When creating a waste fraction, you need volume to mass conversions so that the Diligent ESG system can normalize waste data by either a mass unit or a volume unit altogether. 

We recommend that you download and use the WRAP volume-to-mass conversion excel sheet when reviewing what your volume to mass conversion is: 

WRAP volume-to-mass conversion 


In the Conversion factors tab, there is an array of waste streams. Search for an appropriate description for your new waste fraction and you can see the conversion factor stated in line with this waste stream. 

If you are using this WRAP tool when inputting your volume-to-mass conversion, we recommend that you use the following options:

  • In the From Unit dropdown, select cubic metre.
  • In the From Unit dropdown, select tonne.
  • In the Conversion Factor field, use the conversion factor identified within the WRAP excel sheet.
