+ | 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 (NH< | ||

+ | Emissions from anaerobic digestion at biogas facilities are not a key source and of minor priority. | ||
