Summary: The pyrolysis of different types of plastic waste generates distinct reaction intermediates that have different effects on the co-pyrolysis with biomass. This study investigated the co-pyrolysis of specific plastic types (PP, PS, PET, PC) and rice husk (RH) at temperatures between 600-800 degrees C. The results showed that the synergistic mechanisms in the co-pyrolysis were dependent on the plastic type. Different types of plastic had different effects on the production of aromatics, char, water, and gases during co-pyrolysis with RH.

Summary: The study investigated the kinetics of ethylene oligomerization over Ni-H-Beta catalyst at temperatures between 50 and 100 degrees C and pressures between 5 and 28 atm. The reactions showed different apparent activation energies for butene, hexene, and octene formation, with evidence suggesting that octene formation mainly proceeds via the cascade co-oligomerization of re-adsorbed butene with ethylene.

Summary: This study investigates the adsorption of ethylene on Ni-H-Beta particles to understand the roles of nickel and Bronsted sites in the catalytic oligomerization of ethylene. The results suggest the participation of two active sites in the formation of Cossee-Arlman centers and the dissociation of ethylene upon adsorption. Further characterization reveals the presence of highly dispersed Ni2+ on the catalyst surface and the interaction with lattice oxygen and free NiO crystals. The presence of residual Ni2+ and Bronsted sites hinders the formation of nickel-hydride sites and the conversion rate of ethylene. The proposed mechanism involves adsorption of ethylene on Ni2+ and a Bronsted site. This research has important implications for improving ethylene oligomerization processes over nickel-based heterogeneous catalysts.

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.
