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 –
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.

Waste and Deconstruction Management AUGUST 2014
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
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
Mapping Waste/ Deconstruction Streams august 2014
Mapping Reuse Streams in more Detail August 2014
Reuse AUGUST 2014
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
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
Reuse items - Insulation Removal of acoustic and thermal insulation. August 2014
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
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
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
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
Recycling AUGUST 2014
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
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
