Life cycle analysis (LCA) is a method used to evaluate the environmental impact of a product through its life cycle encompassing extraction and processing of the raw materials, manufacturing, distribution, use, recycling, and final disposal.
Also asked, what are the 5 stages of a life cycle assessment?
As noted above, the inventory in the LCA usually considers a number of stages including: materials extraction, processing and manufacturing, product use, and product disposal.
Likewise, what are the 4 stages of a life cycle assessment?
The standards are provided by the International Organisation for Standardisation (ISO) in ISO 14040 and 14044, and describe the four main phases of an LCA:
- goal and scope,
- inventory analysis,
- impact assessment.
- and interpretation.
What is life cycle analysis used for?
Life cycle assessment is a cradle-to-grave or cradle-to-cradle analysis technique to assess environmental impacts associated with all the stages of a product's life, which is from raw material extraction through materials processing, manufacture, distribution, and use.
How do you perform a life cycle analysis?
- Step 1: LCA goal & scope definition. The goal & scope definition ensures the LCA is performed consistently.
- Step 2: Inventory analysis of extractions and emissions.
- Step 3: Impact assessment (LCIA)
- Step 4: Interpretation.
