Think food waste isn’t an issue? Well, picture the scene. You head to your local grocery store to do the weekly ‘big shop’. You browse the aisles, load a trolley, and then reload it on to the conveyer belt. You then repack every item into a worse-for-wear collection of canvas totes and reusable plastic bags – you actually remembered to bring them today, you’re feeling smug. Next, you transport the whole lot home.

When you make it to the front door, you do the usual, uncharacteristic display of hyper-mobility, reaching back, around and down to retrieve your keys from where should be, and then, when they typically are not where they should be, repeat the process in numerous other locations across your person and luggage, all while straining under the weight multiple carrier bags heaving with groceries.
