“…This enhances the efficiency and longevity of the biological treatment and minimizes fouling of the bioreactor, as the presence of particulate matter can impede microbial activity. Furthermore, membrane filtration also aids in preventing the release of potentially harmful by-products generated during bio-degradation into the treated water ( Rovira, 2018 ; Mackuľak et al, 2021 ; Angeles-de Paz et al, 2023 ; Noor et al, 2023 ; Sahal et al, 2023 ; Sahay et al, 2023 ). Combinatory treatment for PhAMP removal is highly versatile and adaptable to various water treatment scenarios.…”

Pharmaceuticals, recognized for their life-saving potential, have emerged as a concerning class of micropollutants in the environment. Even at minute concentrations, chronic exposure poses a significant threat to ecosystems. Various pharmaceutically active micropollutants (PhAMP), including antibiotics, analgesics, and hormones, have been detected in underground waters, surface waters, seawater, sewage treatment plants, soils, and activated sludges due to the absence of standardized regulations on pharmaceutical discharge. Prolonged exposureof hospital waste and sewage treatment facilities is linked to the presence of antibiotic-resistant bacteria. Conventional water treatment methods prove ineffective, prompting the use of alternative techniques like photolysis, reverse osmosis, UV-degradation, bio-degradation, and nano-filtration. However, commercial implementation faces challenges such as incomplete removal, toxic sludge generation, high costs, and the need for skilled personnel. Research gaps include the need to comprehensively identify and understand various types of pharmaceutically active micropollutants, investigate their long-term ecological impact, develop more sensitive monitoring techniques, and explore integrated treatment approaches. Additionally, there is a gap in understanding the socio-economic implications of pharmaceutical pollution and the efficacy of public awareness campaigns. Future research should delve into alternative strategies like phagotherapy, vaccines, and natural substance substitutes to address the escalating threat of pharmaceutical pollution.

“…In MRLSs, the need to fulfil ecological sustainability principles is justified by the hazardous effects of careless discharge of pharmaceutical products on surface waters and groundwaters [45][46][47][48][49][50]. Diverse technological solutions were proposed to curb these pollutant sources from the pharmaceutical industry's wastewater [51][52][53][54][55][56][57][58]. Nevertheless, their disposal in the environment remains poorly regulated [31], and the majority of the population is not aware of the persistence of the pharmaceutical products in water [31,33].…”

Sustainability Assessment of Medicines Reverse Logistics in Brazil: Outcomes from the National and Local Systems

Brazil adopted a national medicines reverse logistic system (MRLS) in 2020 to properly discharge medicines for human use. Parallel to this, there are Brazilian municipal MRLSs that have been working since 2002 that facilitate the appropriate discharge or reuse of medicines. These systems are not linked with each other. This paper evaluates the national and the municipal Brazilian MRLS, and compares them regarding their principles, concepts, procedures, and (socio)economic outcomes using a modified sustainability assessment framework. It was found that shared responsibility is a principle of both MRLSs, but that local systems provide additional community benefits and lead to greater circularity in the use of medicines. Procedural aspects are highly formalized only in the national MRLS. The national MRLS collected and destroyed 52.7 tons of medicines in 2021 but did not disclose the costs. Estimations based on demographic data, information disclosed by one municipality, and secondary data from five other local systems indicate that the six municipalities could return around USD 123 million in 2021 to the benefit of the local population, if they spent USD 12.6 million on correct disposal. Such an estimate, however, is not fully trackable, and it exposes the lack of transparency and data collection at the local level.

The present study investigated the use of a biosorbent produced from Leucaena leucocephala pods for the removal of metformin from aqueous solutions. The pods were subjected to chemical and thermal treatments and were referred to as L. leucocephala modified, which was characterized using scanning electron microscopy (SEM). The parameters investigated in the sorption process were temperature, contact time, adsorbent dosage, pH, and initial metformin concentration. The experimental data were in accordance with the Langmuir isothermal model. The maximum adsorption capacity reached was 56.18 mg g−1 at 313 K. In the kinetic study, stability was achieved in 300 min, with 53.24% removal, and the pseudo-first-order model agreed well with the experimental data. The thermodynamic parameters indicated a spontaneous, favorable, and exothermic reaction. The presence of NaCl, CaCl2, and MgCl2 negatively affected metformin adsorption. Thus, the importance of the study was that a developed material showed promising results in the removal of metformin, particularly because it is an innovative material, and there are no studies in the literature on drug removal using L. leucocephala.
