•  Why did the change to Transwaste ownership occur?

    Transpacific (TPI) was invited by Civil Defence to become part of a joint venture with other recycling companies to establish the Burwood recycling operation. TPI was happy to take on such a potentially very difficult project as part of a joint venture partnership.

    In the event, the other joint venture partners found the project too economically challenging and withdrew from the joint venture. TPI had always been comfortable with the project being a joint venture, but were clear that without suitable joint venture partners, TPI would not proceed.

    TPI commenced a search for replacement joint venture partners who had an interest in the project being successful. After canvassing industries, the only potential partners with sufficient stake in the success of the project were the Canterbury local authorities, who understood that if the project did not proceed, it would have to be picked up by the Councils anyway, as the project is vital to the earthquake recovery in Canterbury.

    As TPI was already in a very successful joint venture with the Canterbury Councils, Transwaste Canterbury Ltd, it made perfect sense to use this existing joint venture to manage the Burwood project.

  • What are the economic costs and benefits of the scheme - and to whom?

    The economics of the project are modest. The more valuable materials able to be recycled are now being recovered during demolition, rather than at the Burwood recycling plant, as had been the original vision of Civil Defence.

    Under the joint venture, any loss or profit from the project would be shared equally between TPI and the five Canterbury Councils.

  • What are the environmental outcomes? Exactly how much material will be left at Burwood? How much and what will be recovered and where will it go?

    One of the difficult aspects of this project is that nothing is certain about volumes of material the site will receive, as most clean concrete and rubble is going into Lyttelton harbour, and most other demolition sites are removing metals and any other recyclable material, before sending just the residual detritus to Burwood.

    Estimates of potential demolition waste to Burwood range from 300,000 to 700,000 tonnes, with recent trends suggesting it will be towards the lower end of that range.

    The amount to be left at Burwood in the new landfill cell to be constructed will depend upon how much of the material received can be recovered and reused elsewhere.

    Environment Canterbury has been working constructively with CERA, the Christchurch City Council and BRRP throughout to ensure that waste would be managed as close as possible to the source with the least environmental impact.

    It is essential that the coastal aquifer, which is part of Christchurch city's groundwater zone, is well protected by consent operating conditions, which would be monitored by the regional council. A properly designed and engineered liner inserted between the landfill and the shallowest aquifer and upwards hydraulic pressure, combined with the fact only inert and low-risk materials would be disposed of at Burwood Resource Recovery Park, will provide that protection.

  • How much material has been received to date- and who now owns it?

    Around 300,000 tonnes of residual demolition material is in the existing stockpile. It is owned by Burwood Resource Recover Park Limited (BRRP).

  • Where do responsibilities lie for future potential liabilities?

    In relation to the sorting operations, and new Burwood cell, the liabilities are with BRRP. All operators who currently have sorting facilities (and ultimately the land owners if the operators don't carry out their responsibilities to clear the sites) have similar liabilities.

  • Who is paying what for the establishment of the sorting facility and its operation and what will the ownership structure be?

    BRRP will fund the establishment and operation of the sorting plant and will own the plant.

  • Who will own the $9.5M worth of assets during the operation and at its completion?


  • What level of sorting and / or processing is proposed?
