Summary: The co-pyrolysis of date palm and cashew shell wastes was studied, revealing their physicochemical properties, synergistic interaction, and thermal degradation behavior. The study estimated kinetic and thermodynamic parameters using thermogravimetric analysis and found that co-pyrolysis lowered the activation energy and produced stable biochar. The research is important for advancing the utilization of these underutilized wastes and optimizing the pyrolysis process.

Summary: The effects of screw diameter, pilot hole, and material type on withdrawal load resistance of screw driven in medium density fibreboard and particleboard were investigated. The study found that material type and screw diameter had significant effects on the load resistance, while the pilot hole did not. The equations proposed in Eurocode 5 had better performance in predicting load resistance than other equations.

Summary: The gasification kinetics of pellets obtained from organic solid wastes and raw materials were studied using the Coats-Redfern and DAEM methods. The activation energies obtained by each method affirmed the accuracy of the kinetics calculation. The results showed that the activation energies of the char gasification stage were higher than those of the devolatilization stage, and the activation energies of the pellets were higher than those of the corresponding raw materials in the devolatilization stage but lower in the char gasification stage.

Summary: Pyrolytic kinetic and thermodynamic analyses of date seeds were conducted using TGA. The results showed that the pyrolysis process consists of three stages: dehydration, devolatilisation, and char formation. The kinetic evaluation was performed using the Coats-Redfern method, and the best-fit model was the Zhuravlev diffusion equation. The data obtained are valuable for understanding the pyrolysis mechanism of date seeds and can be used in the design of pyrolysis reactors.

Summary: This article discusses the fracture behavior of medium-density fiberboard (MDF) and particleboard (PB) under mixed mode loading conditions. By examining the elastic properties of wooden samples and applying LEFM concepts, the maximum tangential strain (MTSN) criterion is used to predict fracture initiation angles and toughness. The Weibull statistical analysis shows that the mode II test results can be well-estimated based on the value of KIf using the MTSN criterion, especially when seeking the probability of mode II fracture based on mode I statistical parameters.

Summary: The aim of this study is to investigate the thermal behavior of Pinus wood pellets during torrefaction under different operational conditions and evaluate the potential application of the torrefied product in metallurgical processes. The experimental results showed that high torrefaction temperature and residence time decreased the mass yield. The best torrefaction conditions for biomass with potential application in metallurgical processes were in an inert atmosphere, at 290 degrees C and a residence time of 15 min.

Summary: This paper aims to identify sustainable circular economy pathways for waste MDF and particleboard management through life cycle assessment, comparing landfill, recycling, and energy recovery scenarios. The results show that material recovery is preferred over energy recovery in most impact categories, except for climate change and fossil fuel depletion. The management of waste engineered woods has less impact than the production process, and energy recovery has the greatest toxicity impacts.

Summary: The study investigated the triboelectric charging of wood particles during wood cutting, finding that factors such as wood species, number of saw blade teeth, cutting direction, and wood moisture influenced the electric field strength levels and polarity of the generated wood particles. Accumulated triboelectric charging was observed in the wood particles, with the charge transfer intensity being inversely proportional to the moisture content, especially in cross-sectional cuts.

Summary: This study investigates the co-combustion characteristics of electrolytic aluminum waste and bituminous coal. The results show that both cathode carbon blocks (CCB) and hardened material (HM) can efficiently promote the ignition performance of the blends, but the burnout performance is weakened as the mass proportion of HM increases. Remarkable synergy occurs during the co-combustion process, where the changes in pre-exponential factors play a key role.

Summary: This article presents and discusses the available studies on utilization of waste wood (WW) resource for wood-based panel production. The majority of WW research was from Europe and focused on recycled material from particleboard. Particleboard was identified as the primary option for wood-based panel production using waste wood. There was a lack of research on recycling plywood. Physical and chemical contaminants varied depending on the origin of the recycled wood, and the properties of wood-based panels decreased with higher proportions of waste wood content.

Summary: The research found that the mechanical performance of particleboard decreases when BSG is added, but the impact is not critical for particleboards produced with 10% BSG, which could potentially be classified as suitable for non-load-bearing panel applications in dry conditions with good dimensional stability and stiffness.

Summary: Waste particleboards, generated from discarded furniture and building materials, can be efficiently utilized as an energy source through pyrolysis technologies. This study explores the co-pyrolysis treatment of waste particleboards and wood, and finds that blending wood with waste particleboards can improve the pyrolysis reactivity and distribution of pyrolytic compounds. The highest yield of pyrolysis products is achieved when the blending ratio of wood is 50%.

Summary: This study explored the pyrolysis behaviors and mechanisms of different monosaccharides, including arabinose, galactose, galacturonic acid, and glucuronic acid. The roles of structural differences in these monosaccharides were analyzed, and it was found that glucuronic acid undergoes a special C-C bond breaking reaction during pyrolysis. The findings provide a deep understanding of the pyrolysis chemistry of hemicellulose and the role of different branches.
