Waste does not just refer to rubbish and unwanted material, but also includes:
- Excavated material such as dirt, sandstone and soil
- Construction, building and demolition waste such as asphalt, bricks, concrete, plasterboard, timber and vegetation
- Asbestos and contaminated soil
- Liquid, solid and gaseous products
According to the NSW EPA waste classification guidelines all waste must be classified into one of six possible classifications.
Different types of classifications and the type of waste which falls under each category are shown below.
||Flows at less than 5 degrees, below 600C when transported, or is not capable of being picked up by a shovel
Dangerous Goods containers
|Restricted Solid Waste
||Special assessment and classification required
|General Solid Waste (putrescible)
||Waste from litter bins collected by or on behalf of local councils
|General Solid Waste
(non – putrescible)
|Concrete, glass, plastic
Paper or cardboard
The type of classification determines how the waste must be managed. The particular classification of waste will determine:
- the kind of facility that may be used to dispose of waste
- whether a license is required to dispose of, transport, process or otherwise manage the waste
- whether movement of the waste must be tracked
For older buildings, industrial premises or specialist facilities there can be a complex matrix of potential hazardous materials; e.g. asbestos, chemicals, radioactivity and biohazards.
