This makes Waste management responsible for challenging the impacts of such waste on the environment and the high treatment costs. This study reviews previous research and studies that have been carried out to investigate and address several issues regarding sustainability, especially the management of raw materials and waste, relying on management methods such as Lean six sigma. Furthermore, this study explores the difficulties that hinder oil companies and oil refineries from being more sustainable.Energy sources such as gas, oil and coal are significantly used due to worldwide energy consumption. Such use could be increased by 37 per cent in 2035. This increase comes from population growth, reaching 25 % in the next 20 years. In order to apply sustainability systems in these institutions, an account of economically affordable and with minimum impact to the environment and technological viability must be considered. There are stringent regulations and scrutiny in the environment of using oil refining industries to be more sustainable worldwide.Management Framework
