Alternative Raw Materials for Currency Substrate Production

The Bureau of Engraving and Printing (BEP) has issued a Request for Information (RFI) to gather data on alternative raw‑material paper substrates that could replace or supplement traditional cotton‑linen currency paper. Respondents are asked to describe material composition, performance metrics, security‑feature compatibility, sustainability attributes, manufacturing considerations, and cost estimates for natural fibers (hemp, flax, bamboo, etc.), engineered fibers (nanocellulose, regenerated cellulose), synthetic polymers, and hybrid substrates. The goal is to assess technical viability, durability, security integration, environmental impact, supply‑chain resilience, and potential cost savings for future currency production. • Provide detailed material description, commercial readiness, and existing applications. • Supply performance data (tensile strength, tear resistance, longevity, etc.). • Demonstrate compatibility with watermark, security thread, and other anti‑counterfeiting features. • Outline printing performance for offset, intaglio, letterpress, and foil processes. • Include sustainability metrics (renewable content, recyclability, carbon footprint). • Discuss manufacturing capacity, scalability, and estimated production costs. • Submit supporting lab results, certifications, and IP disclosures. Responses are limited to 50 pages and due by 5:00 PM ET on December 11, 2026.
