Recycled Roads to Zero Waste Business Case

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

Bayside City Council Recycled 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

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

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

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

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

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

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’

‘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

‘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

‘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

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%

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
