Note: Contaminated wastewater should not be discharged into stormwater drains. This is because of their potential to damage ecosystems in the water bodies such as streams or harbours. Run-off should be discharged into a sewer if allowed under a trade waste consent, or a resource consent should be applied for to discharge into the environment.

A4.7 Cleaner production case studies
By looking at the ‘big picture’, businesses can assess areas in their operation where they can minimise or manage waste. This is called Cleaner Production and means:
- “avoiding or reducing the amount of waste produced;
- using energy and resources efficiently;
- producing environmentally sound products and services;
- achieving less waste, lower costs and higher profits.” (Source: www.arc.govt.nz)
The aim of Cleaner Production is to reduce the adverse impacts of production and service activities on the environment. Implementing Cleaner Production practices has many benefits. These include consistent and significant reductions in energy and water consumption, waste disposal, emissions and associated costs including trade waste discharge costs and landfill charges. Many of these improvements result from simple "good housekeeping" changes or implementing ideas from workers themselves. Often, once Cleaner Production has been achieved in one area of the business, it becomes easier to see other areas in which it can be achieved.
A number of New Zealand companies have been involved in a series of projects that demonstrate the benefits of Cleaner Production. These businesses have received considerable support and assistance from BusinessCare and Christchurch City Council’s Target Zero team. Some of the examples of Cleaner Production initiatives are included in this section. As the New Zealand case studies do not cover the entire range of businesses researched for this report, some of the included examples are from Australia. Where this is the case, it is important to remember that the costs and savings identified are in $AUS.
This section is intended to show what can be done by businesses and does not in any way suggest in any way that this is what the Ministry for the Environment thinks should be done. The businesses shown in the case studies may not carry out the exact processes outlined in the tables above, however they are in the same type of industry. A list of websites containing further information on Cleaner Production case studies is shown in the Bibliography.
