The developed crucible furnace has the capacity to melts 30 kg of Al-Si alloy scraps in 20 minutes during which 7 litres of spent engine oil was used up at a flow rate of 5.833 x 10-6 m3/sec. The overall thermal efficiency of the developed crucible furnace was 46.74% on its performace evaluation. Its operating cost is cheaper since, spent engine oil is relatively available and the incessant increment in the price of fossil fuel will no longer have effects on the production costs. The performance of the equipment is better than the traditional ways of non-ferrous metals recycling exercise and its adequate implants for conversion of waste engine oil and Al-Si alloy scraps to wealth.
