Interest in nanomaterials from plants increased due to increased demand for environment-friendly materials. The materials are characterized by attributes that make them ideal for practical applications in several industries. On a comparison of traditional materials with the present research, this chapter assesses plant-based nanomaterials economic viability for their production in accordance with cost-efficient procurement, processing, and manufacture. From raw material extraction to final product manufacture, we address every stage of the value chain, therefore stressing important elements influencing economic feasibility including resource availability, production scalability, and technology needs. Targeting sectors where the materials can have a major impact, such packaging, medicine, cosmetics, and agriculture, the chapter also investigates the market possibilities for plant-based nanoparticles. Emphasized were regulatory settings impacting market environments, consumer preferences for environmentally friendly products, and new trends. Using case studies, the illustration of the commercialization efforts’ success and innovations of plant-based nanomaterials emphasizing their performance characteristics and correspondence with circular economy is shown. The chapter provides a detailed examination of the viability and development potential of plant-based nanomaterials by considering economic and market perspectives. It also emphasizes the need of more research and financing to realize the possibilities of such resources in the creation of a sustainable future.
