Why choose concrete recycling for construction materials?

Often construction waste contains concrete which causes the waste to be treated as a heavy general waste due to its weight. Keeping the concrete separate from the other construction waste will seriously reduce the cost of disposing of unwanted or rubbish construction materials. Concrete waste weighs between a tonne and 1.5 tonne per cubic metre. By removing the heavy concrete material you will avoid paying waste levies on the disposal of the concrete and keep the concrete out of the landfill. In NSW the waste levy is approximately $150 a tonne so diverting concrete from landfill could save your project $600 on a 6 metre bin of concrete.

The best way to recycle concrete waste

Avoid mixing your waste concrete with other waste materials. Sorting concrete to be recycling out of mixed waste is a time consuming task that will cost you which is why it is best to keep it separate in the first place. The concrete from demolishing building, driveways and footpaths should be placed directly into a skip bin or stockpiled separatly until ready to be placed in a bin.

  • Road base for driveways

  • Road construction

  • new road construction projects

  • Backfill for drainage behind retaining walls

  • new concrete for concrete products line roadside barriers
