Green Milk. This is exciting! UK-based Greenbottle has recently announced their new milk container that promises a green solution to the waste produced by plastic milk bottles. The new bottle is made of a cardboard outer shell (made from pulped recycled cardboard using egg carton technoloy) and a biodegradeable plastic inner liner (made from corn starch). When the bottle is empty, the outer layer may be recycled and the inner liner will fully decompose in a landfill within six weeks... If not recycled, the whole bottle will compost at the landfill site. Greenbottle expects to be on shelves in the UK by the end of the year. They are also developing new ways of producing green bottles for other liquids. Via SwissMiss.
