Correct option is D
A Life Cycle Assessment (LCA) evaluates the environmental impacts associated with all stages of a product's life, from raw material extraction to final disposal. The stages typically include:
1. Raw Material Extraction (a): Harvesting or extracting materials from the environment.
2. Product Manufacturing (b): Processing raw materials into finished products.
3. Product Remanufacture (c): Refurbishing or reusing components for additional life cycles.
4. Packaging and Distribution (d): Preparing and distributing the product for consumer use.
5. Product Disposal (E): End-of-life management, including recycling, landfilling, or incineration.
Option (d) is correct as all stages mentioned fall within the scope of LCA.
Information Booster
1. Raw Material Extraction: Impacts include resource depletion and environmental damage from mining or harvesting.
2. Product Manufacturing: Includes energy consumption, emissions, and waste generation during production.
3. Product Remanufacture: Extends the product's life and minimizes resource demand.
4. Packaging and Distribution: Packaging contributes to waste, while distribution affects carbon footprint.
5. Product Disposal: Responsible disposal minimizes environmental harm; options include recycling, landfilling, or composting.
