Bionanocomposites offer transformative solutions for sustainable development across diverse sectors, yet their adoption necessitates a robust regulatory framework and adherence to ethical standards. This chapter explores regulatory guidelines that shape the manufacturing, application, and lifecycle management of bionanocomposites, with a focus on compliance with international standards such as ISO and FDA. It addresses challenges in harmonizing regulations across jurisdictions to ensure product safety, quality, and environmental responsibility. The societal impact of bionanocomposites is evaluated through their contributions to healthcare, environmental sustainability, and industrial applications. This analysis includes risk assessments of human and ecological health, encompassing exposure pathways, biodegradability, and end-of-life considerations. Ethical concerns surrounding these materials, including transparency, equitable access, and public accountability, are discussed, proposing a framework grounded in precautionary principles and responsible innovation. Through an interdisciplinary approach, this chapter underscores the importance of establishing unified regulatory and ethical standards to support the safe and equitable integration of bionanocomposites into society, aligning technological progress with sustainable development goals.
