Sustainability is about impact. To compare the impact of different materials, you have to understand the environmental impact (energy, water, CO2, etc.) each material has throughout the supply chain. This is done by an LCA (Life Cycle Assessment). An LCA models the complex interaction between a material and the environment, within a certain production cycle.

To compare the impact of Polylana® fiber vs. acrylic fiber, we have worked closely with Textile Exchange. Textile Exchange is a global non-profit that works with their members to drive industry transformation in preferred fibers, integrity and standards and responsible supply networks. In close collaboration with Brown and Wilmanns Environmental LLC, Textile Exchange studied and concluded available LCA data and information with detailed literature reviews of widely used different fibers and materials within the textile industry. Based on these validated studies, we can publish below LCA data for Polylana® vs Acrylic per 1 kilo undyed fiber:
