Things They Should Invent: a device that automatically separates menstrual blood from used feminine hygiene products

Yesterday we learned that they can make stem cells from menstrual blood.

So now we need an effective way to harness all the menstrual blood that people throw out every month in their used pads and tampons. We need some way to take all the used FHPs from those bins in public washrooms and throw them all in a giant machine or something and separate out the menstruation. You know how for the Toronto green bin program they came up with a way to automatically separate plastic bags from organic waste, so people could sanitarily wrap their organic waste in plastic before throwing it out? We need something similar for FHPs and menstruation. Then we'll have an infinite supply of stem cells.
