Hitachi Industrial Equipment Systems Co., Ltd., has launched ‘Green Screw Oil’, a plant-based lubricant for oil-flooded screw air compressors. Because the plant-derived raw materials absorb CO₂ during growth, the new lubricant cuts manufacturing stage CO₂ emissions by approximately 90%. Even including emissions at disposal, its CO₂ emissions across the entire lifecycle can be reduced by approximately 40% (estimated value) compared to conventional synthetic oils.
Air compressors are widely used in manufacturing and social infrastructure fields. HIES’ air compressors form a significant part of the installed base for ‘HMAXTM Industry’, a digital service that embodies Lumada 3.0, offering predictive diagnostics powered by machine learning and operational/maintenance support through generative AI. Delivered via ‘FitLiveTM’. These solutions support efficient and sustainable operations. Aligned with Hitachi’s sustainability strategy ‘PLEDGES’, which is based on the management plan ‘Inspire 2027’, and promotes decarbonization under the P: Planet pledge, ‘Green Screw Oil’ further enhances the environmental value of digitalized assets and supports the creation of more sustainable industrial sites.
Oil-flooded screw air compressors require lubricants to prevent component wear and provide cooling, as a pair of screw rotors rotate at high speeds to compress air. Conventional lubricants are derived from crude oil, and CO₂ is emitted during their manufacturing process. ‘Green Screw Oil’ uses plants as raw materials that absorb CO₂ through photosynthesis. This means that during manufacturing, CO₂ emissions are reduced by 90%. Even when considering the disposal stage, total emissions are reduced by 40%.
