  1. Recycled Roads to Zero Waste Business Case

  2. Background • High % of waste starts with households and Councils collect it • Quarry resources are finite and running out in many areas • 2010-2012 • increasing VicRoads activity in using recycled materials in pavements: new standards (15-30% glass/brick) • increasing LG activity (4 mt pa G/B/C; Accord) • Governance Group > VR, SV, MAV, Eco-Buy, Swinburne, PSF, Councils • Specification testing (15% & 30%), workshops • Demonstration Trials: • Manningham (255m footpath, 22 tonnes glass @ 20%) • Port Phillip (100m footpath @30% glass) • Brimbank (375m road, 155 tonnes glass @15%) • Surf Coast (800m road, 900 tonnes recycled concrete) • Bayside

  3. Bayside City CouncilRecycled Roads to Zero Waste 2010/2011 Capital Works Program • $ 1.3M Residential Concrete Footpath Reconstruction Program • $ 600,000 Residential Asphalt Footpath Reconstruction Program • $ 550,000 Road Reconstruction Program • $ 400,000 Shopping Centre Footpath Reconstruction projects

  4. Footpath trial – Ludstone Street, Hampton • Project completed in April 2011 • 100m of concrete footpath reconstruction • 30% of <5mm diameter glass blend in Class 3 crushed concrete base • 7.6 tonnes of non-recyclable glass • Compacted very well under standard plate compaction

  5. Road reconstruction trial – Tramway Parade, Beaumaris • Project in construction, programmed for completion mid June 2011 • Project cost $355,000 • 270m length of road of which 36% was full depth pavement reconstruction • 15% of <5mm diameter glass blend in Class 3 crushed concrete sub-base • 41 tonnes of non-recyclable glass • Easily placed and specified compaction achieved as if using Class 3 crushed rock or concrete • High consistency in mix

  6. Bayside Observations Performance during construction • Easy to place and compact, high compaction achieved with standard processes • No noticeable difference in appearance (particularly road) • Contractors commented no issues with using this material Long term performance • Projects recently undertaken, long term durability and serviceability of pavement to be monitored and assessed

  7. Bayside Future plans • Trials were considered successful during construction • Long term performance to be assessed with review of other trial projects • Propose to use in future projects, pending costing and review of completed trial projects

  8. What next? • 2012: asked Councils to commit: low response • multi-functional: engineering, works, procurement, contracts (and contractor choice) • senior management not involved • timing issues • 2013: survey of 30 Councils • 97% use recycled if no cost difference and supply OK • New procurement guidelines evolving: VR/sustainability • Business case would be advantageous

  9. Business case • Reports of 70% increase in price of quarry materials in Sydney: sourced from 200km • Project Group: Sustainability Victoria (funding), MAV, VicRoads (netbalance) • Report: ‘Recycled materials in pavement construction’

  10. ‘Recycled materials in pavement construction’ Key points • Growing development threat to virgin supplies: over time will become more difficult to obtain • Recycled materials perform as well as virgin materials • Recycled materials can be cost competitive • Proximity to recycled source is key determinant • (up to 45km better; up to 85 km competitive) • Significant regional differences (see maps) • VicRoads specifications are very important

  11. ‘Recycled materials in pavement construction’ Benefits of using recycled materials • Reduced impact on the environment • Reduced waste to landfill • Reduced energy to produce pavement materials • Reduced land use conflict • Improved security of supply • Reduce risk to Council • Recycled materials can be cheaper

  12. ‘Recycled materials in pavement construction’ Recommendations for Councils: • Commit to use of recycled material which meets specifications and cost (Council choice) • Identify current availability of recycled material and potential barriers in your Council • Require contractors to report on their use of RM • Develop a strategy to increase use of recycled content: discuss with contractors • Include VicRoads spec 820 and 821 for road design

  13. Choice • Option to use recycled materials OR • Where there is supply at cost competitive rates, Council preference is for recycled materials in blends of 15%-30%

  14. Next steps • May 2014: MAV presentations to regional meetings of CEOs and Mayors. Seek support for: • LG strategic direction: increased use (preference) • VicRoads future direction • Good practice policy and contract management guidelines (give preference) • Local recycling to be maximised (work with local WMG) • Inclusion in Council plans
