Bras can be made from a variety of unsustainable materials, from water-intensive cotton, to spandex and petroleum-based foam for padding. So once they’re tossed, these synthetic fibers will sit in landfills and take forever to disappear. To lessen bras’ impact on the earth, a lingerie designer has developed the world’s first zero-waste biodegradable bra. The bra features elastic made from sustainably farmed rubber trees as well as organic cotton for sewing thread, and can actually be buried at the end of its lifespan without leaving behind any toxic waste.
