> In January 2020, BPA was restricted from use in thermal paper, including tickets and receipts, across the EU (3). As a result, another bisphenol, Bisphenol-S (BPS), began to take its place. In fact, an ECHA survey estimated that 61% of all thermal paper would contain BPS as a substitute for BPA, despite concerns of BPS being equally as harmful (6). Fast forward three years and BPS is now recognised as “toxic to reproduction” and a hormone disruptor, and has been added to the EU’s candidate list for Substance of Very High Concern (SVHCs), a common first step on the road to restriction (7).
claims "no BPA/BPS" and "phenol-free". (Hopefully that doesn't turn out to mean that they found something even worse to make it out of!)
It even seems easy to make you own DIY version: squeeze some lemons, unroll, drench, dry and reroll a properly sized roll of normal paper in it.
