4. Part 1 Waste Minimisation and Recycling Collection Drivers in Palmerston North

5. Waste Minimisation Drivers in Palmerston North • Closure of Awapuni Landfill on 31st January 2007 and significant long term increase in waste disposal costs • Replacement of City Enterprises (old technology) collection fleet • Current manual collection using shopping bags leads to staff injuries and significant litter issues. • Waste and recycling services are core services of the Council and a significant weekly interface between Council and household. • Opening of Awapuni Recycling Centre and Long Term Partnership with Fullcircle to increase recycling in general • Adoption of Waste Minimisation Plan in November 2005 by Council • Over 40% of waste deposited into Awapuni was paper and plastics which are key materials in existing recycling collection • Separation of glass in kerbside collection

6. Waste Minimisation Plan - 2005 • The Palmerston North has a number of goals under its Waste Minimisation Plan 2005: • Strategy 1 –Maintain a comprehensive and effective rubbish collection and disposal service • Strategy 2 - Increase Recycling • Strategy 3 – Establish a Resource Recovery Facility with a community focus • Strategy 4 – Provide hazardous waste disposal facilities where possible • Strategy 5 – Provide environmental education • Strategy 6 – Adopt a disposer pays policy • Strategy 7 – Support a waste minimisation levy • Strategy 8 – Take a leadership in waste minimisation in the community

7. “Going Greener” Goals • Establish recycling industrial park powered by renewable energy. • Increase domestic recycling rate from 30% to 50% by 2012 • Implement Waste Minimisation Plan

8. Key Factors in Kerbside Recycling Collection There are a number of key factors in kerbside recycling collection: • Ease of use • Health and safety in collection • Collection volume, sort time and frequency • Cross contamination of material and source separation • Environmental factors – wind, rain, animal damage etc. • Household acceptance

9. Recycling Trends in New Zealand There are a number of trends in recycling in New Zealand: • Move away from waste disposal to resource recovery • Move to wheelie bins for collection – Auckland, Christchurch, Timaru South Taranaki etc • Long term Council contracts and partnerships with businesses • Service levels and costs have increased. • Recycling is an area where a Council can make a positive contribution to general environmental awareness.

10. Part 2 Recycling Collection Trial Andrew Slack – TBL Solutions(Contract to Palmerston North City Council)

11. Objectives of Kerbside Recycling Trial Strategy 2 of the WMP has the overall objective of increasing recycling in Palmerston North. One of the main factors driving recycling collection volumes is household acceptance of the kerbside collection system. Consequently the Council has undertaken a series of household acceptance trials. The objective is to select the best overall system for Palmerston North looking at a 10 year life span.

12. 3 Weeks 3 Weeks 3 Weeks 3 Weeks Group 1 RC CB WB Group 2 WB RC CB Group 3 CB WB RC Shopping Bags Structure of Recycling Trial The sample size was 350 households from a population of 27,500. This sample size is predicted to provide around a 5% margin of error. Each trial area was split into 3. Each trial was run for 12 weeks - 3 weeks on shopping bags (control period) and then 3 weeks on each of 3 new methods

13. Trial Areas in Palmerston North The following areas were included in the recycling trial: • Waterloo Crescent – 120 households • Ashhurst – 70 households • Maxwells Line – 160 households • Total Sample Size = 350 Households • The last trial week ended 7th December 2006

14. Recycling Collection Options – Glass Focus Glass Collection Options Single Stream Glass Collection Co-mingled Glass Collection Multi Compartment Bin Co-mingled Bin Split Bin Waste & Recycling Drop-off Bottle banks Separate Collection Kerbside Sorting GLASS IS DIFFERENT – IT DOES NOT LIKE COMPACTION OR EXCESSIVE HANDLING High Quality Glass – Mix, Compact and Break (30%) – Expensive Sorting – Low Quality Glass

