IMAGINE:
You are done with a fruit juice plastic cup:

And you see the following recycling bins:
What would you do?
Office of Estate and Development, Office of Environmental Sustainability
Did you recycle correctly?
National Environment Agency (NEA) spokesman : throwing waste such as leftover food and drinks into the bins contaminates the recyclable materials and renders them non-recyclable.

How serious is contamination of recycling bins?
• NEA: About one-fifth of all waste deposited in recycling bins could not be recycled.

What do you think is the solution?
Singaporeans just don’t have the culture…. • Look at Japan, Germany….• Users just need to be educated …
Straits Times Discussion Board Replies to the article:
“Maybe a public campaign should be launched to educate the public on how to use the recyclable bins.….”

EDUCATION!EDUCATION!!EDUCATION!!!
BUT HOW TO EDUCATE?

Singapore national recycling vs. contamination?
Office of Estate and Development, Office of Environmental Sustainability
Recycling well labelled?
“Recycling bins are clearly labelled with the materials that can be placed in them.” Singapore Environment Coucil reply to the article
Office of Estate and Development, Office of Environmental Sustainability
Not really…
Another Straits Times Discussion Board Reply:“… I for one, was surprised to read from the papers that cardboards that hold food cannot be recycled, cos now I am guilty of throwing my pizza box into the recycle bin.”
Need to move beyond just labeling paper, plastic into labeling types of paper and plastic accepted.

NUS Recycling Story.
Our success and techniques
Office of Estate and Development, Office of Environmental Sustainability
Contamination in NUS (Before Nov 2008)
Office of Estate and Development, Office of Environmental Sustainability
Results in Jan/Feb 09
Level of contamination dropped drastically. Not perfect
Office of Estate and Development, Office of Environmental Sustainability
Vital Behaviours in tackling recycling contamination
1. At the point of throwing, help people to decide if it can be recycled
2. Give people an option to not throw into the recycling bin if it cannot be recycled.

VB1:Recyclable at the point of throwing ?
Common recycling bins in Singapore only label “Paper, plastic, cans”
Office of Estate and Development, Office of Environmental Sustainability

Recyclable at the point of throwing ?
Instructions right at the point of throwing
Office of Estate and Development, Office of Environmental Sustainability
Recyclable at the point of throwing ?• Expect Error from User = Specific about what
to throw– Reference:“Nudge – Improving Decisions about
Health, wealth and Happiness”• For prompts to be effective, they need to be
presented as close in time and space as possible to the targeted behaviour…– Reference: McKenzie-Mohr, D., & Smith, W. (1999).

Caveat
• Measures were already halfway through implementation by the time I join.
• Gave it a psychological basis or reason.• Isolate measures to “measure” effectiveness. • Applied psychological tendencies for future
measures.

Other lessons in bin design
Poka Yoke (Mistake Proofing) is the way to go
Office of Estate and Development, Office of Environmental Sustainability
Colour scheme of Trash bins
Green Trash Bin vs Green Bottles Recycling Bins– These 2 bins should not be placed side by side
Office of Estate and Development, Office of Environmental Sustainability
Solution: Different colour for trash bins• Colour scheme of Trash bins – Grey Bins
– Gradually replace current green trash bins with bluish grey ones over time
Office of Estate and Development, Office of Environmental Sustainability
Take the human error out of recycling bins display• Square recycling bins
– No need to remind housekeepers to have round recycling bins all facing front

Black labels to make up for vertical wordings
Office of Estate and Development, Office of Environmental Sustainability
Proposed new bins
• Horizontal words – ( move higher)
• Straight sides prevent turning
• Instructive description: – “Non recyclables” vs
“Others” or “Trash”– “Empty cans, Clean
Paper”

Posters to align bins for housekeepers

Almost blatant copying

People like to do what others do
Office of Estate and Development, Office of Environmental Sustainability
Still pathetic numbers
• Number of people on mailing list about 50,000
• About 4000 people have unsubscribed after offering .

Part 3 – Encouraging environmental friendly behaviour My personal thoughts from experience as volunteer, NGO and sadly no corporate
Office of Estate and Development, Office of Environmental Sustainability
They are just not educated/aware
• Point to the common people for not being educated.
• Try to convert everyone to a greenie.• Main tool: Information campaign.
– Sometimes for further education for the converts– Sometimes preaching to the converts.
Office of Estate and Development, Office of Environmental Sustainability
The world will be a boring place if everyone is greenieMy personal way to work:• Measure!• Use human and social psychology to facilitate
influence of human behaviours.
