Your opportunities

Do you want to limit your consumption of mineral fertilizers and maintain a carbon supply in your soil?
The digestate from a methanisation unit can replace your current fertilisation: manure, slurry and replace part of your fertilisers? It is composed of organic matter (carbon), essential fertilizing elements (nitrogen, phosphorus and potassium) and water.

Digestate is produced by the fermentation of crop residue, livestock manure, biowaste, etc. It is made up of organic and mineral substances, key fertilisers (nitrogen, phosphorus and potassium) and water. 

To be recovered, the digestate is generally separated into two phases:

The solid digestate

Considered as a soil amendment, it is highly concentrated in phosphorus (P2O5), potassium (K2O) and organic matter.

Liquid digestate

Considered as a nitrogenous organic fertiliser, it has the advantage of containing nitrogen in the form of mineral nitrogen, which facilitates its rapid uptake by crops as a direct substitute for mineral fertilisers. It can also constitute an additional irrigation system for crops.

Digestate also has the advantage of reducing olfactory nuisances in periods of manure spreading compared to traditional fertilisers: livestock manure and phytosanitary products.

Our proposal

At ENGIE BiOZ, we check the material as it enters the anaerobic digester and the quality of the digestate as it exits to ensure its conditioning and fertilising value and its harmlessness for the soil, crops and ecosystems.
