Bio-Based Solutions for Sustainable Electronics in a Post-PFAS Era

The exponential growth of electronic waste poses significant environmental challenges, exacerbated by the widespread use of per- and polyfluoroalkyl substances (PFAS) in electronic components. PFAS, known for their exceptional performance characteristics, have become integral to various electronic devices. However, their persistence in the environment and potential adverse health effects have raised concerns, prompting the European Union to formulate plans for a phased ban on PFAS usage in the near future. This impending regulatory shift necessitates a proactive exploration of viable alternatives to PFAS in electronics. Despite the urgency, the intricate dependence of many electronic components on PFAS poses a unique set of challenges. In this context, our research aims to address this dual challenge by highlighting the critical issues associated with electronic waste and the imminent regulatory restrictions on PFAS. This presentation will delve into the strategies to replace PFAS with bio-derived materials, focusing on the promising potential of lignocellulose-based alternatives. We will present case studies and examples where bio-based materials have been successfully integrated into specific electronic devices, such as batteries and fuel cells, demonstrating the feasibility of a transition towards more sustainable practices. Through our research findings, we seek to contribute to the ongoing discourse on sustainable practices in the electronics industry.
