The growing concern over the environmental impacts caused by plant agriwaste has intensified the search for sustainable alternatives in manufacturing processes. This review explores the valorization of agro-industrial residues, such as those derived from banana, coconut, and pineapple, for example. It highlights their potential to be converted into value-added products, particularly within the textile sectors. Emphasis is given to the environmental and economic benefits of reusing biomass rich in fibers and bioactive compounds while discussing key technological, regulatory, and logistical barriers that still limit large-scale applications. In parallel, it presents recent advances in processing technologies, such as biocomposites and biochar, and the integration of circular economy principles to promote resource efficiency and waste reduction. The analysis also underscores the importance of public policies and financial incentives to drive innovation and ensure the viability of sustainable practices in industrial contexts. The article proposes an ideal circular production flow model that contrasts current linear practices with a regenerative, bio-based alternative. By mapping current challenges and future perspectives, this review expects to contribute to the debate on environmental responsibility, green technologies, and the economic potential of plant residue reuse in manufacturing chains.
