Summary: The research assesses the geochemical anomalies of heavy elements and rare earth elements in soils and surface waters near a controlled municipal landfill near Madrid. The accumulation of heavy and rare earth elements in soil is attributed to wind and rain transport, while their accumulation in sediments is attributed to water transport through creeks. The surface waters show large contamination and the water quality is below allowable concentrations for drinking water. The comprehensive evaluation of the soil and water samples may be applicable to similar landfill areas worldwide.

Summary: This study investigated the environmental risk assessment and factors influencing heavy metals in the soil at municipal solid waste landfill sites through literature review, field survey, and statistical methods. The results indicated that the dominant contamination in the soil was caused by chromium and zinc, with more significant contamination found in non-sanitary landfill sites. Arsenic and cadmium were found to potentially have carcinogenic health effects. There were correlations between the concentrations of certain heavy metals and factors such as landfill age and rainfall. Proper site selection, protective systems, standardized management, and ongoing monitoring are necessary for effective prevention of ecological risks.

Summary: The study showed that early addition of liquid waste did not stimulate anaerobic decomposition of fresh MSW, and most liquid wastes were not suitable as the sole moisture source for bioreactor landfills. MSW reactors co-disposed with sludge produced more methane, while reactors co-disposed with gypsum board or foundry waste also generated methane, despite inhibitory effects indicated by biochemical methane potential (BMP) results.

Summary: This study proposes a combined process of reduction roasting of herb-medicine residue and oxalic acid leaching to improve the recovery efficiency of lithium from spent lithium-ion batteries. By utilizing the reducing gas produced from the pyrolysis of herb-medicine residue, the layered structure of the cathode powder is destroyed and converted into Li2CO3, Ni, Co, and MnO. Additionally, selective extraction of lithium is achieved using oxalic acid, and the efficiency and kinetics of lithium extraction are improved under the combined action of herb-medicine residue and oxalic acid.

Summary: This study developed and implemented a self-assessment tool to assist companies in decision-making processes for establishing circular flows based on Lean Manufacturing and Circular Economy principles. The tool utilized a maturity model and was applied to nine companies of varying characteristics. The findings revealed that certain companies showed higher maturity in water-waste and chemical-emissions management, with larger enterprises focusing on these strategies. However, many companies lacked sufficient training and employee awareness prior to seeking cleaner alternatives, and comprehensive actions to manage the product lifecycle were lacking. To address these gaps, the tool provided tailored recommendations for each company to improve their processes, products, and value chain.

Summary: The development of controlled-release fertilizer formulation is important for preventing environmental pollution caused by nutrient leaching and volatilization. This study combined biochar-based fertilizer with encapsulation technology to improve the nutrient release mechanism. Optimal conditions for synthesizing urea-impregnated biochar (UIB) were determined using central composite design, and the release of nitrogen was described by mathematical models. Results showed that encapsulated UIB (EUIB) achieved complete release of nitrogen in water and exhibited improved water retention in sandy-textural soil. Therefore, EUIB derived from peppercorn waste has the potential to be used as a sustainable controlled-release fertilizer for agriculture.
