This work on Cleaner Production Assessment in the downstream Petroleum Lubricants Industry value chain focuses on Cleaner Production opportunities available to reduce negative environmental impacts of lubricants throughout the value chain from blending to disposal. Some effort was made to investigate existing cleaner production practices by manufacturers and end users of lubricants. As well as establishing gaps in the implementation by stakeholders for which options were generated to improve on the current practices. Issues on base oil substitution, minimizing oil losses during and after manufacturing, raw material and energy consumption reduction, and environmentally friendly used oil disposal were reviewed as way forward for effective Cleaner Production for the industry. Hence this work will act as a resource for managers in the lubricants industry both manufacturers and consumers to understand Cleaner Production aspects and incorporate Cleaner Production practices in their operations for regulatory compliance, environmental protection and business competitiveness in terms of savings achieved.
