Summary: Beer bagasse, a highly undervalued residue in the industry, with its high protein and polysaccharide content, has the potential to be used in the manufacture of bioplastics. However, its high water content requires stabilization before being considered as a raw material. This study evaluated different drying methods and found that freeze-drying was the most suitable for stabilizing the bagasse. The produced bioplastics showed appropriate properties for applications in horticulture and agriculture.

Summary: This paper reviews the current progress of recycling and reuse of waste silk, which is a result of the improvements in living standards and the throw away culture of mankind. The utilization of waste silk in various applications, such as energy, fabric, composites, skincare, biological tissue engineering, filtration, and electronics, is explored. The modification, optimization, and application of regenerated silk fibroin extracted from waste silk show great potential for industrialization and sustainable development. Furthermore, making waste silk functional and intelligently wearable provides two promising ways for recycling waste silk with low cost and high return value. The recovery and utilization of waste silk serve as a paradigm for valorization of other fiber-based waste materials.

Summary: The study found that PHA plastics with high biodegradability perform well in relation to climate tipping points but may not be the best choice for radiative forcing increase or global temperature change. Sugar beet molasses used as feedstock is a significant environmental hotspot, and increasing PHA production scale from pilot to commercial scale can increase environmental impacts due to decreasing yield. Further process optimization is necessary for PHA-based plastics to become attractive alternatives to fossil-based plastics.

Summary: The issue of fisheries waste has been increasing globally due to various factors. The utilization of these waste materials as raw materials has been proven to be effective in addressing the crisis faced by the oceans and improving marine resource management. However, the implementation of valorization strategies at the industrial level has been slow, particularly in the case of chitosan extracted from shellfish waste. To overcome this, a sustainable and circular economy approach should be adopted for chitosan valorization.

Summary: This study fills the gap in understanding the interaction between biological systems and nanoplastics by producing model nanoplastics similar to marine environments. The size, morphology, and autofluorescence of the model PET nanoplastics were characterized, and their suitability for biological studies was assessed. In vitro exposure experiments with Mytilus galloprovincialis hemolymphatic cells confirmed the internalization of the nanoplastics and their ability to emit autofluorescence. The results of this autofluorescence study provide an innovative approach for plastic risk assessment.

Summary: This study investigates the challenges associated with adsorption studies of contaminants on microplastics (MPs) in the marine environment and explores the adsorption of amoxicillin on different types of MPs. The results show that aged MPs absorb a higher antibiotic content than unaged ones due to their different specific surface areas. The thermodynamic affinity between amoxicillin and PET MPs is analyzed through Hansen's solubility parameters, and a potential interaction mechanism based on hydrogen bonding is hypothesized. Additionally, it is found that PET MPs can serve as carriers for pollutant transport in the aquatic environment.

Summary: A general method of predicting the stiffness tensor of short-fiber composites has been presented in this study, based on the fabric tensor obtained from X-ray computed tomography. The method does not rely on the specific type of fabric tensor used to characterize the symmetry properties of the composite. Experimental data from thermoplastic composite matrices reinforced with short carbon and basalt fibers were used to validate the method. The statistical alignment of fibers in each portion of the sample was measured to calculate the components of the stiffness tensor.

Summary: This paper compares the advantages and disadvantages of fused filament fabrication (FFF) and computer numerical control (CNC) milling in the specific case of conserving cultural heritage. It is found that PETG is more suitable than pine wood for reproducing the missing columns, as it retains water repellent and colorimetric properties after artificial aging. The comparison also shows that CNC milling is quicker but more expensive and produces more waste compared to FFF printing. Based on these results, FFF is assessed to be more suitable for replicating the specific column.

Summary: Polyurethane (PU) is a widely used polymer coating with favorable characteristics such as low density, nontoxicity, nonflammability, longevity, adhesion, simplicity in manufacture, flexibility, and hardness. However, it has limitations in mechanical properties, thermal and chemical stability, especially at high temperatures, where it becomes flammable and loses adhesion ability. In this study, PU composites were developed by adding reinforcements such as magnesium hydroxide and silica nanoparticles to overcome these weaknesses. The hydrophobic, physical, and mechanical properties of the pure PU and its composites were examined, and the presence of fillers was found to improve the surface topography and mechanical properties of the hybrid composite. The hybrid polymer coatings also exhibited superhydrophobic properties.
