Bluetector has developed a purely biological treatment of manure, simply turning it into water. The treated water is ideal for irrigation, addressing the increasing scarcity for agricultural usage while solving the global difficulties managing manure volumes.

The BlueBox Ultra has been developed for the purely biological manure treatment and works the same way as a municipal sewage plant: the liquid nitrogen is converted into elementary, gaseous nitrogen in the bioreactor. The nitrogen in the liquid phase is reduced by an average of 95%.

The BlueBox converts the manure into a water which only contains traces of nitrogen and phosphorus and is therefore ideally suited for the irrigation of plants.

This makes the effluent water applicable for irrigation and other applications without any additional treatment. Only a fraction of the otherwise required area is needed for its spreading.

The treatment with the BlueBox Ultra eliminates the need of expensive and environmentally harmful manure transports, where the manure often has to be transported over hundreds of miles.

Manure is characterized by high concentrations of nitrogen and phosphorus. Therefore the dumping of manure on farmlands becomes more and more difficult, especially more expensive.

Increasing nitrate contamination in groundwater and corresponding new regulations make dumping even more difficult.

The manure treatment in the BlueBox Ultra is based on a highly efficient bioreactor. This results in significantly lower costs compared to conventional manure disposal.

Bluetector's manure treatment systems are designed in such a way that they can be easily integrated into the existing infrastructure on a farm or biogas plant, without necessarily having to build new tanks for the bioreactor. Existing tanks should have a minimum height of 6 metres and a diameter of 15 metres, so that the BlueBox Ultra can be optimally integrated.

Existing screw presses or centrifuges can also be integrated into the treatment process, so that the investment costs for a manure treatment system can be kept as low as possible.

The equipment container for a system for the treatment of 100 tons of manure per day consists of two 40-foot containers, which are installed next to each other. The pumps, the blowers, as well as the entire electronics and control system are located in these containers.

There is too much nitrogen in the soil and groundwater. This comes mainly from manure. But while human faeces have to be cleaned at great expense in wastewater treatment plants, manure is still considered a "valuable fertilizer" - although manure and human faeces are almost identical in their composition.

It is high time to protect what is really valuable: our groundwater! We must protect our groundwater from overfertilisation with manure. Bluetector offers a simple and low-cost solution to treat manure purely biologically while preserving the precious phosphorus.

The denser the black spots, the higher the concentration of manure - and thus the poisoning of soil and groundwater with nitrate. The first farms and biogas plants in black zones have already had to shut down.

Necessity makes for ingenuity: manure transports have meanwhile developed into an important economic industry in Europe. The liquid manure is transported over hundreds of miles and spread directly from the road onto the fields. The current cost is around 5-10 cents per gallon, depending on the region. And the tendency is strongly upwards.

No sensible person today would demand that human excrements should be spread as fertilizer on fields, and that huge storage tanks be used for that. On the contrary: human " manure " is purified in wastewater treatment plants to protect groundwater, rivers and lakes. The same should also apply to manure.

The Bluetector technology for manure treatment has the potential to reduce harmful methane and nitrous oxide emissions from agriculture and can save up to 977 million tons of CO₂ per year - that is over 2% of total global greenhouse gas emissions per year.

Agriculture contributes about 10% to global greenhouse gas emissions. This is mainly due to methane emissions from livestock farming and manure spreading, as well as to nitrous oxide emissions from agricultural soils due to nitrogen fertilization.

In 2015, agriculture accounted for around 58% of total methane emissions (CH₄) and 81% of nitrogen dioxide emissions (N₂O) in Germany. German agriculture was responsible for total emissions of around 67 million tonnes of carbon dioxide (CO₂). This corresponds to 7.4% of Germany's total greenhouse gas emissions this year. This makes agricultural emissions the second largest source of greenhouse gases in Germany after energy-related emissions from stationary and mobile combustion (84.5%) and before process-related emissions from industry (6.8%).

Dinitrogen dioxide, also known as nitrous oxide, is a greenhouse gas that is about 300 times more harmful to the climate than carbon dioxide. The main sources of nitrogen dioxide are nitrogenous fertilizers used in agriculture and animal husbandry. Methane is about 25 times more harmful to the climate than CO₂. Around 37% of the methane emitted worldwide comes directly or indirectly from animal husbandry. Among other things, methane is produced during fermentation in the stomach of cows. In addition, 19% of the total methane emissions of German agriculture were accounted for by the storage and application of liquid manure.

The Bluetector solution almost completely reduces methane and nitrous oxide emissions from the storage and application of liquid manure in the fields. The Bluetector solution eliminates the need to transport liquid manure by truck over hundreds of kilometres, saving millions of tonnes of CO₂ emissions every year. In contrast to the microbes typical of biological purification stages, anammox bacteria do not require oxygen and also consume the greenhouse gas nitrous oxide. Scientific studies have shown that treatment plants with a de-ammonisation process in which oxygen is replaced by nitrite produce significantly lower N₂O emissions than conventional treatment plants. The most important factor in reducing N₂O emissions is to ensure homogeneous operating conditions to avoid fluctuations in conditions that would lead to increased nitrous oxide emissions. Since the composition of the slurry properties is stable, the conditions in the BlueBox system are not subject to fluctuations and thus meet the requirement for homogeneous operating conditions. A pure anammox process does not work in the treatment of manure or biogas fermentation residues due to the high contamination with organic pollutants; anammox bacteria react very unfavourably to slight changes in the water properties. The Bluetector system integrates the Anammox process into a conventional system that also eliminates organic pollutants and thus achieves the advantages of using Anammox in the treatment of manure and fermentation residues. As agriculture is an important producer of greenhouse gases, our technology can have a very positive effect.
