I am chair of the all-party parliamentary group on food waste. I acknowledge that some packaging helps to preserve food’s shelf life, but in many cases it is unnecessary. It has been brought to my attention that in supermarkets it is often cheaper to buy the packaged-up produce, because it is on special offer, so buying a couple of avocados in a package might be cheaper than buying them loose. It seems ludicrous, but if people have to pay extra for loose produce, I understand why they feel inclined to buy the packaged produce, even if they are trying to avoid plastic waste. Do supermarkets not have a role to play in changing that?
