Report on Scenarios for the Optimisation of Nutrient Input and Reduction of Pollutant Loads by Fertiliser Managements with Processed and Untreated Manure
Manure can be polluted with heavy metals and other contaminants such as organic substances or pathogens. It is a threat for food safety, because these pollutants can be incorporated by the crops. Also, energy production from manure and manure-based products, tradable products of its processing and possibility to recover nutrients has also to be considered with respect to the contaminant content.
This report presents number of existing and upcoming manure processing technologies for different types of manure with respect to nutrient recovery (and optimizing their input into the soil) and reduction of pollutant loads. These technologies were also incorporated into possible chains for manure processing to improve agricultural efficiency and to decrease their negative environmental impacts.
Still, there is a need to study and improve manure treatment technologies, design new ones and implement feasibility studies for different combinations of technologies to reduce pollutants input and maintain stable, balanced nutrient input to the soil by applying manure based or processed products, thus saving the Baltic Sea from eutrophication.
This report was prepared as part of Work Package 4 on Standarisation of Manure Types with focus on Phosphorus in the project Baltic Manure.
