Because they’re typically made of fabric and wire that’s difficult to take apart and repurpose, used bras are among the hardest garments to recycle. But for women who are concerned about the environment (or who are worried about perverts picking through their trash), enter Triumph International, which is now accepting used bras in select Japanese stores and recycling them into power-generating fuel. Triumph started providing free plastic bags to customers in April and May, and it will convert them into refuse-paper-and-plastic fuel for industrial use.
