6. Prohibited Wastes

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 wastes [Unless meeting the disposal requirements specified by Section 14 of the Radiation Protection Regulations 1982.]
• lead acid batteries [Lead acid batteries can be recycled in New Zealand.]
• used oil
• explosive, flammable, oxidising or corrosive substances - as defined under the HSNO Act
• refrigerators or freezers, unless they have been degassed [Phone 0800 NOLOSS for details of a local contractor who can undertake refrigerant recovery.]
• PCB wastes.
