The shoe recycling facility in Nanbaixiang, outside Wenzhou, is one of the largest in China, with shoes arriving by the truckload from all over the country.
Xie Yu-bing heats rubber shoe soles so that the remaining upper sole can be easily ripped away using a pair of tongs. The rubber is then recycled.
He says: "I earn 30 RMB a day ($3.74) doing this work. I don't worry too much about the burning rubber fumes, but I am looking for another job".
