Selective dye and pigment removal using porous carbon fibers

Overview

Waste2Wealth Inc presents a novel solution for the selective removal of dyes and pigments using advanced porous carbon fibers. This technology targets the extraction of charged or polarizable dye molecules from thermoplastic polyurethane (TPU) in organic media. The solution leverages the unique properties of porous carbon fibers, making it highly effective for industries dealing with dye-laden materials.

Technical specifications

Key features:

• Porous carbon fibers: Developed to selectively capture dye and pigment molecules.
• Adaptability: Effective in both aqueous and organic media, specifically designed for TPU applications.
• Efficiency: High dye/pigment removal efficiency, tested and validated in controlled environments.

The process involves immersing the TPU containing dyes and pigments in organic media, followed by the introduction of porous carbon fibers to extract the unwanted molecules.

Technology readiness level

This technology is currently at TRL 4, having been validated in a laboratory setting. The next steps include scaling the production of porous carbon fibers and optimizing the process for industrial applications.
