Summary: Rice agriculture plays a crucial role in feeding over half the world's population and paddy soils greatly impact the carbon cycle. This study explores the effects of different rice husk amendments on soil organic carbon levels, greenhouse gas emissions, and dissolved organic matter chemistry. The findings suggest that flooding and amendments of rice husk and biochar promote carbon storage in rice paddy soils, despite an increase in methane emissions. Water management has a stronger impact on dissolved organic matter chemistry than amendments. However, further investigation is needed in this area.

Summary: This study investigated the potential of maximizing bioenergy recovery from rice husk using an integrated biorefinery approach, while assessing its role in offsetting current transportation and wood fuel demand in Ghana. The Oti region and Volta region in Ghana have the capacity to completely offset gasoline and charcoal demand by utilizing rice husk under ethanol and charcoal replacement policies. Liquid Hot Water and Steam Explosion pretreatments were found to be most favorable for achieving higher bioethanol and briquette yields.

Summary: The production of activated carbon from lignocellulosic biomass using chemical activation is a globally recognized method with scalability, economic viability, and environmental benefits. Chemical activation offers advantages such as energy efficiency, shorter carbonization time, and lower temperature requirements. This study employed potassium hydroxide for chemical activation, resulting in activated carbon with a high specific surface area. The activated carbon derived from rice husk was analyzed using X-ray diffraction, and its potential applications in heavy metal removal, organic pollutant elimination, and hybrid energy storage devices were explored.

Summary: This paper proposes a tracking-regulation-tracking temperature control system for batch pretreatments of LCB heated by an electrical jacket heater. The accuracy of the control system in tracking the temperature set point trajectory is measured with the weighted integral of the absolute error (SIC). The system was tested in an ethyl lactate-based 190 ℃, 1 L batch organosolv pretreatment with a maximum heating rate of 8.6 ℃/ min and a mean cooling rate of -2.4 ℃/min, and the process performance was 2.8% for an (SIC) of 1044 ℃/ min, thus confirming the efficacy of the proposed control system.

Summary: This study developed a material for stabilizing hazardous organic compounds in contaminated sediment. Activated biochar (RH-NaOH) synthesized from rice husk showed good sorption efficiency for polycyclic aromatic hydrocarbons and phthalate esters. The presence of dissolved organic matter enhanced the sorption of these compounds to RH-NaOH. The stabilization efficiency reached 96.5% and 94.6% for polycyclic aromatic hydrocarbons and phthalate esters, respectively.

Summary: This study aimed to assess the compliance of an organic compost produced from a large-scale composting process with Brazilian regulations for agricultural use. The compost, consisting of food residue mixed with tree pruning, was evaluated at a composting facility in Belo Horizonte, Brazil. The results showed that the compost batches analyzed met the standards for organic carbon and pH, but had challenges in meeting the limits for Escherichia coli, moisture, and OC/N ratio. The lack of standardization in residue proportions, difficulties in operational control, and inadequate sanitary control were identified as reasons for non-compliance.

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: 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.
