It operates one of South Africa’s largest fleets of yellow plant equipment and manages complex bulk water schemes. Operations include:

Eskom Rotek Industries Bulk Material Services is also responsible for the commercialisation of coal combustion products.
Coal Combustion Products
Ash and gypsum are no longer classified as hazardous waste and their beneficiation no longer requires licenses. Through a dedicated Ash Office, Eskom Rotek Industries is the central contact for the sale and commercialisation of coal combustion products, namely coal ash from Eskom coal fired power stations and gypsum from the Kusile Power Station flue gas desulphurisation plant.


Legislative requirements changes
Fly ash, coarse ash, clinker ash, mixed ash, cenospheres and gypsum are available for purchase by ash off-takers at various power stations, with samples provided for trial runs and testing. To ensure compliance with exclusion regulations and promote fairness and transparency, coal combustion products are sold through a tendering commercial process. Please check the Eskom tender bulletin for advertised tenders for coal ash and gypsum.
