  9. What the experts say.. Stevensons Test results – Stevenson Laboratory Ltd completed a full suite of NZTA M4 Basecourse specification tests finding ….. “ The Wards RCC AP40 aggregate at the density tested is above average performance for the dry/drained test and well above average performance for the saturated/undrained test (note: all unbound aggregates perform poorly in the saturated except the Wards RCC AP40 showed exceptional performance ).” WME Magazine 2009 Edition –

  10. Where to from here? Council have sanctioned research into this topic having Synergine head up the project of investigating whether RCC could be used in roading on behalf of Auckland Transport. The Road to recovery article after research provides RCC; Environmentally lowers a carbon foot print on greenhouse emissions Is highly cost effective option – 22 years life of Virgin rock vs 447 years life RCC – 20% cheaper giving customers more material for the tonne “The impact is overall sustainability to a large infrastructure project.” We need this, we need to encourage initiatives that provide better options for recycling in our industry of building infrastructure both in roading and other large projects.

  11. Auckland Council Workplace Strategy Environmental Management at 135 Albert Street August 2014

  12. Overview • 135 Albert Street - key deliverables • Fletcher’s commitment • Waste / deconstruction management: waste not want not • Reuse and recycling examples • Waste reporting AUGUST 2014

  13. Key Deliverables at 135 Albert Street • The sustainable redevelopment of 135 Albert Street • Deliver a 5 Star Green Star NZ Interior 2009 rating • A target of 90% landfill diversion • Fostering an ‘Integrated Whole Building Design Process’ • Deliver a NABERS NZ rating for the building AUGUST 2014

  14. Fletcher’s Overarching Commitment  Committed to working together to protect the environment.  Reducing the impacts associated with our manufacturing, construction and extraction operations.  Reducing the impacts associated with the distribution and use of our building materials. AUG 2014

  15. Waste and Deconstruction Management AUGUST 2014

  16. Sending out the message - Waste Management • In partnership with Auckland Council we set out to redefine what ‘waste’ meant to the project team. Focusing on deconstruction • We understood the need to provide a clear and fundamental message. • Throughout pre-start meetings, toolbox talks, review meetings we emphasised the basic principle of waste hierarchy. august 2013

  17. Adopting a Waste Hierarchy As we engaged staff and communicated the hierarchy of waste, we developed detailed systems as part of our Environmental Management Plan. august 2013

  18. Mapping Waste/ Deconstruction Streams august 2014

  19. Mapping Reuse Streams in more Detail August 2014

  20. Reuse AUGUST 2014

  21. Reuse items to the Community  In collaboration with Auckland Council and Ecomatters, 29 ton of deconstructed items such as thermal insulation, book shelves, cupboards, furniture, hot water cylinders were transported to Henderson Waste Transfer  Inventory was created and items provided at a very small cost to the community  Example: A Kaitaia community group who purchased a large amount of furniture for their offices August 2014

  22. Reuse items for 135 - Existing luminaires 2443 light fittings = 3.9 ton of recyclable material Made up of = diffusers, control gear, wiring, plastic & tubes 4 ton of reuse i.e. steel casings august 2014

  23. Reuse items - Insulation Removal of acoustic and thermal insulation. August 2014

  24. Reuse items - Insulation As a means of working leaner, we sorted, bagged and weighed the insulation whereby creating a more attractive prospect for ‘reuse’. august 2014

  25. Reuse items - Glass Partitions  As part of our deconstruction we removed the existing glass partitions.  Safely stored on B4 ready for reuse within 135 Albert Street.  The finished reuse product as glass mark-up panels as shown above. August 2014

  26. Reuse items - Lundia Shelving  As part of our deconstruction we removed existing Lundia Shelving.  Safely dismantled and stored on B4 ready for reuse within 135 Albert Street.  The finished reuse product reassembled, cleaned and installed as shown above.  8.631 ton of Lundia Shelving. august 2014

  27. Reuse items - Roller Blinds  As part of our deconstruction we removed the existing roller blinds.  The finished reuse product reassembled, cleaned and installed as shown above.  1.88 ton of reuse blinds. August 2014

  28. Recycling AUGUST 2014

  29. Recycling of Ceiling Tiles  As part of our deconstruction we removed all of the existing ceiling tiles.  The ceiling tiles where then transported to Envirofert for recycling.  Currently at 109.3 ton of ceiling tiles. august 2014

  30. Recycling of Ceiling Tiles New plant 80:20 ratio With new plant the recyclable recovery rate improved to 80:20 e.g. 80% recycling 20% landfill. august 2014
