Parkwood Recycling Estate Clean Up

Parkwood Recycling Estate Clean Up (Skippy Bins)

Location: West Belconnen, ACT
Client: ACT Property Group
Start: November 2015
End: December 2015

The Details

Goldsmith was engaged under emergency conditions to assist with the clean-up of Parkwood Recycling Estate (Skippy Bins), following an uncontrolled fire within the stockpiled waste material. Acting on very short notice, Goldsmith provided heavy equipment, operators, supervision and engineering support 24 hours per day, 7 days per week, to assist the fire department and other contractors to put out the fire in waste material. Goldsmith then relocated the material to the neighbouring West Belconnen Resource Management Centre, where our equipment spread and soaked the material, before relocating and placing it in its final location within the landfill cell.
