The Chemistry of White: ECF vs. TCF Bleaching & Safety Standards
The Science of Whiteness: Navigating Chemical Safety in ECF and TCF Bleaching. Achieving an 88% ISO brightness target requires a technical balance between lignin removal and chemical effluent management. This report deconstructs the operational performance of Elemental Chlorine Free (ECF) versus Totally Chlorine Free (TCF) standards, auditing the TEQ toxicity quotients of 2,3,7,8-TCDD benchmarks. From the mechanical advantages of unbleached sulfate pulp to the toxicological safety of FB-220 optical brighteners, discover a data-driven framework for meeting Green Seal GS-18 compliance and optimizing your 2026 global hygiene supply chain.
