A waste product from paper-making could be a safer, greener alternative to using the harmful chemical bisphenol A (BPA) in plastic products.

BPA is banned from baby bottles due to its possible effects on the body and brain by mimicking the hormone oestrogen. Approximately 3.5 million tons of BPA are produced annually worldwide in sports equipment, glues and receipt paper.
