Fiber, textile, carpet, and apparel industries form one of the largest manufacturing sectors in the United States, employing over one half million workers with an annual payroll exceeding $15 billion. 17 billion pounds of fibers is consumed by the industries with 3.5 billion pounds used in carpet manufacturing. Most of the fibrous products are purchased as replacement, resulting in over 14 billion pounds of fibrous waste (apparel, carpet, and textiles) being disposed of in landfills each year. As consumer demand for recycled products, landfill costs and environmental regulations increase, treating this large amount of fibrous waste as a resource for raw material by converting it into useful products is the most desirable solution. Toward this end, significant research has been carried out by industry and academia with the support of various government agencies, leading to many commercial operations. This paper reviews some of the fiber recycling technologies, with a focus on work conducted at the Georgia Institute of Technology.
