Sources and technologies

New Zealand has developed considerable expertise in the production and use of biogas, particularly from our experience with landfill and sewage gas.

Biogas technologies have reached a level of maturity and automation that can be customised for New Zealand farmers, communities, cooperatives or industrial plant.

The main current and potential sources of biogas in New Zealand are:

  • Landfills
  • Sewage/wastewater
  • Rural organic residues
  • Food processing organic residues
