Brazilian resin supplier Brasco introduced an ethylene vinyl acetate (EVA plastic) copolymer extracted from sugar cane. The first application of this material was in a biomass plastic flip-flop product developed by Allbirds in San Francisco, called the Sugar Zeffer. The 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 refers to the carbon-free foamed EVA as SweetFoam. This flip-flop also features a replaceable strap made from recycled PET bottles, bio suede and castor oil-based thermoplastic polyurethane.
