Environmental Activities for the Classroom: Product Life-Cycle Analysis

摘要

Dissecting a consumer product into all the variousprocesses that contribute to its production and disposalcan help us better understand how our consumer habitsaffect the environment. Consumption of productsdrives an array of extraction, manufacturing, processing,transportation and disposal operations. An analysisof these operations, called life-cycle or cradle-to-graveanalysis, documents the inputs (water, energy, rawmaterials) and outputs (products and wastes), for thesevarious steps.
