Benefits of biogas production
A reliable source of energy
Biogas is a reliable source of energy and can be produced both from renewable raw materials (corn silage, cereals, green mass), and from by-products and waste of organic origin. Unlike renewable energy sources – wind and sun, biogas energy is continuous and independent of weather conditions and time of day.
High level of environmental friendliness
The production of energy from biogas does not require the use of fossil sources, but the atmosphere does not get additional volumes of carbon dioxide. Although biogas combustion with the production of thermal and electric energy generates carbon dioxide, however, it is identical to that which is naturally released during the conversion of organic raw materials. Therefore, these emissions of biogas production are classified as harmful to the environment.
Energy is where it is needed
Countryside or industrial area? Biogas can be produced where it is needed. Accordingly, both thermal and electrical energy from biogas can be obtained where it is expedient and necessary. This allows you to maintain the potential of power plants and nuclear power plants.
Benefits of operating biogas complexes are not only industrialized countries. For developing countries, biogas production – the ability to generate an independent source of energy – is an integral part of economic development.
A number of European countries have proved the expediency of building biogas complexes in the availability of several settlements – consumers at the same time, in order to meet the needs of the population in thermal and electric energy, while solving the issue of the recycling of organic waste. This approach contributes to a significant reduction in the use of firewood and prevents the cutting of vegetation and forests.
More than electric and thermal energy
In addition to the production of biogas, thermal and electric energy, biogas production generates a valuable product – high quality fertilizers with virtually unchanged and even more concentrated nitrogen, phosphorus and potassium oxide. Thus, biogas production creates a practically closed waste-free chain, because organic waste is recycled and returned to the soil in a safe and affordable form for plants.
Biofertilizers after biogas production have several advantages: they are better assimilated and more valuable for plants than biogas complexes that are not processed in waste. Nitrogen is attainable by about half as fast-acting ammonia. The second half is still organically linked, and hence biofertilizers are excellent fertilizers for crops.
In addition, bio-fertilization after biogas production has virtually no odor in comparison with, for example, unprocessed manure, which is explained by the chemical and biological transformations of odorous sulfur compounds with methane fermentation.
The introduction of these bio-fertilizers into agricultural crops is much easier compared to the application of traditional organic fertilizers.
