YOUR LOGO
WMMP
• Regional consistency
• User pays refuse
• Enhanced recycling
• Urban food waste collections
• Resource recovery network
• Inorganic collections
• Waste minimisation programmes
• Targeted community engagement
• Communications
YOUR LOGO
WHY FOOD WASTE ONLY?
• Largest proportion of waste stream
• 130,000 t/yr to landfill (~90,000 t/yr
in kerbside refuse)
• Mature green waste industry
• Mixed collection adds volume/cost
YOUR LOGO
WHY A PILOT TRIAL?
• Test before roll out to region
• Manage risk – clarify volumes for processing
• System design – participation, set out rates,
contamination
• Assess resident behaviours
• Determine customer satisfaction, barriers, benefits
• Identify improvements to build on best practice
YOUR LOGO
TRIAL DESIGN – KEY CONSIDERATIONS
• Simple and easy to use
• More attractive than refuse bin - reduce ‘yuck
factor’
• Pay As You Throw (PAYT)
• Best practice
• Represent Auckland demographics - ethnicity,
income and household type

YOUR LOGOQUALITATIVE INTERVIEWS
KEY FINDINGS
YOUR LOGOTRIAL SERVICE FEEDBACK
• 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
YOUR LOGOKEY LEARNINGS
• 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)
YOUR LOGOKEY LEARNINGS
• 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.
YOUR LOGOKEY LEARNINGS
• 23 litre kerbside bin
• 6 litre caddy
• Compostable liners
• Weekly organics collection
• 2 weekly rubbish collection
• Trial now extending beyond four months
YOUR LOGOWHERE TO FROM HERE?
• 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 LOGOYOUR LOGO
COMMUNITY ENGAGEMENT
• Focus on community engagement and education
• Working with community partners and networks
• Approach to foster buy-in and service uptake by low
socio-economic communities

YOUR LOGOORGANIC COLLECTIONS: METHODOLOGY OPTIONS.
WARWICK JAINE, OPERATIONS MANAGER
YOUR LOGOCOUNCIL’S STRATEGY TO SAFETY
• Council must be satisfied that all H&S risks
associated with any collection system and
design, have been fully assessed.
YOUR LOGOCOLLECTION OPTIONS
3 options for consideration:
• Automation
• Semi automation
• Manual handling
YOUR LOGOCOUNCIL’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
YOUR LOGOKEY CONSIDERATIONS
Level of acceptance by householders and
operators.
Storage space on property - bin size
Householder perceptions and attitudes
Contamination management - Bylaws
YOUR LOGOBIN OPTIONS
• 60 ltr MFB
• 23-25 ltr
YOUR LOGOKEY CONSIDERATIONS
Maximising participation
Manual handling - H&S views
Cost of service – total cost of ownership
Bin costs vs collection costs vs processing
YOUR LOGOAUTOMATIC HANDLING
kerbside bin (60 to 80 litre) modified with
an internal false floor to reduce capacity
to 23-25L)
Bin mechanically picked up by collection
operator and emptied into the vehicle .
YOUR LOGOSEMI-AUTOMATIC HANDLING
Kerbside bin capacity = 23-25 litres
Bin is picked up by the operator (operator
is external from the vehicle to handle the
bin) and placed into a larger bin (≥ 240
litres) or similar.
When full, this is mechanically emptied
into the collection vehicle
YOUR LOGOMANUAL HANDLING
Kerbside bin capacity = 23-25 litres
Bin is picked up by the operator and
placed directly into the collection vehicle
Operator is external from the vehicle to
handle the bin empty
YOUR LOGOKERBSIDE COLLECTION – COUNCILS
CURRENT POSITION
23 to 25 litre kerbside container
(ergonomically design)
