Jurong Island is a man-made island located off the southwestern coast of Singapore. It was created by joining several smaller islands and is primarily used for industrial purposes, particularly in the petrochemical sector. The island hosts numerous chemical plants and facilities, making it a key part of Singapore's economy. The development of Jurong Island began in the late 1990s, and it has since become a hub for multinational companies in the energy and chemical industries. The island is connected to the mainland by a bridge, allowing for easy transportation of goods and workers.
