That fading receipt in your wallet might be more of a problem than you think. For decades, the thermal paper industry, a market valued at around $2 billion, has relied on a chemical cocktail that includes Bisphenol A (BPA). Yes, that is the same BPA that parents worry about in baby bottles and water jugs. It mimics estrogen, messing with our hormones in ways we are only just beginning to understand. While regulators in the EU have cracked down on BPA, manufacturers can pivot to “alternatives” like Bisphenol S (BPS). It sounds different, but chemically, it is the same wolf in sheep’s clothing, exhibiting toxicological properties eerily similar to the villain it replaced. Now, in a new study, researchers have developed a safer, sustainable alternative to BPA-laden thermal paper using “washed” lignin from wood and sugar derivatives. The result is a receipt that prints clearly without disrupting your hormones.
