Summary: Traditional freshwater sources have been over-abstracted, resulting in a worldwide water scarcity crisis. An investigation found that industrial wastewater samples contained high concentrations of Zn2+ and Pb2+, which are known to be highly harmful to humans and wildlife. This study used Streptomyces sp. as a biosorbent to effectively extract Zn2+ and Pb2+ from single and binary metal aqueous solutions. The biosorbent demonstrated high adsorption capacity and followed Freundlich isotherm, making it a potential alternative for removing Zn2+ and Pb2+ from aqueous solutions.

Summary: This study investigated the removal of lead from aqueous solutions using biochar derived from olive mill solid and liquid wastes. The results showed that lead adsorption by biochar is influenced by factors such as biochar dose, solution pH, and the presence of competitive ions.

Summary: Arabica-coffee and Theobroma-cocoa agroindustrial wastes were treated with NaOH to efficiently remove Pb(II) from aqueous media. The biosorbents exhibited significantly higher Pb(II) adsorption capacities compared to untreated wastes and other similar agro-industrial biosorbents. The optimal conditions for Pb(II) adsorption were found to be a pH between 4 and 5 with a biosorbent dose of 2 g center dot L-1. The adsorption process was found to be chemisorption with a monolayer mechanism.

Summary: Different plastics from solid waste were sorted and analyzed by pyrolysis. The oil yield varied among different types of plastics, with EPS > PP > PE > HIPS > PET > PVC. The composition of the produced oils differed as well, with HIPS and EPS oils being aromatic, PVC and PET oils containing a significant amount of aromatics, and PE oil rich in olefins. Methane was the dominant gas component in all pyrolysis gases, followed by ethane.

Summary: Using science mapping, we analyzed the increasing number of scientific documents on the negative environmental impacts of PPE waste, particularly face masks, used for reducing SARS-CoV-2 transmission. India, China, and Canada emerged as leaders in this research field, focusing on environmental issues and engineering solutions. Our analysis highlighted the significant negative effects of PPE waste on aquatic ecosystems, greenhouse gas emissions, and wildlife. To address these impacts, innovative ecodesign strategies for green production, reuse, and recycling, as well as collaboration with the public to reduce waste at its source, are essential. Implementing a collective, extended producer responsibility system for PPE can ensure sustainable production and consumption, contributing to the achievement of sustainable development goals.

Summary: This research aims to develop a new strategy to convert wasted COVID-19 masks into useful products through chemical recycling by pyrolysis. The results showed that pyrolysis at different temperatures yielded valuable solid (biochar), liquid (biooil), and syngas products. By using a two-stage pyrolysis catalytic reactor with sepiolite as a catalyst, the final yield of syngas product increased and the composition of biooils changed. The study also examined the effect of sepiolite regeneration on consecutive pyrolysis tests.

Summary: This contribution proposes an in-situ catalytic pyrolysis process to valorize rejected plastic wastes from mechanical-biological treatment. It focuses on producing a liquid fraction with similar properties to traditional fuels and utilizes Simulated Distillation, hydrocarbon types analysis, CHNS-O analysis, and Fourier Transform Infrared Spectroscopy for fuel fraction identification. The catalytic structures Sepiolite and Montmorillonites (K10 and K30) are employed, and their properties affecting the catalytic activity and product yields are analyzed. A comparison with hydrocarbons from the petroleum industry is provided to evaluate the technology in the current energy scenario.
