Wildlife Management International (WMI) Pty Limited, which owns and operates Crocodylus Park has implemented a comprehensive waste minimisation programme which has proven to be a successful cleaner production initiative. WMI has ensured the success of its initiative by fully integrating the waste minimisation program into its management planning processes. As a consequence, the waste minimisation programme is given full consideration during budget reviews, marketing forecasts and work schedules.
The cleaner production initiative adopted by WMI for Crocodylus Park has involved simple modifications to their housekeeping and work practices. These changes have resulted in a significant reduction in the volume of generated waste for final disposal. Waste reduction has occurred in the areas of solid waste, liquid waste, water management and energy management. As a consequence of applying waste minimisation strategies to its work practices, WMI has achieved significant benefits in the form of a 'cleaner environment', reduced operating costs and social benefits for the community.
Wildlife Management International (WMI) Pty Limited is a private organisation, which provides research management and educational services, and manages Crocodylus Park in Darwin. Based in Darwin, WMI is on the gateway to Asia and has close links within the region. Their mission statement is:
"The mission of WMI is to provide high quality research, management and educational services that promote and integrate wildlife conservation with the diverse needs and values of people."
Besides interests in specific taxa of fauna and flora, WMI has particular interests in endangered ecological communities and key threatening processes. In addition, the following issues are of interest to WMI:
WMI has identified the need to operate and manage Crocodylus Park by utilising the most efficient and effective work practices and procedures so as to ensure its viability. The traditional activities of Crocodylus Park, tourism, wildlife management and research generate a sizeable volume of waste. This waste consists pre-dominantly of solid waste, liquid waste and organic agricultural waste. Both the composition and generation rate of the total waste stream varies significantly from day to day and from the dry season to the wet season.
Prior to the adoption of the cleaner production initiative, WMI did not practice any form waste management such as recycling or waste minimisation. The generated co-mingled waste was collected and disposed of off site, thus producing a problem in another environment. As a direct consequence of this waste management problem, the facility's operating costs were high. These costs were due to an expensive collection and disposal service that in turn significantly impacted upon the overall profitability of Crocodylus Park.
Given the competitive nature of wildlife conservation parks within the Northern Territory, it was essential for WMI to reduce the operating costs of Crocodylus Park so as to ensure its viability. As a consequence, WMI recognised that the management of Crocodylus Park could be greatly improved both environmentally and economically through the prevention, reduction and minimisation of waste. This wastage included not only solid and liquid waste but also unnecessary energy and water consumption.
The waste minimisation process that WMI incorporated into the operation of Crocodylus Park as their cleaner production initiative is an extensive and long-term waste minimisation strategy. The strategy was formulated during 1997/1998, after a comprehensive audit of the premises and procedures undertaken at Crocodylus Park. As a consequence of the audit, WMI have achieved a significant reduction in waste volumes by implementing simple changes to their work practices and procedures. They have achieved this primarily by separating the waste materials at the source of generation thereby allowing for reuse and/or individual treatment of the unmixed fractions. Table 1 summarizes the cleaner production practices that have been adopted. These practices are subject to a continual review process so as to ensure the implementation of the most effective strategy for WMI's operations within Crocodylus Park.

|Broader Resource Strategies||
The simple modifications to work practices and procedures implemented by WMI has resulted in many significant economic and environmental benefits. The direct benefits of adopting the cleaner production practices within Crocodylus Park include:
Operation reduction in Annual Expenditure
Economic Advantages (%)
|SAVINGS||PRACTICES||% p.a. (within this category of operation)|
|Waste Disposal||Free removal of recyclables, and reduction in solid wastes through purchasing policy, recycling policy and on-site disposal||15%|
|Water Management||Installation of a dam, seasonal restrictions on water use, and use of mulch to enhance water retention.||85%|
|Purchasing Policy||Implementation of more effective purchasing policy||10%|
|Power Management||Implementing power usage minimisation strategies||25%|
|Broader Management Strategies||Use of recycled materials and facilitating volunteer placement programmes||5%|
|NET BENEFIT (within the above categories||40%|
The main incentive for WMI to adopt cleaner production practices was their ongoing corporate commitment to environmental management. They saw cleaner production as a method to improve resource management, minimise environmental impact and decrease waste generation within their education and research facility.
No barriers were encountered in implementing this cleaner production initiative. In the management of Crocodylus Park, WMI is committed to a program of waste minimisation and practical environmental management.
The initiatives documented in Table 1 above were implemented during 1997 and 1998 and as at 2001 have been maintained with ongoing benefits to the company, especially in the areas of water and energy conservation/savings. New initiatives are introduced as new animal displays and visitor amenities expand. One such example is the addition of native fish to ponds to assist in the control of excess protein and mosquitoes. Notably, the fish were collected from a waterhole that dries out in the dry season killing all the fish within it.
Casestudy implementation: 1998
Further initiatives: 2000
