Center for Earth Systems Engineering and Management
A collection of scholarly work published by and supporting the Center for Earth Systems Engineering and Management (CESEM) at Arizona State University.
CESEM focuses on "earth systems engineering and management," providing a basis for understanding, designing, and managing the complex integrated built/human/natural systems that increasingly characterize our planet.
Works in this collection are particularly important in linking engineering, technology, and sustainability, and are increasingly intertwined with the work of ASU's Global Institute of Sustainability (GIOS).

This paper researches an attributional life-cycle assessment (ALCA) of a commonly used consumer product, specifically one bottle of 8-ounce Aveeno Daily Moisturizing Lotion. This LCA analyzed the impacts associated from cradle-to-grave processes of one bottle of Aveeno Daily Moisturizing lotion, including raw material extraction, raw material processing, manufacturing, packaging, distribution, use and end-of-life of both the lotion itself as well as the bottle.
To successfully propose end-of-life management techniques, three different disposal options were analyzed: landfill disposal, incineration and recycling. All processes included in the system boundary were compared across three main midpoint impact categories: Fossil depletion, Freshwater depletion and Global Warming Potential. Results showed that transportation of the product outweighed all other processes in regard to the three impact categories. When all processes but transportation were considered, results showed that raw material extraction and processing was the significant contributor to the three impact categories.
This LCA therefore proposes that Aveeno take advantage of local products to limit the need for excessive transportation. Furthermore, sustainable forms of transportation could be used to offset the product’s overall environmental impacts. In regard to end-of-life disposal options, Aveeno could market recycling techniques to push forth the reuse of their plastic bottle. Considering costs, glass bottle use could also be considered to possibly implement a send-back and reuse option for consumers.
Researchers at ASU have identified opportunities to reduce risk to human health and the environment by changing the composition and disposal practices of polymers. Although plastics have benefited society in innumerable ways, the resulting omnipresence of plastics in society has led to concerns about the hazards of constant, low-level exposure and the search for options for sustainable disposal.
The team used examples from public health and medicine-sectors that have particularly benefited from polymer applications, to highlight the benefits of using plastics in certain applications and to pinpoint opportunities for reducing risks from all plastics’ uses. These include phasing out polymers that contain components associated with negative health effects, diminishing the need to dispose of large quantities of plastic through reduction and reuse, and promoting and developing less harmful alternatives to conventional plastics.
