“…Of the many problems related to significant livestock concentrations, the most important is the problem of manure management, which extends beyond the scope of the production process itself. A significant quantity of animal fertilizer provides a clear signal to look for solutions, i.e., rational methods of its processing and use, particular for slurry [1][2][3][4].…”

Methane production by fermentation is a complex biochemical process, in which micromolecular organic substances are broken down by anaerobic bacteria into simple stabilized chemicals—mainly methane CH4 and carbon dioxide CO2. The organic matter of the slurry consists mainly of fats, proteins and carbohydrates. As a result of biochemical changes in the process of anaerobic decomposition, some of this matter is mineralized to simple chemical compounds. Cattle and pig husbandry offers enormous potential for useable biogas plant substrates. As a result of the constantly increasing amounts of animal husbandry products, and increasingly stringent environmental protection requirements aimed at reusing natural fertilizers, it is necessary to look for alternative processing methods. The need for efficiency in obtaining biogas from substrates (e.g., manure) was met by the laboratory stand presented in this article, for which the Polish patent No. 232200 was obtained. The new technology also allows leaching of the organic liquid, e.g., from manure, and subjecting it to methane fermentation. The solution allows the individual elements of the technological line that determine the fermentation process to be tested under laboratory conditions. It also allows testing of the substrates in terms of fermentation, to determine their physical and chemical characteristics, and then to characterize the fermentation process in terms of the quality and quantity of the resulting biogas and the quality of post-fermentation residues. Compressing biogas for local distribution was also proposed. As part of the research, using a laboratory stand, the organic matter was leached from manure, for the purpose of biogas production. In addition, the biogas yield from manure at varying degrees of maturity was assessed. The best properties in terms of biogas yield forecasting were demonstrated by manure composted for 4–8 weeks.

“…Therefore, this article did not consider treating them as organic fertilizers. During fermentation process, various components in food waste are converted into stable humus-like substances and rapidly available nutrients, which can be quickly hydrolyzed (Bi et al 2019), or directly absorbed by plants (Hou et al 2017). Those materials could also improve nutrition levels of the soils (Du et al 2018).…”

Biodegradable household garbage contains a large amount of nitrogen which could be used as organic fertilizers to produce organic foods, thus mitigating environmental pollution at the root. However, due to the complex composition of household garbage and its uneven distributions from urban to rural areas, it is not clear how large the biomass nitrogen reservoir is in a certain country or region. Here we took China as a case, systematically analyzed the amount of biodegradable household garbage resources and their nitrogen reservoirs. It was noted that the biodegradable household garbage mainly included food waste, waste paper and wood chips, with the amounts being 31.56, 29.55, and 6.45 million t·a− 1, respectively. Accordingly, the nitrogen reservoirs were 65.31×104, 6.80×104, and 3.81×104 t·a− 1 in China. Regardless of provinces or provincial capital cities, there were significant positive linear correlations between the gross domestic product and the amounts of foods wasted, indicating that China’s fast economic development was at the cost of huge food waste. However, if the food waste were used as organic fertilizers, chemical nitrogen fertilizers would have been greatly reduced. We found that food waste nitrogen reservoir accounted for 86% of the total, with its nitrogen reservoir being equivalent to 11% of the amount of actual absorption for synthetic nitrogen fertilizers (6.20 million t·a− 1) by agriculture plants in the country. Our findings provided a scientific basis for the classification and utilization of biodegradable household garbage, ensuring food security, and eliminating environmental pollution.
