Field biomasses are energy plants grown on mineral and peat soils. For example reed canary grass, hemp, turnip rape; fast growing woody plants like energy willow; and parts of grain crops like straw.
Field biomasses should be grown on fields that have become free from food production, fallows, or former peat production lands so that food production does not have to compete with biomass production.
Field biomasses can be burned as such, or they can be processed into solid or liquid biofuels. An example of liquid biofuels is bio diesel.
Field biomass can be prepared of the following raw materials:
- reed canary grass
- turnip rape
- fast growing wooden plants, such as energy willow
- parts of grain crops, such as straw
