Spreading digestate (liquid effluent) from biogas plants generates high costs. Changing legal regulations may even aggravate the situation. This is even more the case for facilities operating in an area with high nutrient load. What could be more reasonable than reducing the digestate volume? The concept becomes even more attractive if excess heat from a CHP is available which is not being used yet or just partially.
