There are a number of waste streams that due to their inherent nature or characteristics can adversely affect the operation of a landfill site and therefore should be prohibited from landfill disposal.
The following are recommended as not being suitable for disposal to any type of landfill (Class A, Class B or cleanfill):
- bulk liquids (see previous section for definition of liquid waste)
- radioactive wastes1
- lead acid batteries2
- used oil
- explosive, flammable, oxidising or corrosive substances - as defined under the HSNO Act
- refrigerators or freezers, unless they have been degassed3
- PCB wastes.
1 Unless meeting the disposal requirements specified by Section 14 of the Radiation Protection Regulations 1982.
2 Lead acid batteries can be recycled in New Zealand.
3 Phone 0800 NOLOSS for details of a local contractor who can undertake refrigerant recovery.
