About BNNZ

Welcome to Biochar Network New Zealand (BNNZ). We are a membership organisation dedicated to promoting and supporting activities leading to widespread awareness, understanding, and acceptance of biochar in New Zealand.

What is Biochar?

Biochar is activated charcoal which can be used to lift the productivity of agriculture and as long-lived carbon stores in soils. It can be used to enhance water quality and as a bioremediation tool for contaminated soils. The production of biochar can also deliver bioenergy and deal with many types of ‘liability’ biomass that offset carbon emissions.
