Can recycled paper really be “contaminated”?
In response to a reader asking whether paper receipts are recyclable, Grist’s Umbra says,
… As always, I recommend checking with your local waste agency, but I can tell you that receipts are usually coated with BPA, and evidence including this recent study suggests that BPA can contaminate other recycled-paper products. So avoid accepting receipts when you have the choice, and when they pile up, I give you permission to throw them out. Sometimes it just feels good.
But there’s not much BPA on receipts — much less in recycled paper. And when BPA is absorbed through the skin, it is rapidly metabolized into estrogenically inactive water soluble metabolites that are excreted.
