This report presents a Life Cycle Assessment (LCA) comparing paper and plastic shopping bags, utilizing GaBi software to evaluate their environmental impacts throughout their lifecycles, from raw material acquisition to disposal. The study highlights that paper bags, particularly those made from recycled materials, have a lower environmental footprint compared to plastic bags, which contribute significantly to pollution and waste. The assessment considers factors such as material usage, manufacturing processes, and end-of-life scenarios. The findings emphasize that the production of plastic bags releases more carbon emissions and that plastic waste does not biodegrade, leading to soil and environmental degradation. The report concludes by recommending the use of paper shopping bags as a more sustainable choice, supporting the 'going green' initiative, and promoting environmentally friendly practices. The second part of the report addresses energy efficiency analysis.
