摘要：Methane fermentation has been a waste management technique
for years. The main advantages of fermentation include the production of
electricity and heat from biogas or biomethane, which are a source of
renewable energy. In order for the fermentation process to have good
economic indicators, the continuous monitoring of process parameters is
necessary. To control the fermentation process, an anaerobic test
determining the biochemical methane potential (BMP) is particularly
recommended. The disadvantage of this test is the long duration of
measurements. Nowadays, AT4 respiration tests are increasingly used to
assess the methane potential of waste. The main advantages of AT4 include:
the 4-day duration of the test, the simple method for implementation and the
possibility of applying the test to all types of waste. In practice, in most
cases physical (VS) and chemical indicators (TOC and COD) are used to
assess the suitability of substrates for fermentation and its effectiveness.
However, these indicators specify only the total content of organic matter,
yet do not give information on the fraction of biodegradable matter. The
article presents an assessment of the efficiency of fermentation substrates
selected from the agri-food sector on a physical, chemical and biological
basis and presents the correlation between these indicators.
