“…Compared to the primary aluminum production process, aluminum recycling has a 95% reduction in electricity consumption (ŠKŮRKOVÁ;INGALDI, 2014). Recycling activities play a role in conserving natural resources and reducing pollution.…”

“…With each ton of recycled aluminum, the extraction of 4 tons of bauxite is avoided. This saves up to 95% in energy production, which corresponds to approximately 700 kg of crude oil (ŠKŮRKOVÁ; INGALDI, 2014). When mentioning the term recycling, aluminum is the rst to come to mind because it is a material that can be recycled countless times without losing its characteristics (BDEIR;ALSAFFAR, 2008).…”

“…The recycling process has one of its biggest advantages in saving energy, since it uses only 5% of the energy needed to produce the primary metal from ore (DING et al, 2012). There are also relevant environmental advantages for using recycled aluminum such as: reduction of air pollution by 95% and water by 97%, as well as a reduction of greenhouse gas emissions by 95% when compared to primary aluminum production (ŠKŮRKOVÁ;INGALDI, 2014).…”

This research presents a methodology for the recycling process via casting, in which aluminum cans and primary (commercial) aluminum are transformed into a laminated tape, with the possibility of industrial application. This research was classified as bibliographic, exploratory, and experimental, since it used qualitative techniques to evaluate alternative materials. Its objective was to incorporate materials of different properties that could favor the making of a tape to be laminated. In the first casting, a recycled aluminum ingot was formed only with aluminum from beverage cans and had a material yield of 51%. In a second casting, commercial aluminum was added to the recycled aluminum ingot. After the casting process with the two cast materials, the ingot had a yield of 90%. A third casting was conducted together with the aluminum that was already formed by the ingot (50% recycled and 50% commercial). The purpose of this ingot was to incorporate other materials that could provide some characteristics, such as malleability and conductivity. The third casting was made from the second ingot, and incorporated copper and magnesium. For the design of the laminated tape, a cast was made to receive the molten aluminum from the third casting. The aluminum was cast into this mold and three tapes were produced, one with a thickness of 2 mm, another with a thickness of 3 mm and the last with a thickness of 4 mm. With these tapes, the objective was to laminate them in order to reduce their thickness to values close to 0.5 mm. The casting process of aluminum cans with the addition of commercial aluminum, plus the incorporation of copper and magnesium, demonstrated facilities for thickness reduction in the process of making laminated tapes.
