The Food We Waste

In the UK we throw away 6.7 million tonnes of food every year, roughly a third of everything we buy. Most of this avoidable and could have been eaten if only we had planned, stored and managed it better. Less than a fifth is truly unavoidable – things like bones, cores and peelings.

Nearly one quarter of the 4.1 million tonnes of avoidable food waste is thrown away whole, untouched or unopened. Of this, at least 340,000 tonnes is still in date when thrown away. A further 1.2 million tonnes is simply left on our plates. This all adds up to a story of staggering wastefulness.

The report of the ground-breaking study that provides, for the first time, reliable information about the nature, amount and origin of food waste produced by UK households. The purpose of the report is to assist WRAP, government, retailers and the food industry to develop policies, advice, tips and tools to help us all reduce the amount of good food we buy but don’t eat.

Every day we throw away:

• 5.1 million whole potatoes
• 4.4 million whole apples
• 2.8 million whole tomatoes
• 7 million whole slices of bread
• 1.3 million unopened yoghurts and yoghurt drinks
• 1.2 million sausages
• 1 million slices of ham
• 0.7 million whole eggs
• 0.7 million whole bars of chocolate and unwrapped sweets
• 0.3 million unopened meat-based ready meals or takeaways
• 0.3 million unopened packets of crisps

All this wasted food is costly; in the UK we spend £10.2 billion every year buying and then throwing away good food. That works out at £420 for the average UK household. And for households with children it’s even more - £610 a year.

Local councils then spend another £1 billion collecting our food waste and sending most of it to landfill.

Food waste is also harmful to the environment. The food we throw away needlessly is responsible for the equivalent of 18 million tonnes of carbon dioxide emissions every year – that’s the same as the CO2 emitted by one in every five cars on UK roads. It’s not just the methane that’s released when the food goes to landfill that’s the problem, but also the energy spent producing, storing and transporting the food to us. Put another way, every tonne of food we throw away needlessly is responsible for 4.5 tonnes of CO2 equivalent emissions.

Food waste is an enormous challenge, not least because most of us don’t yet recognise the amount we all produce. But it is also a massive opportunity – to reduce waste, save money and minimise our impact on the environment.

We can reduce our food waste by taking simple free measures;

• Sort your cupboards
  
  • Arrange your cupboards, fridge and freezer to ensure that you have no food which is past its "use by" date.
  • Arrange food by type and place in date order with the most recent date to the front.
  • You may find that you can survive without visiting the supermarket for a few weeks.
• Plan your meals
  
  • Plan in advance meals over a week, you do not need to physically write this down but mentally take note.
  • Be creative you can create some wonderful combinations from the scraps you find in a fridge.
• Plan your purchases
  
  • Plan in advance what you need from the supermarket.
  • Don't be tempted to buy items through special offers which you may not need or use within the use by date.
  • Do not buy items which you have multiples already.
    
  • Only purchase enough pershiables which you can use within the dates.
  • Do not go to the supermarket with "Eyes Bigger than Your Belly" and an empty stomach.
    
• Composting
  
  • Any food which you do not consume by the use by date can be added to a compost heap.
  • Packaged foods excessively past their best before date can be removed from their packaging and composted and the packaging recycled.
    
  • Compost bins can be purchased relatively cheaply and some local councils offer free compost bins.

The study, believed to be the first of its kind anywhere in the world, consisted of a detailed survey of households and a physical analysis of their rubbish. It was designed to not only quantify the amounts and types of food waste being produced but to make links between this and the attitudes displayed by and disposal options available to the household.

A representative sample of 2,715 households in England and Wales was interviewed in July-October 2007, and several weeks later the waste from 2,138 of them was collected and analysed. These households were all within a group of 11 geographically representative local authority areas chosen to reflect a range of collection systems, including food waste collections. Participants were asked about their perceptions on a range of issues concerning household waste, focusing on food.

Households were informed that as part of the research their waste would be collected for analysis, asked for their signed consent, and given the chance to opt out if they chose. Bin analysis was only carried out with those who consented, which was the vast majority. A period of four weeks then elapsed before their waste was collected for analysis to ensure that any temporary behaviour changes as a result of increased awareness of the research had dissipated.

We used industry standard waste analysis techniques to sort and categorise the waste. We then defined the food waste as either: avoidable food waste – where the food has been thrown away because it is no longer wanted or has been allowed to go past its best. Examples include an
apple or half a pack of cheese; possibly avoidable food waste – where the food waste could possibly have been avoided but incorporates food items that can be eaten but that many choose not to. Examples include bread crusts and potato skins; and unavoidable food waste – where the food waste results from food preparation and includes foods such as meat bones and hard vegetable or fruit peelings such as melon rind.

After analysis, the waste was disposed of safely on the same day, with the assistance of the local authority or their contractor. Where facilities existed – in just under half the authorities involved – the food waste was sent for composting. The result of this detailed survey and physical analysis is a comprehensive analysis of how much food we throw away, who is throwing it away, and what it costs society.
