Pacific Class No. 15 2004

This project has been planned for some 25 years since the owner planted his forest on an uneconomic hill country farm. The pines from this forest have already been logged and it is now time for the hardwoods ie Eucalyptus, to be harvested and processed on site. In setting up this sawmill and drying facility, all powered on wastes from the forest, it is hoped to provide a show case from which to demonstrate technologies that provide visitors with a practical appreciation of sustainable renewable energy at work. Provision is also being made to locate a training facility for forestry engineering students on site.
