This guide provides good practice advice to improve recovery rates for all types of metal from construction and demolition (C&D) sites.

The aim is to assist the resource recovery industry to provide collection and transportation services that:

• maximise the amount of metal diverted from landfill and cleanfill
• minimise contamination
• meet the requirements of the construction or demolition client and the recycling operator

The metal recycling industry in New Zealand is well established. This guide is not about how to process or recycle metal, but gives tips on providing a collection and transportation service that suits the demands of the building industry. This is relevant to both the recycling operators who provide a collection service and the transport operators who serve the recycling industry.

This guideline covers:

• what metal can be recycled from a C&D site
• collection and transportation services
• resources and contacts
• other guidelines in this series.
