Carbon dots (CDs) are luminescent carbon nanoparticles with significant potential in analytical sensing, biomedicine, and energy regeneration due to their remarkable optical, physical, biological, and catalytic properties. In light of the enduring ecological impact of non-biomass waste that persists in the environment, efforts have been made toward converting non-biomass waste, such as ash, waste plastics, textiles, and papers into CDs. This review introduces non-biomass waste carbon sources and classifies them in accordance with the 2022 Australian National Waste Report. The synthesis approaches, including pre-treatment methods, and the properties of the CDs derived from non-biomass waste are comprehensively discussed. Subsequently, we summarize the diverse applications of CDs from non-biomass waste in sensing, information encryption, LEDs, solar cells, and plant growth promotion. In the final section, we delve into the future challenges and perspectives of CDs derived from non-biomass waste, shedding light on the exciting possibilities in this emerging area of research.
碳点（CDs）是发光碳纳米颗粒，由于其卓越的光学、物理、生物和催化特性，在分析传感、生物医学和能量再生方面具有巨大潜力。鉴于非生物质废物在环境中持续存在的持久生态影响，人们已努力将非生物质废物，如灰烬、废塑料、纺织品和纸张转化为碳点。本综述介绍了非生物质废碳源，并根据《2022年澳大利亚国家废物报告》对其进行分类。全面讨论了合成方法，包括预处理方法，以及源自非生物质废物的碳点的性质。随后，我们总结了源自非生物质废物的碳点在传感、信息加密、发光二极管、太阳能电池和促进植物生长等方面的多样应用。在最后一部分，我们深入探讨了源自非生物质废物的碳点未来面临的挑战和前景，揭示了这一新兴研究领域令人兴奋的可能性。
