Crumb rubber production is an energy intense process that requires proper monitoring to avoid energy waste. Owing to the high cost of energy and its impact on production cost, an energy audit of Imoniyame Holdings Limited is necessary for production cost reduction and to remain relevant in a competitive environment. A one year energy audit of the plant was carried out. Detailed performance data were collected for the major energy consuming sections of the plant. These were the oven, production lines and the lighting sections. From the work, the energy consumed by the oven for the period of audit was 9,472.32GJ which was 53.6% of the total energy of 17,614.343GJ consumed for the period. The oven is therefore recognized as having the highest energy saving potentials. The specific energy consumption and the specific energy cost of the plant were 4.298MJ/kg and N13.87/kg of crumb rubber respectively. The heat losses through the stack can be recovered by the introduction of a heat exchanger between the stack and the circulating water. It was shown that when this is done, an annual savings of N3,204,929.56 will be made from the cost of diesel fuel. It was also ascertained that the specific energy consumption and the specific energy cost will be reduced to 3.99mJ/kg and N13.09/kg of crumb rubber respectively.
