The Nutrient Management Centre at the Agri-Food and Biosciences Institute (AFBI), Hillsborough, is currently being commissioned with a key goal to explore technologies which offer opportunities for better nutrient management of slurry and digestate.

Screw Press Separation and Centrifugation are the two established technologies currently being investigated for their impact and effectiveness in removing, off farm, large quantities of solids from farm slurries and digestates i.e. feedstock.

Separation of feedstock produces a solids fraction containing a high proportion of phosphorus (P) which is more economical to transport off farm for both agricultural and non-agricultural purposes.

This is especially important for Northern Ireland, since oversupply of P to grassland has increased soil P levels beyond crop requirement optimum, leading to increased risk of P runoff to water courses and a negative impact on water quality. | For the full story, CLICK HERE
