Life cycle inventory (LCI) is the methodology step that involves creating an inventory of input and output flows for a product system. Such flows include inputs of water, energy, and raw materials, and releases to air, land, and water. The inventory can be based on literature analysis or on process simulation.
People also ask
What is life cycle inventory of a product?
Life Cycle Inventory analysis (LCI) is defined as a phase of Life Cycle Assessment (LCA) involving the compilation and quantification of inputs and outputs for a given product system throughout its life cycle [1].
What are the steps in life cycle inventory analysis?

These standards describe the four main phases of an LCA:

1
Goal and scope definition.
2
Inventory analysis.
3
Impact assessment.
4
Interpretation.
What are the 5 stages of a life cycle analysis?
There are 5 Main Life Cycle Stages. Everything that is produced goes through these five main life cycle stages: materiel extraction, manufacturing. packaging and transportation, use and end of life. At each of these stages, there are inputs and outputs, flow-throughs, value losses, and potential gains.
What's the difference between LCA and LCI?
The process is naturally iterative as the quality and completeness of information and its plausibility is constantly being tested. LCI is the life cycle inventory, which is the data collection portion of LCA. LCI is the straight-forward accounting of everything involved in the “system” of interest.
