C5.3.2 Inventory Analysis Phase


The Inventory Analysis Phase requires data collection and verification. This phase is an inventory of the inputs and outputs to the processes being considered.

Example Inputs:

  • Raw Materials
  • Energy
  • Chemicals


Example Outputs:

  • Air Emissions
  • Water discharges
  • Waste


This process is often conducted using dedicated software packages.

It is important that the data is suitable for comparison and therefore it should be normalised. For example, x kg of solvent emissions to air, per unit of product.
