Eni Eco Grease 2 is a biodegradable, light brown, anhydrous calcium grease, formulated with vegetable base oil. Eni Eco Grease 2 is expressly developed for the continuous lubrication of the bearings of the TBM (Tunnel Boring Machine) for the mechanized excavation of tunnels. It is also recommended for lost lubrication of agricultural and marble cutting machineries and of components operating in environmentally sensitive areas where contamination of the environment is a risk.
