“…An ideal bioadsorbent must have not only a height adsorption capacity but also the possibility to M X+ recovery from its mass. This operation involves the desorption of pollutants from bioadsorbent mass used in testing different striping agents [ 5 ]. The stripping agent is recommended so as not to damage the structure of the biomaterial and also due to a low cost of acquisitions.…”

“…Biomaterials are a valuable alternative for the retention of metal ions and other organic compounds from effluents resulting from the painting and tannery process, respectively. Recently, several papers reported the capacity of bioadsorbents to remove heavy metals and other pollutants from polluted wastewater [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. Biomaterials have been explored raw and after chemical modifications in order to enhance adsorption proprieties.…”

In this research, eco-friendly material represented by maize stalk (MS) obtained after acid treatment was employed for simultaneous removal of Cu2+, Pb2+, Ni2+, Cd2+, Cr3+ and Fe3+ (MX+) from simulated textile aqueous matrix and tannery wastewater produced by the leather industry. The acid treatment of MS was done with 4 M HCl. The influence of experimental parameters was evaluated in order to optimize the adsorption process for simulated textile matrix. The contact time 10–60 min and initial concentration of 0.5–1 mg/L MX+ influence were studied by batch method. Additionally, the adsorption data of MX+ onto MS was fitting by kinetic and isotherm models. The results obtained showed that the 60 min was necessary to reach adsorption equilibrium of the MS. The adsorption capacity of MS was 0.052 mg Cu2+/g of MS, 0.024 mg Pb2+/g of MS, 0.042 mg Ni2+/g of MS, 0.050 mg Cd2+/g of MS, 0.056 mg Fe3+/g of MS and 0.063 mg Cr3+/g of MS at pH = 4.2. The Langmuir model described the adsorption process very well. The MS showed huge selectivity for Cr3+ and Fe3+ in the presence of Cu2+, Pb2+, Ni2+ and Cd2+. The adsorption of MX+ from liquid phases were analyzed by spectrometric adsorption method (AAS). The solid phases of MS before and after adsorption by TG and SEM analysis were characterized. When MS was used for removal of MX+ from tannery wastewater, two major issues were investigated: First, the decrease of MX+ content from highly polluted and difficult to treat tannery wastewaters by improve its quality and in the second part, specific recovery of MX+ from MS mass increasing the economic efficiency of metals production based on green technology.

“…La industria alimentaria representa uno de los elementos más poderosos de la economía colombiana y mundial, demandando respuestas cada vez más complejas y exigentes (Mathew et al, 2022). La principal problemática asociada es el reciclaje de los residuos procedentes del procesamiento de las materias primas alimentarias, el cual constituye un problema económico y ecológico importante (Hussein et al, 2022).…”

La gestión de desperdicios alimentarios es un problema global, cobra cada vez mayor importancia. La generación de estos representa pérdidas económicas e impacta el ambiente y los ecosistemas, con esto, impacta directamente la salud pública y su enfoque se centra en mejorar la calidad de vida de la sociedad. El presente trabajo tiene como objetivo describir la gestión de desperdicios alimentarios desde la política pública colombiana, para lo cual se realizó un abordaje bibliográfico y una investigación de corte documental. En Colombia existe un marco jurídico que impulsa un grupo de decisiones y acciones gubernamentales o medidas públicas como el fomento del compostaje, la financiación de proyectos, la promoción de la educación en la materia, la recolección selectiva de residuos, el impulso de la economía circular y la separación de residuos. Se destaca que producto del desconocimiento generalizado de la sociedad en torno al problema, la escasa inversión y la precaria infraestructura, la ejecución de dichas políticas se vuelve cuesta arriba para el país. Se concluye que la gestión en el área requiere mayor control y seguimiento sobre la aplicación de las regulaciones, así como, el esfuerzo conjunto de gobierno, empresa y sociedad civil.

metals are frequently found in the wastewater of many industries such as mining, foundry, electroplating (coating and protective treatments), surface finishing, battery manufacturing. Other strategic elements, such as rare earth elements (REEs) [3] (or noble metals [4] ) are also discharged into the environment through industrial wastewater, also joining the food chain as they are not biodegradable. Increasingly strict legislation, together with the sustainability objectives proposed by the United Nations as well as proactive policies, make new waste recycling processes necessary to save resources and achieve sustainable development. Cadmium is mainly used in batteries (about 80% of production); another common use of this metal protective compound concerns electroplate steel (especially for aircrafts and oil platforms). Less developed application concerns the control of atomic fission in nuclear reactors (for neutron absorption). [5] Therefore, removing this metal from wastewater is of crucial importance. Along with Cd, other heavy metals such as Ni, Hg, Zn, Cu, Pb, or Cr are often found in wastewater; [1a] therefore, nickel may be another interesting tracer of metal contamination for developing alternative sorption processes. On the other hand, rare earths are extracted from their ores (after leaching step) by ion exchange and solvent extraction, which generates waste streams that are harmful to the environment. [6] Rare earths have also become strategic metals in high-tech industry; 90% of the world's extraction and production is mainly controlled by China. [7] The REE supply recently became a geostrategic and political issue worldwide for industries based on energy storage, [8] and electronic devices. [9] Cadmium and nickel are frequently associated with industrial waste (such as in rechargeable Ni-Cd batteries). On the other hand, LaNi alloys are used for hydrogen storage, they are also associated in metal hybrid batteries for hybrid cars.There are many processes to recover or remove metals from wastewater streams, such as chemical precipitation, filtration membranes or ion exchange resins, among others. [1a,3a,10] However, most of these methods are generally expensive, they are not eco-friendly, they are inefficient especially at low metal concentrations, [11] and they can also generate new residues that, in turn, need to be treated. [12] Techniques such as bioremediation [13] or biosorption [14] can take advantage of the
