Agricultural biogas digestate is considered as a valuable nutrient source in agriculture of which bioconversion generates certificated organic fertilisers in crumbly, granulated, pelleted forms.

- basal fertilization of arable land or horticulture field,

- starter organic fertilizer at the same time of sowing,

- thanks to the controlled composting the output material with a high quality humus-like material content promotes peat free plant growing media development and production.

Pellets and granules preparing from mature compost with a high durability index and humus stability, potential utilisation in precision agriculture: for horticultural crops, in arable land management.

Controlled composting: compost end-product for basal fertilisation, added-value component to develop plant growing media, plant growth promoting microbial consortium carrier

Applicable for the following

- solid phase animal manures,

- wine industry: grape pomace

- slaughterhouse animal waste,

- municipal sewage sludge,

- agricultural biogas digestate.

The patented procedure is flexibly adaptable to small-, medium-, large sized facilities using exhaust gas as indirect energy source originating from gas engine in the biogas system: 

1.     Nitrogen loss and odor emission reduction applying the bio-based compost pile cover and processed wood waste-FGD gypsum based additive.

2.     Free living nitrogen fixing and aerobic cellulose degrader bacteria number is at least 10⁷/ in 1 gram of the composted material.

3.     The nutrient composition follows currently used starter fertilizers well.

4.     Odorless and pathogen free end-product without a scorching effect on the most delicate plant cultures as white mustard, head lettuce etc.
