Case studies

All of the dairy manufacturers participating in the 2010/11 report have been involved in implementing projects to improve their operating efficiency, reduce resource use, improve environmental performance, and/or decrease costs. A number of case studies are included in this report to illustrate the breadth of these activities and related investment, and where detail is available to also illustrate the gains made in environmental performance.
