Abstract:
The production of mineral nitrogen fertilisers is based on fossil resources and represents one of the largest greenhouse gas emission posts in crop cultivation. In this study, the possibility to produce nitrogen fertilisers based on renewable energy, so called green nitrogen fertilisers, is investigated. By using life cycle assessment methodology the greenhouse gas emissions for producing and using green nitrogen was calculated. It was found that by using biomass as raw material for nitrogen fertiliser production, the emissions can be largely reduced compared to using fossil fuels. Also, by using green fertilisers in crop production, the carbon footprint per kg produced crop can be significantly lowered, in the studied scenarios a reduction of 86% and 36% in green house gas emissions from cultivation of winter wheat was found.
