HW 12 – Tarry and Bituminous waste

Waste from coal based generated tar and petroleum based manufactured bitumen (including asphalt).

No national data on this waste stream is available in literature. In Gauteng, poisonous and toxic waste reported as consisting predominantly of coal tar and pitch (770.57 t/a) (GDACE, 2006).
The data reported in the baseline waste obtained from relevant waste management companies.

HW 13 and GW 13 - Brines

This waste stream refers to water containing salts, mainly as a result of industrial effluent treatment.

The major industries contributing to the inland volume and salt load are:

• 
  Mining;
  
• 
  Power generation;
  
• 
  Paper & pulp;
  
• 
  Petroleum;
  
• 
  Steel & metals processing (Van der Merwe et al. 2009).
  

Discharges of salt to the marine environment were not considered although a considerable amount of brines is discharged to sea .

Brine volumes are generally reported. According to a study that was conducted for the Water Research Commission, a total of just over 530 000 kℓ/d of effluent is discharged to inland systems, containing approximately 1 060 t/d of salt (Van der Merwe et al, 2009). The figures quoted by this research are considered to be accurate as it is based on questionnaires completed by the industry.
A summary of industry sectors generating brines, the volumes of effluent and salt load to the environment is provided in Table 12.
