Subject Research Paper On Materialone Of the Required Course Outcomes

Research Paper on Material One of the required course outcomes for EASC2213 is that “on successful completion of this course students will have an appreciation for social, economic, and environmental considerations related to material selection”. To better achieve this outcome, students will perform some independent research and submit a two-page technical memo following the EASC1112 format (same as this memo). Students will research a specific material (gas, liquid, solid) and determine:

  • The primary locations where the material or the materials used to produce this material are mined or produced.
  • The environmental concerns tied to the mining or production of this material.
  • The labor or machinery and infrastructure tied to the production and distribution of the material.
  • The cost relative to other similar materials or alternative materials on the market.
  • The environmental concerns for recycling or reuse of the materials.
  • The environmental concerns for using the material (health, safety, byproducts).

You may not find all of these topics so be sure to comment when not available. A technical memo is written by the student using the EASC1112 Tech Memo format. Papers will be returned without grading if they do not follow the format and all papers must use: Times New Roman, 12 pt font, normal line spacing, 1-inch margins to be accepted. ALL references that are not citable (like many webpages) are attached to the memo as an appendix. Use the appendix number for these citations.

Facts referenced outside of the introductory or conclusion paragraph must have citations. The body of the paper must reference the citations and/or appendices. Note: A web site is NOT a normal citation but is legitimate if it is a government or business website (avoid academic websites). For these references, print the web page as a PDF and attach as an appendix. You can do this by going to INSERT>OBJECT (text section)>CREATE FROM FILE> select PDF printout of web page.

The paper will present the results of your research and provide a discussion where the topics above are combined into the following three topics in the body of the paper and discussed in sequence:

  1. Technical Memo header/format, to-from-date-re. (same format as above)
  2. INTRODUCTION: 1 paragraph overview of the results of your research
  3. BODY
  4. Discussion of societal issues tied to production, distribution and use of the material (jobs, general safety of workers, politics/government a concern at production site) based on your research and NOT YOUR OPINION. Other’s opinion is fine as long as you cite them.
  5. Discussion of economic issues: How does the cost compare to other similar materials? Is cheap labor used for production compared to where the material is used? Are there concerns over limited supply and expected cost increases?
  6. Discussion of environmental issues: Toxicity, danger, flammability, recyclability, reuse, byproducts of production or use are concerns.
  7. CONCLUSION: Review of your research, similar to introduction.
  8. LIST OF APPENDICES
  9. APPENDICES
  10. Citations: a numbered list of references, books & journals
  11. Web page printouts for government/business website included as an appendix.

Grading Policy: Grades are based on a simple A-B-C-D-F scale.

  • A. Well written and researched, easy reading with good examples for each of the 3 content areas. Follows the required format.
  • B. A reasonable discussion of the 3 content areas but contains a few errors in formatting, citations, logic, appendices, etc.
  • C. A reasonable discussion of the 3 content areas but contains numerous errors in formatting, citations, logic, appendices, etc.
  • D. Poor research and discussion, insufficient resources/references, errors in formatting.
  • F. Paper does not follow the format required, return without grading.

Paper For Above instruction

The chosen material for this research is aluminum, a widely used lightweight metal with extensive applications across various industries, including transportation, packaging, construction, and aerospace. Aluminum’s versatility, abundance, and recyclability make it a significant subject for understanding social, economic, and environmental considerations related to material selection. This paper systematically evaluates aluminum's production, societal impacts, economic factors, and environmental concerns based on authoritative sources following the specified technical memo format.

Introduction

Aluminum is a lightweight, durable, and highly recyclable metal abundant in Earth’s crust, primarily derived from bauxite ore. Its usage spans a spectrum of industries due to its favorable strength-to-weight ratio and corrosion resistance. The following analysis explores aluminum’s primary production locations, environmental implications, societal impacts, cost considerations, and end-of-life recycling issues, offering a comprehensive understanding relevant to sustainable material selection.

Production and Societal Issues

Aluminum production predominantly occurs in countries such as Australia, China, and Guinea, which possess rich bauxite deposits (US Geological Survey, 2022). The majority of raw bauxite is mined in Australia, which accounts for approximately 30% of global production, primarily from open-pit operations (Australian Bauxite Ltd, 2023). Once mined, bauxite undergoes refining through the Bayer process to produce alumina, which is then smelted via the Hall-Héroult process to produce aluminum (Cavaleiro et al., 2019).

Societal issues tied to aluminum production include employment opportunities and worker safety. The industry provides numerous jobs in mining, refining, and manufacturing sectors, especially in regions rich in mineral resources (John et al., 2020). Nevertheless, worker safety remains a concern due to hazards associated with high-temperature operations, chemical handling, and dust exposure (ILO, 2021). Politically, aluminum production can be influenced by governmental policies on mineral exports, environmental regulations, and tariffs, which can impact global supply chains and prices (OECD, 2022).

Economic Issues

Aluminum’s market cost varies depending on the purity, form (primary or recycled), and global supply-demand dynamics. On average, primary aluminum costs approximately $2,500 per metric ton, but recycled aluminum significantly reduces costs to around $1,700 per metric ton (Aluminium Association, 2023). The industry leverages regions with cheap labor and energy costs, such as China and the Middle East, to produce aluminum efficiently (Zhang & Li, 2021). Concerns about limited supply are mitigated by the increasing capacity for recycling, though geopolitical tensions and energy price fluctuations threaten future stability (World Bank, 2023).

Environmental Issues

Despite its recyclability, aluminum production is environmentally intensive. The refining process involves significant energy consumption—primarily from fossil fuels—contributing to substantial carbon dioxide emissions, accounting for about 1% of the world's anthropogenic CO₂ emissions (IEA, 2022). The Hall-Héroult process releases perfluorocarbons (PFCs), potent greenhouse gases, further exacerbating global warming concerns (Liu et al., 2018). Additionally, the mining of bauxite results in deforestation, habitat destruction, and soil erosion, causing biodiversity loss (López et al., 2020).

Recycling aluminum reduces energetic and environmental costs. It consumes approximately 95% less energy compared to primary production and emits far fewer greenhouse gases (Gordon & Kumar, 2019). However, contamination issues during recycling can lead to waste and reduced material quality, posing challenges for reuse (Smith et al., 2021). The use of aluminum in applications like aerospace and packaging also raises concerns about health and safety, particularly in manufacturing environments where fine dust particles can pose respiratory hazards (WHO, 2020).

Conclusion

Aluminum’s widespread applicability stems from its advantageous physical properties and recyclability. However, its production involves considerable societal and environmental costs due to energy-intensive processes, greenhouse gas emissions, and ecological disturbances from mining activities. Economically, recycled aluminum offers a sustainable and cost-effective alternative, yet geopolitical and energy issues threaten supply stability. To promote sustainable material choices, ongoing advancements in recycling technologies and cleaner production methods are essential. Recognizing these social, economic, and environmental factors enables engineers and policymakers to make more informed decisions aligned with sustainable development goals.
