waste removal


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.

Category Examples
Special Waste Asbestos
Clinical waste
Liquid Waste Flows at less than 5 degrees,  below 600C when transported, or is not capable of being picked up by a shovel
Hazardous Waste Lead paint
Dangerous Goods containers
Coal tar
Restricted Solid Waste Special assessment and classification required
General Solid Waste (putrescible) Waste from litter bins collected by or on behalf of local councils
Food waste
Animal waste
General Solid Waste
(non – putrescible)
Concrete, glass, plastic
Paper or cardboard
Garden waste


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.

At CETEC we can help you with:

  • Environment Site Assessments (ESA)
    • Phase I ESA – includes a desktop assessment of the site based on aerial photographs, historical land use, etc
    • Phase II ESA – Detailed investigation which collects samples of soil, groundwater or building materials to analyse for quantitative values of various contaminants. Normally undertaken when Phase I ESA determines a likelihood of site contamination
    • Phase III ESA – Investigation involving remediation of a site. Phase III investigations may involve intensive testing, sampling, and monitoring, “fate and transport” studies and other modelling, and the design of feasibility studies for remediation and remedial plans
  • Review of site ESA, Remedial Action Plans (RAP) and Environmental Management Plans (EMP)
  • Development of project specific ESA, RAP and EMP, and OHS Management Plans for contaminated soil
  • Soil stockpile waste classifications prior to removal from site
  • Clearance soil sampling following Underground Storage Tank (UST) removal

The involvement of an organization with a scientific OH&S approach is highly recommended given the increasingly cautious industrial relations and environmental regulations. CETEC is highly experienced in dealing with all the risks posed by hazardous materials and encourages their early and ongoing expert management.
