START

Fill out your input concerning the product(s) you produce and for which you want to define a mass balance below. Please make sure all input concerns the same time frame (e.g. a year) and is in the same unit (e.g. ton or kg). The tool is meant as a starting point, though not applicable for a full mass balance. Consumables and emissions to water and air are not taken into account into the calculation of the losses in the mass balance.

By default all input fields are unlocked and allow input. If you are certain and you do not want to change a specific number anymore, you can toggle the lock behind that input field.

If you feel the visualisation of the mass balance is too small you can widen your screen or go to full screen.

This Mass Balance tool was produced by Fontys as part of the RAAK research project Circular Entrepreneurship for SME’s, which is co-financed by the Taskforce for Applied Research SiA, part of the Dutch Research Council NWO.
