The following materials can usually be sorted and recycled. For some sorted materials, waste collectors will remove filled skips and containers at no charge and may take co-mingled materials for off-site separation for a small fee.

Asphalt

  • Sort by type for milling and recycling.
  • Break up and reuse on site for temporary road construction or hardfill.

Brick

  • Whole bricks set with lime-based mortar - reuse in fences, landscaping and construction.
  • Whole bricks set with concrete - recycle.
  • Broken bricks - crush for use as landscape over, sub-base material or hardfill.

Cardboard and paper

  • Separate for recycling into new products.

Concrete and masonry

  • Use crushed concrete aggregate anywhere natural aggregate is currently used, including:
    • loose on driveways, for unsealed hard stand and in landscaping
    • as a base course for footpaths, roading, driveways and other asphalted or sealed surfaces
    • as a base course under building foundations in civil works such as stopbanks, earth bunds, soakage pits, drainage channels and beds for pipe works and cabling.
  • Cast-in-place and precast concrete - recycle or reuse for stabilising slopes, river banks and foreshores.
  • Concrete/masonry block not filled with concrete - reuse.
  • Concrete/masonry block filled with concrete - recycle.
  • Paving stones - reuse/recycle.
  • Tiles/slates - reuse/recycle.
  • Pipes, masonry service structures - reuse/recycle.

Glass

  • Glass, bottles and jars - recycle.
  • Double glazing units in good condition - reuse.
  • Double glazing (failed) - recycle.

Hazardous materials

  • Paints, solvents and other hazardous fluids.
  • Materials with lead-based finishes.

In the interests of health and safety, you should check the removal and disposal requirements of hazardous materials with your city or district council. Some manufacturers have take-back schemes for paint (such as the PaintWise scheme from Resene). 

Metal

  • Aluminium (soffit, cladding, cappings, flashing) - reuse or recycle.
  • Cast iron - recycle.
  • Chain link fencing - reuse or recycle.
  • Copper (flashing, wiring, plumbing) - reuse or recycle.
  • Drink and food cans - recycle.
  • Interior steel wall studs - recycle.
  • Lead - (piping, plumbing, flashing) recycle.
  • Reinforcing steel (rebar) - recycle (usually embedded in concrete so not reusable).
  • Steel and zinc (roofing, cladding flashing) - reuse/recycle.
  • Structural steel - reuse (including I-beams, square tubing, pipe and channel steel), otherwise recycle.
  • Miscellaneous steel - reuse/recycle.
  • Miscellaneous other metals - reuse/recycle.

Plastics

  • Packaging, pipe off-cuts, expanded polystyrene block off-cuts, buckets - separate by type (all are labelled) for recycling into new plastics.

Plasterboard

Once recycled plasterboard is crushed, the gypsum can be sold as a powder (with or without the paper) or moulded into pellets. Gypsum can be:

  • used as soil and compost conditioner and for other agricultural applications
  • composted with other green waste
  • combined with sawdust and wood shavings for animal bedding, because it absorbs moisture
  • reused in the plasterboard manufacturing process (depending on the manufacturer's specifications for gypsum quality)
  • used in the cement-making process (virgin gypsum is currently added to the ‘clinker' to control the setting time
  • used for drying sludge from municipal and industrial wastewater treatment plants because of its moisture-absorbing characteristics
  • used to settle dirt and clay materials in turbid water
  • used to absorb grease spills.

Soil

  • Retain and replaced after construction so that existing nutrients can be returned back to the site.

Timber

  • Includes treated and untreated timber, hardwood, native timber, demolition, off-cuts, framing, cladding, interior fittings and linings, engineered timber products (MDF, fibre board, particle board, etc), joinery, panels, lengths, pallets and packaging.
  • Untreated timber - reuse, separate all types of untreated timber without finishings (paint, varnish etc) that is not good enough for salvage (under 600mm or damaged) burn for fuel, mulch or recycle lengths greater than 0.6 metres.
  • Treated timber - reuse, lengths greater than 0.6 metres (or 450mm where this is the spacing of structural framing).
  • Engineered timber products, trellis and other timber products - reuse or recycle panels of greater than 0.5 square metres.
  • Treated or untreated heavy timbers/posts - reuse.

Vegetation

  • Trees - remove and replant specimen trees.
  • Vegetation - mulch or chip for use a ground cover, mulch, compost.
