There is a lot of interest in creating flexible triboelectric nanogenerators (TENGs) using inexpensive, non-toxic natural materials, owing to a simple and cost-effective process. Utilizing a variety of waste materials, this technology is incredibly effective at transforming untidy environmental energies into green electricity for a range of ingenious applications. Herein, we have developed a novel water hyacinth root (WHR)-based green triboelectric nanogenerator (TENG) for self-powered sensing applications. For the construction of the TENG, WHR is affixed to fabrics to function as one triboelectric layer, while human skin serves as the opposing triboelectric layer. Water hyacinth roots are abundantly accessible and inexpensive, decreasing TENG production costs and providing an ecologically friendly and cost-free alternative to more expensive materials. Furthermore, the water hyacinth root is crucial for promoting environmentally friendly development, as it converts bio waste into a sustainable energy source, thereby creating an economy that prioritizes sustainability. WHRs exhibit fine fibers, sufficient tensile strength &amp; flexibility, a rich composition of cellulose and lignin, rough texture, and abundant functional groups, which play a key role in demonstrating the electron-accepting ability of the WHRs. Based on the potential of this device, we have a power density of 5 W m<small>⁻²</small> and a sensitivity of 3.2 V kPa<small>⁻¹</small>. The electrical output was analyzed under various mechanical stimuli, proving its durability and reliability in energy harvesting. The current study anticipated employing natural waste to create healthcare monitoring, tactile sensing, and energy-harvesting devices, as well as potential uses in self-powered sensors for various security applications, Internet of Things (IoT), and human–machine interfaces. The WHR-TENG-based self-powered sensor exhibited an identification accuracy of 99.3% using a deep learning algorithm. Therefore, this work proves the need to develop waste-material-based TENGs for environmentally-friendly and economical self-powered devices.</p>","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 15","pages":" 4198-4208"},"PeriodicalIF":5.0,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144671315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its lead content raises serious environmental and health concerns, prompting the search for more sustainable alternatives. In this work, we explore whether a lead-free composite based on the halide perovskite FASnI₃ embedded in a polyvinylidene fluoride (PVDF) matrix could serve as a viable substitute for PZT in piezoelectric energy harvesting applications. To assess this potential, we conduct a comparative life cycle assessment (LCA) of both materials in thin-film device configurations, following a cradle-to-grave approach. The analysis includes the environmental impacts of raw material extraction, manufacturing, potential energy recovery during use, end-of-life treatments, and accidental release scenarios. The results show that PZT-based devices have consistently higher environmental impacts across all life cycle stages, mainly due to the high energy requirements for their synthesis and thin-film deposition, as well as the use of lead. In contrast, the FASnI₃-PVDF composite benefits from low-temperature processing and the absence of lead, resulting in significantly lower impacts during manufacturing and the use phase.

Therefore, it is essential to either deactivate or discharge LIBs prior to any mechanical processing step. As recycling is a key activity to transform from a linear economy into a circular one, the evaluation of a discharge step from the perspective of circular economy (CE) is essential but remains largely unexplored. In this work, battery discharge systems using three different Na<small>⁺</small>-based aqueous solutions (<em>i.e.</em>, NaCl, Na<small>₂</small>SO<small>₄</small>, and Na<small>₂</small>CO<small>₃</small>) were modelled with HSC® process simulation software.

Statistical entropy only evaluates the concentrating action of different components in a system, without discriminating whether the produced streams are in a usable chemical form or irreversibly changed. Thus, a weighting factor for irreversible transformations was implemented for statistical entropy analysis. Exergy analysis revealed that the discharge systems do not significantly destroy energy, although it was unexpectedly revealed that corrosion aids in exergy preservation by producing highly concentrated hydrogen from the water splitting reaction.
