The basic data on the volume of the formation of household (municipal) metal-containing waste, in particular, aluminum cans for drinks, cans, waste electrical and electronic equipment, electrical power sources (batteries and galvanic cells), as well as lighting lamps. The main methods of handling the indicated waste are considered and their critical analysis is presented. Particular attention is paid to the recycling and disposal of common waste such as waste electrical and electronic equipment, chemical sources of electrical current, and lighting lamps. Taking into account the rapid growth in the consumption of electrical and electronic products, it is shown that now there is a tendency not so much to improve the methods of disposal of the corresponding waste, but to ensure the production of more durable goods that provide for the possibility of their repair. A gradual transition from the 3R strategy (Reuse, Reduce, Recycle) to the 10R strategy (Refuse, Rethink, Reconsider, Reuse, Repair, Refurbish, Remanufacture, Repurpose, Recycle, Recover) is proposed. At the same time, the development of effective technologies for extracting not only traditional iron, aluminum, copper and their alloys from metal-containing household waste is not removed from the agenda, but also more scarce metals, including rare earth and heavy metals, as well as platinum group metals, which will allow significantly reduce the man-made load on the environment.

“…Prieto et al [42] presented a comparison of the stress-strain curves for aluminium foams obtained from the recycling of cans for beverages and pure aluminium, where the alloying elements such as Fe, Mn, and Mg form intermetallic compounds in the pore wall. The foam obtained from recycling presents a higher resistance than does the pure aluminium foam, an effect which is attributed to the presence of alloying elements such as Ca, Ti, Fe, and Mg which form intermetallic compounds such as Al 4 Ca, Al 3 Ti, and Al 6 (Fe, Mn).…”

This paper presents and discusses a methodology implemented to study the process of the preparation of aluminium alloy foams using the alloy A-242, beginning from the recycling of secondary aluminium obtained from beverage cans. The foams are prepared by a melting process by adding 0.50 wt.% calcium to the A-242 aluminium alloy with the aim to change its viscosity in the molten state. To obtain the foam, titanium hydride is added in different concentrations (0.50 wt.%, 0.75 wt.%, and 1.00 wt.%) and at different temperatures (923, 948 K, and 973 K) while the foaming time is kept constant at 30 s. For a set of experimental parameter values, aluminium alloy foams with the average relative density of 0.12 were obtained and had an 88.22% average porosity. In this way, it is possible to state that the preparation of aluminium alloy foams A-242 processed from the recycling of cans is possible, with characteristics and properties similar to those obtained using commercial-purity metals.
