The current rate of development of grain-processing and meatprocessing
industries makes effective and cost-effective waste disposal more
actionable. The reprocessing of waste from the meat processing industry, which
includes waste water, formed directly in the production of meat and from cattle
manure, requires special attention. Biotechnological methods of processing are
considered a promising form of recycling food production wastes. One such method is
anaerobic digestion, which is a continuous multi-component process that transforms
organic material into finished products, such as biogas containing methane, water
vapor and carbon dioxide, through microbial activity.
The aim of this study was to investigate the joint utilization of rice husks, manure
and sewage from a meat processing plant by anaerobic digestion in a laboratory
anaerobic batch bioreactor for 10 days. During the study, parameters of influence of
the substrate composition on the efficiency of decomposition of organic matter, biogas
and methane yield were identified. A series of experiments investigating anaerobic
fermentation of substrates was carried out with different weight ratios of manure,
waste water and rice husks at mesophilic temperature conditions (36 ± 1°C). After
benchmarking fermentation mono-substrates and mixtures, the use of mixed substrates
for methane was proved to increase the degree of biodegradability of organic
substance waste.
