Waste management

The Environment Protection Act 1993 and Environment Protection (Waste to Resources) Policy 2010 define 'waste', and set out the regulatory requirements for waste management activities. One of these requirements is the implementation of the waste management hierarchy, which prioritises various waste management approaches.

In accordance with the hierarchy, avoiding waste generation is the most preferable, with disposal only occurring where other waste management options such as reuse, are not possible. In applying the waste management hierarchy and protecting the environment, the EPA seeks to:
  • Promote the best and safest use of recovered resources, and
  • Reduce the amount of waste going to landfill and ending up in our environment.

A circular economy is a self-sustaining system which aims to keep materials in use, or ‘circulating’, for as long as possible. It extracts the maximum value from materials such as soils while in use, then recovers and reuses them in other forms.

The 2 waste streams which will be relevant during T2D early works include management of waste soils and construction and demolition waste. In accordance with EPA regulatory requirements, the options for both waste streams in South Australia include reuse, treatment or disposal. Examples of reuse include where waste soil is reused for levelling land associated with infrastructure development, or where construction and demolition waste (eg concrete) is processed into aggregate to be used as road base.

In 2020, the Department for Infrastructure and Transport (DIT) began a soil and water survey program to test relevant geotechnical, hydrogeological and contamination conditions close to South Road. This program is continuing, though once complete it will assist in the determination of the most appropriate waste soil management option(s) when T2D construction work begins. It will also enable the EPA to ensure that waste soils are being diverted from the project to the most appropriate location.

Waste transportation will also be an important consideration in the early works of the T2D. In accordance with the Environment Protection (Waste to Resources) Policy 2010 a person who transports waste, including waste soil and construction and demolition waste, must take all reasonable and practicable steps to cover, contain or secure the waste. Depending on the waste that is being transported, an EPA License may be required and the waste must be tracked.

As further details are made available by DIT in regard to the T2D project, this website will be updated. If you would like to learn more about the T2D Project, please sign up to receive electronic updates or download fact sheets
