Sustainability and Traceability—Core Pillars of Raysileco
The raw material for Raysileco yarn is wood pulp responsibly sourced from FSC-certified softwood and hardwood forests, ensuring no deforestation or environmental damage, and supporting biodiversity conservation.
The yarn is 100% natural and biodegradable, offering an eco-friendly alternative to synthetic fibers and reducing the fashion industry’s carbon footprint.
Full traceability leverages digital tracking and documentation systems, allowing stakeholders—including brands, retailers, and consumers—to access transparent information regarding the origin, processing steps, and environmental impact of the yarn.
This traceability credentials help brands meet increasingly stringent regulatory requirements and sustainability commitments, while offering end consumers greater confidence in product authenticity and ecological responsibility.
