Eco-Ink Symbols on Neck Labels for Differentiating Sustainable and Chemical Ink in Clothing Recycling

As concerns over textile waste and its environmental consequences grow, efficient garment recycling practices are becoming increasingly vital. One challenge in recycling is distinguishing between eco-friendly and chemical inks used in garment labels. This study proposes a practical solution by printing a simple eco-ink symbol directly onto the neck label of garments. The neck label is chosen for its durability and high visibility, ensuring the eco-ink symbol remains intact throughout the garment’s life cycle. This labeling method enables recyclers to easily identify and segregate garments printed with sustainable inks from those using chemical-based alternatives. By streamlining the identification process, this approach enhances recycling efficiency, reduces contamination in material streams, and supports the circular economy by promoting the reuse of textiles with minimal environmental impact. This paper explores the feasibility, advantages, and potential challenges of implementing this labeling system in garment recycling.
