waste stabilisation or hazardous waste disposal practices• materials that may present a risk to human or animal health such as

Christchurch Cleanfill Bylaw

Commitment in Christchurch’s Waste Management Plan to work

towards zero waste, and a realisation that large quantities of

materials that could be recycled or reused were being disposed of

in cleanfills.

9

A whole system approach. Cleanfills are not treated in isolation

but seen as part of the waste management system that involved

control over landfill disposal and awareness of impacts on

recycling infrastructure. Controls imposed on one part of the

system will impact on other parts of the system and it is critical to

recognise this from the outset and design the systems in an

integrated fashion.
