Question
Which of the following are the objectives of LCA study?Question 2Select one:a.Establish which of several competing products has the least environmental impact for a given product functionb.Determine which part of a product’s life cycle incurs the greatest environmental impactsc.Perform quantitative evaluation of the “cleanliness” of a processd.All of the above
Solution
d. All of the above
Explanation: Life Cycle Assessment (LCA) is a technique to assess environmental impacts associated with all the stages of a product's life from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling.
a. It helps to establish which of several competing products has the least environmental impact for a given product function. This is done by comparing the environmental impacts of different products and choosing the one with the least impact.
b. It also helps to determine which part of a product’s life cycle incurs the greatest environmental impacts. This is done by analyzing each stage of the product's life cycle and identifying the stage that causes the most harm to the environment.
c. LCA can also perform a quantitative evaluation of the “cleanliness” of a process. This is done by measuring the environmental impacts of a process and quantifying how clean or dirty it is.
Therefore, all of the above are objectives of an LCA study.
