Dispose of any unused skewers Did you know that the Bamboo plant is one of the fastest-growing plants on earth. Made from sustainable materials. These Skewers made from bamboo are more conscious than wooden or plastic skewers. Bamboo is a readily renewable resource. It is grass and has a very short growth to harvest period. Wooden skewers are often made from birch trees, which are not as rapidly renewable as bamboo. Plastic is, of course, not considered a readily renewable material.
