Recycling oils is the process of collecting waste oils and passing them into processes including filter, hydrogenation and mixing, in order to extract valuable materials and separate them from non-useful materials, for reuse again. There are objectives of recycling oils including: • Reduce the rate of waste on the surface of the globe. • Prevent the waste oils to leak to agricultural land, groundwater, and water dams, as one gallon of waste oil can pollute one million gallons of water. • Reduce the cost of production, because the cost of recycled materials is less than the cost of new materials. • Energy saving, as the energy needed to produce refined materials is lower.
