Biochar has the potential to play an important role in our response to climate change - the process adds carbon back into our environment, healing our atmosphere, waterways and soils.

Join Te Au: Liquid Constituencies exhibiting artist collective Te Waituhi ā Nuku: Drawing Ecologies, Phil Stevens from Slow Farm, Urs Signer and Tuhi-Ao Bailey of Parihaka Garden and the Gallery team to observe a biochar process and discover how it is made and learn about its benefits.

The biochar process uses a specially designed kiln to burn dry twigs and branches in a low-oxygen, smoke-free environment, before rapid cooling with water from below. Through this process, the volatile gasses in the timber are burned off, creating a highly porous, fine-grained charcoal.

This biochar can then be reintegrated into the local environment, becoming part of a climate change solution - it has the potential to heal our atmosphere through long-term carbon sequestration, to heal our water through nutrient filtration, and to heal our soil by enhancing the habit of soil life.

To get an introduction to the potential and importance of biochar, visit the Te Au: Liquid Constituencies exhibition and the art works by Te Waituhi ā Nuku: Drawing Ecologies, a collective of artists and researchers from around Aotearoa and overseas who are actively exploring the potential of biochar for wetland and stream restoration, as a soil amendment, as a tool for carbon sequestration, and as an artistic medium.
