Not new, but intriguing nevertheless. Biolucent make a foam pad to reduce the pain some women experience when undergoing breast cancer assessing mammograms. They call it, surprisingly, the Mammopad. The single-use pads come with a return-mail label, so the health facility using the pads can return them to Biolucent, who in turn make them available to Foamex. One of the biggest foam fabricators in the US, Foamex "processes approximately 260 million pounds [118 million kg] of recycled foam each year." The reprocessed Mammopads are apparently used as carpet cushioning, or underlay. ::Biolucent, via a comment on Grist.
