Let's say you're walking down a street, you spot some old wood left out by the trash, and you feel it could be given a second life in the right hands - but that you don't necessary have the space or skills for it. What do you do, and how can you share this information with others? Trashswag, a small Canadian start up, allows you to map pictures of valuable trash and to share them on their website and mobile application. The site has been designed to help artists and other creative minds with an interest in upcycling and reuse to easily share the location of unique and aged materials found in the streets. The primary goal of trashswag is to help people to find free objects to make cool projects, it is based on the idea crowdsourcing, or in this case, crowd-mapping.
