Some supermarkets offer bags for life we can use time and time again, while others use biodegradable bags we can throw away.
Somerfield's bio-degradable bags enabled me to throw them away with no feeling of guilt. I even used to collect kitchen compost in them and, as they were bio-degradable, chuck them on the compost heap.
The most bizarre place to find a Somerfield plastic bag was in China. A department store was using them as their own: when I visited the country in 2001. The exotic blue and white bags were a fashionable item in the city of Nanchang. How such a vast supply of a UK supermarket's bags had got there is a mystery.
Somerfield stores have now disappeared, but their bags live on: real bags for life.
I planted a hedge ten years ago. When cutting it back today I discovered several plastic bags. Environmental friendly bags, according to their fresh blue print. Not even the ink had bio-degraded after months in a compost heap followed by ten years under a hedge.
Don't believe everything you read: especially on a plastic bag.