15. Multi Criteria Analysis • Recycling Collection • Multi-Criteria Analysis • Environmental Factors • Community Factors • Economic Factors • Environmental Factors • Recycling Volumes • Glass Recovery Rates • Pest and /Wind Control • Community Factors • Convenience and ease of handling • Litter Control • Health and Safety(Collection and Household) • Economic Factors • Overall capital investment • On-going operating costs • Relative Collection Cost • Relative Sorting/Processing Cost • Glass Cross Contamination • System Wear and Tear • MORE THAN LOWEST SHORT TERM CONTRACT COST • The Palmerston North City Council has used a multi-criteria analysis to determine that a separate glass collection using bottle banks and/or bins is the best long term solution for glass collection.

16. Recycling Methods 4 kerbside recycling methods were trialed: • Shopping Bags (weekly) • 2 x Recycling Crates (weekly) • 240litre Standard Wheelie Bin • 240litre Castle (Multi Compartment) Wheelie Bin

17. Shopping Bags – Current System • Current system • Nearly phased out in NZ • Weekly manual system with health and safety issues • City Enterprises trucks need significant re-investment • Not much scope to increase volumes • Time for change?

18. Recycling Crates – Most Common in NZ • Most common system in New Zealand • Trend is to replace with commingled wheelie Bins • Weekly Collection • Volume is limited • Material is sorted on street with health and safety issues

19. Wheelie Bin – Rising Trend in NZ • Most common system worldwide • Move to wheelie bin in NZ – Auckland, Christchurch, Timaru etc • High penetration already in Palmerston North ($200 plus per week) • Flexible and automated pick-up • Fortnightly • Leads to increased participation and volumes due to convenience • Has problem of cross (particularly glass) contamination

20. Castle Bin – Prototype Invented in Palmerston North • Invented in Palmerston North by Glen Castle and PNCC recycling team • All advantages of standard wheelie bin system • Additional advantage of source separation and reduced post-processing costs

21. Questionnaire Format • Current recycling behavior? • Current wheelie bin use? • Do the new methods increase recycling? • System preference- user-friendly- mobility- tidiness • Comments

22. Trial ResultsHouseholds Strongly Prefer Wheelie Bins for Recycling • 90% households prefer either the Castle Bin or Standard Wheelie Bin for recycling

23. Results – Household Questionnaire • 50% said a new system would increase their recycling • 10% of participants were completely new recyclers • 30% used a wheelie bin in some way and 12% had a green waste bin only

24. Results – Household Questionnaire • There was very low support (2%) for the current shopping bag system and crate system (9%). • There was considerable enthusiasm for change • The householders wanted a tidy system protected from the environment • Households like convenience of wheelie bins • There were quite a few serious fans of the CastleBin

25. Trial Results Recycling volumes from alternative recycling systems are increased • 60% (Waterloo Crescent) to 80% (Maxwells Line) increase in recycling weights

26. Trial Results Relative sort time was 50% less for CastleBin

27. Trial Results Residual waste was 50% less for the CastleBin

28. Trial Results Recycling volumes from alternative recycling systems are increased • 60% (Waterloo Crescent) to 80% (Maxwells Line) increase in recycling weights

29. Castle Bin – Preferred Method(by Households) “The multi-bin was very easy to use and the street looked so much tidier on collection day. I went from two rubbish bags each week down to one which I assume meant I was recycling more” “The multi-bin was more user friendly than the wheelie bin…” “…the multi bin would probably make life easier as items are already separated” “…Our family really liked the separate compartments of the multi bin. It’s a winner!!” “I consider the multi bin to be the most economical as sorting will have generally been done by each household…” “Multi bin was by far the best. Its easier for the recycling people as well” “Loved the multi bin”

30. Shopping Bags New Recycling Collection System Dedicated Recyclers (30%) Possible Recyclers (40%) Unlikely and Never (30%) Castle Bin – Preferred Method(by Households) • The ease of use of MWB systems allows the recovery from the 40% possible recyclers to increase • Palmerston North has a goal to increase recycling to around 50% (compared to waste by weight) by 2012
