Agricultural soil pollution is not limited to agrochemistry.

Livestock production systems also contribute.

It is believed that manure is the best fertilizer since it is completely natural and environmentally friendly. However, excessively large volumes of manure and liquid runoff introduce a significant imbalance in the local ecological system. Particularly dangerous is the entrance of liquid manure into water bodies and groundwater as in this case an epidemiological risk arises for the population of nearby settlements.

The risk of contamination of the area with runoff from livestock farms increases manifold especially when animals are fed with synthetic additives and antibiotics whose degradation products are contained in animal waste. 

Heaps of decaying manure carry diseases such as coccidiosis, colibacillosis, salmonellosis and others. Manure from different animal species carries the same risk of pollution.

Also, manure contains ammonia, which enters the atmosphere and poisons living organisms. In a summer, a pig farm for 108 thousand heads per year emits into the atmosphere 159 kg of ammonia, 14.5 kg of hydrogen sulfide, 25.9 kg of dust and 1.5 billion microorganisms per hour. According to estimates, the presence of ammonia in the atmospheric air is up to 0.5 mg/m3 at a distance of 100 to 700 m from a feeding farm of 10 thousand calves and up to 0.044 mg/m3 at a distance of 1.8 - 2 km. An organoleptically specific smell is perceived as strong constant at a distance of 0.7 - 1.2 km from a farm, as weak constant at a distance of 1.8 km and as weak inconstant at a distance of 2.3 - 3 km.

From one poultry farm of 10 million broiler chickens, more than 80 thousand tons of droppings and over 500 thousand cubic meters of waste water are released annually. According to the World Health Organization (WHO), manure and sewage from poultry farms can be a factor in the transmission of more than 100 pathogens of infectious and invasive diseases.

The inner beach area of Cabrillo Beach in the San Pedro port town of Los Angeles tops the list of California's dirtiest beaches. It is unsuitable for bathing for several tens of days a year due to the large number of bacteria that are considered potentially dangerous. A report by Environment America Research and Policy Center says that such a concentration of bacteria could infect an estimated 75,000 bathers a year, USA Today writes. The main culprit for such a disaster is the feces of humans or animals.

Flesh-eating bacteria are a serious threat, which is rapidly spreading along the coastal areas of North America, due to the latter being contaminated with faeces. Such bacteria spread under the skin of a person at a rate of 2.5 centimeters per hour, causing the death of living tissue. In the United States, there are about 20,000 new infections per year.

Solution

The proposed complex is capable of processing any types of manure into high-calorie synthesis gas with high efficiency. So from one ton of unprepared pig manure, one may get up to 386 cubic meters of gas, which is equivalent to 0.81 megawatts of electricity.

The mobility inherent only in our complex will allow you to place it in any convenient place and then easily move it if necessary, which will reduce the cost of transporting manure.

The resulting syngas can be used for power supply and heating in the cold season, which can reduce the costs for livestock farming.
