wondering : what could be a better material for things that wears like tires for bikes and soles for shoes that would not use/diffuse (micro)plastics ?

could those "leather" alternatives work ? some biomaterial with discarded fibers from food processing ? woven fibers with natural resin ? any clues ?

(thinking about that process while rethinking every piece of our #veli #lightVehicule toward more earth friendly process of fabrication ) #bike #recycling ##biocompatible
