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.

Adopting a Waste Hierarchy

august 2013

As we engaged staff and communicated

the hierarchy of waste, we developed

detailed systems as part of our

Environmental Management Plan.

Reuse

AUGUST 2014

Reuse items to the Community

August 2014

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

Reuse items for 135 - Existing luminaires

august 2014

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

Reuse items - Insulation

August 2014

Removal of acoustic and thermal insulation.

Reuse items - Insulation

august 2014

As a means of working leaner, we sorted, bagged and weighed the

insulation whereby creating a more attractive prospect for ‘reuse’.

Reuse items - Glass Partitions

August 2014

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.

Reuse items - Lundia Shelving

august 2014

As part of our deconstruction we removed existing Lundia Shelving.

Safely dismantled and stored on B4 ready for reuse within 135 Albert Street.

Recycling of Ceiling Tiles

august 2014

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.

Recycling of Ceiling Tiles

august 2014

With new plant the recyclable recovery rate improved to 80:20 e.g. 80% recycling 20% landfill.

New plant 80:20 ratio
