Geothermal steam
Making steam is the most energy intensive part of paper production. With its unique location within a geothermal field, our tissue mill in Kawerau, New Zealand is the only mill in the world using geothermal steam, instead of making steam with gas-fired boilers. We have been on a programme of continuous improvement to reduce the mills emissions for more than a decade. With this transition to geothermal steam, the total carbon footprint for the Kawerau site is estimated to be 66% lower in 2025 than it was in 2009.1 Further to this, we purchase this steam from the local Māori Iwi.
