Summary: The study shows that adding non-plastic waste materials to plastic clay during brickmaking process at a laboratory scale does not significantly affect the main technological properties of the semi-finished and finished products. However, the mechanical strength of the dry and fired products decreases due to microstructural factors. The different effects on the technological properties of clay bricks are correlated to the type of waste added as degreasers and the complex interplay of particle size distribution and mineralogical composition in the ceramic matrix.

Summary: This study is the first to investigate the association between objectively measured evening physical activity and sleep within a real-world big-data sample. The findings suggest that evening physical activity is not significantly associated with sleep quality, but may lead to a slight increase in sleep duration when engaging in moderate-intense physical activity.

Summary: The utilization of waste electrical and electronic equipment (WEEE) as a source of valuable raw materials, including rare earth elements and metals, is essential for the circular economy. A laboratory study found that under specific conditions, indium can be efficiently leached from waste liquid crystal displays using an H2O:HCl:HNO3 solution with ultrasound treatment, achieving a 98% leaching efficiency. This research provides a practical reference for the recycling of indium from LCD panels.

Summary: The article highlights the need for nonanthropocentric actions and decision-making to address the biodiversity crisis, and explores how the conflation in capital taxonomy in traditional economics hinders understanding of nonanthropocentric economic frameworks. It emphasizes the importance of considering interspecies distributive justice and human well-being in economic decision-making.

Summary: The study focuses on the valorization of food and agricultural by-products through emerging processing methodologies, specifically pectin extraction. It found that emerging thermal and non-thermal technologies, as well as their combinations, have been successfully used for pectin extraction with higher yields and desired quality. However, the industrial application of these technologies faces challenges such as high capital costs, limited expertise, and insufficient data on process scaling up. Further research and training in food processing are recommended for overcoming these challenges.

Summary: The study systematically analyzes the energetic performance of nanopore-based power generation (NPG) at various process scales, revealing limitations in linearly extrapolating single-pore performance to multipore membranes. The research shows that enhancing nanopore properties has limited impact on practical process performance, and a tradeoff exists between power density and thermodynamic energy efficiency in full-scale NPG membrane modules. Additionally, the study explores the theoretical maximum energy efficiency of NPG and concludes that practical energy efficiency is limited to 42%, making the current NPG process not viable for power generation.

Summary: There is a growing movement towards plant-based diets in public health. This publication evaluates the protein quality of pistachios and emphasizes their role in providing ready-to-eat, high-quality plant-based protein. Pistachios are complete proteins, containing all nine essential amino acids, and they have a higher protein digestibility-corrected amino acid score (PDCAAS) compared to other tree nuts. Transitioning towards plant-based diets, including nuts like pistachios, could have environmental benefits by reducing water footprints. However, dietary guidelines should consider incorporating nuts into daily diets for their health and environmental outcomes.

Summary: This paper introduces the hypothesis of the carbon emission efficiency curse, which suggests that increased natural resource dependence can have a negative impact on carbon emission efficiency. Empirical results from panel data of 283 cities in China from 2004 to 2017 support this hypothesis, demonstrating the mechanisms through which natural resource dependence affects carbon emission efficiency.

Summary: This article discusses the importance of emotions in response to ecological crises and how they contribute to our wellbeing. By focusing on eco-anxiety and analyzing a wide range of studies using methods from philosophy, emotion theory, and interdisciplinary environmental studies, the authors demonstrate how understanding anxiety in general can help develop better models of eco-anxiety. The results suggest that eco-anxiety refers to a family of distinct but related ecological emotions, and that practical eco-anxiety can be a valuable emotional response to address threats like climate change, benefiting both individuals and the planet.

Summary: Chemical precipitation thermodynamic modeling was used to evaluate the effect of solution factors on the crystallization of vivianite. The results showed that solution pH influenced ion concentration, and the initial Fe2+ concentration impacted the formation of vivianite. pH 7.0, initial Fe2+ concentration 500 mg/L, and Fe:P molar ratio 1.50 were the optimal conditions for phosphorus recovery.

Summary: Large quantities of mismanaged plastic waste pose a threat to the health and well-being of billions worldwide, particularly in low- and middle-income countries. Burning discarded plastic in open fires, a self-management strategy adopted by 2 billion people, releases chemical substances and particles that may pose serious risks to public health and the environment. Research on the potential harm of open burning emissions remains underexplored, with waste pickers being identified as a high-risk group exposed to harmful substances.

Summary: The rationale of this article is to clarify waste management goals and investigate the attention on these goals in scientific publishing. The study reveals that there is little attention given to waste management goals in scientific publications. The authors recommend greater focus on waste management goals and call for awareness and action from editors, authors, reviewers, and professional associations in the field.
