    • 3. Digestate Waste Nutrient-rich liquid fertiliser Spread onto fields Run-off damage to environment Water-logged fields
    • 4. Digestate: an increasing problem Low-value WASTE Spreading laws tightening – EPA/EU Complex storage & transport No low-cost, simple solution Costly wastewater disposal Costs AD plants millions of £££ a year to treat Simple disposal techniques are unsustainable and limiting AD growth
    • 5. ADFerTech: fertiliser & clean water
    • 6. Benefits Award-winning patent-pending bolt-on for AD plants Turning AD plants into fertiliser factories Remaining water easily disposed Organic fertiliser – less CO2 Storage and competes with synthetic fertilisers Saves money and provides revenue Very significant agricultural & environmental benefits – muck into money
    • 7. Competition At present there are no commercial treatment processes specific to AD liquor. The most common procedure to deal with waste is just spreading/applying it on land A number of dewatering technologies exist for solid- liquid separation of digestate Limited methods to extract and recover the nutrients within the digestate liquid – e.g. Colsen Group (www.colsen.nl) sell the AMFER system
    • 8. Nutrient removal over time ADFerTech system removes up to 90% of COD and majority of N, P and K (food waste feedstock) 0 10 20 30 40 50 60 70 80 90 0 20 40 60 80 100 120 140 160 180 200 %Removal Time, min COD Total N K P
