The EU-funded LIFE+ 5-year MANEV project, bringing together 8 knowledgeinstitutes in Denmark, Spain, Italy and Poland, has published its finalreport assessing the sustainability of manure management systems inEurope. Livestock in Europe generates 1 400 million tonnes of manure peryear, containing 7 million tonnes of nitrogen (N) ? compared to some 11million tonnes N applied in mineral fertilisers. The environmentalimpact cost of ammonia emissions, greenhouse gases and nitrogen lossesto rivers alone is estimated at 12 300 million ?/year.

Treatment systemsassessed are: acidification, solid-liquid separation, anaerobicdigestion, aerobic biological treatment, composting, evaporation,thermal drying, ammonia stripping and recovery, filtration / osmosis,phytoepuration and land spreading. The report concludes that theappropriate treatment depends on the local situation. Land spreading isthe first option where possible (not local manure surplus), thatnutrient removal should not be implemented without recovery andrecycling, and that aerobic digestion can support nutrient recovery.Also, it is noted that manure acidification will develop if legislationrequires limiting of ammonia emissions, solid-liquid separation isimportant to facilitate nutrient recovery, further work is needed on thequality of recovered products from ammonia stripping, quality standardsare needed to develop a market for composted manure, filtration andosmosis are likely to remain limited because of high cost.

SHORT ABOUT THE PROJECT

Project Industrial animal farms in the Baltic Sea Region - sustainable practices to reduce nutrient loads is a part of a long-term campaign of the Coalition Clean Baltic and Green Federation "GAJA", aiming to reduce the negative impact of large-scale animal production on the environment and local communities in the Baltic Sea Region, particularly by reducing nutrient run-off into the sea. The project is part-financed by the European Union. This website reflects only the view of the Coalition Clean Baltic.
