Beer waste may become sunscreen ingredient after spent hops show promising UV protection

Research conducted at the University of São Paulo (USP) in Brazil revealed that hops (Humulus lupulus L.) industrial waste from the brewing industry is a viable option for sunscreen formulation production. The multidisciplinary study, which involved researchers from USP's School of Pharmaceutical Sciences (FCF), was inspired by the large amount of waste generated and discarded during beer production. The study brought together complementary expertise in natural products and bioactive photoprotection.
