Hitachi Industrial Equipment Systems (HIES) has introduced ""GREEN SCREW OIL,"" a plant-based lubricant designed for oil-flooded screw air compressors. By utilising plant-derived raw materials that absorb CO? during growth, this lubricant reduces CO? emissions during manufacturing by approximately 90 per cent. Over its entire lifecycle, including disposal, CO? emissions are reduced by 40 per cent compared to conventional synthetic oils.

This product aligns with Hitachi's sustainability strategy, supporting decarbonisation under the ""PLEDGES"" framework and enhancing the environmental value of digitalised assets. ""GREEN SCREW OIL"" is equally effective as conventional lubricants, with a recommended two-year replacement cycle.

HIES plans to extend this initiative to the Hitachi Global Air Power’s air compressors, further advancing sustainability across the group’s global operations. With a significant market share in air compressors, Hitachi estimates that replacing all lubricants with plant-based alternatives could save over 2,000 tons of CO? annually.

This initiative supports Hitachi’s goal of driving innovation in industrial automation, contributing to a more sustainable and efficient industrial environment through its “HMAX Industry” digital solutions.
