Summary: This research aims at contributing to the assessment and improvement of sustainability of the chemistry behind leather manufacturing by applying Life Cycle Assessment (LCA) to explore environmental issues. The study found that the major production hotspots are in the consumption of electricity and phosphoric acid, and it may lead to the identification of new chemical formulations for improving environmental sustainability.

Summary: 3D printing in construction industry aims to improve economics and reduce environmental impacts. The study compared the eco-efficiency and economics between 3D printing and traditional construction methods, showing that 3D printed houses have lower environmental impacts and higher cost savings compared to conventional concrete construction. Sensitivity analysis suggests that reducing cement ratios can further mitigate environmental impacts in 3D printing.

Summary: Due to the depletion of natural resources, increased energy use, and environmental, economic, and social imbalance, organizations are striving to identify strategies for reducing their impacts on sustainability. However, many manufacturing industries struggle in identifying the key elements that influence their contributions to sustainability and managing the calculation of these effects. This article aims to incorporate sustainability practices into manufacturing by developing a set of key performance indicators (KPIs) for assessing and improving environmental and economic management practices.

Summary: Additive manufacturing (AM) is increasingly used for custom final part production, but printing speed and production volume are barriers for large-scale adoption. This paper proposes integrating AM with traditional mass customization (MC) technologies to address these challenges. The results demonstrate that combining AM with MC can benefit manufacturers in customer-centric strategies, leading to significant profit improvements.

Summary: Transparency is crucial for supporting scientific claims in Life Cycle Assessment (LCA) studies, but the disclosure of secondary datasets and analysis scripts of models is still relatively low. The use of open-source programming languages can enhance transparency and reproducibility. It is also important to disclose secondary datasets and provide justifications for their selection to ensure accurate interpretation of LCA results.

Summary: This study evaluates the CO2 emission reduction potential from large-scale vehicle electrification in China. Results show that while emission savings were not achieved in 2018, they could increase up to 49.64 million tons in 2030, with fuel economy identified as a crucial factor for emission mitigation.

Summary: Prospective life cycle assessment (LCA) studies are widely used to evaluate emerging resource recovery systems, with engineering-based upscaling calculations being more resource-efficient than simulations for generating life cycle inventory (LCI). This study tested the validity of an engineering-based upscaling method for LCI generation in biochemical resource recovery processes, finding substantial differences in methane production between actual and conceptual plants. The results showed sensitivity to biogas generation amount in various impact categories, with different estimations of fugitive emissions impacting global warming potential results significantly.

Summary: The study compared the environmental impacts of sc-Si glass-backsheet and glass-glass modules produced in China, Germany, and the EU, showing lower impacts for glass-glass modules and for production in Germany and the EU compared to China. The study emphasizes the significant levers for future reductions of environmental impacts, such as module efficiency, energy requirements, silicon consumption, and carbon intensity of electricity during production. The importance of up-to-date inventories and current modeling of electricity mixes for representative LCA results of PV modules is highlighted.
