Life Cycle Impact

So far, there are major weaknesses in applying existing life cycle impact assessment characterization models to metals and more specifically to Aluminum-based products, which can lead to biased estimates of damage. To estimate the damage of polycyclic aromatic hydrocarbons (PAHs) in aluminum production sites, this study applies a life cycle assessment for pre-training electrolytic aluminum production in China. Results showed approximately 46% impact of the "average PAHs" was overestimated than existing life cycle impact assessment model (Impact2002+). Results also demonstrated the feasibility and the potential significance of including worker exposure to PAHs. Recommendations are presented to consider and compare both indoor (worker exposure) and outdoor emission of PAHs, differentiating the impact between various PAHs. These improvements are crucial for the future development of impact assessment methods that lead to comparable results between organic and inorganic substances.

(1) Background: The importance of Zinc in today’s world can hardly be exaggerated—from anticorrosion properties, to its durability, aesthetic, and even medicinal uses—zinc is ever-present in our daily lives ever since its discovery in ancient times. The natural, essential, durable, and recyclable features of zinc make it a prized material with uses in many applications across a wide array of fields. The purpose of this study was to compare two life cycle impact assessments of zinc production by using two different main raw materials: (A) zinc concentrates (sulfide ore) and (B) Waelz oxides (obtained through recycling existing imperial smelting process furnace slags). The Waelz oxide scenario was based on a case study regarding the existing slag deposit located in Copsa Mica town, Sibiu county, Romania. (2) Methods: consequential life cycle impact assessment methods were applied to each built system, with real process data obtained from the case study enterprise. (3) Results: Overall, the use of slags in the Waelz kiln to produce zinc oxides for use in the production of zinc metal is beneficial to the environment in some areas (acidification, water, and terrestrial eutrophication), whereas in other areas it has a slightly larger impact (climate change, photochemical ozone formation, and ozone depletion). (4) Conclusions: The use of slags (considered a waste) is encouraged to produce zinc metal, where available. The results are not absolute, suggesting the further need for fine-tuning the input data and other process parameters.
