Life Cycle Assessment (LCA) Quiz

Life Cycle Assessment (LCA)

Definition Life Cycle Assessment (LCA) is a method used to evaluate the environmental impacts of a product, process, or service throughout its entire life cycle, from raw material extraction and processing, to manufacturing, distribution, use, and disposal or recycling.

Phases of LCA

1. Goal and Scope Definition: Define the study's purpose, boundaries, and functional unit.
2. Inventory Analysis: Collect and quantify the inputs (e.g., energy, materials) and outputs (e.g., emissions, waste) of the product or process.
3. Impact Assessment: Evaluate the potential environmental impacts of the product or process, such as climate change, resource depletion, and human health effects.
4. Interpretation: Analyze and discuss the results, identifying areas for improvement and opportunities for environmental impact reduction.

Life Cycle Stages

1. Raw Material Extraction: Extraction of raw materials, such as mining or harvesting.
2. Manufacturing: Production of the product, including processing and assembly.
3. Distribution: Transportation of the product to the consumer.
4. Use: Consumer use of the product, including energy consumption and maintenance.
5. End-of-Life: Disposal, recycling, or reuse of the product at the end of its life cycle.

Benefits of LCA

• Identifies areas for environmental improvement
• Supports sustainable decision-making
• Enhances product design and development
• Facilitates comparison of environmental performance between products or processes
• Helps to reduce environmental impacts and costs
