Sasol has built three cities in the middle of nowhere and one is entirely underground

• Sasol has built three cities in the middle of nowhere and one is entirely underground: Sasol has built an entire city above and below ground to power its Secunda operations, including a 65-kilometre underground tunnel network.
• The Secunda facility hosts 16,000 to 20,000 workers daily under normal conditions, and doubles to 50,000 during maintenance and upgrades.
• The high labour demand at Sasol's Secunda facility has implications for the company's operations, with CEO Simon Baloyi stating that the site is critical to South Africa's energy security and plays a key role in meeting nearly a third of the country's fuel demand.
