A sustainable football stadium made from old sneakers debuted in Chengdu, the capital city of southwest China's Sichuan Province.
A total of 40,000 pairs of discarded sneakers were turned into recyclable materials and reborn as nearly 800 square meters of ground cushions, chair cushions and entry floor mats.
Meanwhile, shoelaces were also given a new lease of life and repurposed as goalpost nets in the stadium.
