especially river pollution when they discharged their effluents such as POME sludge and decanter cake into the rivers. To solve the environmental problem, these wastes can be utilized as fertilizer through composting process. However, t...
