A little bit out of date but still a good example of Upcycling entrepreneurship. Have you ever seen the mess left behind at the UK festivals? One thing that is often left behind is tents, often because they are either damaged or considered not worth uprooting and repacking since they are so cheap to replace.
To combat the effect of this on the environment and take advantage of the free material a British company has started producing clothing and accessories that would be ideal for taking back to the festivals next year. UK based WiTHiNTENT produce rain jackets and bags and will have stalls at Glastonbury.
