iEnvi completed an in‑situ waste classification and Excavated Natural Material (ENM) assessment for a Southern Highlands council road upgrade. Of 20 samples collected at 30 m intervals, 17 met ENM criteria, two were restricted solid waste and one was hazardous — enabling reuse of most material and avoiding excavation‑stage delays.
iEnvi assessed a 1,800 m3 soil stockpile for an inner-west Sydney council to determine suitability for reuse. Targeted test pits and laboratory analysis showed the material generally met the Excavated Natural Material Order 2014 criteria but required processing and a Specific Resource Recovery Order/Exemption from the NSW EPA before reuse as bunding engineering fill.
Shallow soil testing at a residential site in Morningside prior to construction of a childcare centre found concentrations below regulatory assessment criteria for human health and ecological receptors. Soil was considered low risk and no further action was required. Reuse options may now be considered prior to offsite removal.
iEnvi supervised a 2019 resource-recovery program to reuse road asphalt millings as engineering fill for new sports fields. About 19,755 tonnes from 56 roads were reused under Recovered Aggregate Order requirements and assessed suitable for public open-space use.
iEnvi provided a site-specific, commercially focused remediation program for a Western Sydney coatings manufacturer, combining UST removal, source-zone treatment and a four-month Multiphase Vapour Extraction campaign to manage solvent impacts and restore asset value.
