Lots of UK supermarkets have recently started selling chopped tomatoes in Tetra Paks, rather than the tins they were always in. My first thought was that this was environmentally bad - given recycling facilities for Tetra Paks are much harder to come by, compared to tins.
However, there are also obvious positives:
- I imagine far more energy is needed to form/recycle a metal can, than a Tetra Pak.
- Tetra Paks tessellate far more neatly - less space between cans on a lorry = less lorries.
- Tetra Paks would be lighter than cans, therefore, again, less fuel used to transport.
Overall, would this appear to be an environmental decision from the supermarkets, or a financial one, for the supermarkets margins? (I'd imagine Tetra Paks are definitely cheaper to produce than cans.)
