We will evaluate the adaption of a concept for nitrogen extraction from waste streams, developed by EasyMining, applied to biogas digestate to produce an ammonium sulfate fertilizer and dilution water. The concept can contribute to increased production of biogas via extended digestion of nitrogen-rich agricultural biomasses. There are good conditions for achieving profitability because only parts of the digestate is processed and the water produced is used to dilute the digester instead of costly municipal water. This reduces the amount of digestate to handle, which leads to lower costs. The evaluation consists of:
• characterize digestate and investigate the need for adjusting the digestate for nitrogen extraction
• further processing of the fertilizer
• study how the concept can be integrated into the biogas plant More Biogas which will expand the digestion of nitrogen-rich solid manure
• study how the fertilizer is best used by farmers
• carry out an economic evaluation
Vi kommer utvärdera hur ett koncept som EasyMining utvecklar för kväveutvinning från restströmmar kan anpassas till biogödsel för framställning av ett attraktivt ammoniumsulfatgödselmedel samt ett vatten. Konceptet kan bidra till både ökad produktion av biogas och biogödsel via utökad rötning av kväverika agrara biomassor. Det finns goda förutsättningar att uppnå lönsamhet eftersom bara delar av biogödseln processas och genom att det producerade vattnet används för spädning i rötkammaren vilket minskar behovet av inköpt kommunalt vatten. Därmed reduceras mängden biogödsel att hantera vilket leder till lägre kostnader. Utvärderingen består i att:
• karakterisera biogödsel och undersöka behov av anpassning av biogödseln för kväveutvinning
• vidareförädling av gödselmedlet
• studera hur konceptet kan integreras i biogasanläggningen More Biogas som kommer utöka rötningen av kväverik fastgödsel
• studera hur gödselmedlet bäst används av jordbrukarna
• genomföra en ekonomisk utvärdering

The project aims to study the long-term effect of structure liming, and to test if minimum tillage can prolong the duration of this effect. The hypothesis is that structure liming effects diminish over time, but by minimizing soil tillage we can prolong this effect. Studies will be performed in six …
