Question
Environmental Life Cycle Assessments (LCA) LCA – First Step: Define the Goal and Scope • What is the purpose of the LCA?
Why is the assessment being conducted?
• How will the results be used, and by whom?
• What materials, processes or products will be considered?
• Do specific issues need to be addressed?
• How broadly will alternative options be defined?
• What issues or concerns will the study address?
LCA – Second Step – Inventory Analysis
• Develop an flow diagram for the processes being considered.
• Conduct an inventory analysis.
– Describe all inputs and outputs in the life cycle of a product
– Of what is the product composed?
– Where do those materials come from? Where do they go? What were the inputs/outputs related to those components?
– What about inputs and outputs during the use of the product such as electricity and batteries?
This all quantifies what comes in and what goes out (energy/material) at each stage in the life cycle
LCA: Third Step – Impact Assessment
• Identify all of the environmental impacts associated with the inputs and outputs detailed in the inventory analysis. • Group the environmental impacts around broad topics such as (use assumptions if needed):
• Wight these broad categories to yield a single score for overall environmental performance of product/process/system being analysed.
– Resource depletion
– Water use
– Global warming potential
– Ozone hole depletion
– Human toxicity
– Smog formation
– Land use
Explanation / Answer
Environmental Life cycle assessment can be defined as a essential and systematic way for the analysis of the environmental effect that is caused by a process starting from the extraction of raw materials, production, use, etc. and it is used as a tool to assess the environmental impacts of a product, process or activity throughout its life cycle.
After looking the disorders which are created in the environment, government takes a serious step to minimize the disorders. And by this action environment becomes unpolluted and clean to survive more not only got humans but for all organisms.
