Utilisation of Digestate
Direct Use as Biofertilizer
​
Digestate, the nutrient-rich residue from AD, is used directly as biofertiliser for agricultural lands. It is the resource which possesses these major constituents of nitrogen, phosphorus, and potassium that are beneficial for plant development.
Benefits: An organic fertiliser act as an environmentally friendly replacement for chemical fertilisers contributing to natural soil fertility and the formation of soil structure without the consequences connected with the usage of synthetic fertilisers.To learn more about Digestate utilization please select the button below.
Separation and Targeted Use:
The digestate can be separated into solid and liquid fractions using mechanical methods, each with its own specific applications.
Liquid Fraction: The liquid component of digestate contains nitrogen in high concentration for crops during vital growth periods. As soon as crops have used this dose, they can further develop with nitrogen added to soil.
Solid Fraction: Having a high amount of phosphorus and organic matter, the so-called anaerobic fraction is perfect for composting and use as a soil conditioner, bringing in a great benefit because it enhances the quality of the soil over time.
Benefits: It permits more pinpointed and effective use of the digestate components, thus, the maximum agricultural benefits and the minimum waste.To learn more about digestation application please select the button below.
