<p><i>Due to rise in income and living standards in developing world there is a substantial growth in the use of home appliances. This growth is responsible for several environmental issues.&nbsp;Hence, there is a growing demand for energy efficient, environment friendly, and sustainable appliances. This study compares the environmental impacts of three home appliances using Life Cycle Assessment (LCA). Three irons of same power rating but with different prices (low, medium, and high) were selected for this study. First, energy consumption of these irons was measured and then they were disassembled to generate a detailed list of components, materials, and processes used to manufacture them. Next, LCA was conducted using SimaPro to compare the environmental impacts of these products.&nbsp; All life cycle stages including material extraction, component manufacturing, assembly, distribution, and use were considered in LCA. Both ReCiPe mid-point and end-point environmental impacts were calculated.&nbsp;The results of this study showed that low-price iron, in general, consumed more energy and was more damaging to the environment as compared to high price iron. The high-price iron had on average 7% less environmental impacts than the low-price&nbsp;iron. The use of efficient power assembly and materials contributed to this superior environmental performance.&nbsp;</i></p>

ASME 2021 International Design Engineering Technical Conferences & Computers and Information in Engineering Conference (IDETC/CIE2021)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
