Introducción. En Asunción existe una zona geográfica llamada Bañados, en esta zona se conforman los llamados «cinturones de pobreza», donde el trabajo informal se impone como principal medio de sustento. El oficio del reciclaje corresponde a uno de los trabajos informales más practicados. Objetivos. Describir aspectos de la zona donde desarrollan su vida trabajadora de la recolección. Incorporar elementos de resignificación positiva acerca del trabajo de reciclaje a mujeres recicladoras organizadas o no del Bañado Sur de la ciudad de Asunción, Paraguay. Material y métodos. Se realizaron 28 encuentros con 153 mujeres agrupadas en 7 grupos, durante el período del 2019 al 2022. La muestra fue seleccionada fue por conveniencia. Se eligió la modalidad de «taller» debido a las prácticas ya conocidas y aceptadas por la comunidad. Resultados. Se realizó conjuntamente la clasificación de la basura o residuos urbanos en sus categorías orgánica/inorgánica/tóxica, pero también en una clasificación más cercana a su realidad concreta. Se identificó cómo son las relaciones familiares y comunitarias, las preocupaciones por los hijos e hijas, el cambio climático, las inundaciones, las viviendas precarias, el acceso al agua, la inseguridad en el barrio y la problemática de drogas en la comunidad. Conclusión. Las jornadas se desarrollaron con mujeres recicladoras organizadas, miembros de una organización civil, que residen en el Bañado Sur – Tacumbú, Asunción (Paraguay). Durante el proceso se logró acercar a los grupos de mujeres que han podido participar de la experiencia, una resignificación positiva del trabajo y su rol en la sociedad, mediante el diálogo. Palabras clave: reciclaje, redes comunitarias, salud pública.

“…High corrosion resistance of the metal, durability and ease of use are the main advantages when using it), as well as for use in medical devices for protection against gamma radiation, in the production of X-ray and spectrographic equipment. Lead is a part of bronzes, brasses, babbits, and typographic alloys [12][13][14].…”

The article presents the analysis and results of the study of technogenic slag waste of lead-zinc production. Slags of lead-zinc production contain a large number of toxic compounds: lead, zinc, osmium, cadmium, which are dangerous sources of environmental pollution. Due to the open storage of slags, it was found that the maximum permissible concentrations of lead were exceeded. Utilization of man-made slag waste is of great importance for reducing the negative impact on the safety of life and improving the environmental situation in the region. At the same time, slags are valuable raw materials containing compounds of non-ferrous and rare-earth metals. The article shows the results of laboratory studies of slags to determine the qualitative and quantitative composition of valuable components in the waste of lead production and the possibility of their further processing and disposal. Studies of the material of the heavy slag fraction were carried out on an electron probe microanalyzer of the JEOL IXA-8230 Electron Probe microanalyzer brand. X-ray diffractometric analysis of the average slag sample was performed on a DRON-4 diffractometer with Cu radiation, graphite monochromator. Samples were selected heavy fraction and manufactured artificial polished sections (briquettes). The sections were studied under the microscope of the brand LEICA DM 2500P and immersion in liquids. According to the results of research, it was found that lead slags contain a sufficiently high amount of non-ferrous metal compounds: lead oxide up to 0.7 % and zinc oxide up to 8.5 % of the weight amount of slag, which makes the process of recycling toxic waste from lead production technically and economically feasible.

“…The technical result is the production of lead and zinc oxides. This is achieved by the fact that in the proposed technology of continuous carbon-free selective extraction of zinc and lead from the dust of electric steelmaking production, lead production slag is additionally used, fed into a rotating drum furnace by two oppositely directed flows, the dispersion of the composition containing the slag: 1-10 mm, a trifle coke and internal overburden of coal in the ratio of 1:0,2(3.8 to 4.5): from the cold end of the drum of the rotary kiln and pulverized part of the dispersion to 1 mm together with carbonaceous material dispersion up to 1 mm from the hot end of a rotary kiln, in the ratio of dust -bulk material 1: (9-9.5) and in accordance with the following scheme of the rotating drum furnace and flow chart of the method of extraction of oxides of lead and zinc are given below in figures 1 and 2 [13][14][15][16].…”

The object of the study is lead-containing slag dumps from a lead plant. The slags of the lead plant contain a large number of toxic compounds: lead, zinc, osmium, cadmium, which are dangerous sources of environmental pollution. Due to the open storage of slags, it was found that the maximum permissible concentrations of lead were exceeded. Utilization of lead production slags allows to obtain non-ferrous metals and to reduce the technogenic load on the environment as a result of processing of slags. At the same time, slags are valuable raw materials containing compounds of non-ferrous and rare-earth metals. The article proposes methods for the extraction of lead and zinc from slag waste and selects the optimal method for the selective extraction of zinc and lead oxides from dust and slags of lead production. The proposed technology of continuous carbon-free selective extraction of zinc and lead from the dust of electric steelmaking production allows the use of lead production slag, which is fed into a rotating drum furnace in two oppositely directed streams. During the movement of lead slag in the furnace drum and the burning of the torch, lead and zinc are more completely extracted from the dust-like material, where the transporting object is compressed air, and the purified flue gas after the gas is further purified by means of a smoke pump is released into the atmosphere. When using the proposed selective method for extracting non-ferrous metals, the ecological state of the environment will be improved, and it will also reduce the negative impact on human health due to the disposal of toxic slags from lead production.
