Summary: This study evaluated the phenol and lignin removal and enzyme activity in the biological pre-treatment of olive mill solid waste (OMSW) using Anthracophyllum discolor and aquaculture sludge (AS) as an external nitrogen source. The highest removal of lignin and enzymatic activity was achieved in the mixture of OMSW and AS with a C/N ratio of 45. The pre-treatment under these conditions removed 66% of lignin and 68% of phenols in the solid phase, 56% of phenols in the liquid phase, with maximum activities of laccase, manganese peroxidase, and manganese independent peroxidase recorded in 25, 30, and 15 days of pre-treatment, respectively. These findings suggest that incorporating AS as a co-substrate to adjust the C/N ratio allows for increased lignin removal and manganese peroxidase activity, facilitating the treatment of OMSW and AS wastes and the potential recovery of valuable enzymatic extracts.

Summary: This study investigated the effects of different eastern oyster culture methods on the abundance of Vibrio vulnificus and V. parahaemolyticus. The results showed that on-bottom cultured oysters had higher abundances of total and pathogenic V. parahaemolyticus, while off-bottom cultured oysters in a subtidal location had higher abundances of V. vulnificus. Temperature and salinity were positively correlated with Vibrio spp. concentrations, while turbidity had a negative effect. There was no observed relationship between chlorophyll and Vibrio spp. abundances.

Summary: Polyhydroxyalkanoates (PHAs) are biodegradable natural polymers that are considered an emerging alternative to petroleum-based plastics. Aquaculture has shown potential for PHA production, but challenges remain in commercializing these polymers. Combining PHA production with biofloc technology can potentially improve production efficiency in aquafarms.

Summary: This study established a computational fluid dynamic model coupled with a discrete phase erosion model to reveal the gas-solid jet flow and erosion wear characteristics in the bottom injecting lance. The results showed that adding powder into the gas had a significant influence on the pressure and velocity of the gas in the lance, while the lance structure also affected the jet flow and erosion wear.

Summary: The laboratory experiments discovered that raindrops induce different modes of motion in particles of different sizes, and that the particle distribution of rain-impacted sediment discharge changes over time. The experiments also found that sediment discharge induced by raindrops peaks at a specific flow depth. The assumption that rain erosion is solely determined by flow discharge and rainfall intensity is proven to be false.

Summary: Aquaculture generates a significant amount of waste, and European legislation encourages proper management and sustainable utilization of these wastes. The application of circular bio-economy can protect human and animal health and the environment. In Galicia, aquaculture is an important industry that needs to be integrated into the circular bio-economy for improved production efficiency.

Summary: Bottom trawling has been extending to deeper ocean areas since the mid-XXth century, causing depletion of organic carbon in sediment and degradation of labile compounds. Temporary trawling closures aimed at protecting fish stocks have limited effectiveness in restoring the seafloor, with potential long-term biogeochemical impacts at a global scale.

Summary: Aquaculture is a rapidly growing industry, and Integrated Multi-Trophic Aquaculture (IMTA) is a potential solution to minimize waste impact on ecosystems. However, there are challenges to implementing IMTA in Atlantic Salmon farms, such as scaling up extractive species and economic issues.

Summary: The benthic impact of aquaculture waste is influenced by the accumulation and flow of waste around and below the farm. A study on an oyster aquaculture farm in the Damariscotta River found that despite slightly higher sediment erodibility at the farm compared to a downstream site, similar biogeochemical fluxes, geochemical properties, and macrofaunal communities indicated minimal impact on benthos. The study also observed microalgal mat presence and partial failure under high shear velocity, but suggested that peak bottom velocities during spring tides may periodically clear under-farm sediment of recent deposits.

Summary: The use of incineration bottom ash (IBA) from fluidised bed (FB) combustion technology as a precursor for alkali-activated binders (AABs) was evaluated. IBA-FB was compared with IBA from moving grate (IBA-MG) combustion technology. The formulation of AABs using IBA-FB and IBA-MG was assessed from various perspectives, revealing differences in workability, consistency, porosity, and mechanical strength.

Summary: Replacing conventional fine aggregates with spent mushroom substrate (SMS) aims to develop a sustainable lightweight masonry mortar and provide an alternative solution for improper mushroom waste disposals. The study investigated the effects of incorporating 2.5-15.0% (by volume) SMS passing through a 4.75-mm sieve on various properties of the mortar. Results showed that as the SMS replacement percentage increased, the density of the SMS mortar decreased up to 34.8% and the compressive strength ranged from 24.96 to 3.37 MPa. Mixes with up to 12.5% SMS met the minimum requirements stated in the ASTM C129 standard for compressive and flexural strengths. Additionally, the use of SMS resulted in a reduction of equivalent CO2 emission by 15.09% and increased cost-effectiveness up to 98.15% until 7.5% SMS replacement.

Summary: In the hyper-tidal Minas Basin, the concentration of total suspended matter increases dramatically in winter due to remobilization of material from tidal flats and cliff erosion by storms. The particle packaging and settling varies between winter and summer, with large, low-density flocs forming rapidly in winter but small, high-density aggregates dominating in summer. Flocculation rate increases in winter, but sediment remains mobile due to high stresses. The transition from winter to summer sees rapid floc formation and settling, with material accumulating on the flats in summer.

Summary: The study examines the impacts of powerful storms and storm surge on coastal areas, particularly in the Gulf of Maine and Bay of Fundy system. Using a coupled hydrodynamic-wave model, the research investigates the effects of Hurricane Arthur in 2014 and the historically significant Saxby Gale of 1869. Results suggest that a well-timed tropical cyclone during a high spring tide has the potential to cause extensive flooding by overtopping existing dyke systems.
