Sammanfattning

Biofuels manufactured by transesterification from organic fats and oils, usually known as first generation biodiesel, have often been rejected in recent energy policy discussions. Major reasons for this have been the low energy return on investment ratio and greenhouse gas emissions emerging from the production of biodiesel raw material. Studies have indicated that total greenhouse gas emissions from the production chain of first generation biofuels can be equal to fossil fuels or even somewhat bigger.
However, considering the constantly rising energy prices and decreasing fossil energy resources, and the fact that a true substituent for fossils does not exist at the moment, first generation biodiesel could still offer some new possibilities as an energy source at farm level. Because of the limited production capacity and competition with food production, it would be rational to focus the use of this kind of fuel inside the agriculture system.
The object of this review was to examine the use and production of first generation biodiesel at farm level in the present situation. This includes production of biodiesel, suitability for different applications, and economical and environmental evaluation. It was concluded that even though the first generation biodiesel would not reduce emissions, it can assist to save nonrenewable energy. Farm scale biodiesel production is not economically viable at the moment, but the viability is strongly influenced by feedstock price and several other factors.
