Reducing food waste


How much food do you throw out? The Uk’s waste and recycling advisory body, Wrap, estimated that 7.3m tonnes of household food waste was thrown away in 2015.

Shockingly, of that discarded food 4.4m tonnes was avoidable, i.e. it was edible at some stage (inedible food waste includes things like bones, orange and banana skins).

Much of this is discarded food is due to poor management of our fridges and lack of knowledge as to the best storage conditions and fridge zones for different types of foods. It leads to £13bn worth of wasted food across the country or £470 per household per year.

The environmental impact is even more concerning. This tonnage will generate 19m tonnes of greenhouse gases over its lifetime – a level of pollution that can be equated to a quarter of UK cars.

Sub-Zero prides itself on providing not just a refrigerator but a food preservation system, keeping fruits and vegetables fresh far longer than usual. Our fridges and freezers never share air which means the fridge air stays moist, ideal for longer storage.

What’s more, our NASA technology air filter scrubs the air of mould, viruses, bacteria and the ethylene gas that hastens spoilage. Yes, this Granny Smith apple really has been in one of the fridges on our showroom since June 2017 and we took the picture above just last week.

Every fridge and freezer comes with food preservation cards which are stored within the appliance and detail where and for how long to store fresh and frozen foods. Did you know that blueberries will keep 10-18 days in Sub-Zero refrigeration drawers, but a Honeydew melon is best stored on the shelves for 3-4 weeks where the humidity level is higher, for optimum results?

Tips for reducing food waste

  • Make a flexible menu plan for the week ahead
  • Use the menu plan as the basis for your shopping list
  • Always check the contents of your fridge before going shopping, so there’s no duplication of ingredients
  • Eat before going to the supermarket – you’re less likely to buy more than you need
  • Habitually look at ‘Use by’ dates when buying and when deciding what to cook and eat
  • Transfer foods to the freezer if you aren’t going to be able to eat them before their 'Use by'date
  • Store foods in the correct section, e.g. dairy compartment, salad drawer, to optimise freshness
  • Don’t overload the fridge or keep the door open for too long.

Of course, a great deal of food is also wasted by supermarkets and Tesco is preparing to become the only UK retailer to stop wasting food suitable for human consumption. It has promised that none of its UK stores will waste produce by March 2018.
