Glossary

Beneficial re-use
The re-use of a reprocessed material or substance which would otherwise be disposed of to landfill or cleanfill.
 
Biosolids
Biosolids are a by-product of sewage collection and treatment processes. They have been treated and/or stabilised to the extent that it is possible to beneficially re-use them. Also known as sewage sludge.
 
Cleanfills
Cleanfills are waste disposal sites that accept only inert wastes that, when buried, will have no adverse effect on people or the environment. These include materials such as clay, soil, rock, concrete and bricks.
 
Community recycling facilities
Recycling services which are provided to the local community. These include kerbside and drop-off facilities provided by local authorities.
 
Commercial waste
Waste generated from a commercial business or industry.
 
Construction and demolition waste
Waste generated from the construction or demolition of a building including the preparation and/or clearance of the property or site. This excludes materials such as clay, soil and rock when those materials are associated with infrastructure such as road construction and maintenance, but includes building-related infrastructure.
 
Contaminated sites
Contaminated sites or contaminated land is described as land that has hazardous substances in or on it and is more contaminated than an applicable NES, or has, or is reasonably likely to have, significant adverse effects on the environment.
 
Domestic recycling
Materials recycled by the householder via kerbside collection or drop-off facilities.
 
Design for the environment
Design for the Environment refers to products that are designed and managed so that minimum environmental impact is caused by their generation, use, recovery and disposal.
 
Drop-off facilities
Recycling services provided to the local community through a specific site or sites where recycled materials can be dropped off.
 
Farm plastics
Chemical containers and silage wrap used on farms which are dangerous to burn or bury on the farm, and can be hazardous to dispose of to landfill, if not properly managed.
 
Green waste
Also known as garden waste, this includes waste produced through gardening both commercial and domestic.
 
Hazardous substances
Hazardous substances include, but are not limited to, any substance defined in section 2 of the Hazardous Substances and New Organisms Act 1996 as a hazardous substance.
 
Hazardous waste
Hazardous waste refers to materials that are flammable, explosive, oxidising, corrosive, toxic, ecotoxic, radioactive or infectious. Examples include solvents and cleaning fluids, medical waste, unused agricultural chemicals and many industrial wastes.
 
Kerbside facilities
Recycling services provided to the local community through the collection of recycled materials directly from households.
 
Landfill
A landfill is an area used for the controlled disposal of solid waste.
 
Liquid waste
Liquid waste is waste generated in, or converted to, a liquid form for disposal. It includes point and non-point source discharges, stormwater and wastewater.
 
Organic waste
Organic waste includes garden waste (more commonly known as ‘green waste’), food scraps, biosolids and commercial organic wastes such as paunch grass and food-processing waste. It can sometimes include other wastes that may biodegrade in landfill such as paper, cardboard and untreated wood.
 
Organochlorines
Organochlorines are chemicals that contain carbon and chlorine atoms joined together. Some organochlorines are persistent and present a risk to the environment and human health. Examples include dioxin and polychlorinated biphenyls (PCBs).
 
Product stewardship
Product stewardship is a ‘cradle to grave’ tool that helps reduce the environmental impact of manufactured products. Under product stewardship schemes, producers, brand owners, importers, retailers, consumers and other parties accept responsibility for the environmental effects of their products – from the time they are produced until they are finally disposed of.
 
Recovered materials
Materials which have been collected for recycling and reprocessed to create a new material.
 
Recycled
The process of reprocessing a waste material into a new material.
Recycling
Recycling describes the action of the consumer when collecting and depositing materials which can be recycled (eg, glass, plastic containers and bottles, aluminium and steel cans, paper and card) and the action of industry when reprocess recycled materials.
 
Residual waste
Remaining waste material once activities to reduce, re-use, recycle, recover and treat have been undertaken.
 
Resource Management Act
Resource Management Act 1991 is New Zealand’s main piece of environmental legislation and provides a framework for managing the effects of activities on the environment.
 
Sewage sludge
Sewage sludge is a by-product of sewage collection and treatment processes. Also known as biosolids.
 
Solid waste
Solid waste is all waste generated as a solid or converted to a solid for disposal. It includes wastes like paper, plastic, glass, metal, electronic goods, furnishings and organic wastes.
 
Solid Waste Analysis Protocol
Solid Waste Analysis Protocol is a baseline measurement programme to provide generic solid waste composition data for New Zealand.
 
Special waste
Special wastes are wastes that cause particular management and/or disposal problems and need special care. Examples include used oil, tyres, end-of-life vehicles, batteries and electronic goods.
 
Stewardship
Stewardship, or kaitiakitanga, puts a duty of care on everyone – government, business and the community – for waste prevention and resource recovery.
 
Storm water
Storm water results from rainwater runoff that is channelled through drains from roads and urban properties into waterways and the sea.
 
Trade waste
Trade waste refers to liquid wastes generated by business and disposed of through the sewerage system. Trade waste includes a range of hazardous materials resulting from industrial and manufacturing processes.
 
Treated timber
Treated timber is wood which contains chemicals (eg, copper, chrome, arsenic) which require careful disposal as it can be harmful to the environment.
 
Used oil
Oil contaminated through use with substances that can be hazardous to human health and the environment.
 
Waste
The New Zealand Waste Strategy defines waste as any material, solid, liquid or gas that is unwanted and/or unvalued and discarded or discharged.
 
Waste disposal
The final placement of material (solid, liquid or gas) which is unwanted and/or unvalued and discarded or discharged.
 
Waste electronic and electrical equipment
Waste electrical and electronic equipment is electrical and electronic equipment (those products that are dependent on electric currents or electromagnetic fields to work) which are no longer required and are due for waste disposal. Examples include fridges, fluorescent lamps and toasters computers and mobile phones.
 
Waste hierarchy
The waste hierarchy orders preferred waste management options. The most preferred option is reduce, followed by re-use, recycling, recovery, treatment and, lastly, disposal.
 
Waste management plans
Waste management plans which are produced by territorial authorities outlining what their waste management and minimisation activities are in their area.
 
Waste minimisation
Waste minimisation refers inclusively to all activities aimed at preventing, reducing, re-using or recycling waste.
 
Waste prevention
Waste prevention refers to practices that avoid and reduce the generation of waste.
 
Waste sector
The waste sector is the collective term for industries and businesses specifically involved in the collection, disposal and/or reprocessing waste and recycled materials.
 
Wastewater
Wastewater is a by-product of sewage, liquid trade waste collection and treatment processes.
