Yarns may be created out of bread waste. Akram Zamani, a senior lecturer at the University of Boras in Sweden, is exploring the possibility of growing fungi on bread waste in bioreactors and using it, in two different processes, to create yarns and produce nonwoven textiles. The fungal fibers that researchers are using for the production of the textile are renewable and, in some cases, also show some antimicrobial properties, according to Zamani.
