Summary: There is a growing global problem of industrial by-product accumulation, and Australia is not exempt. Nu-Rock offers a reliable solution by converting waste from coal fired power stations into high-quality masonry products for the construction industry. A detailed life-cycle analysis was conducted, considering both cost and environmental impacts. The study found that Nu-Rock can produce a large volume of products equivalent to traditional building materials, with prices comparable to common bricks, while offering superior environmental benefits.

Summary: This study assessed the environmental impact of Spanish virgin olive oil production, focusing on both farming and industrial phases. Significant differences were observed in the farming phase, primarily due to the virgin olive oil yield of each harvest season. The environmental impact of the industrial phase remained relatively constant, with pomace valorization accounting for a significant portion of the overall impact.

Summary: In recent years, the design of asphalt mixtures has become more complex with the introduction of additives and innovations. Traditional volumetric-based mix designs may lead to premature failure in the field. Therefore, a transition to performance-based mix design is required, along with considerations for life-cycle costs and environmental impact.

Summary: This paper calculates the long-lasting carbon sequestration (LLCS) of seaweed using a life cycle assessment approach, with kelp in Ailian Bay as an example. The results show that the carbon sequestration of kelp in Ailian Bay is 97.73 g C m(-2) year, with biomass carbon accounting for approximately 86% of the total carbon absorption. The study demonstrates that mass production of seaweed can be an efficient method for carbon sequestration and for evaluating the impact of kelp farms on climate change.

Summary: Aquaculture is seen as a potential solution to meet increasing fish demand, but it must reduce its use of wild fish in feed and minimize environmental impacts. The integrated multi-trophic aquaculture system shows promise in mitigating adverse effects. The dynamic energy budget (DEB) modelling can assist in achieving sustainable goals. This study explores the potential of mussel farming for bioremediation and sustainable fish farming in the Baltic Sea region.

Summary: Isopropanol and acetonitrile are important chemical raw materials with difficulty to separate when mixed with water due to the formation of azeotropes. A heat pump-assisted extractive distillation process was proposed to reduce energy consumption, while the pervaporation-distillation hybrid process was studied to improve efficiency. Life cycle assessment showed that the hybrid process had lower cost and energy consumption, as well as smaller global warming potential and acid potential compared to other processes.

Summary: In this study, UAV photogrammetry was used to monitor crop height in a flooded paddy field. The results showed that UAV with higher accuracy GNSS receiver obtained more reliable estimations, while the UAV with moderate accuracy GNSS receiver also performed well. The performance of CHMs created by different methods was less affected by treatments, but more uniform distribution of vegetation over the water surface led to better performance.

Summary: This study investigated the effects of different tillage and cover crop systems on soil biological indicators in Andosols in a humid subtropical climate in Japan. The results showed that no-tillage (NT) and rye (RY) systems increased soil respiration and organic carbon stocks. The influence of tillage systems on the soil microbial community and biomass was greater than that of cover crop treatments.

Summary: No-tillage is a promising practice to improve soil quality and potentially increase crop yield. Meta-analysis of 64 peer-reviewed articles demonstrated that no-tillage significantly increased soil organic carbon content and storage compared to conventional tillage. It also improved soil physical and chemical properties and had slight positive effects on crop yield.

Summary: Shade stress is a serious concern in soybean cultivation, but the application of molybdenum (Mo) and phosphorus (P) can enhance photosynthesis and improve soybean growth under low-light conditions. This study found that Mo and P treatments increased the growth, photosynthetic capacity, and nutrient absorption of soybean, resulting in higher biomass compared to plants without Mo and P applications.

Summary: No-tillage combined with a rye cover crop has the potential to contribute to environmental conservation in organic agriculture by reducing energy consumption and carbon footprint. Although no-tillage may result in decreased yield, the use of a rye cover crop can mitigate the yield reduction. The no-tillage system with a rye cover crop has the potential to be an environmentally friendly and sustainable cropping system with high yield, energy efficiency, and low carbon footprint.
