Teko has a line of running/cycling socks made from 100% recycled PET. They told me that they are just as durable and comfortable as your traditional lycra cycling socks.
Another material that was being recycled and reused in new materials was rubber - as in rubber tubes. Bicycling may be an environmentally friendly alternative to driving, but we aren't completely green. One problem is our tires and tubes. It is considerably cheaper for companies to produce tubes from raw butyl rubber than to recycle used tubes. So, what happens to those tubes? One company, Green Guru creates messenger bags, wallets, and other accesories out of recycled tubes.
These bags are made out of recycled tubes. the top one is made from one truck innertube, the bottom one is made out of 6 mountain bike tubes. They also make bags from recycled billboard and hemp.
Cycle Dog makes leashes and collars for man's best friend from recycled bicycle tubes. Hailing from Portland, The owner combined her love for cycling and her love for her dog and came up with a use for all her discarded tubes.
It always helps to have a cute spokesmodel at your booth to draw the crowds
Their collars also have a "pup top" for opening your favorite frosty beverage.
Many other companies were offering products made from recycled, repurposed, or sustainable materials. I can only imagine that number will increase in the future.
