The document discusses the production of synthetic fibres from polylactic acid (PLA), which can be produced from corn. PLA fibres have properties similar to nylon and polyethylene terephthalate but are derived from renewable resources. PLA can be used to produce apparel, carpets, packaging and other products. While PLA fibre markets benefit consumers directly, PLA packaging markets depend more on manufacturers adopting the materials for environmental benefits. Long term, PLA could compete in markets worth over $10 billion annually if production costs decrease.
