QUALITATIVE INTERVIEWS
KEY FINDINGS
YOUR LOGO
• Householders understood participation was optional
• Information was clearly communicated
• Education materials were memorable and clear
• Bins were delivered without problem
• How to use the bins and service seemed clear
• Householders had positive engagements with WWA and bin delivery staff
TRIAL SERVICE FEEDBACK
YOUR LOGO
• Successful message delivery:
‘organics waste collection is to reduce landfill’
• High awareness of neighbour and street activity, so need to develop a critical mass of participation to foster social norms (similar to kerbside recycling)
KEY LEARNINGS
YOUR LOGO
• Participants: willing to give it a go, depending on the perceived effort required
• Non-participants tended either to be:
o people in ‘stressed’ circumstances
o already felt ‘not contributing to landfill’, e.g. composting
o lower motivation to change – why bother?
o Physical barriers
• Managing smells and noxious products such as nappies were main concerns for fortnightly collection of rubbish.
KEY LEARNINGS
YOUR LOGO
• 23 litre kerbside bin
• 6 litre caddy
• Compostable liners
• Weekly organics collection
• 2 weekly rubbish collection • Trial now extending beyond four months
KEY LEARNINGS
YOUR LOGO
• Organics trial will continue until service roll-out 2016/17
• New trials:
• Expand organics trial on North Shore
• Trials in South Auckland
• Edmund Hillary School
• Manurewa - ‘challenging’ street
• Multi-unit dwelling trial 2015

YOUR LOGO
3 options for consideration:
• Automation
• Semi automation
• Manual handling
COLLECTION OPTIONS
YOUR LOGO
COUNCIL’S APPROACH
• Preferred collection methodology in
development
• Work in progress for Council review include:
• International best practice review – scan of what’s
happening elsewhere
• H&S review - subject matter expert engaged
• Ergonomic review - subject matter expert engaged
• Internal workshops – includes front line staff
• Utilising Industry expertise – via WasteMinz
