Using lignin and a catalyst to create an alternative to bisphenol A (BPA)

"compounds called bisguaiacols, all of which are based on the use of lignin, a key component of wood. The bisguaiacols are created by inciting reactions between an alkene and a bio-based arene (such as guaiacol)—all set off by H-USY, a recyclable zeolite catalyst. The researchers confirmed that their compounds could be used to make cleaner and healthier plastics. Initial testing also failed to find toxicity in humans"
