Disposal of hazardous waste in the Cape Town area is designed to provide the maximum protection against environmental damage that can be achieved on a very limited budget. Wastes that are not expected to migrate from dry landfills, where the moisture content can be kept below 20%, are disposed of in trenches cut into filled domestic waste and resealed with clay. Other wastes, such as tetraethyl lead sludges, are blended into high strength concrete as part of road construction.
