Within the framework of the Dutch pilot Mineral concentrate a monitoring program was conducted, subsidised by the Ministry of Agriculture, Nature and Food Quality, to generate data on the current quality of mineral concentrates, in relation to the criteria of the pilot Mineral concentrate (MC) of the Netherlands, and the performance of their production processes. These criterions are established to ensure high nitrogen use efficiency without an environmental impact of the concentrate. The monitoring was linked to information requested by the EU Joint Research Centre (JRC) to support the development of quality criterions for N fertilisers recovered from animal manure, revered to as RENURE, within the context of the Nitrates Directive. It was also linked to relevant data on the quality of the permeate from reverse osmosis to substantiate quality requirements for discharge on surface water of effluents from manure processing plants. The parameters of the monitoring included primary and secondary nutrients, heavy metals, antibiotics, pathogenic bacteria and viruses. This report presents the results of the monitoring.
