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
