Was just thinking about this. It seems quite a waste to throw away strings which are predominately a form of plastic. Nylon is consistently recycled in the form of carpets, and polyester is actually a very great sustainable resource for the textile industry. It goes into clothing quite often, and in fact, Patagonia uses predominately recycled poly in their clothing. Now, I'm not ignorant to the fact that there are different types of each, but it seems wasteful to throw away synthetic strings which may be able to be re-used. Anyone know of a way to recycle used tennis strings?
