Japan's Uniqlo casual clothing chain is to expand its recycling programme to include used Uniqlo-brand clothes that will be reprocessed for industrial use or donated to charity.

The current recycling programme involves used fleece jackets, which can be dropped off twice a year at the chain's 730 domestic outlets.

Uniqlo spokeswoman Keiko Yamamoto told Associated Press that useable clothes will be donated to charities while others will be reprocessed to be used as heat insulation or fuel.

The company eventually hopes to expand its recycling campaign to other countries besides Japan.
