Sustainable Utilization of Euphorbiaceous Fibers: A Review of Green Processing Methods

The global push for a carbon-negative bioeconomy has positioned the Euphorbiaceae family particularly resilient species like Euphorbia tirucalli as critical feedstocks for industrial applications.This review introduces the concept of "Integrative Green Valorization," a paradigm shift that moves beyond simple fiber extraction to a holistic biorefinery approach.We evaluate 2026standard green processing methods, A unique highlight of this review is the analysis of in-situ functionalization, where residual Euphorbiaceous latex rich in terpenoids and polyisoprene is repurposed as a natural, "bio-coupling" agent.Recent data shows that replacing up to 40% of synthetic resins with this "euphorbia coagulum" can increase the bending strength of bio-composites by 50% while simultaneously reducing water absorption by 68%.Furthermore, the review explores the emerging role of digital twin modeling in 2026 to predict fiber crystallinity and interfacial bonding, enabling the custom-engineering of Euphorbiaceous fibers for high-performance automotive and medical textiles.By synthesizing these cross-disciplinary advancements, this paper provides a strategic roadmap for transforming drought-resistant Euphorbiaceous biomass into a high-value, circular resource for 2026 and beyond.
