South Africa has one of the world's highest dependencies on coal as a primary source of energy, with approximately 90 % of the energy derived from coal (Horsfall, 1992). In addition to this, coal is also a major energy and reductant source for the world's metallurgical industries in which South Africa is a major player.

In Europe, for example, coal tar was blended with bitumen and used in all layers of paving until oil production increased and coal fell out of economic favour in the 1970s and 1980s. Coal tar was eventually phased out in Europe in the 1990s and controls were put in place to prevent coal tar from re-entering pavement as a result of recycling.
