“…As a cornerstone of the semiconductor industry, its production is crucial for the tech world. In 2022, the global production of industrial silicon reached 7.783 million tons, a figure that also indicates the amount of silicon-containing solid waste generated at each step of the production process [45]. This figure is not just about quantity; it is about the centrality of silicon in our digitally-driven era.…”

In this study, we examine Society 5.0, defined as a future framework where advanced technologies like artificial intelligence (AI), the Internet of Things (IoT), and other digital innovations are integrated into society for sustainable resource management. Society 5.0 represents an evolution from the industrial focus of Industry 4.0, aiming for a harmonious balance between technological progress and human-centric values, consistent with the United Nations Sustainable Development Goals. Our methodology involves a detailed literature review, focusing on identifying and evaluating the roles of AI, IoT, and other emerging technologies in enhancing resource efficiency, particularly in the water and energy sectors, to minimize environmental impact. This approach allows us to present a comprehensive overview of current technological advancements and their potential applications in Society 5.0. Our study’s added value lies in its synthesis of diverse technological strategies, emphasizing the synergy between circular economy practices and sustainable economic development. We highlight the necessity for resilience and adaptability to ecological challenges and advocate for a collaborative, data-informed decision-making framework. Our findings portray Society 5.0 as a holistic model for addressing contemporary global challenges in resource management and conservation, projecting a future where technology aligns with sustainable, equitable, and human-centered development.

“…Recovery of this waste into valuable materials is important to efficiently utilize resources and protect the environment. The transformation of kerf loss Si waste into Si anodes is an attractive approach with high economic profit [4][5][6][7]. Benefiting from an intrinsic tens-of-nanometers-scale thickness, Si waste-derived anodes can demonstrate a high-rate capacity and high cycling stability [8][9][10].…”

The recovery of massive kerf loss silicon waste into silicon anodes is an attractive approach to efficiently utilizing resources and protect the environment. Tens-of-nanometers-scale-thickness Si waste particles enable the high feasibility of high-rate Li-ion storage, but continuous oxidation leads to a gradual loss of electrochemical activity. Understanding the relationship between this oxidation and Li-ion storage properties is key to efficiently recovering silicon wastes into silicon anodes. However, corresponding research is rare. Herein, a series of silicon waste samples with different oxidation states were synthesized and their Li-ion storage characters were investigated. By analyzing their Li-ion storage properties and kinetics, we found that oxidation has absolutely detrimental effects on Li-ion storage performance, which is different to previously reported results of nano-silicon materials. The 2.5 wt.% Si provides a substantial initial discharge capacity of 3519 mAh/g at 0.5 A/g. The capacity retention of 2.5 wt.% Si is almost 70% after 500 cycles at 1 A/g. However, the 35.8 wt.% Si presents a modest initial discharge capacity of merely 170 mAh/g. Additionally, oxidation leads the Li-ion storage kinetics to transform from Li-ion diffusion-controlled to charge transfer-controlled behaviors. For kerf loss silicon waste with an oxygen content over 35.8 wt.%, Li-ion storage capability is lost due to a high charge transfer resistance and a low Li-ion diffusion coefficient.

Organic solar cells (OSCs), especially those employing bulk heterojunction architecture, present a promising avenue in renewable energy technology. These devices utilize organic materials and can be doped by solvents such as dimethylformamide (DMF), tetrahydrofuran (THF), and dimethyl sulfoxide (DMSO). Solvent doping (DMF, THF, and DMSO) is observed to augment the efficiency of OSCs. However, a trade‐off exists between the volume of solvent used and the device's efficiency. The judicious selection of solvents is crucial as it directly impacts the environmental footprint of the fabrication process and the power conversion efficiency. Notably, the use of solvents in OSC fabrication contributes to reducing the environmental impact across various categories, in particular Abiotic Depletion, Global Warming, and Human Toxicity. Among the solvents studied, THF demonstrates the most signiﬁcant reduction in environmental impact. Therefore, optimizing the choice and volume of solvents in OSC fabrication is paramount for achieving both enhanced device performance and minimal environmental footprint.
