Could dead leaves turn into green gold?

Imagine a world where we could make paper, cardboard and packaging without cutting down a single tree. Today, that dream is becoming reality. The start-up Releaf Paper turns fallen leaves into value. It was founded by a Ukrainian scientist, who moved to France before Russia's full-scale invasion to set up a pilot factory in the suburbs of Paris. Production only started a few months ago, with promises of greener goods and a circular economy. FRANCE 24's Aurore Cloé Dupuis, Alexandra Renard and Jonathan Walsh report.
