Green maintenance refers to maintenance practices that reduce environmental impact while ensuring the reliability, safety, and efficiency of industrial equipment and facilities. In Maintenance Management, it integrates environmental considerations with traditional objectives such as equipment availability, cost reduction, productivity, and safety. Green maintenance supports sustainable development by promoting efficient use of resources, reduction of waste and emissions, and longer equipment life. A major aspect of green maintenance is improving energy efficiency. Regular inspection, cleaning, lubrication, calibration, and alignment of machines can reduce energy losses and improve operating efficiency. Predictive maintenance technologies such as vibration monitoring, thermal imaging, oil analysis, and sensors help identify equipment deterioration at an early stage. Properly maintained motors, pumps, compressors, boilers, and HVAC systems generally consume less energy and produce fewer emissions. Thus, effective maintenance contributes directly to energy conservation and carbon reduction. Green maintenance also emphasizes extending the useful life of equipment. Preventive and condition-based maintenance can prevent premature equipment failure and reduce the need for frequent replacement. Longer equipment life reduces the consumption of raw materials, energy, and other resources required for
