A simple change to the design of the gallon milk jug, adopted by Wal-Mart and Costco, seems made for the times. The jugs are cheaper to ship and better for the environment, the milk is fresher when it arrives in stores, and it costs less.I like it. But I wonder, why does the milk need to be refrigerated at all? In other countries they sell milk in the same boxes that soy milk is sold in. They sit on the shelf without refrigeration and can last a lot longer without going bad. I am not quite sure what they have to do to the milk to allow it to be stored this way, but I would think that those boxes would be even better for the environment.
The company estimates this kind of shipping has cut labor by half and water use by 60 to 70 percent. More gallons fit on a truck and in Sam’s Club coolers, and no empty crates need to be picked up, reducing trips to each Sam’s Club store to two a week, from five — a big fuel savings. Also, Sam’s Club can now store 224 gallons of milk in its coolers, in the same space that used to hold 80.
And if they are redesigning the milk carton to minimize material usage, how about doing the same for the milk's partner: the cereal box? I wrote about this before, but I think they need to ditch the cardboard box, make the plastic a bit stronger and add a ziploc top to the plastic bag. Get on that next, Wal-Mart.
