Summary: Burning surplus agricultural residues is a common practice worldwide, but it leads to emissions and nutrient loss. Constructed wetlands can be a sustainable solution by using these residues as substrates for growing ornamental plants and generating income. This study explored the use of agricultural residues and biochar as substrates in constructed wetlands for growing ornamental plants.

Summary: The use of constructed wetlands (CWs) for wastewater treatment has attracted considerable attention worldwide. One innovative approach is the use of ornamental flowering plants (OFP) in CWs, which not only enhances the aesthetics of the system but also allows for the production of commercial flowers. This study identified the main OFP used in CWs, their phytoremediation effects, and the countries involved in this research.

Summary: Energy production in constructed wetlands, specifically vertical partially saturated constructed wetlands (VPS-CWs), can enhance the growth of evaluated plant species and efficiently remove pollutants. The generation of bioelectricity with the use of domestic wastewater as a substrate improves plant development and stimulates the growth and germination of new shoots. Different removal efficiencies were observed between systems planted with different plant species, with Canna hybrids showing better results in terms of TKN and P-PO4 removal.

Summary: The fluctuation in the number of people in tourist areas affects the wastewater quality and quantity. Constructed wetlands (CWs) aim to simulate natural processes for wastewater treatment and are considered a sustainable system. This study evaluated the effectiveness of in-vessel CWs for supporting wastewater treatment plants during periods of overloading. The results showed promising efficiency of CWs as pre-treatment to reduce overloading.

Summary: This study investigated the characteristics of constructed wetlands (CWs) in treating wastewater containing graphene oxide (GO). It was found that CWs with low water level had higher chlorophyll content in plants, lower activities of antioxidant enzymes, and enriched microbial communities. CWs were effective in removing GO, with higher removal efficiency in high water level CWs.

Summary: Constructed wetlands (CWs) are engineered systems that utilize natural processes for wastewater treatment. CWs take advantage of processes found in natural wetlands, but operate in a more controlled environment. They can be classified based on the presence/absence of wastewater on the wetland surface, and the direction of subsurface flow. Hybrid CWs combine different types of CW technologies. The use of CWs for wastewater treatment gained popularity in the 1990s and early 2000s due to stricter regulations and the application of CWs in circular economy concepts.

Summary: There is concern that the use and misuse of antibiotics can lead to an increase in antibiotic resistant genes (ARGs) in wastewater. Conventional wastewater treatment plants can release ARGs and antibiotic resistant bacteria (ARB) into natural water bodies. Constructed wetlands (CWs) offer a low-cost solution for wastewater treatment and have the potential to remove nutrients, pathogens, and ARB/ARGs.

Summary: This study investigated the factors affecting N2O emissions from constructed wetlands and developed a statistical formula to estimate N2O emission factors (EFs). The application of the formula to Greek settlements predicted a significant reduction in N2O emissions if constructed wetlands were used instead of conventional wastewater treatment plants.

Summary: Constructed or treatment wetlands are a sustainable option for wastewater treatment. This study reviewed and analyzed the use of wetlands in Mexico, including types, sizes, pollutant removal efficiency, and plant species used. Most wetlands in Mexico are subsurface flow type, with horizontal flow direction being the most common. Pollutant removal rates varied for different pollutants, with COD, BOD5, TN, and TP removal ranging from 50-90%, 60-90%, 30-90%, and 30-70% respectively. The most used vegetation in Mexican wetlands includes Typha, Cyperus, and ornamental flowering plants. The study suggests further implementation of wetlands in rural and urban regions with similar characteristics to Mexico.

Summary: In this research, an experimental plan was developed to obtain specific concrete variables and serve as a reference for a numerical and computational model. The experimental work reproduced a specific gradation of concrete, while the computational model used finite elements to simulate the behavior of concrete. The results showed that the compressive stress was more sensitive than the modulus of elasticity to changes in mesh size.

Summary: Increased temperature due to global climate change is increasing the vulnerability of billboard structures to extreme winds. This paper presents a methodology to assess the structural safety of outdoor single-post billboards. Computational fluid dynamics (CFD) modeling was used to analyze the wind forces on a flexible single-post billboard. The resulting forces were then applied to a mechanical numerical model of the billboard, and the internal forces at the most vulnerable points were evaluated. Reliability analysis showed that billboards designed for a wind speed of 180 km/h cannot meet the target safety index of 3.2 for wind speeds equal to or greater than 200 km/h, indicating potential safety risks with changes in wind characteristics.

Summary: A common problem in geotechnics is the inadequate physical-mechanical properties of soils for construction work. Traditional methods of improvement often involve using binders such as cement and lime. However, due to climate change and the need for sustainability, researchers are now exploring the use of recycled and waste materials for soil reinforcement. Natural fibers, such as sawdust, have been found to enhance the shearing strength and bearing capacity of soils by generating high friction between the fibers and the soil matrix. This concept is inspired by the natural phenomenon of grass and plants stabilizing slopes.
