Summary: Global environmental pollution from micro- and macro-plastics is a consequence of extensive use and improper waste management of conventional plastic products. Biobased and biodegradable plastics are emerging as alternatives, but the lack of advanced end-of-life technologies hinders circularity in the material economy.

Summary: The recalcitrance of modern plastics leads to the accumulation of plastics in waste management streams and the environment, making plastic waste management a key focus of research and public policy. This review summarizes the effectiveness of common approaches to plastic management, and explores recent developments in the use of naturally derived products and plastic-degrading organisms to reduce plastic waste burdens. It also discusses the potential benefits of symbiotic relationships between plastic-degrading organisms in biodegrading plastics in the environment.

Summary: 4D printing is an innovative technology that adds smart capabilities to materials so that they can respond to external stimulus, and it has immense potential in various fields of science and technology. This study investigates the feasibility of 4D printing PLA-based composite scaffolds with four different nature-inspired architectures, and the results show that the honeycomb structure exhibits the best shape memory and mechanical behavior among the four designs. The introduction of CaP enhances the mechanical strength and shape memory property, but adversely affects the surface integrity.

Summary: This study describes the development of environmentally friendly antifouling biocides based on a cyclic dipeptide scaffold. The lead compound (1) was synthesized and tested for its compatibility with a coating, efficacy against biofouling, and biodegradation. The results showed stable leaching rates under dynamic conditions but low or no leaching under static conditions. When deployed in the ocean, the coating demonstrated measurable reductions in biofouling for up to 11 weeks. Biodegradation of the compound in seawater was also evaluated. These findings provide valuable insights for the future development of commercial antifouling products.

Summary: This study investigated the impact of exposure to virtual nature on pro-environmental behavior. The first study found that participants who watched a nature video invested more effort in pro-environmental tasks compared to those who watched an urban video, although the reason behind this difference was unclear. The second study did not find a significant promotion of effortful pro-environmental behavior with nature exposure and did not replicate the nature-urban difference observed in the first study.

Summary: A protonated form of Zeolite Socony Mobil-5 (H-ZSM-5) catalyst was synthesized through a hydrothermal method using different sources of silica. The effect of loading the catalyst with yttrium, samarium, and gadolinium on the acidic properties was investigated. Among the metal-loaded catalysts, the Sm/LHZ catalyst showed the best performance in the methanol to propylene conversion due to its high amount of weak and intermediate acid sites, while the Gd-LHZ catalyst increased the selectivity towards ethane and propane.

Summary: This study investigated a novel kinetic model for the adsorption and photocatalytic degradation of methyl orange using commercial ZnO and reduced ZnO photocatalysts. The results provided new insights into the interaction of catalysts with molecules of different charges and compared with a previous study on methylene blue. The presence of oxygen vacancies in ZnO and their effects on adsorption and photocatalytic degradation were analyzed, and the photocatalytic degradation rate of reduced ZnO was found to increase significantly.
