+ | ===== Short description ===== | ||
+ | |||
+ | Within NFR category **5.B.2**, __ammonia (NH3) emissions from the anaerobic digestion at biogas facilities__ are reported. | ||
+ | |||
+ | ^ NFR-Code | ||
+ | | 5.B.2 | Anaerobic Digestion at Biogas Facilities | ||
+ | |||
+ | Separately collected organic waste (biowaste) from e.g. households, public garden and park service, food industry, restaurants, | ||
+ | aerobically (composting) and anaerobically (biogas production). | ||
+ | |||
+ | The aim of the treatment is the production of digestate, leading to the recycling of nutrients and organic matter. | ||
+ | |||
+ | The produced digestate is used as fertilizer or soil improver in agriculture or horticulture and also in private gardening. | ||
+ | In Germany, about one third of the organic waste is treated in anaerobic digestion plants and ammonia (NH3) is an important emission to air. | ||
+ | |||
+ | ===== Method ===== | ||
+ | Emissions from anaerobic digestion at biogas facilities are not a key source and of minor priority. | ||
+ | |||
+ | ==== Activity data ==== | ||
+ | Official statistical data (Statistisches Bundesamt, Fachserie 19, Reihe 1: Abfallentsorgung (Waste management), | ||
+ | |||
+ | ==== Emission factors ==== | ||
+ | The emission factors used for calculating NH3 emissions are based on emission data from a research project ((Carsten Cuhls, Birte Mähl, Joachim Clemens; gewitra Ingenieurgesellschaft für Wissenstransfer mbH: Ermittlung der Emissionssituation bei der Verwertung von Bioabfällen; | ||
+ | |||
+ | ===== Uncertainties ===== | ||
+ | The AD from Statistisches Bundesamt have an uncertainty of ±2% whereas the uncertainty for the EF is -18/+920% (ibid.). | ||
+ | |||
+ | ===== Recalculations ===== | ||
+ | When preparing the current inventory data, statistical data are only available for the previous reporting year, as the Federal Statistical Office' | ||
+ | |||
+ | However, for the year 2010, an error has been noticed in the reported waste volume. This error is corrected in the current reporting. Instead of 3.416,300 t of biowaste as reported in 2020, 3.416,944 t were used in the anaerobic digestion plants. NH< | ||
