Construction and Deconstruction waste

Construction & deconstruction (C & D) waste is a complex waste stream, made up of a wide variety of materials including concrete, plasterboard, wood, metal, brick, glass and soil.

Much of the C & D waste generated can be reduced, re-used and recovered, thus reducing the amount sent to landfill.

Waste generated from C & D activities is very dominant in this district at approximately 2,800 tonnes or 14% of the total waste sent to landfill per annum. Given the significant areas of land zoned for future residential growth in the district and the steady demand for housing sections and rental accommodation, it is likely that construction will continue to be a key industry in the future.

The QLDC Waste Minimisation and Management Plan 2018 acknowledges there is a high volume of construction and deconstruction waste being generated in our district. The actions council have committed to include;

  • Promote sustainable building practice that minimises waste and reduces resource use.
  • Review and provide upgrades to the layout and operation of resource recovery and waste disposal facilities to optimise resource recovery and improve capacity.
  • Provide resource recovery (and waste disposal) facilities that optimise separation of divertible material in Wanaka and Wakatipu.
  • Support and enable the development of construction and demolition material recovery where practicable.
  • Monitor the types and quantities of construction and demolition waste disposal.

A very useful resource for those involved in the construction and deconstruction industry is the Resource Efficiency in Building and Related Industries (REBRI) guidelines designed as a practical tool for use by architects and engineers to builders and recyclers. The guidelines are simple and cover a number of different topic areas, including development, design, construction and deconstruction. They also include information on the recovery of specific materials such as concrete, timber, plasterboard and steel.

The guidelines, as well as background information on the project can be found on the REBRI Website.
