Energy and chemicals group Sasol is aiming to begin ramping up internal coal production and reducing external coal purchases after its destoning plant reached beneficial operation in December. CEO Simon Baloyi said the project, which involved a repurposing of the Twistdraai export coal plant, had been completed within its budget of about R700-million and was facilitating the delivery of coal to Sasol’s Secunda Operations with a total sinks content of about 12%.
