Dr. S. P. Abbas presented on measuring sustainability in the textile manufacturing chain. Life cycle assessment considers environmental impacts from raw materials through production, use and disposal. Key metrics include carbon footprint, water footprint and resource utilization of water, energy and chemicals. Measuring also includes social responsibility assessments. Solutions are complex given lack of a single definition of "sustainable textile" and different environmental impacts of natural versus synthetic fibers across the full lifecycle.

Most precious metals are con

even though they are not nat

recycled because they are no

extraction and use.
