Making the case for cardboard bottles, to replace glass
Apart from the introduction of twist-off caps, glass bottles have remained impervious to innovation for centuries-mainly because there's nothing wrong with them. Except they're fragile and awfully heavy. That's the insight behind Paperboy, a new brand of wine packaged in cardboard bottles. The container is made mostly of industrial paper waste that's 80 percent lighter than its glass cousin, so it takes less fuel to transport. Even with fuel prices dropping, gas and oil remain a huge expense for businesses. The packaging is molded from paper pulp (think of the material used in egg cartons) and lined with a plastic bladder, made by GreenBottle. Benefits include lighter weight, extra insulation keeping drinks cool longer, no risk of breaking, and cardboard is easier and more efficient to recycle than glass.
Beer manufacturer Carlsberg says they are also working on cardboard beer bottles, but unlike other cardboard bottles their design won't have a plastic bladder on the inside. Instead, the 100% biodegradable & recyclable cardboard will be treated with a coating on the inside to prevent beer from seeping through. They aim to release them in the next three years.
Transporting an item that's far below its target temperature is considerably cheaper... The train cars or truck trailers don't need active refrigeration system, as it'll take at least a couple days to thaw out, and should be at its destination long before then. The volume increases by a small amount, but eliminating the need for extra structure (like milk crates) should save even more space, and most importantly, weight.
