Abstract

Coal is the primary source of energy in South Africa today. In the extraction and processing of coal, significant amounts of coal fines waste are generated. Currently, waste coal fines have no economic value. As a result, they are disposed of in landfills or underground. Furthermore, if coal fines are not properly managed, they have a negative environmental impact including spontaneous combustion, groundwater contamination, acid mine drainage, and wind-driven air pollution. When inhaled, coal fines, can cause lung disease (black lung disease) and other health problems. However, coal fines have the potential to be used as a source of energy. The aim of this work was to produce coal fines briquettes using varying ratios of natural binders such as cactus. The integrity of the briquettes was assessed using shattering index. The briquettes produced using 10% cactus paste by mass exhibited the best shattering index of 86%, which is sufficient for good storage and handling of the briquettes. Further work will be required to assess the combustion behaviour of the briquettes for domestic and industrial energy applications.
