摘要：Industrial farms pose a serious threat to both people and the
environment. The reason is that animal waste are produced in large
quantities, which is a source of biogenic substances. Their irrational use,
which is often common on industrial farms due to the limited area for
fertilization, can lead to the eutrophication of water tanks and soils, and even
to contamination with heavy metals and disease-causing microorganisms
and pathogens. The economy of animal feces is accompanied by greenhouse
emission and odors, the resulting emissions of volatile compounds also lead
to the formation of acid rain. In view of the above, the possibilities of their
management, which will be safe for ecosystems, are being sought for. While
aeration, composting or fertilization of animal manure does not fully solve
environmental protection or profitability issues, their anaerobic treatment
allows not only for safe utilization, but also for energy production. Thus,
the possibility of managing animal waste from a poultry, cattle and pig farms
in biogas plants was presented. The presented calculations have slown
that using them as a substrate in the fermentation process allows for effective
utilization of animal manure being hazardous to the environment,
in particular in the case of industrial farms.
