Eco‐friendly triboelectric nanogenerator (eco‐TENG) is considered as a next‐generation renewable kinetic energy‐harvesting technology, especially for its potential use as a power supply unit for self‐powered electronics. For eco‐TENGs, nature‐derived biomaterials, which are non‐toxic to human and environment, highly biocompatible, and abundant in nature, are used for tribopositive or tribonegative materials, or both. Here, recent progress in nature‐derived biomaterials exploited for eco‐TENGs and their energy‐harvesting performances are reviewed, focusing on refined, hybridized, post‐treated, or not. Since biomaterials that exist in nature have evolved over hundreds of years to hundreds of thousands of years, their diversity, novelty in physicochemical structure, and high safety to nature hold enormous potential as carbon‐neutral energy materials. Furthermore, scalability and cost‐effectiveness of their fabrication methods make them promising as industrially viable eco‐materials.

Wood is a renewable resource with excellent qualities and the potential to become a key element of a future bioeconomy. The increasing environmental awareness and drive to achieve sustainability is leading to a resurgence of research on wood materials. Nevertheless, the global climate changes and associated consequences will soon challenge the wood-value chains in several regions (e.g., central Europe). To cope with these challenges, it is necessary to rethink the current practice of wood sourcing and transformation. The goal of this review is to address the intrinsic natural diversity of wood, from its origin to its technological consequences for the present and future manufacturing of wood products. So far, industrial processes have been optimized to repress the variability of wood properties, enabling more efficient processing and production of reliable products. However, the need to preserve biodiversity and the impact of climate change on forests call for new wood processing techniques and green chemistry protocols for wood modification as enabling factors necessary for managing a more diverse wood provision in the future. This article discusses the past developments that have resulted in the current wood value chains and provides a perspective about how natural variability could be turned into an asset for making truly sustainable wood products. After briefly introducing the chemical and structural complexity of wood, the methods conventionally adopted for industrial homogenization and modification of wood are discussed in relation to their evolution toward increased sustainability. Finally, a perspective is given on technological potentials of machine learning techniques and of novel functional wood materials. Here the main message is that through a combination of sustainable forestry, adherence to green chemistry principles and adapted processes based on machine learning, the wood industry could not only overcome current challenges but also thrive in the near future despite the awaiting challenges.
