BRANZ. Welcome to BRANZ



The construction and demolition (C&D) industry is one of the largest waste producing industries in New Zealand. C&D waste may represent up to 50% of all waste generated in New Zealand, 20% of all waste going to landfill and 80% of all waste going to cleanfill.

C&D waste is a complex waste stream, made up of a wide variety of materials including concrete, plasterboard, wood, steel, brick and glass. The sources of construction material waste include off-cuts, packaging, surplus materials, formwork, protection materials, damaged materials and rework.


Disposing of these materials to landfill not only means that they are not being recovered for further use but also that they then contribute to adverse environmental effects such as leaching of chemicals into soil and waterways as well as creating emissions of methane as construction and demolition waste breaks down and rots. Much C&D waste can be reduced, reused and recovered, dramatically decreasing the amount thrown away. Read about the Waste Minimisation Act and the waste disposal levy.

REBRI's main focus is on reducing the amount of building material wastes generated at C&D sites that would otherwise be sent to landfill. Find out more about how you can benefit by practising the three Rs of waste minimisation.

REBRI's goal is to improve resource efficiency in the building industry by providing the resources to:

  • reduce waste disposal costs
  • save money on raw materials
  • use materials more effectively
  • reduce the environmental impact from landfill disposal
  • maximise the amount of waste diverted from landfills and cleanfills
  • minimise contamination and damage
  • meet the requirements of the construction or demolition client and the recycling operator.
