Reference from the Book: Materials and the Environment $($Appendix B$)($VERY IMPORTANT$)$

Objective: The purpose of this homework is to assess the environmental impacts of a $330-$ml single$-$use PET

water bottle consumed in Dubai. You will perform a simplified Lifecycle Assessment $($LCA$)$ to evaluate

carbon emissions across its lifecycle and recommend strategies to enhance sustainable value.

Scenario: A popular bottled water brand, DxbPure, is widely consumed in Dubai. It is sold in $330-$ml virgin

PET bottles with virgin High$-$Density Polyethylene $($PE$)$ caps. Each empty bottle weighs $18$ g $,$ and its cap

weighs $1$ g $.$ The bottles and caps are molded and filled with water sourced from the pristine springs of Hatta,

UAE. After bottling, they are transported $150$ km to Dubai by a four$-$axle $(32-$tonne$)$ truck. Once in Dubai,

the bottles are refrigerated for $4$ days before being served in caf$$s across the city, significantly contributing

to the overall environmental impact. The bottles are cooled from a temperature of $30^($@$)$C to $4^($@$)$C and assume

that they occupy a space of $7$cmxx$7$cmxx$30$cm in the fridge. With no structured environmental policies in

place, the empty bottles are often sent to waste disposal sites for incineration. For this analysis, assume the

power plant efficiency is $50\%,$ and clearly specify any additional assumptions made.

Assignment Instructions:

a$)$ Streamlined LCA Analysis & Uncaptured Value:

Calculate the carbon footprint of DxbPure water across the material, manufacturing, transport,

use, and disposal phases. Provide detailed calculations in your report, create a chart to visually

display the results.

Evaluate the same product using a streamlined LCA matrix. Make necessary assumptions and

include a brief analysis of how this method differs from the detailed calculations.

Based on your analysis of DxbPure water bottles, identify instances of value uncaptured $($e$.$g$.,$

value surplus, missed, absence$,$ or destroyed$)$ across its lifecycle phases. Furthermore, propose

specific strategies to recover this value and improve the bottle's sustainability and overall

lifecycle performance.

Write a $3-5$ page report summarizing the analysis described above.
