Summary: Aquaculture production is a significant part of global food supply, with recent studies suggesting that intensifying shrimp aquaculture could save resources on a per tonne basis. By analyzing production parameters such as feed type and water exchange rate, the study found that land and water use have an asymptotic relationship with production intensity, with water exchange rate being the most important factor in water use and production intensity in land use. Energy use was highest with diets containing fish meal as a protein source, indicating the potential for resource savings with increased production intensities.

Summary: The treatment of wastewater generates a large amount of water treatment sludge (WTS), but this sludge can be used as a byproduct in the construction industry to replace natural raw materials. Adding concrete waste (CW) to the blend can improve the technological properties of bricks. The study found that the addition of CW increased water absorption and apparent porosity, while decreasing bulk density, compressive strength, and thermal conductivity of the bricks.

Summary: Sustainable management of natural resources is critical to food security, particularly for the expansion of the shrimp feed and fishery sector. Microalgal biomass has the potential to serve as an environmentally friendly and nutrient-rich alternative to fish feed ingredients. Fish and microalgae have similar nutritional profiles, and highly digestible feed can reduce production costs, feed waste, and the risk of pollution.

Summary: The study evaluated the use of microalgae in remediating effluent from brown crab aquaculture. Various microalgae strains showed high removal efficiencies for nitrogen, phosphorus, and chemical oxygen demand. Among them, Chlorella vulgaris and Scenedesmus obliquus exhibited the best performance. Supplementation with NaNO3 improved nutrient removal by microalgae, with resulting biomass potentially suitable for aquaculture feeds. Additionally, the biomass of these microalgae strains showed promising potential as biostimulants for germination of wheat and watercress.

Summary: By cultivating tilapia in an air-tight tank of a recirculating aquaculture system, CO2 is produced for the growth of Scenedesmus armatus in photobioreactors. It was found that the CO2 concentrations in the tank were higher than in the atmosphere, and using the captured CO2 and nitrate from tilapia farm effluent enhanced algal biomass production. This study demonstrates the potential of repurposing CO2 from aquaculture systems to enhance algal cultivation.

Summary: Microbial polyhydroxyalkanoates (PHA) are promising biodegradable polymers that can alleviate environmental problems caused by petroleum-based plastics. However, the increasing waste removal issue and the high cost of pure feedstocks for PHA biosynthesis have led to the need for utilizing waste streams from various industries as feedstocks for PHA production. This review summarizes the state-of-the-art progress in utilizing low-cost carbon substrates, effective upstream and downstream processes, and waste stream recycling to achieve process circularity. It also discusses the use of different bioreactor systems and advanced tools and strategies to enhance productivity and reduce costs in microbial PHA biosynthesis.

Summary: Biochar produced from thermochemical processing biomass is being developed as an effective way to mitigate climate change, and its stability is crucial for its potential in climate change mitigation. There is currently no standard method available for assessing biochar stability, and results from different methods show significant differences. Research findings show that the volatile matter/(fixed carbon + volatile matter) has high correlations with other indicators, aiding in the evaluation of biochar stability.

Summary: A CSMP reactor coupled with an ex-situ catalytic bed was developed for the conversion of LLDPE to high-grade fuels. The addition of HZSM-5 catalyst led to the production of refined chemicals dominated by gasoline-range hydrocarbons. High selectivity of gasoline-range hydrocarbons was achieved at a catalyst-to-reactant ratio of 15% and feeding rate of 6 g/min. The pyrolysis processes yielded ethylene as the main gas product, while propylene and propane were the primary gas components with the addition of HZSM-5. The net energy gain increased with growing feeding rate from 6 g/min to 30 g/min.

Summary: This study found that the residue content of oil-bath co-torrefaction was the highest at 97.01%. Oil-bath co-torrefaction can maximize the retention of hydrogen atoms in corncob, which is beneficial for deoxygenation during pyrolysis. It can also reduce the average activation energy required for corncob decomposition.

Summary: A novel catalyst of lignin biochar supported Ni was prepared and showed high catalytic activity for the production of aromatic hydrocarbons from Chlorella vulgaris. The catalysts exhibited abundant functional groups, with surface areas of 290.87-458.97 m2/g and average micropore sizes of 0.47-0.56 nm. In-situ reduction during catalyst preparation resulted in the formation of Ni0 particles with an average size of 37.57 nm. The catalytic pyrolysis of microalgae and model compounds demonstrated high selectivity for benzene, toluene, and xylene, with impressive yields.
