Neste Oil, a Finnish oil and refining company placed its focus on NExBTL diesel. The Company has committed SGD1.2 billion to construct a plant in Singapore to produce NExBTL, with an annual capacity of 800,000 metric tons. The investment forms part of Neste Oil's strategic goal of becoming the world's leading renewable diesel producer. By incorporating ROCKWOOL insulation in the construction of the refinery, it has greatly contributed to the company's green initiative. The use of RockTech slab, sectional pipes and wired mats to insulate the boilers, vessels and hot pipelines throughout the plant prevent the loss of heat which translates to great energy savings. ROCKWOOL insulation is also able to provide protection for personnel and reduce the emission of noise thus creating a safe and conducive work environment.
