• Conclusion

Hazardous waste can be defined as…

waste that has the potential, even in low concentrations, to have a significant adverse effect on public health and the environment because of its inherent toxicological, chemical and physical characteristics

WASTE MANAGEMENT LEGISLATION

• National Environmental Management Act, 1998 (Act 107 of 1998)

• Environment Conservation Act (Act 73 of 1989) Section 20

• National Water Act (Act 36 of 1998)

• Health Act (Act 63 of 1977)

• Air Quality Act (Act 39 of 2004)

• Hazardous Substances Act (Act 15 of 1973)

• Nuclear Energy Act (Act 131 of 1993) Section 45&46 Authority over management of radioactive waste, storage of irradiated nuclear fuel, discarding of radioactive waste and storage of irradiated nuclear fuel.

• General Regulations made in terms of the Medicines and Related Substances Act, 1965 (Act 101 of 1965) Section 27

• Occupational Health and Safety Act (Act 85 of 1993)

PRINCIPLES OF WASTE MANAGEMENT

• Duty of Care Principle

• Polluter Pays Principle

• Precautionary Principle

• Sustainable Development

OBJECTIVES OF HAZARDOUS WASTE MANAGEMENT

• To ensure the correct identification and classification of a hazardous waste

• To prevent hazardous waste entering the environment illegally.

• To implement “cradle-to-grave” principles by means of planned waste management strategies

• To manage hazardous waste until it is safely disposed of, by setting minimum requirements at crucial points in its life cycle

CURRENT SITUATION IN THE RSA

• Material Safety Data Sheets

• Composition of Hazardous Waste

• Chemical Reactions

• Laboratory Fees and Specialists

• Understanding the Minimum Requirements

• Enforcement of legal Requirements

INCORRECT MANAGEMENT OF HAZARDOUS WASTE

• Pollution of the Environment

• Impaired Health

• Slows down Socio-Economic Development

• Incomplete Mission
