Hitachi Industrial Equipment Systems Co., Ltd. has introduced a new plant-based lubricant, GREEN SCREW OIL, for oil-flooded screw air compressors, significantly cutting CO2 emissions during manufacturing.
The lubricant, derived from plant materials that absorb CO2 through photosynthesis, reduces manufacturing-stage CO2 emissions by approximately 90% compared to conventional synthetic oils. Across its entire lifecycle, including disposal, it can cut emissions by about 40%.
GREEN SCREW OIL maintains performance on par with traditional synthetic oils and offers a two-year replacement cycle. The initiative aligns with Hitachi's sustainability strategy, PLEDGES, which promotes decarbonization under its Planet pledge.
Hitachi plans to expand the use of GREEN SCREW OIL to its Global Air Power's oil-flooded screw air compressors under the Sullair brand and its oil-free air compressors. The company estimates that replacing all lubricants in its air compressors with plant-based alternatives could reduce CO2 emissions by over 2,000 tons annually.
The launch is part of Hitachi's broader strategy to enhance the environmental value of digitalized assets and support sustainable industrial sites. The company's Connective Industries Sector aims to expand its HMAX Industry solutions, which integrate AI and digital technologies to innovate social infrastructure and industrial operations.
HMAX Industry, part of Lumada 3.0, leverages AI and Hitachi's domain knowledge to provide predictive diagnostics and operational support, enhancing efficiency and sustainability in various sectors, including manufacturing and social infrastructure.
