City of Ryde Council
Top Ryde, NSW
  • Waste classification
  • Waste disposal consultation.

Project challenges

The site was an operational car park. Council wanted to assess the soils to provide a waste classification for off-site disposal of surplus excavated materials.

Our solutions

We designed a waste classification assessment to provide the most cost-effective solution for off-site disposal and/or re-use of the material. This included an assessment under Part 1 of the Waste Classification Guidelines and a preliminary screening of the waste against the Excavated Natural Material (ENM) criteria. This screening  found the soil parameters exceeded the ENM thresholds, which meant there was no need for any further assessments, resulting in an overall cost saving.
