The document addresses the significant issue of food waste in the UK, highlighting that nearly a fifth of food waste is avoidable, with each person discarding about 70kg of it annually. It discusses the environmental, financial, and social implications of food waste, while emphasizing the need for behavior change through design and awareness initiatives.

5. Food Waste in the UK

6. Nearly a fifth is avoidable

7. Why?

8. 70kg per person per year

9. Direct costs...

10. ... and indirect costs
● Financial
○ Electricity: fridge/freezer
○ Petrol: supermarket
○ Council tax: refuse collection
● Environmental
○ Pollution (air, water, land): agriculture, processing,
transport, retail, disposal
○ Biodiversity: land use
● Social
○ Food security: imports
○ Malnourishment: higher prices and opportunity costs

11. Lack of awareness
"We don’t realise how much we
throw away. Even householders who
are adamant that their household
wastes no food at all are throwing away
88kg of avoidable food a year."

12. A familiar story
But I don't like crusts!
Hmm...
USE BY:
11-JUN-13
Eugh! Mouldy potatoes!

13. An unfamiliar story...

14. The Rise and Fall
of
Billy the Banana

21. 15,000 bananas just like Billy are thrown
away by UK families every day.
Please...
THINK BEFORE YOU THROW

25. Behaviour change
"Behavioral economics ... studies the effects of social, cognitive, and emotional factors on the economic
decisions of individuals and institutions". [Source: Wikipedia]

26. We are influenced by:
Messenger - who tells us
Incentives - rules-of-thumb
Norms - what others do
Defaults - go with the flow
Salience - what's novel & relevant
Priming - subconscious cues
Affect - emotional associations
Commitment - public promises
Ego - feeling good about ourself

27. Design
"Today one the leading-edge areas in which
design can influence behaviour change is in
relation to safeguarding the environment ...
giving home-owners immediate and
understandable visual feedback".
Jeremy Myerson, Helen Hamlyn Professor of
Design, Royal College of Art
[Source: MINDSPACE 02 March 2010]

28. We are influenced by:
Messenger Incentives
Norms - UK average
Defaults
Salience - twinkly lights
Priming
Affect - smiley faces
Commitment
Ego

29. Waste separation

30. Maths
Use a simple number to tell a complex story of
global economics, politics and human values:
if > 0 : wasting more than per capita average
Notes:
● 0.61 = 61% ["most of the food we throw away (4.1 million tonnes or 61%) is avoidable"]
● 192 = 70,000g / 365 = 192 grammes ["on average, every one of us throws away 70kg of
avoidable food a year"]
