Massive timber is a category of heavy green engineered products, manufactured from glued or glued-free processes, to be used in more predictable structural performance in industrialized walls, floors and frames. Massive plywood panel emerges as a novelty for mass timber construction and, therefore, little information is scientifically available. Aligning with the Sustainable Development Goal 9: ‘Industry, innovation and infrastructures’, this study aims to verify this literature gap and raise topics regarding massive plywood panels using a structured systematic review literature. From bibliometric analysis, 12 journal papers, 10 conference papers and an editorial were prospected using Scopus and Web of Science databases. A predominance of studies from English language nations was confirmed. Seismic and monotonic performance of massive plywood are frequent topics in these investigations, whose results have indicated a promising scenario for construction. As no study on industry is available, a case study on massive plywood was sequentially developed to discuss features of commercial panels and perspectives of respective global industry. The North American Freres Engineered Wood and Finnish Metsä Wood are the only active manufacturers, and their massive plywood panels have been manufactured from modern production technologies and environmentally certified practices to be applied in low- and high-rise industrialized buildings.

The aviation industry has a significant impact on the environment, accounting for 13% of global fossil fuel consumption and 2% of annual CO 2 emissions. One of the factors that increase this consumption is engine degradation due to the accumulation of dirt on compressor blades. To mitigate this effect and restore efficiency, compressor washing is essential, but it requires high water consumption. This study analyzes the operational, economic, and environmental benefits of optimizing this process, based on the Blue Economy. Fuel efficiency was assessed using the Fuel/RTM indicator, financial viability using ROI, and environmental impacts using the MIF index. The results indicate a 1.8% gain in fuel efficiency, annual savings of $179,000, a 6.9% reduction in environmental impact, and a 50% drop in water use. The findings demonstrate that sustainable maintenance practices generate economic and environmental gains, contributing to the conservation of water resources in aviation.

The dispersion of SARS-CoV-2 in aquatic environments via the discharge of domestic and hospital sewage has been confirmed in different locations. Thus, we aimed to evaluate the possible impacts of zebrafish (Danio rerio) exposure to SARS-CoV-2 peptide fragments (PSPD-2001, 2002, and 2003) alone and combined with a mix of emerging pollutants. Our data did not reveal the induction of behavioral, biometric, or mutagenic changes. But we noticed an organ-dependent biochemical response. While nitric oxide and malondialdehyde production in the brain, gills, and muscle did not differ between groups, superoxide dismutase activity was reduced in the "PSPD", "Mix", and "Mix+PSPD" groups. An increase in catalase activity and a reduction in DPPH radical scavenging activity were observed in the brains of animals exposed to the treatments. However, the "Mix+PSPD" group had a higher IBRv2 value, with NO levels (brain), the reduction of acetylcholinesterase activity (muscles), and the DPPH radical scavenging activity (brain and muscles), the most discriminant factors for this group. The principal component analysis (PCA) and hierarchical clustering analysis indicated a clear separation of the "Mix+PSPD" group from the others. Thus, we conclude that exposure to viral fragments, associated with the mix of pollutants, induced more significant toxicity in zebrafish adults than in others.
