Sappi Southern Africa turned this challenge into an opportunity by establishing a demonstration plant for manufacturing fuel rods at Ngodwana Mill. The rods, which comprise a mixture of waste coal slurry (from discarded thermal-grade coal fines), biomass and lignosulphonates, have been tested in one of the boilers at Tugela Mill. Positive results have been achieved and we have now established at a pilot plant at Tugela Mill.
