According to this article Marks and Spencer is the worst supermarket for packaging waste. A study found that the supermarket is worse than Tesco, Sainsbury’s, Asda, Waitrose and Morrisons when it comes to packaging. Which? found that its packs of bacon, punnets for mushrooms and tubs for ice cream were all heavier than similar packaging from their rivals. Which? brought 27 own brand items from leading supermarkets including fresh and frozen food and washing up liquid and fizzy drinks. In each case the total packaging including the labels was weighed. The total weight of Marks and Spencer’s packaging was 415g, Sainsbury’s was the lightest at 369g and Tesco was just slightly more at 370g. Marks and Spencer said the study was flawed because it failed to take into account the amount of recycled material that was included in the packaging. They claim that in many cases their packaging may weigh more but is actually more environmentally friends because it is made from more recycled content.
