Waste
Construction Waste Calculator
Estimate construction waste generation and disposal quantities.
Use a project-specific or locally appropriate waste generation rate.
Optional. Leave blank if cost calculation is not required.
Optional processing or recovery cost per tonne of diverted material.
Estimated Construction Waste
–
Estimated total waste generated from the entered project area and waste generation rate.
Total waste generated
–
Waste diverted / recycled
–
Waste sent to disposal
–
Diversion rate
–
Disposal rate
–
Waste generated per m2
–
Disposal cost
–
Recycling / recovery cost
–
Total waste management cost
–
Method:
Total Construction Waste =
Project Area x Waste Generation Rate
Diverted Waste =
Total Waste x Diversion Rate
Waste Sent to Disposal =
Total Waste – Diverted Waste
Disposal Cost =
Disposed Waste x Disposal Cost per tonne
Recycling / Recovery Cost =
Diverted Waste x Recovery Cost per tonne
Total Waste Management Cost =
Disposal Cost + Recycling / Recovery Cost
All calculations are converted internally to square metres, kilograms and tonnes.
The waste generation rate should be selected carefully because construction waste varies substantially with project type, material mix, construction method, renovation activity, demolition intensity and local practices.
This calculator is intended for preliminary waste planning and reporting, not detailed material take-off.
