A process to extract the cellulose in cow manure to create a biodegradable textile and a method to use water, plant waste and solar energy to produce compostable nylon are in the running to receive €1m (£0.86m) from the H&M Foundation in its annual Global Change Awards.
The awards, now in their second year, were launched to help speed up the move towards a circular waste-free fashion industry. The public can decide how the prize pot is divided between the new shortlist of five finalists in an online vote, which is open until 2 April.
A method to use old denim to dye new denim is up against a process to use leftovers from winemaking to create fully vegetal leather and a new RFID thread that can be woven into garments to make the recycling process more efficient, as users can see what the garment is made of.
The awards received 2,883 entrants from 130 countries and the five most promising innovations were chosen by a panel that includes Rebecca Earley, professor in Sustainable Textile and Fashion Design at University of the Arts London, and Vikram Widge, head of climate and carbon finance at the World Bank Group.
The prize pot will be divided between the five finalists and they will also receive a trip to Stockholm to attend the grand award ceremony on 5 April and access to a one-year Innovation Accelerator, with coaching from the H&M Foundation, Accenture and KTH Royal Institute of Technology in Stockholm.
“I am convinced that by bringing people from different industries, with different backgrounds and perspectives together we can make a fundamental shift, speeding up the transition to a circular waste-free fashion industry,” said H&M chief executive Karl Johan Persson.
