Project subpage

The main goal of the project was to prepare a product from biogas digestate, a non-hazardous waste for sustaining/increasing the multifunctionality of soils and the nutrient supply of plants. The raw materials used for product preparation was bentonite rock as a mineral and biogas digestate as an organic matter. The bentonite was used as a bearer with its montmorillonite content being suitable to adsorb nutrients from the digestate. Preparation of such material from digestate and bentonite resulted an organo-mineral complex which:

(i) decreases ammonia volatilization from the digestate;

(ii) is produced as solid material of which storage, transportation and application in the land is cheaper and more efficient than those of the liquid residues;

(iii) can be utilized in a more economic way even far from the biogas plant;

(iv) provides the long-term release of nutrients from the product;

(v) contributes to the improvement of soil structure by its clay content;

(vi ) improves soil fertility by enhancing soil microbiological properties.

During the project a prototype equipment was developed for the production of organo-mineral complex fertilizer.
