When buying fresh vegetables, ask for them without any plastic packaging. Its only use is to keep your produce unspoiled from the shop to your home, where it will go straight into the bin. You can take reusable bags shopping, pack your produce carefully and there’s no need for disposable packaging!
When you come home, in order to keep things fresh you can wrap the cut ends of your produce in a damp cloth, wrapped snugly around it and then leave it in your fridge. It will keep for a week like this!
