Biomass and Bioenergy
Bioenergy provides a real alternative to fossil fuels for many applications. New Zealand's geography and climate have placed it at the forefront of countries internationally for the production of food and fibre. This same natural advantage has a prime role in making New Zealand internationally competitive in bioenergy production of many forms.

Biogas and Landfill Gas
Biogas is a gas produced during the biological breakdown of organic
matter which can be used to provide energy. The gas is produced
from the decay of vegetation and other organic materials such as
animal manures, sewage treatment sludge or food processing
waste. This can occur in places where there is little or no oxygen
such as in a landfill (where it is known as landfill gas) or under
controlled conditions such as an engineered waste digester.
Biogas emitted from landfill sites or engineered waste digesters can be used to provide heat or to generate electricity.

Biogas Systems – New Zealand
Vast quantities of methane (sometimes called bio-gas or "swamp gas") are generated every year by the decomposition of organic material. Methane gas is a near twin of the natural gas that the gas companies and power utilities supply for heating the home, cooking and for commercial/industrial use.
Instead of being harnessed like natural gas, however, methane has traditionally been considered as merely a dangerous nuisance that should be disposed of as fast as possible. Only recently a few organisations have begun to regard methane as a potentially revolutionary source of controllable and renewable energy.
