life cycle assessment (LCA) refers to the compilation and evaluation of inputs and outputs and their potential environmental impacts during the life cycle of a product system. LCA considers the entire life cycle of the product, from the acquisition of raw materials, the production of energy and materials, the manufacture and use of the product, to the treatment of the product at the end of its life, and the final disposal. Through this systematic view, potential environmental load shifts can be identified and possibly avoided at all stages or links throughout the life cycle.
The study of LCA includes:
1. Determining the purpose and scope of the analysis;
2. life cycle inventory analysis, LCI;
3. life cycle impact assessment;
4. There are four stages of life cycle interpretation.
