ABSTRACT
In this chapter we explore themethodology of life cycle assessment (LCA) for
use in the environmental assessment of processes and products.
LCA is a method which has been developed to provide a quantitative assessment of the environmental impact of a product over its entire life cycle. LCA accounts for both inputs and outputs, each derived from both process
and utility sources:
• inputs-consumptions of raw materials, energy, fuel and water • outputs-emissions to air, land and water.
