The technology aims at precipitating of phosphorus, nitrogen and the production of soil improver based on manure and liquid biogas digestates. The treatment of the input takes place in several consecutive steps.
- Dissolving of all nutrients bound in the solid fraction, especially phosphorus
- Solid-liquid separation. The solid output is already nutrient-poor and can be used can be used as a peat substitute product.
- Phosphate precipitation from liquor – recovered as phosphorus salt
- Nitrogen recovery by stripping as ammonium sulphate
At the end of the process a nutrient-poor water remains, which can be discharged or used for raining.
Compared with conventional fertilizer production, the life cycle assessment of the process is at least 60% better in the impact categories acidification potential, eutrophication potential, global warming potential, photochemical ozone creation potential and primary energy from nonrenewable resources.
