Brazilian resin supplier Brasco introduced an ethylene vinyl acetate copolymer extracted from sugar cane. The first application of this material was in a bioplastic plastic flip-flop product developed by Allbirds in San Francisco. Called Sugar Zeffer. This environmentally-friendly footwear company recently attracted the investment of Leonardo DiCaprio and Golden State Warriors basketball star Andre Iguodala.
The flip-flops based on bio-plastic materials use EVA foam extracted from sugar cane and other materials extracted and recycled from nature.
Allbirds calls the carbon-free foamed EVA a sweet foam (SweetFoam). This flip-flop is also made from a replaceable tape, made from recycled PET bottles, bio suede and castor oil-based thermoplastic polyurethane.
