Summary: This study investigates the transformation of triclocarban (TCC) in microbial electrolysis cell assisted anaerobic digestion (MEC-AD) reactors, and fills the knowledge gap about whether and how MEC-AD enhances the degradation of refractory pollutants in sludge. The results show that over 83.3% of TCC was dechlorinated in MEC-AD reactors, while the mass loss in the control AD reactor was only 0.53%. The presence of electrodes promoted TCC dechlorination in MEC-AD reactors, and applied voltages promoted hydrogenotrophic methanogenesis.

Summary: The increasing production of agro-industrial organic residues, particularly in the production of olive oil, poses a serious environmental concern. In this study, composting of olive pomace, olive leaves, and dewatered anaerobic sludge was conducted, and the best results were obtained with a 95:5% ratio of olive pomace to olive leaves. However, the final product did not meet the compost quality criteria in terms of E. coli levels, suggesting the need for further improvement.

Summary: The increasing use of herbal essential oils has led to rapid global production and generation of large amounts of plant residues. Co-composting herbal residues with various wastes presents an eco-friendly and cost-effective waste management option, but the biologically active compounds in these residues may impact microbial activity and compost quality. Further research is needed to assess the potential antipathogenic effects of specific herb species in composts.

Summary: The application of magnetite-nanoparticles and a microbial fuel cell (MFC) on anaerobic digestion (AD) of sewage sludge was studied. The results showed that the digester with a resistor of 500 ohm performed the best in terms of biogas production, electrochemical efficiency, voltage generation, and contaminant removal. This digester also had the highest annual energy profit. The findings suggest that the use of magnetite-nanoparticles and MFC in AD of sewage sludge holds great promise for biogas production and contaminant removal.

Summary: Bioplastics are increasingly being used as substitutes for petroleum-derived plastics due to their biodegradability, however, concerns arise over incomplete degradation and leakage into the environment during waste management processes. This paper reviews literature on the biodegradation of bioplastics in industrial and natural environments, and discusses the potential role of waste management processes in reducing bioplastics leakage.

Summary: This study compares four common methods for treating food waste: incineration, anaerobic digestion, composting, and feed processing. The results show that anaerobic digestion is the best treatment option for minimizing carbon emissions, while composting has the highest carbon emissions. In terms of economic performance, feed processing is the best choice, while incineration results in high expenditure.

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 presents a proof of concept for a technology that integrates PET recovery from mixed plastic waste and plastic pyrolysis. By depolymerizing PET into TPA using a low volatility oil as medium, it achieves low-pressure operation and a selective separation and recovery of TPA from the product mix. Full PET conversion and high TPA recovery were achieved, making it an effective solution for processing mixed waste streams and improving the yield and quality of liquid product from thermal pyrolysis compared to untreated feedstock.

Summary: This study investigated the influence of in-situ formed MgFe2O4 on the hydrothermal treatment of swine manure. The results showed that the in-situ formation of MgFe2O4 improved the dehydration and decarboxylation of organic components in swine manure, thereby improving its carbonization degree. Furthermore, it enhanced the stabilization of heavy metals and the retention of phosphorus. MgFe2O4 modified hydrochars exhibited remarkable adsorption capacity for Pb(II) and Cu(II) without any leaching of heavy metals.

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.

Summary: Incorporating biochar into composting systems can increase compost temperatures. This study developed a heat transfer model for a biochar-amended co-composting system and found that biochar increased thermal conductive losses but also enhanced microbial activity, resulting in an overall increase in total heat unit. When biochar was applied on the surface, it mainly functioned as an insulator.

Summary: The increasing demand for lightweight materials has led to a rise in fiber-reinforced plastic (FRP) production. However, the properties and compositional range of FRPs pose challenges to recycling strategies. Pyrolysis has emerged as a promising method for separating the fibers from the polymer matrix. This study investigated the pyrolysis process using thermal analysis and high-resolution mass spectrometry, and also assessed the toxicity of the recovered fibers using an in vitro model.
