Good question! We can talk about this for hours, but in short it means this: The BE O Bottle is a climate positive bottle. Here’s why: the BE O Bottle is made from sugar cane, a fast growing crop takes up a lot of CO2. So much that more net CO2 is absorbed than is emitted during production and shipping. After harvesting, the sugar cane is processed into cane sugar and a residual product is released. This residual flow is used to make bioplastic. In this way we also prevent parts of the plant from being wasted. Bonus for the climate: we plant a tree for every bottle sold through Trees for the Future.
