Reuse of minerals and organic matter
Reuse of minerals and organic matter
Organic fertilisation instead of slurry and artificial fertilisation.
Fertiliser contains artificially manufactured minerals, mainly Nitrogen (N) and the fossil raw materials like phosphate (P) and potassium (K). This ensures accurate fertilisation of the plant.
In contrast, artificial fertiliser does not contain any organic matter that improves biodiversity and soil life. The extraction, the production and transport of artificial fertiliser makes a significant contribution to the CO2 footprint worldwide. Due to the costly production process and the scarcity of raw materials, artificial fertiliser is an expensive fertiliser, which means that not everyone has access to it.
The storage of slurry generally takes place under oxygen-free conditions (anaerobic) which results in a decaying process which is harmful to the soil or even dangerous .This causes the formation of decaying gases or so-called slurry gases, containing (life-threatening) dangerous gases such as methane (CH4), Ammonia (NH3) Hydrogen sulphide (H2S), Blue-acid gas (HCN), N2O (nitrous oxide) and Carbon dioxide (CO2).
As a result this degradation reduces the availability of minerals and organic matter, causes flies to be attracted by these gases and can even transmit diseases to livestock, and last but not least, most of these gases are greenhouse gases and are harmful to the atmosphere.
Slurry has harmful effects on biodiversity in soil life, while good and mature manure rich in structure stimulates biodiversity such as bacteria, fungi and worms in the soil and thus makes a greater contribution to soil biodiversity and fertility.
Because the manure storage is connected to the barn by the concrete slatted floor, especially in closed barn systems, the animals are also more or less exposed to manure gases from slurry such as ammonia (NH3). The current low-emission concrete floors prevent this to some extent, but the emission gases now accumulate under these closed low-emission concrete floors, which can lead to dangerous situations.
The Filterfloor separates the urine and faeces from each other and thus prevents slurry. The two manure streams that are created now, thick and thin fraction, offer possibilities for other manure storage systems.
Within the mineral cycle, we reuse the minerals from the residual flows efficiently by using recyclable raw organic materials such as manure as much as possible.
Phosphate is one of the most important elements for life on earth. i.e. without phosphate there is no life possible. Because the phosphate reserves are finite and are running out, it is important to deal with this efficiently and to reuse the unused minerals from residual flows such as manure.
Potassium is also a raw material that is extracted by mining and this is a costly process that causes greenhouse gas emissions. Sustainable reuse of minerals makes an important contribution to the transition to the regenerative agriculture. In addition, we are less dependent on the economies supplying phosphate. (from mines that are mostly owned and by China or African countries).
Preventing slurry by separating into two streams a thick and a thin fraction with the Filterfloor panel, organic matter and nutrients remain better available. This results in customised fertilisation so that fewer losses occur and savings can be made on the use of artificial fertilisers. Organic fertilisers improve soil biodiversity by adding organic matter which improves soil structure and humus formation.
Filterfloor is a start-up that develops and markets a unique, patented Filterfloor system for manure separation at the source. As a start-up, we have gained several years of experience. The development has reached the final phase, which is why we are looking for early adopters who are prepared to give access to their barns for testing the patented Filterfloor system. These pilot projects are intended for research into final emission measurements.
