Solid waste Management: There are two articles in this section. Shi et al. (2021) investigated the unbalanced status and multidimensional influences of municipal solid waste management in Africa. It was identified that economic growth, urbanization and geographical location are the most critical factors influencing the unbalanced statue of MSW management in Africa.

Dust emissions from open-pit mining pose a significant threat to environmental safety and human health. Currently, the range of dust suppressants used in coal mining is limited, often failing to account for their suitability across various stockpiles. This oversight results in poor infiltration after application, leading to insufficient crust formation and reduced durability.

This research highlights a sustainable approach for the design and synthesis of a magnetic nickel ferrite (NiFeO) catalyst reutilizing industrial waste, specifically iron ore tailing and Raney nickel catalyst processing waste, by simple co-precipitation method. Transforming waste materials into high-performance catalysts, this study aligns with the principles of a circular economy, addressing both environmental waste and pollution. Structural characterization by X-ray diffraction (XRD) and microscopic (FESEM and TEM) revealed the formation of well crystalline nano ferrite with NiFeO nanoparticles with cubic spinel structure.

Background And Aims: There is growing interest in the environmental impact of surgical procedures, yet more information is needed specifically regarding liver transplantation. This study aims to quantify the total greenhouse gas emissions, or carbon footprint, associated with adult whole-size liver transplantation from donors after brain death, including the relevant back-table graft preparation.
Methods: The carbon footprint was calculated retrospectively using a bottom-up approach.

The study investigated the chlorine and fluorine contents in three types of industrial solid waste: textile, plastic, and paper waste, utilizing various analytical methods. Significant variations in the proportions of organic and inorganic chlorine were observed among the waste types. During heat treatment, the majority of chlorine converts to a volatile state, with fixed chlorine content showing a correlation with organic chlorine.

Basaltic glass was prepared via the solid-state melt method, using Ce to simulate tetravalent actinides. The structure, thermal stability and leaching characteristics of basaltic glass with different contents of CeO were investigated. The XRD/SEM-EDX/Raman results showed that the simulated waste loading of CeO in basaltic glass reached ~ 18 wt%, and CeO crystals precipitated when the CeO content reached 20 wt%.
