Major problem due to the hazardous waste in a petroleum industry is mainly coming from the disposal of oil refinery sludge (ORS). ORS consists of heavy metals and other constituents which are very dangerous to human health and also can pollute the environment. The aim of this study is to reduce the amount of oil and grease level in ORS using aerobic composting. Oil refinery sludge was taken from PETRONAS Penapisan (Terengganu) Sdn. Bhd. from Oily Float Tank (T-3006) KR1, crude tank D901, D902 and D903, and from Corrugated Plate Interceptor (CPI) compartment. Thus ratio of ORS, bulking agents and seeding material was 1: 1: 0.5. ORS to bulking agent was 1: 1 (v/v), while ORS to seeding material was 1: 0.5 (w/w). Recycle office papers were collected at the printing room academic building UTP, and the dry yard wastes consist of leaves and branches which are dry and brown in color were collected from the area near the hostel where it is filled with trees which are fully grown. Sewage sludge was taken from PETRONAS Penapisan (Melaka) Sdn. Bhd. at the waste water clarifier and was used as seeding material in the compost pile. Two different mixtures was been introduced in the same ratio amount. The composter was made in cubic containers with dimension (0.25m x 0.25m x 0.25m). Opened at the top and with small holes in the bottom and side, and been wrapping with rice bag (fabric). Oil and grease level, temperature, pH, C: N ratio and moisture content were monitored during composting. Composter 1 and 2, working under the similar condition, which recorded temperatures was between 31-35°C, and moisture content (50-60%), with optimum pH level (6.5-8.0). The maximum oil and grease reduction was 55.9 % starting from week 1 to week 14 experimental period in compost 2, using shredded papers as a bulking agent
