When I arrived in Buenos Aires in Feb 2009 I was surprised to see the majority of milk being sold in bags. I bought a tetrapak because I wasn’t sure what to do with the bag, although I knew that sachets like this typically use 80 to 90% less material than alternative forms of packaging. After a while my friend gave me a milk jug – ah! So the Argentinians use a durable jug and lightweight throw-away milk pack, the goal being saving money. Bags are cheaper than tetrapaks, so everyone buys them.
During a recent visit to the UK, I noticed that Sainsbury’s have started doing the same. In July of last year, Sainsbury’s pledged to cut the weight of packaging they sell by a third by 2015. Milk in bags will help them achieve this. Many other major supermarkets have set similar targets as part of their on-going ‘green wars’.
So, it seems, bags of milk are cheaper AND greener and these two countries have arrived at the same solution from two different directions. I think we’re going to see more and more of this convergence.
The third image is the ‘Calf and Half’ milk jug designed by Liz Goulet of Fred Studio which would be a pretty cool thing to decant into. Or perhaps better would be the Seletti milk jug designed to look like a tetrapack. Or maybe you already have a jug.
