Industrial Processing

Processing industries located close to geothermal resources can use eco-friendly and renewable geothermal energy for heating, which provides economic and productivity benefits.

Timber Drying, Tenon (Taupo)

The Tenon operation in Taupo harnesses two-phase geothermal fluid from the Tauhara geothermal field, using some 600 TJ/ year of heat energy, for kiln drying sawn timber.

The Kawerau timber facilities have used geothermal energy for timber drying since the late 1950's. This is the world's largest single user of geothermal steam for process heat using some 5000 TJ/year of geothermal heat energy. Three large direct geothermal heat utilisation activities are associated with the timber industry at the Tasman Mill at Kawerau.

One of these, SCA Hygiene Australasia’s tissue production plant in Kawerau, produces paper produces for household brand names. In 2010, they converted the steam system of three paper machines to geothermal energy to minimise their carbon footprint and reduce costs.
