Is it possible to create textiles from old bread? Akram Zamani, senior lecturer in resource recycling at the University of Borås, wants to find out. And she has already come a long way.
"We have seen that much of the food waste from grocery stores is from bread and therefore we wanted to see how we could turn it into a new product," says Akram Zamani.
Fungi - Waste - Bioreactors - Processes - Yarn
Filamentous fungi will be grown on bread waste in bioreactors, and will then be used in two different processes to create yarn and to produce nonwoven textiles (see fact box).
"When the bread has become a biomass of fungi, we remove the protein which in turn can be used as food or animal feed. We use the cell wall fibres that remain of the fungi partly to spin a yarn, and partly to create nonwoven fabrics."
