Summary: Studies on biogas production from different organic materials in anaerobic conditions are conducted worldwide, with key parameters including raw material potential, production processes, economic analysis, and environmental impacts. Chicken manure is a significant raw material in biogas production, with research showing the potential for producing 8.58 million m(3) of biogas annually from processing about 110,000 tons of waste. This process also generates 17 GWh/year of electricity, 16 GWh/year of thermal energy, and reduces CO2 emissions by 13.86 thousand tons/year.

Summary: Management of chicken manure in Morocco has become a focus due to the increasing demand for chicken and eggs. The bioconversion of chicken manure into biogas can reduce the amount of manure while generating clean energy. Comparing with co-firing, pyrolysis, and gasification, anaerobic digestion of chicken manure was found to be superior in terms of energy gain.

Summary: Anaerobic digestion is a well-known method for stabilizing organic materials, offering benefits such as greenhouse gas reduction, alternative energy production, and valuable digestate acquisition. However, for heterogeneous materials like manure, single-substrate digestion may not be efficient. Co-digestion studies are increasingly appearing to address this issue, allowing higher biogas production and simultaneous waste processing. The future effective application of anaerobic co-digestion depends on regulations, work regime, and access to raw materials, which are explored in this paper.

Summary: In India, rural areas account for only 23% of national electricity usage, highlighting the need to expand access to electricity for sustainable development. Biomass, particularly in the form of biogas produced from organic waste, provides a simple and direct energy source for cooking, heating, and electricity generation in rural households. Biogas production offers a pathway to generate electricity in villages through technologies like Solid Oxide Fuel Cells, ultimately bringing power closer to rural communities.

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 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: 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.
