Nitrogen fertilising products based on manure and organic residues: supporting literature of the SYSTEMIC factsheets

The EU H2020 project SYSTEMIC has taken up the challenge to recover nutrients from animal manure and biowaste. Biowaste, like animal manure, sewage sludge and food and feed waste, forms the most abundant waste stream in Europe and hence the most prominent potential resource for the production of biogas and the recovery and reuse of mineral nutrients like phosphorus (P), nitrogen (N) and potassium (K). The application of nutrient recovery from waste is hindered by regulatory requirements amongst others the Nitrates Directive 91/676/EEG. This report gives an overview of the agronomic and environmental performance of nitrogen fertilising products made from manure. These products are ammonium sulphate and ammonium nitrate from air scrubbers and ammonia strippers, mineral concentrates produced by reverse osmosis, condensated ammonia water from capturing ammonia and liquid digestate produced by separation of digestate. For each fertilising product the state of the art of information on the technology, characteristics, composition, agronomic effectivity and risk assessment on contaminants, pathogens and other components is given. The information is condensed to a factsheet. These factsheets are also found at the website of the SYSTEMIC product (https://systemicproject.eu/downloads/).
