Waste Classification guidelines:


The South African waste classification regulation GNR 634 requires all generators of HAZARDOUS waste to classify their waste for road transport requirements.


Below are a few guidelines for you to consider prior to classification, Waste must be classified according to GHS – SANS 10234 “South African National Standard Globally Harmonized System of Classification and Labelling of Chemicals (GHS)”


• Waste must be classified within 180 days of generation

• Any waste that has been treated must be re-classified

• Waste must be re-classified if there is modification to the process or activity that generated the waste,


Wastes listed in Annexure 1 below do not need to be classified in terms of SANS 10234

Annexure 1 -do not need to be classified in terms of SANS 10234:


Domestic waste

  • Business waste not containing hazardous waste or chemicals

  • Uncontaminated building and demolition waste

  • Waste tyres

  • Garden waste

  • Post consumer packaging

  • Non-infectious animal carcasses

  • Uncontaminated, excavated earth

  • Hazardous Waste 2(b)

  • Asbestos waste

  • PCB waste or PCB containing waste

  • Expired, spoilt or unusable hazardous products

  • General waste (excluding domestic waste) which contains hazardous waste or hazardous chemicals

  • Mixed hazardous chemical waste from analytical or academic laboratories in containers less than 100 litres

  • Health care risk waste


General Requirements:

  • Generators must ensure their waste is re-used, recycled, recovered, treated and/or disposed of within 18 months of generation

  • Waste managers must not store waste for more than 18 months from the date of receipt of the waste

  • Waste that was stored in an existing facility prior to promulgation of the Regulations must be re-used, recycled, recovered, treated or disposed of within 5 years of the commencement of the Regulations.

  • Waste may not be diluted to solely to reduce the concentration of its constituents for purposes of classification or assessment for landfill disposal

  • Waste containers must be labelled, or where labelling is not possible, records must be kept, reflecting:

    • Category of waste as per the Waste Information Regulations, 2012

    • Date of containerisation

    • Date when container was filled, sealed or covered

    • Classification of the waste.


Waste Treatment


Waste may not be mixed or treated where this would

  • Reduce the potential for re-use, recycling or recovery -Or – Where the treatment is not controlled

  • May blend or pre-treat the waste to – Encourage the re-use, recycling, recovery or treatment, or

  • Reduce the risk of the waste


SDS generation

Generators of hazardous waste must ensure a safety data sheet is prepared and accompanies the waste at all times


• Holders of hazardous waste (excluding HCRW) must be in possession of the relevant SDS for the waste

• Contents of SDS as per SANS 10234:

  • Source and composition of waste

  • Hazard’s identification

  • Physical and chemical properties

  • Toxicological and ecological effects

  • Transport

  • Disposal options

  • First aid/fire-fighting measures

  • Handling and storage


Consequences and deadlines

Landfills are instructed not to receive wastes that aren’t classified; The deadline which was in August 2016, was to have all waste excluding waste listed in Annexure 1 above classified according to the new regulations.

SAWIS /GWIS Registration guidelines:

The South African Waste Information Regulation GRN 625 (NEMA (59/2008). states that all HAZARDOUS WASTE generators must register onto the system. Effective since 13 Aug 2012. These regulations don’t apply if you only generate general waste.

Trigger for generators – Generators of hazardous waste in excess of 20kg per day.

Here are the steps below:

Go to http://sawic.environment.gov.za click on central registry or http://www.gwis.gpg.gov.za/pages/display/register


   1  If you want to read about who should register – click who should register.

   2   You can also select to confirm you aren’t registered before completing the registration process.

   3   Select Register

   4   Select the drop down and select your and .

   5   Complete the registration form and click on the button.

         awaiting authorisation.

   9   You will be sent a second email upon the approval of your registration. This will contain the unique                   registration number, a username and password, which may be used to log onto the website to         

         update or amend information as and when required.

   10  Final step: Obtain SAWIS certificate



What happens if you do not register?

The waste regulation GNR 625 stipulates that all HAZARDOUS WASTE generators must comply and failing to comply or providing incorrect/misleading information, if convicted, will result in:

  1. Imprisonment for a period not exceeding fifteen (15) years;

  2. An appropriate fine;

  3. or both a fine and imprisonment


Further to this, hazardous waste management facilities refuse to accept waste from generators without a valid WIS number which means waste cannot be removed off site.

Hazardous Waste:

What is Hazardous Waste?

Definition according to NEMWA (National Environmental Management Waste Act):

"hazardous waste" means any waste that contains organic or inorganic elements or compounds that may, owing to the inherent physical, chemical or toxicological characteristics of that waste, have a detrimental impact on health and the environment;                                                                                       


"general waste" means waste that does not pose an immediate hazard or threat to health or to the environment, and includes—

(a) domestic waste;

(b) building and demolition waste;

(c) business waste: and

(d) inert waste

Dangerous Goods according to the NRTA 93 of 96 (National Road Traffic Act 93 of 1996):


Classification of Dangerous Goods by UN Class


There are nine UN Classes of Dangerous Goods:

  1. Explosives

  2. Gases

  3. Flammable Liquids

  4. Flammable Solids

  5. Oxiders

  6. Toxic and infectious substances

  7. Radioactives

  8. Corrosives

  9. Miscellaneous


Each UN Class and sub-class is represented by a unique hazard diamond
