food waste hero
DESCRIPTION
Food Waste Hero is a project to raise awareness of food waste and initiate change through behavioural economics, storytelling, design and technology. It features a Raspberry Pi internet-of-things device to weigh kitchen food waste bins and show how households are doing compared to the UK average. This presentation was given to NIAB (National Institute of Agricultural Botany) in June 2013 in Cambridge UK.TRANSCRIPT

Food Waste in the UK
Nearly a fifth is avoidable
Why?
70kg per person per year
Direct costs...
... 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
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."
A familiar storyBut I don't like crusts!
Eugh! Mouldy potatoes!

An unfamiliar story...
The Rise and Fall of
Billy the Banana
15,000 bananas just like Billy are thrown away by UK families every day.
Please...
THINK BEFORE YOU THROW

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

Waste separation
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"]

Potential Partners
● WRAP: Waste & Resources Action Programme
● Ellen MacArthur Foundation: Circular Economy
● Schools: storytelling, D&T, computer science, art, biology, history ...etc
● Local government: Landfill Tax, pay-as-you-throw, national and international targets
● CSR: Tesco, M&S, Pret-a-Manger
Questions
● Purpose of food?○ nutrition○ social bonds ("quality time")○ dieting○ fads (superfoods/celebrity chefs)○ 5-a-day
● Not segmenting by number in household - problem of the "mean" (report fig. 163)
● Simplify for schools: spreadsheet + kitchen scales
Design challenges
Reality is messy
