 As a result of the failure of the Wesley Vale project, a major series of scientific studies termed the National Pulp Mills Research Program was commissioned by the Commonwealth Government to support an update and strengthening of the Australian guidelines for this industry sector.At about the same time, significant changes in bleaching technology and waste water treatment in relation to kraft pulp mills were also being made throughout the world.On completion of the scientific studies, the Tasmanian guidelines for any new Tasmanian mill were then developed and published in 2004, which included provisions that meant that any future project must implement either Elemental Chlorine Free or Totally Chlorine Free bleaching technology.
