Levi Strauss & Co. conducted a lifecycle assessment in 2007 that revealed the significant environmental impact of their jeans production. This inspired them to innovate more sustainable styles using recycled materials. Their 2013 Waste<Less collection utilized over 3.5 million recycled bottles, with each pair containing at least 20% recycled polyester made from 8 plastic bottles on average. Nike also uses recycled plastics for their uniforms, with their 2010 World Cup jerseys made from 13 million recycled bottles.
