The uniforms will be worn by the home team at next year’s games in Tokyo.

Asics hopes to gather 30,000 items through collection boxes in stores and at sporting events.

It comes as the fashion industry faces increasing pressure to make more sustainable clothing.

Asics said the uniforms will be made from polyester extracted from donated items.

Other recyclable materials extracted from the items collected will be turned into fuel, among other uses, the firm said.
