5% or 11,579 tonnes of waste that went to Kate Valley landfill the year to June 2009 was a metal. Types of metals that end up in landfill are broken up into two types 1) Ferrous (steel based metal products) and 2) Non-Ferrous (Aluminium, Copper and Lead based products). For the Christchurch figures we work from the amount of metal that was sent to Kate Valley landfill in the year to June 2009 increased 52% and nationwide metal represents 4.5% (4% Ferrous and 0.5% non Ferrous).
Interestingly, the Scrap Metal Association stated that for 2006 between 495,000 and 550,000 tonnes of scrap metal was diverted from landfill in New Zealand.
