The NUTRICAS tool can be accessed here, and further details on the tool can be read here, and here.

NUTRICAS is a tool aimed at helping support decision making processes by forecasting costs, performance, and end products for specified nutrient recover and re-use technology combinations on digestate. Based on data from the SYSTEMIC European demonstration project, focused on five large-scale biogas plants which use innovative nutrient recovery processing techniques, and specifically the technologies occurring most frequently at these plants, including:

• Liquid-solid separation techniques
  • Centrifuge (with and without polymer addition)
  • Screw press (with and without polymer addition)
  • Belt press (with polymer addition)
  • Dissolved Air flotation (with polymer addition)
• Nitrogen (ammonia) stripping-scrubbing
  • With H2SO4
  • With gypsum
• Evaporation and condensation
  • With prior acidification
  • Without prior acidification
• Membrane filtration technologies
  • Microfiltration + reverse osmosis
  • Reverse osmosis
• Phosphorus stripping and precipitation: RePeat
• Thermal drying
  • fluidized bed dryer.

By specifying different combinations of technologies, users can compare the cost and outputs of different biorefinery systems.
