Driven by the escalating environmental impact of synthetic materials, there has been a growing focus on employing eco‐sustainable biomass‐derived biopolymers and native materials as a viable alternative to traditional energy storage applications. Biopolymer‐based energy devices, like batteries, supercapacitors, electrode materials, and ion‐exchange membranes, a novel and eco‐conscious approach, hold great potential for flexible and smart electrochemical energy storage and conversion devices, owing to their affordability, environmental sustainability, and biodegradability. This critical review outlines the sources and properties of biopolymers leading to energy storage and emphasizes their utilization in the energy sector. Despite their inherent constraints, biopolymers can be effectively leveraged when combined with other materials in composites. This collaborative approach not only refines their intrinsic physical attributes but also elevates the electrochemical performance of biologically active molecules. In this regard, bionanocomposites, a class of materials combining biopolymers and nanoparticles, have emerged as a promising greener alternative to conventional petroleum‐based polymers. Their biocompatibility, biodegradability, and antimicrobial properties have promoted their increased commercialization, thus paving the way for a more sustainable future. The review concludes by identifying and effectively addressing the limitations, challenges, and future perspectives of biopolymers in energy storage applications.

“…The demethylation of lignin involves the conversion of the methoxy group in the active part of the aromatic ring of lignin to a phenolic hydroxyl group. [43] This modification can effectively increase the activity of lignin, as well as the number of corresponding active sites to a certain extent. [44] Lignin prepared by this method is a suitable substitute for phenol in ligninbased PF resin adhesives.…”

Traditionally, phenols used to prepare phenol‐formaldehyde (PF) resin adhesives are obtained from phenolic compounds and various chemicals, which are extracted from petroleum‐based raw materials. Lignin, a sustainable phenolic macromolecule in the cell wall of biomass with an aromatic ring and a phenolic hydroxyl group similar to those of phenol, can be an ideal substitute for phenol in PF resin adhesives. However, only a few lignin‐based adhesives are produced on a large scale in industry, mainly because of the low activity of lignin. Preparing lignin‐based PF resin adhesives with exceptional achievements by modifying lignin instead of phenol is an efficient method to improve the economic benefits and protect the environment. In this review, the latest progress in the preparation of PF resin adhesives via lignin modification, including chemical, physical, and biological modifications, is discussed. In addition, the advantages and disadvantages of different lignin modification methods for adhesives are compared and discussed, and future research directions for the synthesis of lignin‐based PF resin adhesives are proposed.

The proliferation of polymer science and technology in recent decades has been remarkable, with synthetic polymers derived predominantly from petroleum-based sources dominating the market. However, concerns about their environmental impacts and the finite nature of fossil resources have sparked interest in sustainable alternatives. Bio-based polymers, derived from renewable sources such as plants and microbes, offer promise in addressing these challenges. This review provides an overview of bio-based polymers, discussing their production methods, properties, and potential applications. Specifically, it explores prominent examples including polylactic acid (PLA), polyhydroxyalkanoates (PHAs), and polyhydroxy polyamides (PHPAs). Despite their current limited market share, the growing awareness of environmental issues and advancements in technology are driving increased demand for bio-based polymers, positioning them as essential components in the transition towards a more sustainable future.
