Sugars are the raw materials used in Brewed Protein™ polymer (powder) production. For polymer production in Thailand, Spiber procures sugar certified by Bonsucro, a global multi-stakeholder industry platform that promotes sustainable sugarcane production.
Although we strive to implement sustainable agriculture practices in our supply chains, we recognize that corn and sugarcane are ultimately food crops, and that some externalities associated with agriculture cannot be avoided. Accordingly, we are committed to shifting towards circular feedstocks in the future.
For example, cellulose contained in agricultural wastes such as sugarcane bagasse or corn stover, or discarded textiles made of “Biosphere Circular” fibers, can be broken down into nutrients that can be upcycled and fed to our microbes for production of Brewed Protein™ materials.
